Before starting new trenches today we did some more cleaning and measuring in WSC2 and WSE. We'll see what Adam says tomorrow about the two. It's possible we'll need to come back to these. Started a new trench in K. It's 6 by 2 and juts out from the far wall into the room. Was hard to determine the exterior of the wall. The second new trench is a 4 by 3 in room M. The trench comes out from the wall to the middle of the room. Decided to avoid the confusing architecture of thc corner and instead try to get to the middle of a room for the first time.
