San Gorgonio Mountain, also known locally as Mount San Gorgonio, or Old Greyback, is the highest peak in Southern California at 11,503 feet (3,506 m). It is in the San Bernardino Mountains, 27 miles (43 km) east of the city of San Bernardino and 12 miles (19 km) north-northeast of San Gorgonio Pass. It lies within the San Gorgonio Wilderness, part of the San Bernardino National Forest. Spanish missionaries in the area during the early 17th century named the peak after Saint Gorgonius.
Since it is the highest point in a region which is separated from higher peaks (e.g. in the Sierra Nevada) by relatively low terrain, San Gorgonio Mountain is one of the most topographically prominent peaks in the United States. It is ranked 7th among peaks in the 48 contiguous states and 18th among overall.
Several trails lead to the broad summit of San Gorgonio Mountain, which rises a few hundred feet (100 m) above the tree line. Any route requires well over 4,000 feet (1,200 m) of elevation gain.
The trail leading from the Fish Creek Trailhead to San Gorgonio Mountain has about 3,400 feet (1,000 m) of gain, less than the routes from the South Fork and Vivian Creek trailheads. Hikers should always take caution because some junctions on this trail are not well marked.
Aircraft wreckage 
On December 1, 1953, a Douglas C-47 Dakota, serial number 45-1124, crashed at the 11,000 feet (3,400 m) level on the eastern face of the mountain. The C-47 was en route from Offutt Air Force Base, Nebraska to March Air Force Base near Riverside, California when it struck the mountain at night in the middle of a storm. "The aircraft was last heard from at 9:51 p.m. Pacific Standard Time, Monday." Thirteen people died.
Nearly one month after the C-47 accident a Marine Corps helicopter crashed on the mountain in coordination of the efforts of recovering the victims. The three crewmen of the helicopter survived the impact. Most of the wreckage of the two aircraft remain on the mountain and are accessible via the Fish Creek Trailhead or the South Fork Trailhead.
In more recent years, the mountain claimed the lives of Frank Sinatra's mother (January 16, 1977) and Dean Paul Martin (March 21, 1987), son of Dean Martin, in unrelated plane crashes. Martin was an Air National Guard pilot and the McDonnell Douglas F-4C he was flying disappeared in a snowstorm and the wreckage was found on the mountain several days later.
