Grand Canyon vs. Tatshenshini–Alsek: two legendary river journeys shaped by desert and ice. Discover how each delivers a completely different wilderness experience.

The Colorado River below Glen Canyon Dam flows through the lower reaches of Glen Canyon on its way to Lees Ferry , forming one of the most studied and discussed stretches of river in the American Southwest.
