Our work in Room 28 is winding down. We reached the level George Pepper and
Richard Wetherill reached, found features that they did not expose, reopened
areas that they dug beneath the floor, and took a small portion of the room to
sterile soil. We have spent the
last week mostly recording the features, mapping, and taking samples. There remain two beams in place that we
still need to pull, more pollen samples to take, and a couple of pieces of
ground stone incorporated into the architecture that we will also remove. What did we find? Pepper and Wetherill took many
wonderful photographs and drew a schematic of the room, but they did not provide
a complete description of the room and apparently did not uncover all of the
walls and features. We found and
documented 27 postholes. There
probably were more that had been destroyed by their excavations. We found a small thermal feature and
ashpits. We found a large pit dug
by Wetherill and Pepper just outside Room 32, apparently to enlarge the space
for working in that room. We
marveled that none of their crew was injured by falling walls (that we know
of), when it took five sets of scaffolds to hold the walls in place for our
excavations. The artifactual finds
will be described in the future.
Friday morning the student crew left Chaco and we began the
LiDAR mapping of Room 28. We
continued mapping Saturday with rooms around Room 28 for context. Dr. Wetherbee
Dorshow, President and Grand Poobah of Earth Analytic, Inc., Jed Frechette of
Lidar Guys, and Scott Dillon of the Division for Historic Preservation in
Vermont, collected over one-half billion data points that are accurate to less
than a centimeter. From these
data, they will create a 3-D model of the room and surrounding area.
At a going-away reception, Susan and Meredith, the
campground hosts, made an incredible replica of the excavation in CAKE, with
tiny cylinder jars and even a backdirt pile. This was an entirely different 3D model of the
excavation/room, and tasted better than the half billion data points. Our thanks to them for their kindness
and creativity! And GB’s ice cream
is the best version of chocolate ever consumed in Chaco.
Our crew did a lot of work in a short period of time (23
work days!) with good humor. As
with all archaeological projects, we developed jokes, songs, and language that
we all understood, but that folks outside the crew would probably find baffling
and not as funny as we did.
The Park particularly asked us to limit our discussion of what we were
finding—and in Chaco, where voices carry so far, to keep as quiet as possible. This was both to keep from altering the
Chaco experience by making noise and to avoid attracting vandalism. So we often spoke in code. The following list is for the crew, for the
record, and everyone else may want to skip reading:
