Being landlocked, the Canadian Rockies are not renowned for scuba diving. A few interesting opportunities do exist, however, and rentals are available in Lethbridge, Calgary, and Edmonton. The old town site of Minnewanka Landing, in Banff National Park, has been flooded, and although a relatively deep dive, the site is interesting.
Patricia Lake, in Jasper National Park, conceals a sunken barge that Winston Churchill had built as an aircraft carrier that was also capable of functioning as an icebreaker, and due to the high altitude and clear water, visibility is exceptional.
Another sunken boat lies at the bottom of Emerald Bay in Waterton Lakes National Park, not far from some wagons that fell through the ice many winters ago. For a list of dive shops and sites, contact the Alberta Underwater Council (780/427-9125 or 888/307-8566, www.albertaunderwatercouncil.com).
