| Panamint chipmunks are named for the mountains in the Southwest where they were first collected by scientists, in 1890. As with many chipmunks, males and females look alike and are the same size. They live in pinyon pine and juniper forests, in relatively dry habitat with thin, rocky soil that is not good for burrowing, so they find shelter in rock crevices. On some of the mountains where they live, pinyon pine and juniper trees cover the tops of the mountains. On other, higher mountains, sagebrush and boreal conifers grow above the pine-juniper zone, which is not suitable habitat for this species. The Panamint Chipmunk is restricted to pinyon pine and juniper forests at elevations between 1,500 and 2,600 meters (4,900 – 8,500 feet). Panamint chipmunks occasionally hibernate, but are often active on mild winter days.
