Scientists in Denali have documented 39 species of mammals that range in size from tiny shrews that can weigh as little as a penny to enormous moose that can weigh over 1,200+ pounds.
The Big Five
For many visitors adventuring to the park, a major goal is to see wildlife. Five mammals in particular capture visitor's imaginations and are so popular they are now referred to as the big five. The assortment includes gawky moose browsing in the willow, throngs of caribou loping across the tundra, the iconic Dall sheep nestled high on the hillsides, formidable wolves on the prowl, and lumbering grizzly bears devouring blueberries.
Creatures Great and Small
Other mammals in Denali may be less alluring but are no less interesting and important. Sit on a talus slope and you might discover a collared pika gathering food for winter, a hoary marmot lounging in the sun on a rock, or a red fox carrying an arctic ground squirrel back to its den.
