Ohio Archaeology, Part I: Summer Field School
Aired June 19, 2001
Ever have a hankering to follow in the footsteps of
Indiana Jones? Well, now you can. This week at sites around the state,
archaeologists are inviting the public to participate in some hands-on
activities that let you be the scientist. As part of Ohio Archaeology
Week, the Cleveland Museum of Natural History will hold an Archaeology
Day this Saturday, where you can watch a demonstration of flint-knapping
or learn to cast an ancient spear thrower called an atlatl. But for those
who crave the real, dirt-grubbing experience, there's a special opportunity
available through the museum every summer. That's a field school, where
anyone can join a team of excavators on an archaeological dig. 90.3's
Karen Schaefer brings us this report from a prehistoric village site in
Independence.

Karen SchaeferNo one knows the name of these
Native American settlers or where they went after they abandoned this
village perched high on the banks of the Cuyahoga River. But archaeologists
from the Cleveland Museum of Natural History are trying to learn more.
For the last two years, they've been excavating this 500-year-old village
site from the late Woodland period, trying to unlock secrets buried deep
in the earth. Directing the excavations is Dr. Brian Redmond, the museum's
curator of archaeology.
Brian RedmondWe do know the people who lived
here left the area by 1650. As to where they located their villages, there's
almost always a steep drop-off, a hillside or a cliff face that is on
one edge of the village, a kind of natural defense. So, by inference,
there was a lot of warfare at the time.
Deep
in the woods, archaeologists have opened three test squares on the
western side of the site, hoping to find the edge of the village.

KSBut as important as the work is to scientists,
it's even more exciting to the team of volunteer excavators who will dig
here for three weeks this June. Mary Lou MacGuire is a 7th grade earth
science and math teacher who's been a member of field school digs for
years. Today she's working in one of three two-meter excavation squares
mapping a circle of fire-cracked rock and charcoal debris that may once
have been a cooking fire.
Mary Lou MacGuireWe've mapped the major
rocks, basically kind of go at anything as large as my fist. And kind
of eyeball sketch the rest in as accurately as possible and adjusting
and taking a point every now and then to make sure we're right in there
with the ones we're eyeballing.

filled with trash. Levels and plumb bobs are used to measure depth
of finds.

KSUsing tape measures, a level, and a plumb
bob to record depth below the surface, other workers in the same square
are carefully noting the exact location of a scatter of darker soil stains.
They may be holes once filled with upright posts.
MLMThat's going to be our next task is to
take each one of those one at a time, section them down, cross-section
them so we can get a side view. And from the profile we can tell whether
they snake off in weird directions - those are rodent holes.
KSMore important to archaeologists than
individual finds are the spatial relationships between one artifact or
feature and another. MacGuire says if workers can uncover a pattern of
other post molds, they may be able to establish the edge of the village.
And that could help determine how many people once lived here. MacGuire
says she's developed a passion for the work.
In
the next square, excavators have uncovered a circle of fire-cracked
rocks on the ancient living floor, after removing about a foot of
surface soil.

MLMI consider myself an archaeology groupie,
yes. I've learned so much, I keep coming back for more. I think it makes
me a better teacher. I wasn't keen on science as a kid, so I thought it'd
be neat if I could find a way to get excited about it myself.
KSNot everyone here shares MacGuire's expertise.
In a neighboring test square, the Sauers, husband and wife, are digging
a former storage pit that later filled with trash. On the surface, the
outline of the pit is clearly visible as a line of darker soil. Six feet
down, Bruce Sauer is excavating a cross-section that exposes each layer
of debris.
Mrs. SauersThis is our first dig. It's really
something.
Mr. SauerIt makes me wish, if I'd been involved
in some of this as a youngster, it might have meant a career change for
me.
Each
shard is wrapped in foil to reduce contamination, then bagged and
labeled. In the lab, researchers will identify grit, thickness and
decoration.

KSAs each bucketful of dirt is lifted from
the pit, workers empty it onto a wire screen suspended from a tripod.
They shake the screen back and forth, letting smaller pieces of dirt drop
through the mesh. Then they carefully pick through what remains. Bits
of stone, pottery and charcoal are bagged for further study back at the
archaeology lab. Plant remains from this early farming site are found
using flotation, a technique where deposits are dumped into a bucket of
water. The lightweight plant materials float to the surface. It's hot,
dirty, often tedious work - until Bruce Sauer makes a find.
Sauer et al.Oh, you have pottery?
Yeah. Pieces.
Let me get you a brush so you can see what you're doing.
Yup, as Martha would say, I think we've found the Big Kahuna.
At
the archaeology lab at the Cleveland Museum of Natural History,
researchers were able to reassemble a similar cache of potshards
found at a site in Lorain County.

KSIt's the moment everyone's been waiting
for, when Sauer lifts a 500-year-old potsherd from the dirt. By the end
of the day, more than a dozen big pieces of pottery have been found, probably
all from the same large cooking pot. And that's not all that was discovered
today.
Archaeologist et al.Any questions? We
found a feature, our group, feature nine. You guys sectioning post molds,
you get any real posts?
About 7 or 8.
Out of how many?
20-some...
KSYet despite the rich remains at this site,
archaeologists will close the dig after this summer. Just 1% of the village
will be excavated now, but that's enough to tell researchers a lot about
this settlement, one of several that once lined the Cuyahoga River. That
will also leave plenty of the past for future archaeologists to uncover,
both amateur and professional alike. In Independence, I'm Karen Schaefer,
