Two moose were caught on video swimming across an alpine lake in the Indian Peaks Wilderness over the weekend.

While the unusual wildlife sightings are gaining a lot of attention online, moose actually love to swim. It helps regulate their body temperature, especially on hot summer days. Standing in just a couple feet of water also helps deter predators, including wolves and mountain lions from attacking.

Moose are capable of swimming up 6 miles per hour for up two hours at a time. Thanks to their extremely long legs, they are able to easily navigate through deep waters and snow.

The Indian Peak Wilderness is a 73,711-acre wilderness area located in north-central Colorado, just west of Denver. Here’s a look at where it’s located on the map.

Colorado offers plenty of opportunities for watching wildlife. Just remember, always keep your distance. Never approach a moose or any other wild animal. Weighing up to 1600 pounds and charging at speeds of 35 mph, an angry moose is no match for a hiker. If a moose attacks you, run. If possible, try to place a large object like a tree or rock between you the moose. In any situation, do your best not to disturb them. Respect wildlife and stay safe out there.
