characterized by mobile
hunters and gathers.
PaleoIndians hunted
caribou, and actively
scavenged mastodon.
They made stylistically
distinctive spear points.
Some of their
occupations are found

12. The Woodland period begins variously around
2000 to 2500 years ago across the Great Lakes
It was initially defined on the basis of ceramic
technology, and divided into three subperiods
Woodland peoples domesticated indigenous
seed plants as well as tropical newcomers such
as squash and corn (maize)
Many village sites are found in coastal zones due
to the moderating lake effects of the Great Lakes

43. Procedures for GeoProbeTM OSL Sampling
Step 1: Once a sample location has been selected
on a larger site, position GeoProbeTM and take visible
solid core to the appropriate stratigraphic depth.
Photo at left is Bill Monaghan coring at Winter site.
Step 2: Assess stratigraphy
within the core. Ascertain
whether OSL sample is appro-
priate, and from what depth
within the stratigraphic section.
Photo at left is from Winter site.
(Photos by W. A. Lovis; used with
permission)
Step 3: Properly record stratigraphy in terms of
standard criterion such as color, texture, grain
size, organic content. Again determine at what
depth the OSL sample should be taken. Photo
at right is at Ekdahl-Goudreau/Seul Choix site.
44. Procedures for GeoProbeTM OSL Sampling
Step 4: Repeat the coring procedure at least once, and
possibly twice. It is necessary to obtain a control, or
Gamma, sample, which does not need to be light tight.
More importantly it is necessary to obtain a light tight,
sealed sample for OSL dating. Thus, the core tube is
blackened, and covered with duct tape. It is “blind”,
which is why depth assessment is critical since the
sealed sample tube is cut at the appropriate location.
Photo at left is the Ekdahl-Goudreau/Seul Choix site.
Step 5: Appropriately field archive all
samples, both OSL, and Gamma, as
well as preserved solid cores with
visible stratigraphy. Document UTM
and Lat/Long locations of cores using
reasonably accurate GPS device. As
necessary, appropriate, or required,
backfill core holes with BentoniteTM clay
to prohibit contaminant seepage into
groundwater. Photo at left shows solid
cores from Winter site.

49. The Winter Site, Delta County, MI
The Winter site was AMS
dated using carbonized
food residues adhering
to the interiors of ceramic
vessels. The basal
occupation horizon was
dated from two sherds, a
Plain sherd, and a North
Bay Corded sherd. The
middle/upper horizon was
dated from a single sherd
of Vertical Corded pottery.
The dates on the lower
horizon are statistically
identical. The date on the
middle/upper horizon is
both earlier, and not
identical. This suggests
Photos by W. Lovis; that these stable horizons

The basal OSL date is
earlier than all of the AMS
(Graphic by G. Monaghan; used with permission) dates.
50. The Scott Point Site, Dated diagnostic ceramic rims from

MI
Mean Pooled Age
and an Oneota Shell tempered rim
producing statistically identical dates
Cal BP 865±28/AD 1085 with a mean pooled age of cal BP
865. This reveals that the last
stabilization of the site took place
ca. A.D. 1085.
The base of the deposits were dated
on the basis of a diagnostic
400 yrs Mackinac Ware rim producing an
age of cal AD 770. This date is
consistent with the known age of the
ware, and indicates that the basal
EXCAVATED deposits at 1.5 mbs
were stable ca. A.D. 700-800.

51. Based on our sample, there are very few
Nipissing age dunes, i.e. pre- 4000 B.P., and
they are relatively small.
There is a surge in dune growth frequency,
intensity, and size ca. 3200 to 2000 B.P.
Dune activation slows and reduces in intensity
between ca. 2000 and 1000 B.P.
Dunes again become more active from 1000 B.P.
to 700 B.P.

55. Three Holocene Lake Level Curves proposed
for Lakes Michigan and Huron
Basis of Lake-Level Curves:
Larsen (1985): 14C ages from beach ridges, mainly in
southern Lake Michigan.
Thompson et.al. (2004): sedimentology of sets of
recessional beaches within embayments.
Monaghan and Lovis (2005): 14C ages of beaches,
transgressions in mouth of rivers and archaeological
sites, mainly southern Lake Huron (Saginaw Bay).
Points of Agreement: three broad intervals
High water events 6-4 kya
Low water (or stable?) interval ca 4-2 kya
Fluctuating levels (alternating high/low) post-2 kya

63. Potential Human – Dune Landscape
Interactions North of the
Zone of Isostatic Rebound
Human occupation is normally BEHIND dune crests, most often in a hollow or
the swale behind the foredune
Occupation surfaces most likely are not stable, and they do not display the
normal signatures of soil formation. This suggests they may be induced as the
product of human enhancement rather than natural pedogenic processes. They
are anthropogenic horizons, and may not be formal paleosols.
Organic enhancement occurs with the introduction of charcoal, oils and fats,
charred bone, and organic debris. This organic enhancement fosters rapid
vegetative growth in protected and occupied swales and hollows.
Human foot traffic over lakeward positioned dune crests results in local level
mobilization of the sand supply. Eolian activity deposits a veneer of inorganic
sands of varying depth over the organic occupation surface. This process may
occur once, resulting in burial of a single occupation, or cyclically resulting in
stratification.
