Finding Hoary Marmots on Jasper National Park

According to a hoary marmot species profile by Gustav Yaki, the place to find marmots in Alberta is in higher elevations.  He says between 2,100-2,450 m (6,800-8,000 ft), usually above the treeline.  He points out that marmots are vegetarians and may be eating grasses near their dens if they are not in the midst of their 8-month long hibernation.
