7.31.06 Today we continued to clear the wash layer in WSC3. We cleaned the wall and have begun to make it look better. We also broke a number of the giant boulders in the middle of the room. Unfortunately, we have more giant boulders yet to break and also lots of dirt yet to move. We did reach a lighter, more clayey soil in the eastern quadrant of the room, though, which is encouraging. As soon as we have cleared more of the dark wash layer, I will make a new locus.
