Living in Calgary, we have seen most of the viewable lakes in the Rockies. Moraine is only easily accessibe in the Summer, and the parking lot can get very busy. In the Winter, it's about a 14km cross country ski. This lake used to be on the Canadian $20 bill. It's certinaly my favorite. Take the small hike up the hill off the parking lot, the views from the top are breathtaking!
