The Wolverine State is MICHIGAN. The wolverine (Gulo luscus) is very rare in Michigan, so much so that many have challenged the truth of them ever having been native to the state at all. However, wolverines are solitary hunters with vast territories, so they are not very abundant ANYWHERE. Alaska, Canada, and the northernmost regions of Europe and Asia give them the vast wilderness they require to survive.
There has been enough recent video proof of the wolverine's existence in the state of Michigan, by the Department of Conservation, and the mainstream news media, to substantiate the pioneer's proclamation of Michigan as the Wolverine State (especially as compared to the rest the "Lower 48").
The wolverine is a slow runner compared to many animals its size, but, it has extreme endurance and can run down just about anything over the vast, wide open tundra of the Great North. The wolverine simply chases until its intended victim collapses from exhaustion.
