Environment
Lithology: not described
Taphonomic context: human accumulation,midden,settlement
Archaeology: bone tools,burials,ceramics,hearths,stone tools
Habitat comments: a 4 m mound above natural alluvium covering about 1.5 ha
"most of the stratigraphy" resulted from addition of alluvial soil to "occupation floors"
soil concretions indicate "intensive cooking" and many of the radiocarbon dates are on charcoal
there are numerous potsherds, many more complete pottery pieces, stone tools, clay pellets used for hunting, shell beads, a bone fishhook, and seven burials
