Abstract

The analysis here of 49 artifacts (48 obsidian) from two sites in southeastern New Mexico exhibits an obsidian provenance assemblage entirely from Jemez Mountains sources, one of which (Cerro Toledo Rhyolite, 79.2%) was most likely procured from Rio Grande Quaternary alluvium. Valles Rhyolite (Cerro del Medio) at 20.8% of total was probably not procured from Rio Grande Quaternary alluvium, but the primary source proper, according to available research (Church 2000; Shackley 2012).
