17,698 acres on the Angeles and San Bernardino National Forests
The Sheep Mountain Wilderness Additions include several tributary canyons of the San Gabriel River, a portion of the San Gabriel Mountains crest between Mt. Baden Powell and Mt. Hawkins, and the upper slopes of Mt. San Antonio. The additions include a segment of the Pacific Crest Trail and the popular East Fork Trail, described in the definitive guidebook Trails of the Angeles as providing “nature in its grandest proportions.” This is an “Area of High Ecological Significance,” with important habitat for the endangered or rare mountain yellow-legged frog, Nelson’s big horn sheep, and California spotted owl. Anglers enjoy the many streams in the area that support resident trout.
