PLATE 17 Tule Springs Locality. Southwestern Nevada The Tule Springs Locality (PL. 17) is of prime importance because the presence of ash and charcoal has permitted the Uni- versity of Chicago Institute of Nuclear Studies to date Man's presence here at "more than 23,800 years" (Libby, Willard E., 1954). Buried under 10 to 20 feet of lake or pond deposits, the ash and charcoal are combined with broken bones of camels, bison, horses and mammoths—all extinct Pleistocene fauna. Many of the bones have been broken and split for marrow, many are charred. There are a few bone tools and some closely associated stone tools (PL. 19). The high-backed plano-convex scraper is predominant among the implements thus far recovered. As yet, no weapon points have been found. However, excavations are incomplete and the chronological position of this site in the tech- nical evolution of the lithic industries is tentative. The Texas Street Locality (Carter, C, 1954) derives its im- portance from the fact that the crude cores and flakes and fire- broken rocks are buried beneath 50-90 feet of valley fill wdth a well-developed soil profile—a fact which suggests Man's presence either late in Third Interglacial or very early Wisconsin Inter- 67
