The San Gorgonio Pass el. 1,591 ft (485 m) cuts between the San Bernardino Mountains on the north and the San Jacinto Mountains to the south. Like the Cajon Pass to the northwest, it was also created by the San Andreas Fault. The pass is not as steep as the Cajon or the Tejon passes, but it is one of the deepest mountain passes in the 48 contiguous states, with the mountains to either side rising almost 9,000 ft (2,700 m) above the pass.
San Gorgonio Mountain is at the pass's northern end, and Mount San Jacinto is at the southern end. Mount San Jacinto has the fifth-largest rock wall in North America. The peak is only six miles south of Interstate 10. Today the San Gorgonio Pass is used by commuters from the Greater San Bernardino Area to travel through the mountains to Palm Springs and the Coachella Valley, and points further east, all the way to Phoenix, Arizona.
