MOOSE, Wyo. — Moose have evolved to endure the coldest temperatures and to stride through the deepest of snow in and around Jackson Hole.
According to Grand Teton National Park (GTNP), moose grow the perfect winter fur with long, hollow strands of hair that make up a very thick, dense undercoat trapping air and keeping them warm. Their chocolate “moose” color helps them absorb every ray of sunshine and their nasal passages are even designed to heat air when it’s inhaled which warms their lungs. They also conserve energy by not growing antlers in the winter, moving around less and saving their system’s resources for survival.
Moose during the winter eat twigs, grass and leaves called “browse.” These herbivores also eat a lot in the fall to stock up on nutrients and rely on their fat storage during the coldest months, when food is scarce.
Moose are muscular and have long legs so moving through a few feet of snow isn’t difficult for them. They are mostly solitary, but it’s not uncommon to see two together, as calves stay with their mom for about one year before they venture off on their own.
GTNP reminds the public to stay at least 25 yards away if they see a moose in the wild. They need to reserve lots of energy to survive the long winter months in the Tetons.
