The perimeters of pastoral bases often have dense artifact scatters, including pottery fragments from a variety of time periods, however there was a relatively low frequency of high density lithic loci inside of pastoral bases. When all of the high density loci are considered, only 30 (23%) of the high density lithic loci were located in sites classified as "pastoral bases".

High density lithic loci in this region primarily consist of obsidian flakes and it appears that, despite being located off of the pastoral base sites, these high lithic concentrations still seem to be associated with early pastoral occupations. This inference is based on two aspects of these high density loci: (1) most of the pre-Series 5 projectile points are not obsidian, while most of the Series 5 points are obsidian, and therefore if point production was occurring they were probably making Series 5 points; (2) if merely flakes were being produced, such production was probably linked to pastoral butchering, and therefore the obsidian is again linked to the pastoral occupation of the area. Why, then, were the high concentrations located outside of the pastoral base areas as noted above? One possibility is that one may be seeing a site maintenance pattern where some lithic production is occurring offsite during pastoral herding so that the residential base is not littered with sharp flakes.
