- Generally tan in colour with a white spotted back.
- Short and fat with a long thin tail.
- There are also small populations of melanistic ground squirrels that are totally black in colour.

Yukon population estimate
Arctic Ground Squirrels are social animals that live in scattered colonies to allow for greater safety from predators by having many eyes on watch. They are not territorial but males will defend a small home-range from other males. They hibernate from early-October to mid-April. Arctic Ground Squirrels are fat-storing hibernators and are able to supercool their bodies to -2.9˚C while keeping their brains just above freezing. This is colder than any other mammal in hibernation.

Arctic Ground Squirrels and people
- For First Nations people, the Arctic Ground Squirrel was a welcome treat when they emerged from hibernation in spring. Women trapped squirrels in snares made of twisted sinew and squirrels were considered at their best in late-summer.
- Pelts were traditionally used for making robes and trimming ceremonial garments, though there are few markets for ground squirrel skins today.
