Context
Charcoal from burned log found 16 cm bmgs. The same excavation unit had burned adobe chunks at 10 cm bmgs. No assoc. artifacts noted. Could be from a natural fire. NOTE: Author converted the Beta date (Libby half life) to the Cambridge half life to derive a date of 1823 +/- 50. For consistency, the reader should use the Libby half life that I have used. F1, stain.
