|In 2005 Dave
Gillilan, a house builder and farmer, contacted this author to
report finding artifact material like that shown elsewhere on this
website. The fact that he was seeing the same morphology
and incorporated imagery in his lithic material was very interesting but not surprising or remarkable considering the many photos of this that had already been
contributed by other visitors. In October 2005, Dave took some of his
finds to Columbia, South Carolina, where this author was attend-
ing the Clovis in the Southeast conference (including Topper,
etc.). Close inspec- tion revealed that the morphology and
imagery in these were indeed essentially the same as in the
Day's Knob (33GU218) artifacts, although generally of
more refined workmanship.
In May 2006 this author
visited Dave at his home to photograph the material. In
the meantime, Dave had found, just below the surface of a
crawlspace in a house he was building, the
material shown on this page at about 1.5 m (5') beneath the
surface of rural terrain that was undisturbed below a plow zone
of about 20 cm (8"). Within glacial till (clay), the artifacts had been
placed in a horizontal layer of sand that was not parallel
to the sloping contour of the terrain. Most of them were like those viewed in
but accompanied in direct context by a cache of flint, quartz,
and calcedony points, blades, and scrapers that have since been
professionally charac- terized as Late Archaic and/or Early
Woodland, from very roughly 2000 years BP. These
identifiably "Indian" objects seem to offer some hope of gaining
professional attention to the material as a
whole, including the more controversial artifacts. Com-
plicating all this a bit, and rather intriguingly, in direct
context were clearly manmade objects of glass,
iron (radiocarbon dated), and concrete
incorporating the simple bird and bird-human imagery characteristic of
very old Native American artifact material. This could (should) become interesting...
There was no professional
interest in assisting with or even witnessing the retrieval of
this material, and it is most unfortunate that, as a result, its original
context and its removal were not properly documented or
To demonstrate the important
"replicability" factor, some of the artifacts shown here are accompanied by
references to similar ones at the Day's Knob site.

x 1.5 mm.

Woodland age. It seems
out of place, to say the least, but it is the author's opinion
that Dave would have not "planted" it. Also,
there were numerous artifacts (a few shown below) and
byproducts in direct con- text that strongly suggest an early
glass manufacturing technology. (For what it might be
worth, note the general resemblance to the early Adena Cresap

Possible evidence of prehistoric
iron smelting has long been recognized in Ohio, as at the well
Hill walled earthworks site in Ross County, close to the
location of Dave Gillilan's finds. It is fairly common in
the vicinity of Hopewell earthworks, but summarily dismissed by
archaeologists as an "intrusive feature" on the
patronizing assumption that "Indians" were not capable of this.
Even the few earlier (exclusively avocational) investigators of the
evidence in Ohio
who have recognized this as convincing, (e.g., Arlington Mallery and William
insisted it must be the work of Vikings (had to
have been white people, right?).
Native American Lead Smelting in Indiana?
January 2011 National Public Radio's news program All
Things Considered aired a feature on recent
discoveries at the Mann Hopewell earthworks site in
southwestern Indiana, with the statement that one of
these "could rewrite history books".
"...scientists are starting tests on what looks
like evidence of lead smelting, a practice that, until
now, was only seen in North America after the arrival of
the French, 1,000 years after the Hopewell Tradition."
Apparently this the first time that
archaeologists are recognizing the idea of metal ore smelting by
prehistoric Native Americans as plausible. Daring,
to say the least. It will
be interesting to see how this develops...
It is noteworthy that none of
the iron and slag artifacts in Dave Gillilan's cache have any
apparent utilitarian function. They seem to be of an iconographic nature, and it appears
that this was the main or only purpose of smelting technology
here. (And it is interesting that in ancient Siberia
and Africa, iron smelting was largely the domain of shamans
[ref. Mircea Eliade in his encyclopedic work Shamanism].)
Of course there is the
awkward fact that Native Americans are not recorded as engaging
in iron smelting at the time of European contact. This
author's tentative hypothesis is that this time-consuming and
labor-intensive technology with no perceived practical application was abandoned
(and subsequently forgotten) around the time of cultural decline
corresponding to the transition from the Middle to the Late Woodland
survival-related concerns became paramount.
The anomalous and
"problematic" material in Dave Gillilan's finds will
be scien- tifically evaluated as time and other resources
permit, leading to whatever conclu- sions may result. This
is, of course, a strictly avocational project, as professional
and academic archaeologists seem, for the most part, to have
little interest in things beyond the realm of what they have
been taught to expect. But things are whatever they are, and the
scientific method dictates that unexpected phenomena be examined
and evaluated in terms of actual physical evidence rather than
sum- marily dismissed because they do not fit within an
Radiocarbon Dating __________
The carbon content of the
iron artifact shown above (presumably from charcoal fuel used
in the smelting process) was radiocarbon dated at the
University of Arizona's AMS laboratory in 2007. The
carbon content of the tested sample varied from one segment to
another, one showing 0.007%, another 2.2%, and the rest in the
range of 0.04% to 0.08% - altogether much less homogeneous
than what one would expect in recently manufactured iron.
Readings from three separate samples with sufficient carbon indicate
about a 90% probability of origin somewhere between 209 and
783 AD, the two more closely corresponding readings indicating
209 to 551 AD, alto- gether coinciding more or less with the
Middle Woodland Period. Click on the image below to see
charts of the readings calibrated against the IntCal04
atmospheric curve using Oxford University's OxCal software:
this is quite interesting, suggesting that the iron
is roughly contemporaneous with the
diagnostic Native American
artifacts in direct context, one can say with certainty only
that these are the numbers returned by the radiocarbon
dating process. At best, carbon dating is a tricky business with many pitfalls, and
the dating of iron is even more so than that of other
materials. Altogether, there remains a lot of
time-consuming and expensive research to be done.
Compositional Analysis __________
testing the hypothesis that the iron is prehistoric in origin,
it was deemed neces- sary to determine whether or not it
contains elements exclusively characteristic of recent alloying
processes. A sample (shown below) like the one dated, and
from direct context in the find, was analyzed by EDS
(energy-dispersive spectroscopy) and WDS (wavelength dispersive
spectroscopy) at Yale University.
carbon content of a fragment of the specimen, determined after
anneal- ing and cooling, was less than 0.1%. From EDS
and WDS, the non-metallic content of another fragment of this
was found to be primarily manganese at 0.3%, with smaller
components of silicon and sulfur. No distinctly modern
alloying content was detected.
comparison, this sample of southern Ohio hematite ("bog
ore") was an- alyzed by ICP-MS (inductively coupled plasma
mass spectrometry) at NSL Analytical Services' laboratories in Cleveland:
material was determined to be more than 10% iron (no surprise), with
aluminum, calcium, and silicon each comprising between 1% and
5%, manga- nese being between 0.5% and 1% of the whole.
Altogether, melting this ore would likely produce an iron with
the composition of the iron artifacts shown above. A fire
raised to a temperature of around 1000 degrees Celsius would be
required, but, as mentioned above, this was achieved with
primitive technology over two thousand years ago in Europe,
Asia, and Africa. Why not in North America?
|An interesting and certainly
exasperating aspect of this project is the fact that
Dave Gillilan repeatedly asked Ohio's state archaeologists
to at least take a look at his material as
he was removing it from where it appeared. (He had no
choice but to remove it, as he was committed to finishing and
selling the house beneath which the artifacts had appeared;
this was an urgent matter of financial necessity.) His
pleas were ignored. Upon being shown photographs
of the material taken by this author after its removal, the
state archaeologists declared it to be typical of a nineteenth
century landfill (trash dump), and of no archaeological
interest. It was not meaningful to them that the
artifacts included points and blades, groundstone tools, half
a bannerstone, and pottery fragments, all professionally
assessed as being from around 2000 years BP, and absolutely
nothing definitively identifiable as culturally of the
historical era. (There is no record of there ever having
been a landfill at this location, and in laying utility lines
for the property, Dave had dug up thousands of cubic feet of
ground, seeing nothing suggesting a trash dump.)
In October 2006, Dave and
this author, at their own expense, engaged the services of
a professional geomorphologist recommended by the Ohio
Historical Society to assess the stratigraphy immediately
adjacent to the find area.
The geomorphologist's report
the exception of the uppermost 20-cm thick plow zone, there is
no evidence of prehistoric or historic disturbance of the
sediments revealed in the soil profile of the trench."
The archaeologists' response to this: "There must
be a landfill there somewhere. Just keep looking for
it." Apparently this is their understanding of scientific
inquiry - start with an a priori conclusion
and work back through the evidence for as long as is necessary
to make this support the conclusion. (It is worth noting
that these are the same purported experts that contemptuously dismissed
as a geofact the now well known and professionally verified sandstone
turtle head sculpture unearthed by Dirk Morgan near the
Fort Ancient site.) Needless to say,
there is a bit of a commun- ication problem here, given this
author's own approach of carefully assessing all the available
evidence, however unexpected or anomalous, and working from
this to hypotheses that can be either proved or disproved on
their own merits.
