Some of the thirty landforms in the fold-and-thrust-belt listed in a circular path around these three ranges are: 1. NE, Alamo Lake State Park, NE Buckskin Mtns; 2. Access roads from U.S. Route 93, northwest, dirt, and southwest, Arizona State Route 71 terminating at Aguila, Arizona, at the northeast of the Harquahala's; 3. Southeast of the Harquahalas, three mountain ranges, and the Hassayampa and Harquahala Plains-(Harquahala Valley); 4. The southwest and west perimeter of the three ranges is the Bouse Wash Drainage; the drainage is in the Ranegras Plain, but two small ranges, and the Bouse Hills abut the perimeter as well; 5. The northwest abuts the Cactus Plain and the Cactus Plain Wilderness; 6. The northwest also has the Buckskin Mountains extending into a western section at the confluence of the Colorado and Bill Williams Rivers. Buckskin Mountain State Park is located here. 7. The Bill Williams River downstream from Alamo Lake State Park is the northern border of the three ranges, as well as the de facto border of fold-and-thrust-belt. The river is also a dividing line between the Mojave Desert north and northwest, and the Sonoran Desert, south and southeast; in California, the Colorado Desert subsection of the Sonoran Desert lies southwest.
