Abstract

All the artifacts were produced from two of the sources in the Mule Creek Obsidian Complex, Mogollon-Datil volcanic province, western New Mexico (Antelope Creek and Mule Mountains), although obsidian from these sources are also available as secondary deposits in San Francisco and Gila River Quaternary alluvium in eastern Arizona (Shackley 1992. 1998; Shackley et al. 2018; Table 1, Figure 1, and cover image herein). The cortex on sample #12 fnmLA 187467 appears to be typical of the secondary deposit obsidian in Gila River alluvium (Shackley 1992,1998).
