But instead of a wolf, it was a wolverine! Following his tracks back down the trail, I saw that he had been running along stealing lynx bait, as they are so famous for doing. Wolverines are the largest member of the weasel family (between 15 and 35 pounds), which includes marten, mink, ermine, and skunks. These guys are built like tanks. They're basically just muscle, tendon, claws, and teeth, combined with the attitude of a grizzly bear. More than anything, wolverines are known for being wily and hard to catch.
