General Location Maps Contacts Area Management Wilderness Laws Images


The United States Congress designated the Ah-shi-sle-pah Wilderness (map) in 2019 and it now has a total of 7,242 acres. All of this wilderness is located in New Mexico and is managed by the Bureau of Land Management.


The Ah-shi-sle-pah Wilderness is located in northwestern New Mexico and in badland area of rolling water-carved clay hills with little vegetation to conceal geological formations including interesting hoodoos. . The area is rich in fossils, having yielded numerous specimens important to science, as well as containing petrified wood including stumps still in an upright growth position complete with roots. . A minor drainage runs through a wide, barren valley bordered to the north and south by a strip of eroded cliffs, ravines and badlands containing innumerable hoodoos, balanced rocks and other strange formations of a great variety of colors. Especially distinctive are the brown-ochre of the badlands, yellow-orange of some of the hoodoos, grey-white of the mud hills lining the valley floor, and deep black of scattered coal beds closer to the wash. The thin vegetation includes sagebrush, pi?on-juniper, scrubland, and grassland.
