Day 2
|
The Southwest Bastion |
Today was the second day of excavation at
Fort Tombecbe. As many of you reading this blog know, we are currently
excavating the palisade wall and the bakery area in the southwest bastion of
the French Fort. Today we split up into two teams, Team Bakery and Team
Palisade. Team Palisade opened two brand new excavation units and continued
work on the palisade wall. Team Bakery opened up two and a half new excavation
units and continued work on a feature previously documented.
During the many hours that I was removing dirt, I realized
three very important facts.
1)Roots are the bane of my existence.

Menacing I know |
2) There
is more dirt than you will ever imagine coming from just a few centimeters
depth.
3) If you need anything identified, lick it. Or ask Jean.
Despite the first two distressing points, today was a very
informative day as to learning how to excavate.
First, if there is grass growing on top of a unit, take the clippers and
clip them. Do not pull them up because this could ruin the context beneath.
Second, when pulling back the dirt, only take back a little bit at a time. When
you have finally removed the hummus and organic material of the top layer, then
you take a sample and assign it a color, texture, and note any disturbances in
the soil.

Munsell or Munsell it's all the same. |
To assign color, as everybody sees colors differently, Dr.
Albert Munsell created a color system based on value, hue, and chroma. It’s
called the Munsell Color System! Anyway, take a sample and match up the colors
and that is the color of your soil. We usually refer to a page called 10YR as
that matches up most of the soil located at Fort Tombecbe.
Texture is separated into four categories: sand, silt, clay,
and loam. Sand is gritty (hint: think beach sand). Silt is powdery like flour.
Clay is sticky and can form an inch thick ribbon. Loam is a combination of
these three categories. The soil we were working with today over at Team Bakery
was actually a loamy clay like texture. It came up in clumps and is not very
fun to work with.
Once the soil is assigned its traits, then comes the serious
digging. Everything is put into buckets that are assigned a provenience, and
with provenience comes paper work. Provenience includes the site number (ISu7),
the area excavated (Wall Area/Bakery), the Unit number (e.g. 24,25, 17), the
zone number (the southwest bastion), digger’s initials, the date, and the Field Specimen number (mine was 423).
During the digging, Team Palisade (and Brian) found some
nice artifacts and features including a whole brick placed within the palisade
wall. Great job, guys!
Team Bakery, (Jean Louise, BJ, James/Boone, and me of course) mapped a feature that
needed to be redone and we also found two pieces of brick, a bone, tree roots, worms,
centipedes, and snails. We also had our
dreams and hopes crushed by nature. We found a square “gaming piece” (chalk)
and three pieces of brick (actually mineral inclusions). Hopefully we will learn more as we go deeper,.
