The Sears Point Archaeological District is an extensive complex site across terraces south of the Gila River and west of present day Gila Bend with over 2,000 panels of petroglyphs. Volcanic cliffs, basalt mesas, and boulders are characteristic of the area. There are thousands of petroglyph elements and archaeological elements including geoglyphs, rock piles, rings, alignments, cleared areas, trails, and historic features from the 1800s as well as temporary habitation. Sears Point was most likely a major prehistoric gathering location for collection of food resources and regional ceremonies. Prehistoric cultures represented are probably Desert Archaic, Patayan, and Hohokam with a strong possibility of a Paleo Indian presence. "An Archaeological Record of the Sears Point Petroglyph Complex" is based on the 4-year project and resulting final report and analysis on file with the Yuma Field Office of the Bureau of Land Management. From Paleo Indian times to the present, this crossroads of fertile riparian habitat has been utilized by various visitors who left enticing visual clues to their presence and activities within the fragile desert environment.
