Encompassing 154,000 acres, including just over 100,000 acres of already congressionally-designated Wilderness, Sand to Snow National Monument is an ecological and cultural treasure and one of the most biodiverse areas in southern California, supporting more than 240 species of birds and twelve threatened and endangered wildlife species. Home to the region?s tallest alpine mountain that rises from the floor of the Sonoran desert, the monument also will protect sacred, archaeological and cultural sites, including an estimated 1,700 Native American petroglyphs. Featuring thirty miles of the world famous Pacific Crest National Scenic Trail, the area is a favorite for camping, hiking, hunting, horseback riding, photography, wildlife viewing, and even skiing.
