Alaska records for this species concentrate almost entirely on the North Slope and the Brooks Range, with a handful more from Arctic National Wildlife Refuge. That isn’t a data quirk. This is genuinely the whole US range for the Alaska marmot, a narrow band of treeless peaks entirely north of the Arctic Circle. Nowhere else in the country, including the rest of Alaska’s mountains, holds this species.
Colonies dig burrow systems into talus slopes and boulder fields, usually within reach of a lake or stream where the ground actually thaws each summer. They pack on grasses, sedges, and tundra flowers as fast as they can find them, since a marmot here needs enough fat by early fall to carry it through eight months or more of hibernation. Sharp alarm whistles, the habit that earns marmots the “whistle-pig” nickname across the genus, warn the whole colony the moment one animal spots trouble.
Recorded sightings run only from June through September, and that narrow window is a direct reflection of the marmot’s biology rather than an observation gap. For most of the year, every Alaska marmot in the state is asleep underground.
