Wolverines are one of the most elusive wildlife species in the world, but Glacier National Park boasts one of the highest densities of the mammals. Along with small numbers due to previously unregulated trapping and habitat loss, the creatures prefer the isolation of cold, backcountry mountains.
The U.S. Department of the Interior recently shared wolverine footage from several years ago captured by a Glacier National Park park ranger. The video shows a lone wolverine walking a scree field.
The population in the lower 48 is listed as an endangered species, though researchers are optimistic that the species is slowly recovering.
The wolverines in the Glacier tend to stick to subalpine fir forests in remote areas of the park, but the creatures are highly nomadic, so you never know when or where one might turn up. Catching sight of a wolverine is a rare and memorable event.
Wolverines remain active all winter, as their physique is well suited to snowy terrain. They have short, stocky legs with five-toed paws that give them the ability to travel easily through snow. They also have thick, oily fur that is resistant to frost.
What to do if you encounter a wolverine
Researchers have determined there are about 50 wolverines who call Glacier National Park home. With low population densities and large habitats, the odds of you running into a wolverine are slim, but not zero.
If you encounter a wolverine, be sure to take a deep breath and be in the moment. Wolverines are generally shy and will avoid human interaction, but they can be aggressive if cornered or provoked. As with all wildlife, a general distance of 25 meters or more should suffice.
If you unexpectedly come upon a wolverine and startle it, back away slowly and give the animal plenty of space. Wolverines are more likely to run away than to engage in aggressive behavior.
