Environment
Lithology: sandstone
Taphonomic context: aeolian deposit,human accumulation
Archaeology: burials,ceramics,hearths,stone tools
Habitat comments: fine sand with a sandy-muddy texture
the deposit is aeolian and was laid down next to a small paleo-lagoon
the site is interpreted as a base camp and mortuary area, and features include burials, lithics, thermoaltered sediments, and ceramics
some small mammal remains feature heat alteration and cut marks
