Incorporated in 1984, Mammoth Lakes is a relatively young town. Mammoth Lakes is located in the Inyo National Forest of Mono County on the eastern flanks of the Sierra Nevada Mountain Range. The town is surrounded by acres of forest and is bordered by the Ansel Adams and John Muir Wilderness Areas. Yosemite National Park's eastern entrance is located just 32 miles north of town and its short 100-mile drive to the valley floor. The town occupies a site in the southern half of Mono County, a stunningly diverse region of eastern California. Comprising 3,018 square miles, the County's area is marked by the startling contrast between its eastern and western boundaries.
Bounded on the west by the Sierra Nevada crest, this region is characterized by its mountains, lakes, streams and forests. Unlike the gentle, rolling escarpment west of the crest, the eastern slope of the Sierra plunges dramatically to the valley floors. This is probably the characteristic of the Eastern Sierra most obvious to the first-time visitor. The Town of Mammoth Lakes is situated in the southwestern, mountainous region of the county, and many of its trails, campgrounds and roads either abut or cross the crest of the Sierra.
Adjacent to town is one of the finest ski resorts in the western United States - Mammoth Mountain Ski Area. Mammoth Mountain Ski Area averages 400 inches of snowfall annually.
