Environment
Lithology: siltstone
Taphonomic context: human accumulation, midden, settlement
Archaeology: bone tools, stone tools
Habitat comments: "a Milling Stone occupation" including numerous tools was "in the basal levels of the deposit (ca. 170-250 cm."), which consisted of a "midden" within a "soil"
"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"
