Wolverines have one of the largest territories of any North American mammal. 200 Sq mi. is not uncommon. Your chances of lightning strike are much higher than a wolverine encounter. They are very rare.
Wolverines can't break into a bear canister, but they might drag one several miles away before they give up. Same thing for bears though, they may not get your food, but they’ll sure ‘hide’ it for you. Wolverines are immensely strong. They have been seen dragging caribou for almost a mile, 60lb critter dragging a 250lb one, pretty impressive.
Being the largest member of the weasel family, they can be extremely ferocious. However, they are not going to charge you if surprised, like a bear or large ungulate might do. Their ferocity is usually directed towards wolves, bears and eagles. This would be to secure their kill, or to steal food from said animals.
Wolverines, lions, tigers and bears, {Oh my}, are nothing compared to biting dogs and their idiot non-leash using owners. I’ve had far, far more dangerous encounters with dogs than with any wild animal, and I live in Alaska where I’m not at the top of the food chain.
At least wolverines don’t go running by me, off leash, on a tight trail next to cliffs, almost knocking me over the edge, while their clueless owners are chatting on their cell phones.
Come to think of it, wolverines don’t crap on the trail and smell up the forest for the rest of the summer either.
I like wolverines.
