My first day supervising excavations this year. We're continuing in T05b, locus 4, brown silty sand. The wall at the eastern side of the trench is already 3 courses. Expecting to come upon a floor soon. Collected a charcoal sample from locus 4. The trench was getting deep, so we built a staircase in the southern baulk (locus 5). Half day due to rain.
