Today we finished off C1 - changed loci mostly because it was level, but also b/c the topsoil and first layer of wash has been removed. In C2, we continued to go down looking for walls. We definitely have a stump of Wall B4 in the SE corner, but it does not extend very far into the trench and we can't find a connecting wall for it. Maybe it is deeper - although it looks like it may be in the baulk once again. Drew the west section of NT01A with Armine in the afternoon.
