Chipmunk (need to work out which species in due course...)
Yellow-bellied Marmot - a pair of these had apparently made a rather chic home for themselves along the inside of a concrete crash barrier, which conveniently had marmot-sized holes every metre or so!
Columbian Ground Squirrel - pretty common, and very loud!
Elk - a small group of these were feeding on the roadside just outside Jasper, early one morning.
White-tailed Deer - near the western extreme of their range in SE British Columbia
