Abstract
Approximately 460 Hohokam petroglyphs from Tumamoc Hill (AZ AA: 16:6), a “fortified” hill (trincheras) just west of Tucson, are discussed. A new style of prehistoric rock art—Hohokam Scratched style—is described. Dating, typologies, analyses, and interpretations of petroglyphs are discussed for Tumamoc Hill in particular, for Tumamoc Hill as compared to other Tucson Basin petroglyph sites, and to Hohokam rock art in general.
