Finally hit bedrock at west end of T02b at 4m below T02 datum. It appears that a channel was carved into the bedrock to accomodate the wall entering T02b from T02 to the south. We uncovered a couple more stones from the wall resting on top of the bedrock. The part of wall in this trench is locus 8. Locus 7 is the soil surrounding the lowest course of the wall, as it became a bit tanner and loamier but was gravelly to the last. Carbon sample collected at this locus at 390cm below T02 datum.
Removed topsoil from T02c expansion. Topsoil is locus 15 and below that is 16 following sequence of T02c loci. Trying to open western area overlying locus 12 E.B. vessel to get a better photo of it before removing it.
