The wolf sighting in northern Colorado was no optical illusion.

Colorado Parks and Wildlife confirmed Wednesday the rare beast to be a from the Snake River pack in Wyoming.

The wolf was last recorded Feb. 12 by transmission signals, parks and wildlife said.

The Wyoming Game and Fishing Department confirmed the reports out of Jackson County, a rural stretch of the state that hugs the Wyoming border.

“We will monitor the area, but are no longer actively pursuing the wolf’s location,” CPW said in a tweet.

Under the Endangered Species Act, harming, harassing or killing a gray wolf other than in cases of self defense is illegal, park and wildlife said.

Another wolf sighting out of Grand County has not been confirmed.

Colorado used to be home to gray wolves before they were eradicated around 1940, according to CPW.

Gray wolves still roam nine states in the Midwest, Mountain West and West Coast.
