PREPRATION ! -- Last
<> My activities can be
chronicled as follows: Photography and study of the larger
rock (see Fig. #1B-1a, Report
#1B), which was
atop rubble on the shore of "Boat Harbor"; several
visits [most of which were accompanied by others who also, for example,
searched for additional specimens] to the site where
specimen was found;
investigation of the literature, including maps and aerial photographs,
of the area; contacting people familiar with the history of
area to obtain
oral historical information about the site; visiting additional
nearby areas with similar rubble ground-covers; discussing facts
and fancies about preliminary conclusions and speculations with
several people, a few
of whom are noted in the Acknowledgments.
coming to Gros Cap in October 2009, a number of residents of Mackinac
which constitute the eastern part of
Upper Peninsula, have
had me identify rocks they have collected. Most of
those rocks have been stones picked up from glacial, glacio-fluvial, or
deposits within these counties. One of those specimens, a
i.e., a stone -- led to research and a tentatively suggested
historical role for
a small, near-shore area
southeastern side of Poupard Bay, which is in Moran Township of
Mackinac County (see Fig. #1A-1).
Readers should keep in mind, especially while reviewing Report #1A, the
fact that neither

professional activities have been in the fields of glyphology or
archaeology -- professional
archaeologists will, of course, readily recognize this disclaimer.

by road, the
near-shore area is only ~0.25 mile southwest
of the northern junction of Gros Cap Road and Michigan Route 2 – i.e.,
approximately six miles(atcf) west-northwest of Saint Ignace;

both the ?glyph?-bearing and
holey stones were conspicuous -- i.e., they appeared to be out-of-place in
this rubble deposit. Unfortunately, none of
these specimens were photographed in place; the photographs shown
as Figures #1A-3 & 4 were so-to-speak staged -- i.e., the ?glyph?-bearing
stone in Figure #1A-3 and the holey stone(s) shown in Figure #1A-4 were
taken back to the locality, placed atop the rubble near where they were
found, and photographed in 2017.

that it is unlikely that she would have collected the stone if the

#1A-4. Two holey stones atop rubble at Boat Harbor. [ As
noted in the text, the relationship is staged:
That is, the holey
stones were taken back and placed
atop "typical" Boat Harbor rubble to take this
photograph. Also, the
surfaces of these holey stones were cleaned with a bristle brush before
they were studied and these photographs
were taken. ]
might be argued that the differences that led to the
appearance of these stones were largely dependent upon
lithological differences between the ?glyph?-bearing and holey
stones and the more numerous,
"typical" fragments of the rubble. Additional facts and
considerations seem more likely to indicate
these stones were not part of the natural environment -- i.e.,
the likelyhood that the ?glyph?-bearing
and the holey
were brought to Boat Harbor. These considerations, especially as relates to the holey stones,
similar rubble deposits lack holey stones like those at Boat Harbor.
distribution of the holey stones in the Boat Harbor rubble
deposit is neither regular nor random; they occur(red)
sporadically in only a
part of the rubble-covered area -- i.e., in an area, approximately 40 x
50 feet, that constitutes
only 10-15 per cent of the total rubble-covered area (percentage
based measurements on the
Google Earth composite).
The number of these holey stones (~
a score) and their
dimension ~4 -
~ 9 inches with most of them > 6 inches) indicate that they
unlikely constitute a so-to-speak collection made by, for example, a
hobbyist. [ This aspect is noted because a critical
earlier version of this report noted, "They could have just as well be
'deposited' there ... by a youngster disposing of their (sic) rock
The just quoted comment leads to two additional facts, which relate
accessibility of the area and (2) its possible role as
1. For at
least the last century, the Boat Harbor site, though only about a
half-mile from Gros Cap Rd., has not been
accessible much of the time; currently it is inaccessible, or
nearly so, by land
after the rather frequent near-lake rain
falls and wind storms/falls(of trees and limbs) as well as during most
vehicles, snow-mobiles not withstanding). Along this line,
attention is directed to the soil map of the area (Whitney,
1997) and to features that
evident on the Google
addition, much of the time even when it is accessible, an
almost overpowering stench of
the adjoining swamp lands, a couple of which have to be crossed, has
very likely kept
at least some people from even thinking about going, at least by land,
to the area where
the stones were found.
2. Use of the area as a dump, at least for the last several
have been highly unlikely. This is so
because easily accessible, open
dumps have been and/or are
nearby -- one is less than a mile from the site. This aspect is
also supported by the fact that no other obviously dumped things are
or atop this
rubble. In addition, the sporadic distribution of these stones
within the given, albeit small, area would seem virtually to
preclude the previously mentioned possibility,
suggested by one reader of an earlier version of this report, that some
collector of such stones may have just dumped them here.
Suggestion of the
is strictly tentative:
The presence of the
"glyph"-bearing stones and
the number of the holey stones within a relatively small part of the
rubble at Boat Harbor may indicate that this area has served, during

It seems that this suggested possibility
may warrant the same fate
that a number

visits to the area
from Eurasia -- seem to have had. Consequently, my hope is only
that, it -- along with the other two parts of this
tripartite report -- may lead to
further investigation and well-based, acceptable
deposits were examined in July and August of 2016: Five of them
were either awash Lake Michigan or only few feet from, and above,
present-day shoreline. These rubbles are located
sporadically along Lake Michigan between the marshland southeast of
Pointe aux Chenes and "Sand Bay," which is near the northern end of
Boulevard Drive, about one half mile south of its junction
LaBarbe Road. In addition, a "high-level" former lake-side
rubble deposit that is one (1) mile east of, and approximately 155 feet
higher, than the Boat Harbor rubble was examined. These
rubbles were examined to see if any ?glyph?-bearing rocks could
be found in any of them, and to see if their populations of holey
stones is, or is not, similar to that found in the Boat Harbor
The above possibility
based on empirical

seems likely that their presence at Boat Harbor and their near
in nearby, near-shore, rubble deposits indicates
they were brought into the Harbor area, probably for some
reason and/or use.]
To summarize our observations:
contents of all the lakeside rubbles were generally
similar . NO ?glyph?-bearing
fragments were found in any of
these rubbles FEW, if any, holey stones
like those collected from the Boat
Harbor rubble were found in any of these rubbles.
-- Three "asides," however, seem noteworthy:
a. The high-level rubble
deposit contains a larger
percentage of well rounded stones. b. So far as
?glyph?-bearing fragments, see, Fig. #1B-ADa.
[AND] c. A few rather
large boulders at a couple of these rubble deposits have holes that are
similarly shaped to those of the holey stones on their exposed surfaces.
3. The general consensus that the patterns on the
stones were incised by humans (see Rpt.#1B).
4. The conjecture that the holey stones may have
used as anvils (see Fig. #1C-1). For early literature relating
use see Ritchie (1929); so
far as the Boat Harbor holey stones, see also Gray & Pape (2016)*3*/; [ and ] consider
use so far as removing the
shells of acorns etc. to free their "meat" for eating and/or for the
production of their oil (see Kuhnlein and Turner, 1991).
<-- [ It seems, however,
that several alternative, rather
diverse, uses may have
obtained -- e.g., associations of holey stones with healing,
legends and also their possible roles as
charms. etc. These
alternative examples are mentioned because, among other things, no
found along with the holey stones at Bar Harbor. <<-D: in the
for hammerstones!! -- and, perhaps it is worth noting --Whether
any are found or not, some
of the smaller glacio-fluvial stones in the rubble could
have been so-used in lieu of shaped hammerstones. In any case, if
any of these stones were as anvils and the main purpose was to crack
nuts and/or acorns, it seems unlikely that percussion marks would be
common on either the stone hammerstones or anvils. == To
date, no such
marks have been recognized on any of the Bar Harbor holey stones that
have functioned as anvils. Another aspect seems noteworthy:
All of these stones have undergone corrasion, which would have likely
eliminated percussion marks said to be typical of stones so used. ]
& Pape (ibid.) so record holey stones
found in Adams
County, Ohio, which closely resemble the Bar Harbor holey stones, and
note those stones as "Dating to the Late Archaic period
(ca. 8000-1000 B.C.)."
5. The fact
that Boat Harbor is currently the only "protected harbor" between
Straits of Mackinac and Epoufette (See Fig. #1A-1) seems
least passing consideration. <--
is true despite the fact
that only a cursory examination of charts of today's near shore
this area, topographic maps, and Google Earth aerial
views of the area and adjoining region indicate the existence of
several rather diverse
former shorelines. The point is, if the suggested possibilty has

Although one of the critical readers of an earlier version of
for this Report indicated that he thought the tentatively
suggested possible existence of the "port" at Boat Harbor to be
"farfetched," no alternative suggestion has been forwarded or suggested
to me. And, to date, I have thought of no alternative that does
require what I consider even "more ad hoc" whateverS! I only hope
will lead to a real resolution!!

Boat Harbor Holey Stones
of the several holey stones that were collected from the rubble at
Habor are shown in Figure #1C-2. These, indeed virtually all of
stones of this area, were within the same small part of the
rubble deposit where the two
"glyph"-bearing stones were found (see Report #1A). Although
stones made up
much less than one per cent of the total rubble fragments within the

sizes and shapes differ markely from other fragments in the

that, apparently because of corrasion, only the bottoms and near
of these holes are remain, AND
all of the holes are on only the two larger, relatively flat,
surfaces of the sub-prismoidal and roughly discoidal
stones -- i.e., the surfaces upon which these stones would have

are the holes of holey stones formed ?
following is a brief review of diverse origins that have been
suggested, most by non-geologists, to account for the formation of
stones that resemble those of the holey stones of Boat
A. Rock-boring clams –
The italicization of boring in this subheading is used
to distinguish boring from burrowing clams (see Stanley, 1970,
Rocks and stones with remnant parts of holes of similar shape and size
as those found at Boat Harbor have been reported to occur at numerous
places here and
around the world, and many of them have been observed, or concluded, to
formed by rock-boring clams -- e.g., those of the family Pholadidae
Miller(2007), and Seilacher(2007)].
origin seems best to explain the features of the Boat Harbor holey
widely held opinion that all recorded rock-boring clams have lived in
marine or brackish
environments is problematic -- see, however, comments included
invertebrate animal" bored the holes?.
invertebrates – Other invertebrates -- e.g., other Mollusca
moon snails) and some arthropods, sponges, sea urchins, and worms
known to have bored holes in
sediments or rocks [see
Frey(1975), Miller(2007), and Seilacher(2007)].
Weaver (2015), among others, notes that
"Some snails -- particularly moon snails -- soften a clam's shell by
a boring organ that produces hydrochloric acid, enzymes and other
substances. Then the snail rasps the softened clam shell with a
plate called a radula, resulting in a circular hole."
<- Although this is not the excavation of holes in rocks,
seems noteworthy in that it at least suggests that some combination
physical and (bio)chemical
may have led to excavation of the holes in at least some holey
stones. (Cf. item 5.)
2. Weathering – This
suggested origin requires a
conglomerate, like none I have ever seen or seen described, as the
rock -- i.e., one consisting of subspherical ovate
within a calcareous (e.g., dolomitic) matrix. That fact not
withstanding, it has been suggested that the "holes" in some holey
stones have been formed as the result of the “popping out of
pebbles” from these stones: “Eons of rolling … a lot can
happen when stones
pebbles lodged in the stone ... popped out! … [from] softer
the stone which wore away quicker, leaving a hole” (Niagra,
<- This suggestion, given in a narrative, seems to be a
and at least in part possibly given in jest(!?). To add to that
would think that the suggested sequence [note underlined (by me) part
leave only the popped out pebbles, not the rock from which they were
removed. In any case,
“popping out of pebbles”, thus leaving the holes, seems to be a highly
origin for holey stones. On
the other hand, this suggestion, if revised to indicate the
originally enclosed fossils rather than pebbles, and if their removal
to have been a result of differential chemical and/or physical
weathering, such an
origin would seem at least to warrant consideration.
3. “Pothole effect”
– "These [holey
stones] are created when the river current spins harder rocks that cut
softer rocks. Over time, a long time we think, the harder rocks
drill [into or even] all the way through the softer rocks." [This origin, the subheading
designation of which is mine, has been
suggested for holey rocks/stones in river (estuary) bars in
(Deneki Outdoors, 2014).] <- The
size of the
grain(s) that would have been required for production of each hole by
such abrasion, the conditions
to cause the required movements of the water, and the length of time
conditions would have persisted within the limited locus of
each hole -- all requirements for this suggested genesis!!
-- seem unlikely ever to have obtained. In addition, the
distribution, and bearings of the axes of the holes in the specimens,
those from Boat Harbor and those shown of similar stones from other
seem to preclude this possible mode of origin.

holes of some holey stones. (Cf. item 1B.)

only known that no fragments of these rocks that contain such holes

exposures of the
parent formations during this study. This
apparent absence, at least permissively, supports the conclusion that

One feature of
these holey stones, in particular, appears not
only to support that conclusion, but also to indicate that the
fragments were then in moving water: Nearly
all of the holes in these stones are on one of each stone's
surfaces -- i.e., their probable tops or bottoms whenever they were at
transport or, for example, movement imposed by breaking waves.
This observation and contention, if
considered in line with the widely accepted geological history of
indicates that the holes were formed when the fragments were in a
addition, it would seem to follow, that at least some of
corrasion of these stones also occurred during the same general
period; however, it also seems likely that at least some
of that action has taken place more recently; indeed, it is
at least intermittently even now!
"probable invertebrate animal"
bored the holes?
is not proved that any animal bored these
holes. If one did, the general shapes and
the holes in the Boat Harbor specimens, as well as the probable
which they appear likely to have been formed, seems to favor some
clam(s). This is so even though very few of the shapes
holes in the Boat
stones exhibit the overall shape (roughly
that of a de-tipped
teardrop) of borings known to have been excavated by such clams (see,
Fig. #1C-3a); instead, only the bottoms of all but a few of
"borings," if they are such, remain. There also is the question
as to why no
remains of a boring animal (e.g., clam) have been found in any
holes. One possibility is that they were dissolved; in any
case, rather large portions of the Boat Harbor
holey stones have been removed, for the most part by corrasion, to
produce the current characteristics of these stones and their included

how did these holey stones get to Boat Harbor?
to find possible answers to this question led to the
already noted examination of nearby, similar rubble deposits and the
tentative suggestion that a "port" was possibly beside Boat Harbor in
the past -- see Report #1A. [As noted there, it seems
quite possible, if
likely, that these stones, because of one or more of their possible

to Boat Harbor by humans, possibly in ancient times. Indeed,
possibilities seem to require what I consider even less
acceptable ad hoc
was the source of these holey stones?
seems worth consideration even though it may not bear directly on
either the tentative suggestion that is in Report #1A or to
this part (Rpt.#1C) of this tripartite report. Several
occurrences of loose stones, both natural and so-to-speak "collected"
to form such things as walls and landscape accents were examined to see
if they included any holey stones like those found at Boat
Harbor; shoreline and nearshore groups of stones from Epoufette
on Lake Michigan, through the Straits area, to the Les Cheneaux Islands
area of Lake Huron were checked; NO claim, however, is made that
all such occurrences within this area were checked.

3. Holey stones have long found roles in the Arts and
Crafts. These uses include such diverse
highly prized Scholar’s Stones, decorative stones for aquariums and
worry and “good luck” stones, parts of jewelry (especially
also parts of wrist and ankle bracelets), and as wind chimes.
particularly interesting “Scholar Stone,” which is referred to as a
sculpture, is now in the Art Gallery of New South Wales in Sydney,
Australia. Hauser (2014) notes in her remarks about that stone:
developed a complex connoisseurship of such phenomena … [This rock is
example of the sort of aesthetically pleasing stone that came to
gardens (and paintings of gardens) during the Tang Dynasty [628-907]. …
stones … were meant for gardens; smaller ones, [also] known as
stones’, . . . sit on desks as an aid to contemplation.” ]
Holey Stones have attracted a rather large following
among people who associate minerals and rocks with the healing of
mental conditions, enhancement of meditation, etc. Consequently,
advocates ascribe all sorts of attributes to these stones, and
extolled these claims and repeated diverse versions of "myths about
stones" in their brochures and advertisements.
Some so-called holey stones that are in the
marketplace have been manufactured. Examples are those replicated
silicone, and some of these have had their surfaces plastered by a
consisting largely of crushed rock (Holey..., 2016). Most of
so-called "holey stones" are apparently sold for use in aquariums and

"structure" is an example of accumulations of stones with
similar upland locations within the area. Each of these stone
piles is considered to be an ancient artifact by the local people who
know them well. Some of these people have
beliefs that the piles were likely made by, for example, neolithic
"stone-age" aborigines, Celtic Druids, Vikings or pre-Columbian Native
Indians. Whomever, it seems safe only to say that these
"structures," at least this one (the only one I have examined at all
closely) were made after the
last removal of glacial ice from the area -- i.e., ~ 11,000
shapes and topographic
locations of these
accumulations of stones are
frequently cited to
hypothesis that they are meaningful artifacts -- i.e., they are not
that were put where they are in order to clear the nearby fields. In
this aspect of that hypothesis, it is quite evident
the land surrounding this accumulation of stones would
have never been cleared for, for example, any at all extensive farming
map); also, had that been the purpose, several stones that I believe would have
been removed and become part
of this group would no longer remain the surrounding area -- but they do!. In addition, it
seems noteworthy that this
structure is on what would have an island in during
the so-called Algonquin and Nipissing stages of the Great
Lakes. And, if only a few or no trees etc. were then present,
areas of the lower-level Lakes Chippewa and
Stanley as well as of the more recent, and
Lake Huron and the Straits of Mackinac could have been seen from this
professional archaeologist is said to have looked at this group of
stones and suggested that this
structure represents a "post-American Civil War lime kiln."
that I have seen or been able find nearby seems to support that
suggestion, and the presence and lack of certain characteristics seem
possibly even to
preclude this origin. The only other suggestion that I have heard
it may have been a place where fires were built to heat maple sap to
make syrup. Consequently, the given heading seems appropriate
until the origin(s) and use(s) of this and possibly other accumulations
in similar settings are proved.

of this roughly
is approximately 55 feet; the "diameters" range from about 16 to
20 feet; the inside diameter ranges from
approximately 6 to 8 feet; the height of the wall, the top of

to 4½ feet above the surrounding

close-ups. That is to say, both stones from the rubble of fairly
nearby formations and stones
transported from Ontario by glacial ice
during the last "Ice Age" are included. This makeup, of course,
is one of the criteria that establishes the date of creation of the
structure as post-"Ice Age" glaciation.
topography of the
nearby area led to my
thinking of this structure as roughly resembling a
multi-jeweled pendant on a dowager's
breast --see the section of the
included (above) topographic
map of the area. As might be expected, other people who are

get Mike's thoughts and to give them here. ]]
#3. What? near St. Ignace, Mackinac Co.,
remarkable dome-shaped fieldstone structure is in St. Ignace
have arisen and virtually no answers have been found support with
origin or its uses. Historical data are lacking, or at least not
yet discovered. I am neither an historian nor an archaeologist,
and to date my attempts to get any professional in either of these
fields interested in the structure have been in vain. Consequently,
questions -- such as Who Built it?; What was its function, either
real or projected?; and When was it built? -- remain unanswered.
following possible origins
and uses, which have come to mind or been suggested to me, are given
here with the hope that recording them may lead to an
appropriate investigation and understanding of the structure:
1. Kiln – for production of lime or charcoal
2. Sepulcher – for use as A.a Burial vault and/or B.a Receptacle
for sacred or otherwise valued whatevers
3. Signal mound – i.e., a site from where smoke signals (etc.) may have
4. Root cellar
5. Meat Preparation – e.g., to smoke and/or otherwise cure meat
6. Hunter’s blind
It is my belief that: The Kiln
possibility (#1) is precluded unless some substructure, now removed or
is found. The Sepulcher (#2) and Signal mound (#3) uses seem
unlikely because of the dates such structures were likely used in this
area; however, if it is shown that the iron “pipe” (see diagram)
was added well after
the structure was first made, one or the other of these functions may
have prevailed or at least been anticipated. [ and ] The overall
structure -- e.g., its shape, size (especially the height), masonry and
access -- seem not to correlate
with what one would expect for any of the the other listed possible
#4, #5, and #6,
except possibly #5). In
without checking to see if, for example, there is any substructure or
if any bones or relics are directly below the exposed floor, it seems
that the origin and use(s) will not likely become known for sure.
An aside: Other
origins, which seem not to warrant inclusion on this list have
been given, most of them in jest -- e.g., a place for one to send an
unwanted guest. However, this latter example has made me
wonder and even think that perhaps the structure was built for and
used as a place where
had broken some law, tradition or the like might have been
incarcerated -- i.e., a place
for "solitary confinement." Among other things,
the placing of a lid over or putting a so-to-speak stopper in the hole
top would have made it virtually escape-proof. (( No lid
or the like or an alternative, such as a "ball
and chain," has been found. )) .
the soil cover and
growth (upper photograph), this structure appears to be well
preserved -- note the general character of the constituent stones and
of the masonry that is indicated by the inside side of the structure
(lower photographs). The following summary is a of the things
that are currently known about the structure -- in reviewing them,
see also the diagram, which is based on measurements that Charlie Brown
and I made August 31, 2010:
The structure is dome-shaped with a hole at the apex of the dome. The
four lower photographs show the hole and the general character of the
constituent stones and masonry, albeit deteriorated, as it is exposed
on the inside wall.
higher side of the structure, on the left as shown, is near an outcrop
of the Mackinac Breccia similar to that of the so-called stacks that
common within this general area. The linear group of curved lines
on the inset of the plat map seem likely to represent this outcrop.
The only apparent access to
the interior of the structure is the hole near the
top (center, left photograph) – i.e., no other opening large enough for
access is apparent in the walls above the currently exposed interior
The roughly circular area
surrounded by spoke-like lines that are on
"Whicher's Plat of Scottville," which is dated March 15, 1851, may
represent this structure -- see inset (The red arrow on the inset,
which was not on the original plat, points at the just mentioned
symbol.). IF this symbol does represent the structure, it was
built before the mid-1800s. [[--By the way, the circle below
this symbol, which is around the letter "D," which is rotated ~90
clockwise from its normal position, has nothing to do with this
structure other than its location.--]]
The iron “pipe,” the position
of which is shown on the diagram, was
highly corroded, but still cylindrical (diameter ~3 ½
inches) and magnetic, when we found it. It was on the opposite
side of the structure that is shown in the top
The overall structure is now
covered with biological matter that
includes the major roots of the trees. The size of the larger
cedar trees that are growing on and near the structure have
circumferences of ~6 feet near their bases; they have been estimated to
be 90 + 30 years old
(Steve Sjogren, p.c., 2010).
Notice: The following is a preliminary ("working ...")
manuscript and a "To do"
list -- i.e., observations and measurements to be made and photographs
taken during a revisit, IF such occurs,
to the two pop-ups. A revisit,
which was scheduled for July, 2016, became untenable -- the owner of
the property where the Cushing pop-up is located indicated to my
Hammond correspondent that his bull
and cattle would be
that field during that period. Perhaps a
2017 visit will become possible; perhaps, some nearby geologist
geology student will pursue the study in the future and
find the following helpful.

PETROGRAPHY. The Potsdam Sandstone within the area is described by
p.179) and Dietrich (1957, p.101). The strata involved are
silica-cemented, medium- to coarse-grained, well-rounded quartz sand, a few lamellae
of which consist largely of hematite-coated grains. Depending

variable thicknesses of this Cambro-Ordovician formation within the
area are described by Cushing (1916, p.32 et seq.).
DATE OF FORMATION. The fact that the two pop-ups were formed since the last
glaciation of the area is indicated by the presence of glacial striae
and chatter marks on the upper surfaces and their absence on the other
surfaces of the blocks of these structures. None of the the
names, such as Wisconsinan, are used for the glaciation involved in
this note because the assumptions
upon which they were based have subsequently been concluded to lack
their originally assigned application.

geology of Hammond township (Dietrich, 2008) .

to the axis of this pop-up are nearly vertical but they range from relatively
smooth to highly irregular --
see Fig. 5-#X. (what
about space between blocks on same side?? do they match -- i.e., except
for post-fm erosion?? -- how much erosion?? OR were they
separated in that direction when the structure was formed?? --
was there "stretching parallel to axis??)

are approximately parallel to the axis are

they be matched like jig-saw puzzles ????)
b. The broken surfaces of the

also are approximately parallel to the axis of this structure are
they even be seen??? if so, can they be matched like jig-saw
Only a few of the broken surfaces that so-to-speak define the axis of
the structure overlap as indicated by Cushing (Cushing et al.,.1910 -
p.116, Fig.10) -- instead, nearly all of the blocks
that are on the northwestern side of the apex overlap the blocks on the
southeastern side -- (see Fig. 5-#X Calaboga 8&9). However, considering
the fact that Cushing's indicated height of the apex is significantly
greater than it is now (2016), the following question and comments seem
noteworthy, and possibly
explain this discrepancy in Cushing’s recorded observations and those
made during this study. Have
the blocks moved outward from the axis --
i.e., undergone post-formation partial collapse? since Cushing mapped the
structure in the early 1900s (See if their bottoms are atop the
surrounding, nearly horizontal ss OR are they still so-to-speak "stuck
in place" (i.e., have their ends adjaent to the top edge of the surface
from which they broke off (<< --Wow -- what a
description!!!) -- Along this line, one or more of the following
activities may have occurred and, if so, would support
an affirmative response: a. Trees have grown in the
axial since Cushing's observations -- (see Fig. 5-#XCalboga
9). (Tree wedging – e.g., see Dietrich (1957, p.21, Plate 6) --
provides permissive support so far as their having a causative role for
such movements of the blocks.) b. The surrounding, nearly
flat bedrock is exposed on the southeastern side of the structure
whereas the other side is covered by soil; and slipping
atop the exposed rock, possibly enhanced by seasonal ice build up on
the surface of the flat-lying, surrounding sandstone would
likely be away from the apex, mainly to the southeast. AND, such
movements would result in the apparent change in height and possibly
also account for the apparent differences in the character of the
overlapping relationships along the crest of the structure.
Strikes & Dips of nearby
The two pop-ups may have similar or different origins;
this may be true so far as both the pre-formation controlling
conditions of the rocks and/or the causative triggers (see COMMENTS …). No origin has been
or is herein suggested for the Hadlock pop-up. Several comments
about the possible origin of the Cushing pop-up are in the literature
(e.g., Cushing in Cushing et al, 1910; Twidale
and Bourne, 2005; and Jacobi
et al., 2007).
Two considerations indicate that only a comment about the an
origin should be given in this note. This is so because: 1. No data (i.e., values)
relating directly to the stress -- internal/residual/compressive -- of
the sandstone of either of these structures or the surrounding rocks
are available. 2. Two
seemingly significant references-- i.e. Dames and Moore, 1974 and
Smith, 1977 -- that pertain directly to the Cushing and other nearby
pop-ups have been unavailable, even via ILL. 3. The required
considerations for making such conclusions should not be made by one
with my background. -- The comment is:
I think that changes
of conditions -- e.g., those that accompanied deglaciation and/or
post-last glaciation isostatic rebound -- had major roles in
both the build up of internal stresses and their release, which led to
the formation of at least some pop-ups; and, the release of the
stresses seems likely to have been abetted by “triggers.”
comment is based
largely on impressions gained from: a. data recorded in this
note; b. a review of the available literature relating to pop-ups
and the pertinent tectonic domain of the region; [and] c.
considerations relating to Lowry’s (1959) and my (1961) investigations
of the Mt. Airy “granite” and the subsequently determined residual
tress information, which was obtained by U.S. Bureau personnel who
utilized sed overcoring procedures of in situ rock at the North
Carolina quarry. Their results were concluded to indicate that
the conditions were “ripe” for the continual formation of additional
buckles at the quarry.
further, the following thoughts have arisen in my mind several times
since I again saw the Cushing pop-up and had my attention directed to
the Hadlock pop-up:
axes of these pop-ups have different strikes; in fact, the
Hadlock structure has a bifurcated, albeit continuous, axis -- i.e.,
the strike of axis of one of its sections, differs from the strike of
the axis of the other section. In addition, none of these
strikes appears to fit any obvious pattern or to correlate with
the current, granted, less than well-established, regional
structures appear to have been formed after the last glaciation --
i.e., after the
load of glacial ice, plus its debris, was removed -- and during the
subsequent, still on-going, isostatic rebound.
so-called “trigger” could have been instantaneous or a slow
(i.e., a gradual change in the position and condition of the rock
until a critical condition was exceeded). Two examples of
the latter might be the removal of the glacial ice and its load
(and/)or the subsequent isostatic rebound – i.e.,
when a release of the compressive stresses within the rock exceeded a
value whereby formation of one or more pop-ups was
[[ ((---No stress
measurements for rocks of either pop-up or nearby equivalent strata are
known, and cannot, in any case, be determined exactly for the time the
area pop-ups were formed. It can, at best, be hypothesized that
the horizontal stress(es) exceeded the vertical -- i.e., upward --
stress. If, however, current measurements of the internal
stresses of the rocks of these structures and of similar near-surface
Potsdam sandstone in the area were made, possibly those data could be
programmed to create a model that might indicate -- i.e.,
so-to-speak replicate -- the approximate previous conditions, and
perhaps even how these pop-ups may have been formed be it
initiated by a
"slow trigger" or by a trigger per se. -- See paragraph XX in
the following Comments and Questions section.)) ]]
following??!! As I typed the above comment
plus, two old “saws” came to mind: “Fools rush in where
wise men fear to tread.” and “There’s
no fool like an old fool” (I am 92 years old).
It seems prudent to preface the paragraphs of this section
with a disclaimer: Because
of my lack of access to some of the publications I believe I should
review, readers are urged to insert So
far as I know before
each of the following paragraphs.
first five of the following paragraphs relate to the possibility
that burial beneath
thick glacial ice had a role in the formation of these pop-ups.
No pop-up in this region has been recorded as
having been formed before the last glacial epoch. Does this mean none
was formed? OR Were such pop-ups,
if formed, disrupted, their parts moved and thus not recognized as
having been parts of a pre-existing pop-up? -- So far
as the first question, three things may have precluded their earlier
Strata susceptible to disruption and formation of pop-ups may not have
been at or near enough to the surface where they could form -- i.e.,
pop up. 2.
During earlier glacial and interglacial epochs the strata were not
buried deep enough to gain the internal stress conditions required for
release and formation of pop-ups. 3. Whatever the
depth of burial by the glacial ice (etc.) and the resulting condition
of the the strata, earlier rebounds were insufficient to change the
environment of the rocks to the point that formation of pop-ups
of course, some combination of these possibilities plus other things
might have been effective controls. In any case, IF
either the second or third possibilities prevailed, they would have
implications so far as reconstructing the Pleistocene history of the
To continue this
line of questions/thought: Was the glacial ice
plus its load during the last glaciation of this region thicker, and
thus heavier, than that of earlier glaciations? If it was, the
Potsdam Sandstone that constituted these pop-ups would have been buried
deeper -- i.e., have undergone a greater downward depression -- than during preceding glaciations, and compressional
stresses built up within those rocks would likely have been greater
than during earlier glacial epochs.
Consequently, this latest post-glacial isostatic rebound, which is
occurring, would have caused these rocks to have undergone greater
changes than those to which the rocks had been subjected in response to
earlier glaciation and rebound. In addition, the current
bedrock surface may not have been at or even near the surface of relief of stresses before the last deglaciation and
this line, what is really known about the thicknesses of the last
continental glacier within the region and of earlier Pleistocene ice
sheets that covered the region? Are dates indicating
their longevities really indicative? Is there any known correlation
between durations of continental glaciations and their thicknesses(?),
of the amount of erosion they caused(?), ...? Is, for
example, the distance that
the different glacial ice sheets extended southward related to their
"up-stream" thicknesses? Does the size and
distance of travel of erratic boulders during any given glaciation have
a relationship to the thickness of the glacial ice(?) to the speed of
movement of the ice and its load(?), to the amount of erosion caused by
any given glaciation(?) …]
Could a so-to-speak "fatigue" have been
involved? Is it possible that
more than one depression (for this region, multiple periods of
glaciation) and subsequent rebounds had a role(?), OR even were
required, for the formation of the pop-ups in these rocks? [This multiple
question is prompted by changes and effects known to be involved in
breaking, for example, metal sheets, rods, etc. – i.e., those that
break only after having been bent and straightened several times.]
Could the occurrence of these pop-ups indicate that the
strata involved were only finally thinned enough by, for example, the
last period of glacial abrasion, to the point that they could no longer
retain their integrity – i.e., thinned to the point that they could be
broken to relieve the residual stresses within them. [If this was a
control, it seems likely that it must have been only a subsidiary
control. Among other things, the thicknesses of the
strata involved in the Hadlock and the Cushing pop-ups differ markedly,
AND, several extensive areas with thinner, apparently similar Potsdam
Sandstone strata, now exposed bedrock, with no pop-ups occur within
Are more pop-ups
likely to be found with the area? This possibility
came to mind because of an inquiry by a geologist who read this
manuscript; he reminded me that both A.F. Buddington, who mapped
the area, and I, who lived in Hammond for many years and mapped an
adjacent quadrangle, were basically hard-rock petrologists, and
consequently may have had our minds on other things as we passed the
Hadlock pop-up. -- Along this line, I feel
"Budd" did not see it, or he would have told me; I know that I
did not see it even though I drove past it hundreds, if
not thousands, of times. I first saw it in
2007 when the landowner took me to see it -- more than 65 years after I
first drove past it IF it
was then there. [That
"IF ..." is based on the possibility that this pop-up was formed
sometime between about 1952 and 2006. In any case, I shall
continue to question people who might have information that would
preclude or support this possibility.] Here may be where I could/should?/ . .
. go into several things, for example:
Omar, Oak Point, Alex Bay ones Wallach mentioned.
indicating unlikelihood of any of these formations retaining an
integrity that would be called tent-like once fracturing to form such
occurred -- i.e., they would have collapsed and appeared more like (prepare a "step-wise"
series of diagrams --
along this line, Figure 5-#1 would seem to be a "middle of the road"
example??? ) and thus likely so-to-speak not be recognized,
that may lead to all sorts of additional thoughts/considerations.
seldom readily determined, aspect for
which very effort should be made to find and describe, especially if
the feature involves stratified rocks relates to the following question: Is only one relatively
group of strata (i.e., only the exposed (i.e., top) ones, with air
directly atop them) involved in one or the other or both of these two
pop-ups OR Are several
visible or even relatively easily found, strata also involved? This aspect became
recognized when my possibly wrong-headed thinking re the Cushing pop-up
became no longer the relatively simple structure that I had in mind
because I related it to what I had seen at Mt. Airy.
<<< needs more description,
some photos/other illustrations, etc. It also makes
idea of the collapse of such features become a structure by structure
consideration; that is to say, only those that involved one relatively
thin group of coherent strata exposed at the surface would likely
collapse, and consequently not be recognized. [[The alternative
seems to be exhibited by the photo of the Alex Bay one sent by
Wallach -- see!
]] << preceding can probably said
more succinctly by considering post-formation stability -- i.e., are pop-up
features that consist of only
a thing group of strata, with air below as well as above, more likely
to collapse than those held up by underlying also popped-up strat
(Wallach's Alex Bay photo -- see!).
thing for which I should search and measure/photograph: Is there
any remaining suggestion of a curvature (i.e., convex upward) of the
blocks on either
side -- i.e., one that might be seen as part of any pop-up formed
the general way that the Mt. Airy structures were -- i.e., with a
pre-fracture "bulge." -- look

differences that might indicate the popup rocks were once under
localized stress -- along this line, CHK!!
the characteristics of the Broken surfaces to see if they, for example,
exhibit the typical indiscriminate crosscutting of matrix and grains
that characterize orthoquartzites OR ???. ...
All such things might, along with other things, lead to information
would indicate whether any given structure was formed so-to-speak as a
consequence of a "slow trigger" or an all at once one-- i.e., perhaps
just uplift and final relief of compression versus some
ANOTHER aspect (alternate overlaps) may

overlaps indicate or at least serve as permissive evidence for slow
trigger (e.g., rebound) fm., whereas all overlaps from the same side
MIGHT indicate tectonic activity of some sort as causative. Here, it might(???) be

granites ( mid-20th century ) ]]. Eclectic!!
????????You ask about reasoning
regard to thin
sections. It was just that I thought a comparison of the thin
sections might show a difference which in itself would give an
indication of the process leading to the formation of the pop-up in
that location � such as signs of localised stress
ffor instance. From
your comments it appears that you have done quite adequate thin section
work which shows no localised factors.??????
following comments include a maxim, two "wonders", and “triggers”.
Pop-ups can only
form where a sufficiently large "free space" exists in direct contact
with or relatively close to their constituent rock formation -- i.e., a
space into which the rock can "burst." Therefore, a pop-up
can serve the same role as an unconformity so far as interpreting
One wonders if the
fact that the Hammond pop-ups are on so-to-speak high areas had any
effect on their formation. – The Cushing pop-up is on a “high” between
the St. Lawrence River and Chippewa Creek valleys; the Hadlock pop-up
is on the "high" between the Chippewa Creek and Black Lake valleys.
One also wonders if the presence of many pop-ups,
including those near Hammond, New York, within so-to-speak relatively
stable areas, the bedrocks of which have undergone continental
glaciation and rebound (i.e., development and release of high in situ
stresses), is more
significant than any tectonic event, and perhaps all that is needed, so
far as production of these pop-ups.
– Nearby blasting could change conditions, perhaps by slightly jarring,
a rock in its near-critical condition and thus trigger formation of a
pop-up. Time of its formation appears to preclude this possibility for
the Cushing pop-up, but perhaps not for the Hadlock structure.
Earthquakes – Associated movements may cause, or I suspect
even be the result of, the formation of pop-ups. A recent example is one that formed near Menominee, Michigan
in 2010. It seems
that either, neither, or both of the Hammond area pop-ups may have been
Encircled plus – This, “far
out” possibility came to mind during the 2014-15 winter when I saw an
pop-up like structure that consisted of relatively thin (10-15 cm.)
blocks of surficial ice in a bay near the northern shore of Lake
structure appeared to have been formed when the “buttressed”
ice had expanded to the point that it became too large for the confined
space that it occupied. Granted, that feature apparently formed as a
consequence of the expansion that occurs when water is frozen to ice
within a confined space, and rocks tend to have their volumes reduced
but ...; and, what about the admittedly remote possibility that
some rocks with high porosities (and permeabilities) might be so
affected(?). Also, along this line, might freezing of water in
nearby joints or along certain strata have any role?
might heat a rock so that it expands beyond some critical state thus
causing it to form an pop-up. (Cf. Thermal
Lightning strike – This
suggested by local inhabitants for all sorts of things, including
formation of the Cushing pop-up, appears consequently to warrant
mention. And, it is known that mechanical stresses are
associated with electrodynamic forces associated with lightning;
and Grab (2014) have recorded disruption of
rock that they attribute to lightning. In addition, lightning
is known to have set fires, and thereby have been an indirect cause IF
fire ever acted as trigger -- see preceding entry.
Meteorite impact – A true trigger, and possibly a cause,
wherever a meteorite might impact rock, the condition of which was at
or close to a critical state stress-wise so far as becoming an pop-up. Along this line, it
might be worthwhile to search for meteorites in the vicinity of
pop-ups. AND, If possible, one
should search within the open-space beneath the blocks of an pop-up, to
look for shear cones (see Lowry, 1959, p.1; and Dietrich, 2008, cover
about the guy who gave me the latter -- one shown on Mimetolith web
possible, contact him through Donna/Nancy! – I need to know if it was
made by man-imposed percussion or if perhaps there is a pop-up where
he found it!
Sheeting (i.e., "Off-loading
joints" of my youth)
of some, for example, underlying granite – Could
of an underlying formation, whatever its cause, act as a direct
"trigger"(?) or perhaps be indirectly involved as open places into
which water could get and freeze and expand? [So far as the two
pop-ups described in this note, it seems likely that granite
that exhibits sheeting is beneath the sandstone of the Cushing pop-up,
and that the identity of the rock beneath the sandstone of the Hadlock
pop-up may be the same, but is less comfortably so-predictable;
this is so because, to
date, pertinent well driller's data have not been found.]
insolation, is of
special interest for two reasons: 1. This possible
"trigger" reminds me of one of my favorite phrases in geological
“literature,” one I first found in the early 1950's – “horizontal
expansion of superficial strata, consequent on postglacial amelioration
of climate“ (Gilbert, 1887). [and] 2. It reminds me of the
great experiences Wally
Lowy, our students,
and I spent at the Mount Airy "granite" quarry where we were
repeatedly reminded of the seasonal -- i.e., warm weather
-- times that were known as the times when most of the “expansion domes” were
Miscellaneous 1. Could the
existence of post-glacial Lake Iroquois, which covered this area, have
had any role in the formation of these structures?
2. Could permafrost
have had any role? This question relates to the
appearances of pingos and hypotheses for their origin -- e.g.,
Alaska (see Holmes, Hopkins & Foster, 1968).
3. Earth tides (more needed here re such!!!),
What about the several additional triggers, including “slow triggers” –
i.e., those processes thought possibly to have led to gradual changes
conditions -- that have are not included in the above list but have
been suggested for other pop-ups and similar features? -- See, for
example, those that are tabulated, along with references to papers
about them, by Steck (1999, p.8, Tbl.1.2).
??? Would the
presence and removal of approximately the same
thicknesses/volumes of glacial deposits (e.g., till) versus glacial ice
lead to same result so far as ... ???

If time, check to see if there is

related to the tectonic trends widely
associated with the
this line, so
far as my observations and records in the literature,
no pop-ups or evidence that have been recognized as possibly
earlier glaciation and rebound.
above is based on some information/perceptions that certainly are
question(other possibilities): The fact
that these two pop-ups were post the last glacial retreat is indicated
already mentioned fact that glacial striate/grooves are on only the
nearly horizontal surfaces of the involved blocks.
But, the fact that there seems to be no
indication of such “structures” related to other glaciations may only
the fact that any evidence of their existence was subsequently removed. ?However, it may be that there less deep
burial and rebound during the interglacial periods OR that the time was
short during those interglacial periods that rebound did not occur
occur to the extent that it has since the last glaciation.
One needs to search the literature (and the fields!!) to see if
are any features that give any sorts of answers to these AND OTHER
questions! ! For examples:
Did the last glaciation involve a greater thickness of ice
weight) in this area than prior glaciations(?), etc., etc., etc
the pushing of the blocks on the river side over those on the other
side was by
ice (especially late glacial advances) that changes the time of the
of at least this pop-up to pre-some/most rebound!!!
And, there are
of formation: The following
relates to information given about one or more pop-ups that have
occurred recently (e.g., one in the Upper Peninsula of
Michigan): So far as the two Hammond Township
structures: This does not
the Cushing structure; although unlikely, it may
relate to the
Hadlock structure: Are the bushes (and nearby trees?? -- I
do not recall any) growing perpendicular to their bases or do they, for
example, tip in a direction that suggest that the structure formed
relatively recently. Among other things, check
positions of plants atop pop-up blocks versus those of nearby plants.
Also, in the case of the MI one, it seems worth checking the crack
separated trees (& other plants?!) from their roots. if any.
And. the MI upheavel led to a deep booming
sound,...shaking nearby homes... -- Are
there any "oldsters" who
live near the HADLOCK pop-up who recall such (or heard, for example,
their parents talk about such)??? -- If so, see if any earthquake
records support any such occurrence centered here or near here.
