About San Gorgonio Wilderness
Overview 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. History San Gorgonio Mountain was originally known as "Old Grayback" by locals until officially designated by the US Geological Survey (from the Spanish heritage) on the original topographical map of the area produced in 1899. At 11,502 feet, it is the highest peak in California south of the Sierras. The San Gorgonio Wilderness derived its name from this peak
