It is endemic to Colorado, Utah, Arizona and New Mexico in the United States.

[1][2] It can be found most often in coniferous forests, woodlands, montane shrub lands, and alpine tundra habitats.

Chipmunks are distinguished from ground squirrels in that their faces have a stripe going across under the eye.

Most commonly copulation occurs in the spring when the chipmunks emerge from their burrows.

About a month after copulation, the female will give birth to a litter that may have anywhere between 5-8 altricial young.
