The Alaska marmot is a large, ground-dwelling rodent. It has a heavy body with short neck and bushy tail, powerful legs and feet, and claws well-suited to digging. An adult pelage (coat) is solid black on the dorsal surface of the head and nose, and gray and light brown elsewhere on the body. Distinguished from hoary marmot by its darker face and rump and much softer fur; it also lacks the white patch on the snout.
Marmots are most active in early morning and late afternoon, although they may leave their burrows during other daylight hours. Marmots need wind to control mosquito levels and rarely venture out on calm days. The Alaska marmot marks its territory by rubbing its face and glands on rocks and along trails.
