Document Summary
For first paper stuff from today plus film tomorrow plus everything before this. Have broken mammoth, yana rhs, and swan point stuff for sure. The yana site is before bluefish caves and is from the western edge of western. Bluefish caves in east beringia, new dates range from 24-12,000 bp, may not have stone tools but has the wear marks from the stone tools on the bones, proving human occupation/interaction. The calibration for these are done with oxygen-isotope calibration which is done via depositions in specific layers beneath the ocean floor, but is not as tight as when done with dendrochronology, but doesn"t mean they"re wrong. Not a long occupation, instead a site that has been reoccupied multiple times as people come back for various short-term occupations. Oldest artifact from 24-23,000 bp dates to within or at least really close to the glacial maximum. An idea which comes from the genetic data.
