Geography comments: "at an inland valley in eastern Poway... on a south-facing slope within Beeler Canyon" (coordinate based on Poway)
"The lower layers of the pit feature had a mean radiocarbon date of 5,300 B.P., while the hearth feature had a mean date of 2,800 B.P."
Feature F dates were 5,210 +/- 80 B.P. at "40 to 50 cm." and 5,370 +/- 70 B.P. at "80 to 90 cm." (presumed to be uncalibrated because errors are symmetrically distributed)
