Geography comments: "in southern Camels Back Ridge" (basis of coordinate)
there is a single radiocarbon date of 9560 +/- 40 B.P. at the top of Stratum I, although the authors think the "recovered materials may date to ca. 12,000 14C yr B.P." (presumed to be uncalibrated because errors are symmetrically distributed)
