The South Mountains in Phoenix contain more than 8,000 ancient petroglyphs. This program will discuss Dr. Bostwick’s long-term study of these Hohokam petroglyphs and will describe the various types of designs, their general distribution, and their possible meanings. Interpretations of the petroglyphs include the marking of trails, territories, and astronomical events, as well as dream or trance imagery based on O’odham (Pima) oral traditions. Most of the trails currently used by hikers in the South Mountains contain Hohokam rock art, indicating that these trails date back at least 800 years.
