The morning was spent opening a new operation, WSDB. The justification for this is detailed in the place form for locus 1. Briefly restated, I was targeting a room that was small (akin to WSH and WSG) and adjacent to WSDA, so as to expose possible traffic flows. We spent the day removing the sod (locus 1) and then getting a start on the wash deposit beneath--a \"black\", clean silt. Medium material densities so far, but only getting started in locus 2. Some setbacks with equipment today--several new shovels broke. But we managed.
