The tributaries of three canyons are in the WSA. The canyons are from a few feet to a half-mile wide and are characterized by a wide range of colors, sheer walls, and many large overhangs. The canyons converge in the northern portion of the WSA to form Horseshoe Canyon. Weathered sandstone benches, covered in places by grassy parks, separate the canyons. Buttes, domes and sand dunes are also found in the WSA.
