† Midden numbers occasionally overlap among sites but are distinct within sites. Numbers were based on aluminum tags nailed into the bedrock at collecting sites. Repetition of midden numbers within sites results from multiple dating (usually one conventional beta-count and one accelerator mass spectrometry (AMS) date) from the same midden.
‡ Ages based on conversion to calendar-years using Method A (ranges with intercepts) from Intcal98 (Stuiver and Reimer 1993, Stuiver et al. 1998) for all dates <20,000 14C yr BP. Age estimates include the median intercept and (in parentheses) minimum and maximum ages based on 2 standard errors from minimum and maximum intercepts. Radiocarbon ages greater than 20,000 14C yr BP were not converted.
§ All conventional beta-decay age estimates were based on Neotoma fecal pellets. AMS age estimates were obtained for paleobotanical material or fecal pellets as indicated.
|| "P" denotes occurrence of macrofossils of Utah juniper in the midden, "A" denotes absence from the midden.
