Visit the surreal world of shifting ice at the Columbia Icefield. Join a guided Athabasca Glacier Icewalk or Ice Explorer tour, or simply stroll the short Toe of the Glacier Interpretive Trail. If you’re walking the walk, you should talk the talk:
- Till: Sediment rock deposited during glacial melting.
- Lateral Moraine: Till along sides of an abating glacier.
- Terminus: End of the glacier; also called the glacier snout.
- Moulin: Deep hole carved by flowing surface water.
- Crevasse: Crack formed by ice segments moving at different rates.
- Serac: Jagged tower of ice formed by colliding crevasses.
