Two radiocarbon dates were reported by Goodwin and Reynolds (1989). A date of 590 ± 120 yr. BP from the level was considered to be derived from reworked charcoal, and was rejected. A more reliable date of 9830 ± 150 yr. BP was reported by Goodwin and Reynolds (1989) who indicated that it was taken on charcoal re- covered from the foot level (approximately 6 m above the base of the se- quence) and that the date was provided by Beta Analytic (Beta-2155). The same information was provided by Roth and Reynolds (1990), but they attributed the date to a 1985 Hn ///7\' communication from Andrei Sarna-Wojcicki to R. E. Reynolds. The 9830 ± 150 yr. BP age also was reported by Reynolds et al. (1991a) but was said to be derived from the foot level; in a separate paper in the same volume, Force (1991) gave the age and depth as 8950 ± 160 yr. BP from a depth of 7 m. An age of 9850 ± 160 yr. BP was given by Jefferson (1991). Thus, all authors report only one accepted radiocarbon date, and that accepted date is from sediments between 6 and 7 m above the base of the fossiliferous excavation (between and foot levels; see below). At our request, Eric Scott of the San Bernardino County Museum recently located the original documentation for the radiocarbon dates. Beta Analytic sam- ple 2155 yielded a corrected radiocarbon age of 9830 ± 150 yr. BP. A handwritten note in R. E. Reynolds' handwriting on a photocopy of the Beta report reads "at a depth of ft. in sediments within the cave/' The cover letter accompanying the report indicates that
