Repost.
This post was split off from an earlier post that got too large, California Wolverine Re-discovered After 85 Years. This particular post will deal with the question of wolverines in the states of Utah and Colorado.
Wolverines in Utah
The Manti-La Sal National Forest in Utah in Sanpete County. This county in central Utah is believed to harbor a wolverine population. This area is northeast of Fillmore, Utah, which is the sighting nearest to Nevada.Also in March 1979, a man junction with Coyote Gulch (Wolverine Bench” on the map in the Escalante Canyon area, and wolverines used be found into Northern Arizona. If wolverines existed in Northern Arizona, clearly they existed in the Glen Canyon area. Wolverines live in very similar habitat in the Snake River Canyon in Idaho.
The Upper Escalante River Canyon is in the Aquarius Plateau, which has 50,000 acres of land above 11,000 feet. That’s clearly wolverine habitat. The junction of Coyote Gulch and the Upper Escalante is a ways away from the plateau, but it’s likely a dispersing juvenile could be found in the area. A photo of the terrain is here.
In recent years there have been documented sightings of wolverines around Salt Lake City and the Great Salt Lake. One was photographed running through a suburban development!
Wolverines in Colorado
There was an unconfirmed and undated sighting of a wolverine chasing a boy on a motorcycle down a road in the Routt National Forest in far Northern Colorado some years ago. The Routt is near Steamboat Springs up by the Wyoming border.
There have also been incredibly, near Sterling on the Great Plains in Northeastern Colorado, which seems very odd, but looking through all of these reports, it becomes apparent that wolverines in Wyoming, Oregon, Idaho, Utah, Iowa, and Minnesota may indeed use prairie habitat.

Click to enlarge. I think it is quite clear by now that wolverines do use prairie habitat. Even aboriginally, prairie was thought to be marginal for wolverines, but perhaps that was wrong. Pre-contact, vast herds of buffalo roamed the prairie, and there would be plenty of dead buffalo for the scavenging wolverine to eat.Recently, there was an unconfirmed wolverine sighting 4-5 miles up Red Sandstone Road in Vail, Colorado on the White River National Forest.

The famous Maroon Bells in the White River National Forest in Western Colorado. Aspen and Vail are also located in this forest. I spent a week skiing in Aspen in 1978. Great place! The White National Forest is believed to harbor a wolverine population. Along with Pike NF, these may be the only populations in the state.Wolverines are present in Colorado on the Pike and White River National Forests and in Utah in the Wasatch and Uinta Mountains and in Sanpete County in Central Utah.
