After further study and identification of this area as a quarry, it appears that this is one of a series of cuts into the bedrock associated with quarry machinery.
Circular cut in bedrock. Possibly a garbage pit. Similar to others in western central part of Area A. The presence of anthropogenic materials within SU32 fill may suggest a garbage pit. The lack of charcoal or ash precludes any hypothesis that it might be a cremation burial. Its size may exclude it from being a post hole.
