Occurs in alpine and subalpine talus, rock fields, and meadow edges where cool crevices lie close to foraging areas.
The body is rounded, ears are short and round, and the tail is barely visible. Gray-brown fur blends with rock.
Active by day, it gives sharp calls to mark territory. From summer to autumn it cuts plants and stores hay piles under rocks.
Forbs, sedges, flowers, and leaves are eaten. Stored plants are dried and used as winter food.
Nests are placed in rock crevices, and small litters are born from spring into summer. Young develop in the nest before emerging.
The species is low-risk overall, but heat sensitivity makes some low-elevation populations vulnerable to warming.
