Today we took down AC2 locus 3 (dark brown soil on the east side of the trench) in a series of passes, simultaneously working to define the linear stone feature (locus 5). Locus 5 is showing more, lower courses of stone in some places, and is proving to be made up of stones of medium size as well as chunks of eroded concrete.the lower courses seem to prevail in the southern and northern areas, i'm not sure whats going on in the north-central part of the feature. Locus 3 gave way to a general level of stones and concrete, the top of which we cleaned and photographed and which i am calling Locus 6 (Locus 6 in AC1 is also a stone and concrete layer, incidentally)-- in the south end of the trench we pulled up a piece of worked masonry with a partial zigzag pattern carved on the end of it.
In the afternoon we moved over to AC1 and started taking down locus 6, the stone and cement collapse layer with associated sandy chunky soil. I removed the upper stones in this locus and cleaned to the level they were resting on them: we revealed a layer of interlocking large masonry stones, which seem to have fallen in tandem on a single surface. Associated with them are a number of large pieces of worked masonry. i cleaned this context and photographed it.
