Cleaned bedrock in ELT1 which took awhile due to last night's rain. Also finished ELT2 after continuing down in sterile yellow clay layer that Pavel says represents bedrock. After lunch took final photos of both trenches. Drew west profile of ELT2.
Started two new trenches SLT1 and 2, two possible structures near southern base of fortress. SLT 1 is a 2.5x2.5m trench and SLT2 is a 2x2 trench west of SLT1. Recovered small whetstone fragment in SLT1 topsoil about 10-15cm below surface.
