This demonstrates the retreat of the glacier as it melts, and leaves a powerful impression.

forefield trail

The forefield trail passes through an area that, less than 100 years ago, lay beneath the glacial ice. From the trail there are excellent views of the Athabasca Glacier and the landscape it has sculptured.

Sturdy shoes and a jacket are recommended for crossing this rocky, breezy terrain.

The few plants that have gained a foothold here live a harsh life. Please help to protect them and the area by staying on the trail."
