dc.descriptionThe Palomas Mountains are located approximately 70 miles northeast of Yuma, Arizona, and about 15 miles north of the town of Dateland in eastern Yuma County (Figure 1). Across a narrow valley to the north are the Tank Mountains, which form a continuous belt of bedrock westward into the Kofa Mountains. To the west lies Neversweat Ridge, which is the eastern-most known exposure of Orocopia Schist. To the east and northeast is the Palomas Plain, and to the south is the Gila River. Accessibility to the range is generally good. Most of the dirt roads are in good condition and can be partially traversed by a two-wheel drive vehicle. However, because they cross many sandy washes the roads are only passable with a four-wheel drive vehicle. The western half of the range lies within the Yuma Proving Ground and permission must be obtained before entering. Besides the current munitions testing on the Proving Ground most of the southern portion of the mountains was the site of military training during World War II. Rusted fragments of shrapnel, small craters, and tank and vehicle tracks are numerous. Two miles west of the curve in the paved road heading north from Dateland is a monument commemorating the training of the 81st Infantry Division.
