from a horizon yielding Agate Basin cultural complex artifacts
Pelton et al. (2017, Quat Res) provide a calibrated age estimate for the Agate Basin interval at Hell Gap of 11,750 BP, which is based on an age-depth model and apparently is driven by a conventional radiocarbon date of 10,520 +/- 100 BP for substratum E2
