Columbian ground-squirrel, by Maligne Lake

Golden-mantled ground-squirrel, by Johnston Canyon: very common, often semi-tame especially around places serving food

Hoary marmot: this family (we saw three) had burrowed by the path near Helen Lake, and were completely unafraid of tourists. They are much larger than the ground-squirrels, the adults being about the size of a large cat
