The Hoary Marmot is the largest North American marmot, with a distinctive frosted-gray coat and black-and-white facial markings. It inhabits alpine terrain near timberline in Alaska and the Pacific Northwest. Hoary marmots are a critical food source for bears and eagles fattening up before winter, and their loud alarm whistles are an iconic sound of high mountain environments.
