Spent the day laying out a new trench (06, 2 x 2) with Adam on a terrace to the east of T05b and excavating topsoil (locus 01). In operation T05b, closed locus 6, the floor, and opened locus 7, to mark the emergence of a cluster of rocks in the west section of that trench. The matrix of locus 7 was largely the same as locus 6 -- packed clay littered with specs of charcoal. Based on pottery, appears to be an Iron 3 deposit.
