The Sierra National Forest lies east of Fresno in central California, and west of the Sierra Nevada Crest between Yosemite and Sequoia-Kings Canyon National Park. The Forest varies from brushy front country to dense forests and barren alpine peaks and valleys. Elevations range from 900 to 13,000 feet. The most popular and developed areas in the Forest are at Bass Lake, Mammoth Pool, Shaver Lake, Huntington Lake, Mono Hot Springs, Lake Edison, and Dinkey Creek. Waterskiiing, sailing, stream and lake fishing are popular. The John Muir and Minarets Wildernesses are very heavily used in July and August. The Monarch Wilderness is lightly used.
