At least one wolf wandered into parts of southern Jefferson County and western Douglas County in the last month, according to the Colorado Department of Parks and Wildlife.
None of the wolves living in Colorado have approached urban areas or attempted to cross Interstate 25, the department said.
A map of the wolves’ movements since late February showed at least one passed through watersheds as far west as the Utah state line and as far east as Teller County, ranging between the Wyoming state line and northern Gunnison County.
A separate wolf or wolves wandered in the Durango area and the San Luis Valley.
Some wolves have established territories, while others roam more broadly, the department said. Colorado has 18Â wolves outfitted with collars, plus pups and others that wandered from neighboring states.
Wolves typically establish their dens in April, limiting their movement. During that time, the females stay with the pups, while the males hunt in the surrounding area.
