The analysis here of 23 obsidian artifacts from Mesa Grande (AZ U:9:25 ASM), central Arizona displays a typical Classic Period Hohokam obsidian artifact assemblage (Table 1 and Figure 1; Mills et al. 2013; Shackley 2005). The assemblage is completely dominated by SonoranDesert sources including Sauceda Mountains and Tank Mountains in western Arizona, and Los Vidrios in northern Sonora (Shackley 1988, 1989, 1991, 1995, 2005).
