Wolverine

Gulo gulo

Also known as Carcajou, Glutton, Quickhatch, Skunk Bear

Wolverines wander vast, snow-covered territories across northern wilderness, patrolling hundreds of square kilometers in search of carrion and small mammals. Equipped with dense, frost-resistant fur and oversized paws that act as natural snowshoes, they thrive in punishing subzero environments. Females dig deep maternity dens within persistent spring snowpacks to nurse and shield their kits from severe weather and predators.

Why interaction risk is low
Possesses formidable teeth and jaws; do not approach or corner a wild individual.
Why it is dangerous
Equipped with powerful crushing jaws and sharp claws adapted for tearing frozen flesh and bone, which can inflict traumatic wounds if cornered.
How to recognize a risky encounter
Look for a stocky, bear-like profile with dark brown shaggy fur, a bushy tail, and yellowish side stripes.
What to do
Never approach, corner, or attempt to feed an individual; slowly back away while facing the animal.
What to notice
Watch for solitary tracks crossing high alpine ridgelines or remote subalpine avalanche chutes.
Support conservation
Avoid entering high-elevation cirques and late-season snowfields during early spring denning periods.
Responsible observation
  • Distance: Maintain a wide berth of at least 100 meters if spotted in the wild.
  • Storage: Secure all food and waste in bear-proof containers while backcountry camping.
  • Snow Tracking: Look for large, five-toed tracks with claw marks in high-elevation snowfields.
