Mistaya Canyon
A deep, narrow channel cut by post-glacial river erosion.
via Wikipedia: Mistaya Canyon · see source
Tucked along the Icefields Parkway in Banff National Park, Mistaya Canyon is a narrow, deep channel carved by the Mistaya River. This roadside stop in Alberta’s Canadian Rockies is reached by a short walking trail from a nearby parking lot. The canyon sits near where the Mistaya meets the North Saskatchewan River. The surrounding mountains show clear signs of ancient glaciation, and the canyon itself was formed after the glaciers retreated, as the river eroded the rock. The steep walls are made of limestone and dolostone, with fractures and bedding planes guiding the erosion that created the canyon’s tight profile and potholes.

Background
The canyon occupies part of a glacially modified valley system that was subsequently re-incised by modern river flow following deglaciation. Structural features such as fractures and bedding planes locally guide erosion, contributing to the canyon’s narrow profile, steep walls, and the formation of potholes. The Mistaya River ultimately flows into the North Saskatchewan River a short distance downstream.
Did You Know?
- The canyon was cut by post-glacial river erosion into Paleozoic carbonate rocks.
- The surrounding landscape is mountainous and heavily influenced by past glaciation.
