Tamias dorsalis Baird, 1855 The cliff chipmunk (Neotamias dorsalis) is a small, bushy-tailed squirrel that typically lives along cliff walls or boulder fields bordering Pinyon-juniper woodlands in the Western United States and Mexico (commonly spotted in northern Arizona to Colorado).

Cliff chipmunks do not amass body fat as the more common ground squirrel does.

The chipmunks' size varies from 8 to 10 inches (20 to 25 cm), and they weigh an average of 2.5 oz (70 g).

The chipmunks are brown on their underside and gray on the back, with white stripes on their face.

The chipmunk's diet consists of juniper berries, pine seeds, and acorns.
