U.S. Fish and Wildlife Service (FWS) has received lab results confirming that the Skagit County animal they collared in June is definitively a gray wolf.

Photos taken by Marvin Kempf between the towns of Marblemount and Rockport earlier this spring showed what officials believed to be a gray wolf, about 100 miles from the closest known wolf packs. For a wolf, though, 100 miles is nothing.

FWS tried to trap and collar the wolf over 10 days but were unsuccessful. They returned a second time mid-June and found the predator, collaring it with GPS.

Tracking data shows the wolf is still in the same area and has likely made a home there.

The wolf may be related to other packs located in central Washington, such as the Lookout pack in the Methow Valley or the Teanaway pack near Cle Elum.
