Permian- and Triassic-age sedimentary rocks color the shorelines of dam-impounded Lake Powell near the confluence of the Colorado and Dirty Devil Rivers. Although the lake water has submerged numerous relicts of ancient animal (including human) and plant life, traces of prehistoric life can still be found along the lake shores and in some tributaries.
