- Comments
- EdRk-4, Nesikep Creek: Test pits suggest that the site measures about 100 x 70 m. Part of the site has been deflated by wind erosion, and small mounds of sand surround isolated clumps of sagebrush. Dunes reach considerable depths in the south and east (Sanger 1970: 13). Zone VII, the deepest zone, yielded GX-408, one of the earliest dates in the Lochnore-Nesikep sequence. Lacking adequate charcoal, bone was used for the date (see Sanger 1970: 104 regarding his considerations of bone dates). Sanger marshalls stratigraphic and theoretical reasons to conclude that GX-408 is somewhat too recent. He concludes that Zone VII is at least 6000 years old, perhaps closer to 7000 years. The argument is related to Sanger's opinions concerning typological comparisons with Lehman site Zone II (I-2367). A charcoal sample (M-1510, CMC-8) was submitted but declared too small to date.
