Working our way down to the occupation zone! (Photo Credit: Austin George) |
Hello again! This is
Connor and over the past few days my unit went through an exciting and
important time in the excavating process. We were continuing to excavate our
one by one meter unit down to 50cm when we made some intriguing finds. At this
level we expected to break through the plow zone and begin to excavate the
occupation zone, so we would see 18th century artifacts lying as
they were left over 200 years ago. One of the things that we started to notice
was that a bone midden, which is essentially a trash pit, in a unit from last
year appears to continue into the unit that Nolan and I had dug ourselves. Not
only that, but were also surprised by a large stone that is resting just within
the occupation zone and is aligned diagonally across our units with another
possible structural stone in the two by one unit to our east. With a little
more observation we had begun to see that the frequency of bones in the south
of our two units was drastically higher than in the north of them. Similarly
the line that the two stones form seems to be correlated with the discrepancy
in bone distribution. More bones are found south of the rocks and relatively
few to the north of the rocks. This is really exciting for us because our
original one by one unit was placed in anticipation of intercepting the south
wall of a French colonial home and our working hypothesis is that this may be
it and the midden is where refuse from the house was tossed out.

With having reached our occupation zone and knowing that
we have artifacts that are in their original orientation, we began to prepare
the unit to be photographed. This entailed clean scraping the walls and floor
of the unit to ensure the soils are clear and easily distinguishable, helping
us to document the stratigraphy for future reference. The next step was to
place the site and unit information on sign board along with a north facing
arrow, with a scale in centimeters, into the unit without obstructing any
artifacts and taking several pictures from above. After both color and black
and white photos were taken, we began to create a one by one meter map of the
unit with all objects in the unit represented to scale. This is a most critical
time for excavating the unit, as every object is lying where it was when the
fort was occupied and if this information is not recorded then it will be
destroyed if we excavate any further. Each layer of soil helps us better
understand how artifacts are in relation to each other and that not only helps
archaeologists but everyone understand the site better. So with the preliminary
documentation of the occupation zone complete and with a bit of luck, Nolan and
I may find what we set out looking for. Stay
tuned!

This is very interesting. Do you know if the bone midden was created from people from the fort or was there Native Americans near the area that might have created the bone midden? I am also
curious, are measurements of the fort in feet? I know historic buildings were mapped in feet, so archaeologists use feet to compare historic maps to what was found.
