| Alpine chipmunks live only at high elevations in the Sierra Nevada Mountains of California. They are found in rocky areas such as rock-bordered alpine meadows, talus slopes, and rockslides, with such other mammals as pikas, ermine, yellow-bellied marmots, and bighorn sheep. Seeds, small alpine plants, and sedges make up most of the chipmunk's diet, but they also eat fruits, berries, fungi, forbs, and grasses. They are active until mid-October and then hibernate until June.
