in 2012, partnering with Donald E. Weaver, Jr., we completed a 4-year project with the BLM Yuma District, to document the rock art and other archaeological features of approximately two square kilometers within the Sears Point ACEC, on the Gila (generally-dry) River. With the assistance of many volunteers, we have mapped and documented about two thousand petroglyph panels. In addition, we have mapped about 30 km of trails and almost a hundred other archaeological features (rock rings, rock alignments, etc.). We have resorted to hot-air balloon and light aircraft to photograph some of the features.  On this project, we made use of many panoramas, and a sub-meter Trimble GPS.
