Accumulation of black sediment N of walls 3095 and 3030. Excavated as one SU. Section shows four layers: a black lense covering a thick brown layer with orange inclusions, a layer of lose black soil, and the final compact brown layer with orange inclusions. Within the layer patches of black soil appeared throughout. These layers may be associated with leveling activities or dumps meant to compensate for the sharp drop in bedrock elevation in the S part of Room 1. Also possibly related with black batches found throughout Rooms 1 & 2
