In mountainous regions, summers in alpine meadows, winters in valleys. On more level terrain, seeks wooded hillsides in summer, open grasslands in winter. Pacific coast populations are more sedentary than are those elsewhere. Migrates from areas with deep snow. Some individuals in Jackson Hole, Wyoming, migrate up to 97 kilometers annually (Adams 1982).
