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 within its boundaries. The Wilderness is located in the southeast portion of the San Bernardino Mountains on lands administered by the San Bernardino National Forest and the Bureau of Land Management. Most of the Wilderness is above the 7,000 foot level. Two rivers (which would be called creeks anywhere but in Southern California), the Santa Ana and the White, flow out of the Wilderness. The numerous streams in the Wilderness Area do not always flow in late summer, and locating water can be difficult. Two small lakes, several meadows, and large, heavily forested areas provide a beautiful sub-alpine oasis in the dry lands that surround the mountain range. The isolated environment contains many threatened and endangered plant and animal species, as well as bear, deer, mountain lions and bighorn sheep. The summit of the 10,624-foot San Bernardino Peak provided the initial point in 1852 from which all of Southern California was surveyed. This 1.5 inch = 1 mile scale map shows 100 ft contour lines, shaded relief, forest cover, trails, roads, recreation opportunities, lakes, rivers and numerous survey points and boundaries. This map is to be used with the San Bernardino National Forest Motor Vehicle Use Map (MVUM). The MVUM shows the National Forest System roads, National Forest System trails, and the areas on the National Forest System lands in the San Bernardino National Forest that are designated for motor vehicle use pursuant to 36 CFR 212.51. National Forest road, trail and area users must comply with the MVUM, as well as Federal, State and local laws and regulations. Compliance with these rules is the responsibility of the user.
