Waterman Mountain, at 8,041 feet (2,451 m), is a prominent peak in the San Gabriel Mountains of Los Angeles County, California in the Angeles National Forest. The summit of Waterman Mountain marks the northern boundary of the San Gabriel Wilderness and it is the highest point in the wilderness. Several small ski areas are located on its north side: Mount Waterman, Kratka Ridge, and Buckhorn Ski Club. The Buckhorn and Cooper campgrounds are below the Angeles Crest Highway. During winter and early spring this mountain is packed with snow. Snow may even be found in September lying on Waterman mountain. Spring brings a lot of rain and makes Waterman covered in wildflowers. Summers are hot and dry. The climate here is Highlands/Mediterranean.
