What the sources say

Range: In Colorado, Moose are most abundant in North Park and on the Grand Mesa, but have expanded their range to include most of the mountainous regions of Colorado, including along the Front Range, where moose can occasionally be found wandering as far east as Golden, Boulder, and Colorado Springs.

Habitat: Moose live in forested areas that are often close to lakes and marshes. They are very territorial, will defend their space, and rarely leave their home territory during winter. (Colorado Parks and Wildlife)

All mammals in the state: Colorado mammals.
