Geography comments: "approximately 28 miles northeast of the town of Rock Springs.... about 0.5 miles east of... Paint Creek, and approximately 3.8 miles due east of the Rigsby Triangulation Station" (coordinate estimated from map based on the location of Telegraph, which is 31.4 miles northeast of Rock Springs)
"A carbon 14 determination" of 3, 826 +/- 208 years BP is based on charcoal from beneath one of the skulls in layer B (presumed to be uncalibrated because the error is symmetrically distributed)

Environment
Lithology: mudstone

Taphonomic context: bird accumulation, cave, fluvial deposit

Habitat comments: a "sinkhole"
layer C is a "fine-grained, brown, clay-like material rich in carbonate grit" and layer B is "composed largely of limestone boulders and cobbles with some institial mud matrix"

Sampling methods: quarry, screenwash

Sample size: 983 specimens
