Alpine Chipmunk

About the Alpine Chipmunk

The alpine chipmunk (Neotamias alpinus) is a species of chipmunk native to the high elevations of the Sierra Nevada of California. No significant threats to the species are known. Alpine chipmunks share the typical pattern of genus Neotamias, being gray-brown overall and featuring three white stripes on the cheeks and four down the back. The flanks are muted orange. They weigh 27-45 grams and grow from 166 to 203 mm. Overall the alpine chipmunk is much paler and smaller compared to others in its genus. Their typical lifespan in the wild is up to 2-3 years.

Alpine chipmunks only live in high Sierra Nevada, from Yosemite National Park in the north, to Olancha Peak in the south. They have been observed at altitudes from around 2,300 meters (7,500 ft) to 3,900 meters (12,800 ft), though they rarely occur below 2,500 meters (8,200 ft). They primarily inhabit the talus slopes and sub-alpine forests, where there is a large accumulation of loose, rocky debris. During the summer, where the high-elevation environment becomes increasingly arid and warm, the alpine chipmunk utilize these rocks by retreating into the cool, deep crevices of boulders...
