This week’s update on the progress of excavation group five comes courtesy of ANTH60a student, David Giliotti. David is a Brandeis University undergraduate student majoring in Computer Science and Anthropology.
Like last week, our dig began with very undesirably wet weather. However, we persevered despite the conditions and ended up getting a substantial amount of digging done. Today began the opening of layer D. At a depth of about 34.5 cm the orange sand of the layer was very prevalent. It was a nice change of pace to dig through sand as it was much softer than the rough dirt we had previously been digging up. We were filling buckets up faster than we could sift. Interestingly enough, the sand also made way for a slew of moderately sized rocks. Because of this, we estimated the gravel content of the layer to be about 20%.
Sadly, at this point, we were deep enough to not expect any notable finds. However, in order to truly close a unit we dig at least 50 cm without finding any new artifacts. At about 60 cm deep, we hit a new lighter version of sand that looked like it came straight from a beach. This made a lot of sense as our site is located adjacent to a river. At this point, we closed layer D and opened up layer E. After another 30 cm of digging through layer E (the biggest layer yet), we hit the 50 cm mark of finding no artifacts (at about 84.5 cm). Digging at this depth proved to be especially challenging because it was hard to reach almost a meter in while making sure the walls didn’t collapse from our body weight. It should be noted that there were slight patches of dirt near roots that showed a blackish color. However, we do not believe that this represents a new layer. As such, during next week’s dig we plan to close the layer and finish up the unit.
In short, it was a very eventful day of digging, but sadly no artifacts were found.
