Arrastra Mountain Wilderness

Wild and remote, difficult to access, this sprawling Wilderness preserves imposing landscapes and vividly colorful geologic features. The Poachie Range runs northwest-southeast through the north-central portion of the area and rises from 1,200 feet in the lowest points of the Wilderness to almost 5,000 feet. Southern slopes descend gradually and are interspersed with isolated volcanic plugs and numerous drainages, several of which have been incised deeply into bright orange mudstone. The western and southern portions of the Wilderness encompass more than 20 miles of the ephemeral Big Sandy and Santa Maria Rivers. On the west side of the Big Sandy stands Artillery Peak, a nearly 3,200-foot volcanic plug dominating the Artillery Mountains.
