The Alabama Hills location as a gateway to Mt. Whitney and the Eastern Sierra Nevada Mountains has made dispersed camping very popular with the overlanding and RV communities.[5] The region's fragile ecosystem and increasing numbers of visitors to Alabama Hills has prompted the Bureau of Land Management in its most recent guide to the area to discourage this practice asking visitors to, "Camp in campgrounds. Using campgrounds reduces the number of vehicles so that the great views are not blocked. Use the restroom in town or at nearby campgrounds. If that isn’t an option, bury human waste in catholes 6 inches (15.24 centimetres) deep and 200 feet (61 metres) away from water, trails, and camp. There are no restrooms in the hills...Camping in campgrounds helps maintain the area’s great scenery and recreational opportunities. City of Los Angeles Department of Water and Power lands in the area are open for day use only."[6]
The rounded contours of the Alabamas contrast with the sharp ridges of the Sierra Nevada to the west. Though this might suggest that they formed from a different orogeny, the Alabamas are the same age as the Sierra Nevada.[citation needed] The difference in wear can be accounted for by different patterns of erosion.
Mount Whitney, the tallest mountain in the contiguous United States, towers several thousand feet above this low range, which itself is 1,500 feet (460 meters) above the floor of Owens Valley. However, gravity surveys indicate that the Owens Valley is filled with about 10,000 feet (3,000 m) of sediment and that the Alabamas are the tip of a very steep escarpment. This feature may have been created by many earthquakes similar to the 1872 Lone Pine earthquake which, in a single event, caused a vertical displacement of 15–20 feet (4.6–6.1 m).
Lathe Arch
There are two main types of rock exposed at Alabama Hills. One is an orange, drab weathered metamorphosedvolcanic rock that is 150–200 million years old. The other type of rock exposed here is 82–85-million-year-old biotitemonzogranite which weathers to potato-shaped large boulders, many of which stand on end due to spheroidal weathering acting on many nearly vertical joints in the rock.
Dozens of natural arches are among the main attractions at the Alabama Hills. They can be accessed by short hikes from the Whitney Portal Road, the Movie Flat Road and the Horseshoe Meadows Road. Among the notable features of the area are: Mobius Arch, Lathe Arch, the Eye of Alabama and Whitney Portal Arch.
History

The Alabama Hills were named for the CSS Alabama, a Confederate warship deployed during the American Civil War. When news of the ship's exploits reached prospectors in California sympathetic to the Confederates, they named many mining claims after the ship, and the name came to be applied to the entire range.[7] When the Alabama was finally sunk off the coast of Normandy by the USS Kearsarge in 1864, prospectors sympathetic to the Union named a mining district, a mountain pass, a mountain peak, and a town after the Kearsarge.[7]
Filming location
The Alabama Hills are a popular filming location for television and movie productions, especially Westerns set in an archetypical "rugged" environment. The first known movies to be filmed in the Alabama Hills are Water, Water Everywhere and Cupid, the Cowpuncher, both shot in 1919 and released in early 1920. These films are currently considered lost films. The oldest surviving film shot in the hills is The Round-Up (1920), starring Roscoe "Fatty" Arbuckle, which includes a cameo from his friend, Buster Keaton.[8]
In Lone Pine, the closest town to the Alabama Hills, the Lone Pine Film History Museum explores the area's relationship to the art of cinema. Exhibits include the Dr. King Schultz dentist wagon from Django Unchained and the 1937 Plymouth Humphrey Bogart drove in High Sierra.[11] Every Fall the Lone Pine Film History Museum hosts the Lone Pine Film Festival, which bills itself as "the only film festival on location," because festival-goers watch films shot in the area and then take tours into the Alabama Hills to see the very spots where the scenes they just watched were filmed.[12]
Astronomy
The Alabama Hills feature exceptional skies for Central California. It is Bortle class 2 or "average dark sky" site; this low level of light pollution meets or exceeds conditions in many of other popular nearby areas for amateur astronomy, such as Joshua Tree National Park (Bortle class 2–4).[13] On a clear night with no moon, a visitor with good, dark-adapted vision may see the Andromeda and Triangulum galaxies with the unaided eye; the central Milky Way appears highly structured under these conditions.[14]
