This report includes the area between Webb Mountain and Yellow Medicine Butte in the central Gila Bend Mountains, approximately 30 kilometers northwest of Gila Bend, Arizona. The study area includes part of the Woolsey Peak Wilderness Study Area, all of the Signal Mountain Wilderness Study Area, and the following four U.S.Geological Survey, 1:24,000 scale 7.5' topographic quadrangles; Fourth of July Butte, Gillespie, Quail Spring Wash, and Woolsey Peak (plate 1; Figure 1). Several well-graded dirt roads provide access to much of the area but do not extend into the wilderness areas. The Agua Caliente Road is the major artery slicing east-west through the center of the map area. There is also a good service road paralleling the Southern Pacific Railroad, and several well-kept roads in the Harquahala Plain and east of Mullen's Cut (Figure 2).Additional Links
