This wilderness is part of the eastern slope of the San Bernardino Mountains with topography rapidly changing from low, rolling foothills and canyons to steep, rugged mountains. Elevations range from 2,300 to 5,500 feet. Because of this elevation gradient, the wilderness reflects a unique transition between desert, coastal and mountain environments, including the different types of vegetation representative of each elevation.
