Pre-Classic Obsidian in the Northern Tucson Basin

Author(s): Richard Higgins

Year: 2015


This poster focuses on the investigation of sourced obsidian artifacts found in and around the Cañada del Oro Valley in southeastern Arizona. The goal of this study is to understand the evolution of social interaction and obsidian distribution during the pre-classic Hohokam periods (ca. A.D. 700-1150) and how they compare to patterns in neighboring areas. There are no obsidian sources immediately adjacent to the Cañada del Oro Valley or Tucson Basin regions. Therefore, investigation of obsidian distribution allows for a better understanding of the social interactions taking place. Previous studies have indicated that obsidian artifacts are small in number during these periods, but later proliferate. Examination of the patterns during these earlier periods will allow for a better understanding of obsidian distribution as it underwent a major change in the Hohokam Classic period (ca. A.D. 1150-1450).
