Colorado and Washington State see wolverines in new places.
In recent years wolverines have been seen in places where they were not expected. Is this because people are looking for them or are they expanding their range? One wolverine in an isolated location does not mean that there is a sustainable population. There have been reports of radio tagged wolverines which have travelled very long distances across what would seem to be unsuitable habitat.
Recall the wolverine sighted in California on two occasions.
Here are two recent stories about wolverines in Washington State and Colorado.
