A productive day. Many large rocks in locus 10 were split and removed by Sahag and company, locus 11 was closed, and locus 12 opened. Locus 12 occupies the W corner (3m from the NW edge, 2.5m from the SW edge) and possibly contains a feature. We'll see after the next pass.
Locus 11 revealed that part of the SW wall (about 9m from the W corner) might be structurally unsound and / or leaning against the wall fall which is particularly deep there. This is right at the edge of the area we're leaving alone for the time being (approximately the back (SE) third of the trench), so it might be complicated to deal with. Once the middle of the trench is free of rocks we'll see what the situation is.
