The Ah-Shi-Sle-Pah Wilderness is located in northwestern New Mexico and is a badland area of rolling water-carved clay hills. The area is rich in fossils and has little vegetation to conceal geological formations. The thin vegetation includes sagebrush, pińon-juniper, Great Basin scrubland, and grassland. It is a landscape of sandstone cap rocks and scenic olive-colored hills. Water in this area is scarce and there are no trails; however, the area is scenic and contains soft colors rarely seen elsewhere.
