Arrastra Mountain

The Poachie Range is a moderate length mountain range and massif in southeast Mohave County, Arizona, and the extreme southwest corner of Yavapai County; the range also abuts the northeast corner of La Paz County. The Poachie Range massif is bordered by the south-flowing Big Sandy River on its west, and the west-flowing Santa Maria River on its south; both rivers converge at the Poachie Range's southwest at Alamo Lake in Alamo Lake State Park.

From Alamo Lake, the (short) Bill Williams River flows due west for 35 mi to meet the Colorado River. The Bill Williams River is the de facto border between the Mojave Desert north and northwest; the Sonoran Desert is south and southeast. Across the south-flowing Colorado River to the west, is the massif of the Whipple Mountains at the northeast of the Sonoran Desert subsection named the Colorado Desert of southern California and bordered by the Colorado River.

The entire region south of the Poachie Range, and its two mountain ranges bordered westwards, the Rawhide and Bill Williams Mountain, and bordered on the Bill Williams River northern bank — is the Maria fold and thrust belt. The thrust belt is a geographic and geologic region at the convergence of these neighboring mountain ranges, rivers, the Alamo Lake, as well as other plains and valleys.
