The Way of the Wolverine

After all but disappearing, the mammals are again being sighted in Washington's Cascade Range.

Wolverine are one of the most elusive and least understood mammals in North America. Up to four feet long and 40 pounds, wolverines are the largest terrestrial members of the mustelid, or weasel, family. Wolverines thrive in the cold, and can sniff out carcasses through six feet of snow. They raise their kits in caves dug into snow, with chambers and tunnels leading dozens of feet away from the den. Their feet are outsize, like snowshoes, and they can walk 50 miles or more per day across steep, snowy terrain.
