I spent the morning mapping while Adam supervised operation 06. He created locus 2 along the eastern half of the trench. Then locus 03 for the western half. Each locus is a 2 x 1. Both loci were extremely rocky. Hardly enough space to excavate and assess what rocks could be removed. So I expanded the trench one meter to the west, turning it into a 3 x 2. The sod of the extension is locus 04, a 2 x 1. The first wash level beneath the sod is locus 05. Today I also continued to work in locus 07 of T05b--the highly packed clay floor or sub-floor surface. Collected charcoal sample.
