The Maligne Canyon, about three miles from the town of Jasper in Alberta, Canada, is a narrow, very deep gorge, carved out by melting ice and eroding limestone. The gorge is much deeper than my picture shows... in places and one can look over the edge 165ft (50 m) straight down. Except for winter, waterfalls flow over the rocks and the river blow creating a noisy roar heard throughout the gorge. Today the preserved canyon can be viewed by walking a set of trails with six bridges over the gorge during the 1.68 miles (3k) hike. Fossilized sea creatures remain frozen in the rock and cave formations are visible from the trails.
