It was a short day today because we were rained out at around 10:30. We spent the morning excavating the small locus 20 and then proceeding with another pass over locus 19, probably the last locus about bedrock (judging by the depth evident from the work in locus 14). Recovered a fragment of a groundstone from locus 20. Also continued working in locus 5 to clean the top of the wall (locus 13) and in locus 10.
