Abstract

An average uranium-series age of 102,000 ± 14,000 yr for bones from Louviers Alluvium, near Denver, Colorado, is compatible with the inferred geologic age of from 120,000 to 150,000 yr. A uranium-series date of about 190,000 yr for a bone from Slocum Alluvium, near Canon City, Colorado, is consistent with the inferred geologic age of from 150,000 to 260,000 yr. Age determinations for the Broadway Alluvium are inconsistent but its geologic age is considered to be 15,000 to 30,000 yr BP.
