Mount San Antonio

Mount San Antonio, also known as Mount Baldy, is the highest peak in the San Gabriel Mountains, and the highest point in Los Angeles County. Mount San Antonio's sometimes snow-capped peaks are visible on clear days and dominate the view of the Los Angeles skyline. The peak is called Baldy because of the absence of trees around the summit. Mount San Antonio, along with the nearby peak known as Thunder Mountain, is currently home to the family owned and operated ski resort Mount Baldy Ski Lifts, the closest resort to Los Angeles. Hiking trails access the summit from three sides of the mountain. The "Baldy Bowl" is popular with mountaineers; sections of the Bowl are steep with slopes of 45° to 50°.
