May 31: Expect the Unexpected, by Bronwyn Schell
When
I told my friends that I was going to be working on an archaeological
dig this summer, one of them immediately asked, “What could you possibly
be digging for?” She seemed to be under the
impression, as I’ve found a lot of people are, that all artifacts and
discoveries one reads about in magazines or sees in museums or on TV are
found as they are, whole and complete, either in caves or churches, or
perhaps in temples out in the jungle, a la
Indiana Jones. While the truth may appear far less glamorous, and is
indeed much more work, it is also much more important scientifically,
and I’d argue, much more interesting!
Since
our dig has only just begun, finds are still fairly small, few, and far
between. However, that does not give us an excuse to be anything less
than exact in our work! Having done initial
survey out in the field across the narrow access road from our sites,
we moved on to the job of choosing our plots, clearing the ground, and
laying out our squares for excavating. This takes more than it sounds,
involving several people, a machete, a weed-wacker,
several shovels, and hours of work.
Now
that our plots are exactly laid out and marked, we began digging. After
clearing the initial weed-filled uneven sod, we find the highest corner
of our plot to mark as the ‘datum’, the location
from which the depths of all other points are measured. The goal is to
dig down in even, 10cm layers, so that the location of all finds and
points of interest can be accurately recorded in our field journals.
Even with two people working on each plot, work
is fairly slow going. If you’re trying to make a 2 meter square plot
exactly 10cm deep at all points, you can’t just dig in with a shovel! It
takes us at least a day to go down a layer, measuring constantly and
digging carefully and often by hand, trying to
remove intruding roots without disturbing the layer beneath. The layer a
find is discovered in can tell us what time the artifact ended up in
the ground, because objects further down are usually older than those deposited
on top. Once you reach the bottom of a layer,
it is time for celebration!
It’s
not as simple as just digging a hole, though. Even working with trowels
and by hand, plenty of valuable artifacts slip
through in the removed dirt. To make sure we don’t miss a single thing,
we first save every single shovel and handful of dirt, in buckets, on a
tarp, or in a wheelbarrow, and first sift it all through a 1/4 inch
screen by hand, removing larger roots and rocks
and checking for medium sized artifacts.
After
this, we’re still not done with the dirt! We save it in the wheelbarrows and
buckets until we have collected a decent amount,
then we take it down closer to the handily located river, where a large
hose and a pump bring up a steady, pressurized stream of water. In a
process called ‘water screening’, we carefully put each shovelful of
dirt through a second
windowmesh screen on sawhorses, letting the loose dirt run through and keeping anything
that doesn’t filter out. We put whatever is left in the screen in labeled bags, to be carefully hand-checked later in the lab.
Although
water screening is a very necessary part of archaeological excavation,
sometimes it’s a little difficult. You have to be careful, or you’ll
look like you’ve just gone in swimming!
When
not digging, eating, or sleeping, we go on field trips to sites of
cultural relevance and importance. For example, this week we went to
Cherokee, North Carolina to visit the Museum of the Cherokee Indian and
a living history park, Oconaluftee Village, to attain a better idea of the origin, history,
importance, and creation of the artifacts we are looking for and
researching.
Of course, occasionally we run into things we didn’t expect!
May 30: Signs of Life, by Nolan Russert
And so it began, another beautiful day in the Tennessee backcountry
at archeological site 40WG11. The temperature has been fairly mild for
late May, but today was one of the warmest we have had so far. The day
began with each team continuing to dig further in the soil hopefully to
uncover more artifacts.
Most teams were on their second and third levels, which is approximately 20-30cm below the present-day surface. All of the excavation pits are located on the north and northeast side of the cornfield, not far from the swift-moving Nolichucky River. The backdirt piles began to accumulate as we reomoved more and more earth. The main process that occurred today after removing all of the soil was water screening. The soil is put into a windowscreen mesh, and a water pump pulls water from the river to wash the soil. The soil is placed in the screen and through the process of continual water movement and the students' pushing it through with their hands, the loose soil is washed away, leaving behind artifacts caught in the screen. Today, we discovered many pottery sherds. As we dig deeper and continue to water screen hopefully more artifacts are found to give us further knowledge of Spanish contact in east Tennessee!

May 22: You Got to Flag ‘em to Bag ‘em, by Daniel Scott
After an evening filled with rain we arrived at our new
field site with childlike enthusiasm. The owner of the field had just recently
plowed and planted this season’s corn making our systematic survey easier – as
the recently plowed ground clearly exposed ceramic sherds, lithics, bone,
shells, and fire cracked rock. With conditions right we spaced ourselves –
three corn rows dividing each individual – and began the process of slowly
walking North East through field marking the beginning and ending of “hot spots”
(which provide invaluable information as to the manner in which the town was
organized while also guiding us to the best location where we might place our
units and begin excavation). The previously mentioned surveying conditions
along with the relatively flat field allowed us to locate, identify, and
finally flag artifacts with ease, with the only hiccup in the day coming when
all the flags were expended.
Upon the completion of the flagging process – the following
day – the epicenter of the site revealed itself to be the most level ground on
very east of the field, nearest to the Nolichucky River – a common location as discovered
through previous field projects in the region – while smaller scatters of artifacts
were found outside this main concentration.
Once the flagging process was completed we began to collect
the artifacts by way of dog leashes. This method is executed by placing one’s
self in a group of flags and collecting everything within a five meter radius
of their center – we began at the south western tip working our way across the
field, avoiding isolated finds as often as possible. The center of each dog
leash circle was given a designated number, flagged, and plotted on a map
sketch of the area in order to keep the integrity of the town’s organization.
The vast area along with the large amount of findings prohibit a swift
completion of the gathering of all artifacts. Scenarios such as these are often
conducive to looters, however, our daily presence at the site along with the benefit
of its location on private property has allowed us to avoid becoming another
chapter in the long book of looted archaeological sites.
Prior to the onset of the Iraq war in 2003 archeologists in
the area and throughout the Middle East were brought home without the ability
to clean up or finish that season’s work. Martin Gottlieb’s article in the New York Times on June 12, 2003 quoted
the University of Chicago Dr. Gibson as he described the aftermath of the
looting of several active archaeological sites as a “devastated landscape” which
resembled “Swiss cheese” due to the deep holes dug by looters. This example is
just one of the many challenges that archaeologists face during a successful
and prolonged dig. [1]

May 27: A little work, a little celebrating on Memorial Day
Our very ambitious plans for research goals this summer do not allow for much time off. We started Monday morning bright and early with more systematic survey work at 40WG11.
After the initial survey of the fields completed last week, we began systematic collections of the artifacts visible on the surface. The locations of these collections will be plotted on the site map and the artifacts will be analyzed to look for patterning in the number and kind of artifacts in different sections of the settlement.
Towards the end of the day, we also selected the location of excavation units. The excavations are located in a vulnerable area of the site, where the Nolichucky River has flooded sometime in the distant past and washed away an unknown amount of the settlement. The units are located near this area that has the potential to be further damaged by river flooding.
After this very busy day, we got together for a barbeque. The Field Director, Beau Carroll, was also the master of the grill and campfire:
We enjoyed a delicious dinner together and were glad to have a little time to reflect upon the service, sacrifice, and commitment of all those who have served our country.
