The small
massif of the mountains is surrounded by two large ranges, northwest and northeast, the
Bull Valley and
Pine Valley Mountains. Bordering southwest is the smaller
Beaver Dam Mountains. Between the Beaver Dam and Bull Valley Mountains, are river courses, streams, or washes, and encircling the west and northwest foothills is the
Santa Clara River. It has multiple source streams, but the river arises off the southeast,
escarpment-type flank of the Bull Valley Mountains, that lies northwest and north of the Red Mountains. The southeast portion of the Red Mountains contains
Snow Canyon State Park, which extends south and southeast beyond the mountains. The park is also about 7-mi in length. The small Red Mountains are nearly circular except on its southeast where Snow Canyon and West Canyon merge into Snow Canyon. The highpoint of the range is unnamed, but is about . ==Access==
