Work began by working in both Locus 3 and Locus 4  First  a light pick pass was made of the entirety of Locus 4   avoiding all rocks Soil is olive brown in color with some limestone inclusions and charcoal fragments and is fairly claylike in texture  some patches of gray  chalky soil are scattered throughout the locus  especially around the slightly curving rock feature  although there are noticeably fewer patches than in Locus 3
