A sudden break in the cliffs prohibits any further travel. Known as the Great Break, this jagged rift separates the southern end of the riverbed from its northern part. Far down at the bottom of the Great Break is a landscape of treetops, and the hint of a small lake. Beyond it, the riverbed continues its winding course into a dusty, far-off horizon.
