The Hassayampa River flows freely for several miles along the southern and eastern portions of this Wilderness, supporting a riparian habitat. The area reaches a high point on Sam Powell Peak at 4,015 feet in the western portion, where you'll also discover a striking geological monolith called The Needle. Side canyons and uplands are covered in chaparral, paloverde, and saguaro. Visitors come to backpack or horsepack and to photograph the landscape. Private land exists adjacent to the wilderness boundary and should not be crossed without prior permission to access the wilderness trails.
