Columbia Icefield Deep Dive
The Columbia Icefield in the Canadian Rockies straddles the boundary between Banff and Jasper national parks. It is the largest icefield in the Rockies south of the Arctic Circle — about 230 km² of ice feeding eight major glaciers, including the Athabasca, Saskatchewan and Columbia. From the icefield, meltwater flows to the Arctic, Atlantic and Pacific oceans, making it the hydrological apex of North America.
Geography
The icefield sits at around 2,800 to 3,500 m elevation on the spine of the Rockies. The Columbia Icefield Discovery Centre on the Icefields Parkway, between Lake Louise and Jasper, is one of the most visited interpretive centres in Canada — and the Athabasca Glacier's snout is a short walk from the parkway.
The Athabasca Glacier
The most visited glacier toe in North America. Day visitors can walk to a viewing area near the snout; "Ice Explorer" snow coaches take groups onto the lower glacier; guided crampon walks go further up. The toe has retreated about 1.5 km since the 1840s, and the rate is accelerating.
The Columbia Glacier (Canada)
Not to be confused with the Columbia in Alaska. Drains north from the icefield to feed the headwaters of the Athabasca and Saskatchewan rivers. Less visited than Athabasca; mostly seen on ski mountaineering traverses across the icefield.
The Saskatchewan Glacier
The longest outlet of the Columbia Icefield, about 13 km. Visible from various points along the Icefields Parkway between Lake Louise and the Saskatchewan River Crossing.
Mass balance and change
All Columbia outlets are losing mass rapidly. The Athabasca tongue is thinning by about 1.5 m per year on average. The Saskatchewan has retreated about 1.5 km from its 1900 extent. The whole icefield could lose most of its volume by the end of the century under current trajectories.
Activities
- Boardwalk / Toe of the Athabasca. Free, signed, takes about 30 minutes round-trip from the parking area.
- Ice Explorer. Specialised snow-coach trip onto the lower glacier; the only "drive on a glacier" tourist experience in Canada.
- Glacier Skywalk. Cantilevered glass walkway over the Sunwapta valley near the Discovery Centre.
- Guided ice walks. Half-day outings on the lower Athabasca with local guide companies; crampons provided.
- Ski traverses. The Wapta-Columbia traverse is the classic ski mountaineering circuit, hut-to-hut over the icefield's upper plateau.
When to visit
The boardwalk and snow-coach operations run from mid-April to mid-October. Winter access is limited; the parkway sometimes closes for avalanche control.
