A sample of 117 Snake Valley series shards from southwestern Utah was subjected to Instrumental Neutron Activation Analysis (INAA). INAA was successful in identifying seven compositional groups, each of which is thought to represent a discrete manufacturing locus. One compositional group was identified in each of the site samples. Because the project sites are spread along a 221-kilometer segment of the pipeline corridor, it is likely the Group 7 ceramics were distributed through trade. The occurrence of Snake Valley series pottery at East Fork Village, a project site situated outside the core area of Snake Valley series production, is also attributed to exchange.
