The Buckskin Mountains is a mountain range in La Paz County, Arizona, United States. The range lies just east of the north–south Colorado River, and borders south of the east–west, west-flowing Bill Williams River. Description The range is part of a three-range sequence of mildly arc-shaped ranges, and two intermountain valleys in the Maria fold and thrust belt, a region in western Arizona and southeast Southern California, with the Colorado River flowing south through the western part of the belt. The fold-and-thrust-belt region contains numerous plains, valleys, and mountain ranges, about 30 landforms in all. The Buckskin Mountains also extend west into a section abutting the Colorado River. Buckskin Mountain State Park borders the south of the Bill Williams River. Buckskin Mountains: west, central, and southeast The southeast section of the Buckskin Mountains are part of a three-mountain range thrust-faulted system, with the Harcuvar and Harquahala Mountains. The highest peak in the section is Battleship Peak, , at the southwest end, and directly northeast of Bouse in the Ranegras Plain, and the Bouse Wash Drainage. The west end of the mountains abut the north–south Colorado River. Located here is the Gibraltar Mountain Wilderness, with Gibraltar Mountain, at . The entire north perimeter of the range is the Bill Williams River. Buckskin Mountain State Park is at its confluence in the northwest at the Colorado River. Abutting the Bill Williams in the center is the Swansea Wilderness; the northeast contains the Rawhide Mountains Wilderness on both sides of the river. The northeast of the range borders Alamo Lake State Park-(Alamo Lake), which also borders the Rawhide Mountains on the lake's northwest. Another peak in the central-west, away from the range's east–west centerline, at the south is Planet Peak, at . Planet Peak is directly adjacent at the northeast of the Cactus Plain and the East Cactus Plain Wilderness. The most easily identifiable Peak is "Black Peak," at to the South East. It is known to locals as "P Mountain" due to the large white "P" painted on its west side by the nearby town of Parker. Three major thrust-faulted ranges The major mountain ranges that are thrusted northwesterly in the Maria fold and thrust belt region are, from north to south: Buckskin Mountains Butler Valley (Arizona) Harcuvar Mountains McMullen Valley Harquahala Mountains Some of the thirty landforms in the fold-and-thrust-belt listed in a circular path around these three ranges are: 1.
