Lithic assemblages from the Chang Tang region, Northern Tibet

Archaeological evidence from the Chang Tang reserve suggests that humans ma y have first colonized the Tibetan plateau during the late Pleistocene. Bla de, bladelet and microblade technologies are found as surface assemblages i n a variety of contexts above 4500m elevation. The lack of modern analogues for foraging populations in high-elevation environments brings about recon sideration of the diversity and organization of Pleistocene hunter-gather a daptations.
