- Comments
- DlPo-20, Gap: Four archaeological living floors were found in the Ah horizons of buried palaeosols. The uppermost, Floor 1, yielded bison and canid bones but has not been dated and lacks culturally diagnostic artifacts. A sample of volcanic ash between Floors 2 and 3 was identified by J.A. Westgate as Mazama tephra. Of two dates on Floor 4, GSC-1158 is considered the better determination.
