In April 2016, a coyote hunter killed a wolf near Kremmling, and he turned it in to the DOW, a 75lb male, if I recall.
Another coyote hunter killed a wolf on the North side of the Grand Canyon last year as well.
Both wolves were DNA traced back to the Yellowstone packs.
If there are no established packs here yet, I think it's only a matter of time.
