Environment
Lithology: claystone
Taphonomic context: human accumulation,midden,settlement
Archaeology: bone tools,stone tools
Habitat comments: "The upper layers... (0-80 cm.) consisted of a dark midden with a high clay content and modest quantities of marine shell"
"both temporal components yielded diverse arrays of ground stone (handstones, milling slabs, mortars, pestles, and pitted stones), bone awls, projectile points, scrapers, and debitage that reflect a wide range of domestic ands ubsistence activities. CA-SLO-585 clearly functioned as a residential base"
