Details include: a 5x5 ft. “Unit” under excavation as seen from directly overhead.  White level lines for control are strung around three sides and several are still strung out to corner pedestals of former Units, now completely removed down to limestone bedrock.  A small sliding line level can be seen on the line around the Unit in question, and it is being step-excavated with trowel, dustpan and whiskbroom – all clearly visible in the picture.  Nearby stands a filled spoil bucket –(for scale, a toothpaste tube cap) - waiting for someone to carry it to the sifter station and rocker-wash the contents.  At extreme upper left, is a small nested clutch of tiny shells – emulating the Leucine clam shells often found “nested” together in some solution pits – and often associated with just one or two potsherds among them.  Whether these were deliberate deposits, or the work of chance and weather perhaps after site abandonment, has not been further stated.
