Photographs and/or drawingsLithic Sourcing StudiesIt is critical to determine if the assemblages of tools and manufacturing by-products found at the siterepresents manufacture of locally available raw materials, or if some portion of those assemblagesrepresent manufacture (or tool use) of lithic materials which have been imported to the sites. Knowledgeof the kinds and artifact types represented in the non-local assemblage will play a critical role indetermining the kinds of lithic procurement activities conducted in the area, their roles in the exploitingsystems, and the degree of mobility or exchange.For the most part, local and regional lithic sourcing is limited. The identification of material sourceswould entail communicating with collectors, rock hounds, geologists, and ranchers. It would also requirefield work to verify data. One of the end results of lithic sourcing studies would be a materials collectionto be kept at each BLM field office (and other publicly accessible museums or universities) for use byresearchers and analysts. The following “Lithic Material Code Sheet” prepared by Regge Wiseman offersa beginning point for this kind of research. It is recommended that concerted program of lithic sourceidentification survey be undertaken to collect examples from these (and other) material types to compilecomparative collections.Obsidian sourcing has been successful using X-ray florescence (XRF). A select sample of obsidian fromwithin features, concentrations, and/or different site areas will be submitted for XRF analysis.The use of shortwave and longwave UV light on selected cherts (i.e., Edwards Plateau, San Andres) hasbeen successful in distinguishing Edwards Plateau cherts from look-a-likes and to aid in recognizingsubregional varieties within the San Andres gray cherts. Selected cherts, then, will undergo UV lightanalysis.6-35
