Wind River Indian Reservation (permit required for upper sections)
The Wind River carves through Wind River Canyon between Boysen Reservoir and the town of Thermopolis, cutting through 2.5 billion years of geological history. The canyon walls expose some of the oldest rock in North America, and the river delivers Class II–III whitewater framed by towering formations.
