Alabama Hills, California


The Alabama Hills are a range of hills and rock formations near the eastern slope of the Sierra Nevada west of Lone Pine California.

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 82- to 85-million-year-old biotite monzogranite 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.
