There are two main types of rock exposed at Alabama Hills. One is an orange, drab weathered metamorphosed volcanic rock that is 150-200 million years old. The other type of rock exposed here is 90 million year old granite 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.

Mount Whitney, the tallest mountain in the contiguous United States, towers several thousand feet above this low range, which itself is 1,500 feet above the floor of Owens Valley. However, gravity surveys indicate that the Owens Valley is filled with about 10,000 feet 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
