This view of the Colorado River in lower Cataract Canyon is probably near the Second Expedition's campsite near Clearwater Creek in a section of Cataract Canyon just north of Dark Canyon. Note the abundance of driftwood trapped in the rocks during high water in the foreground. Today, Lake Powell has inundated the canyon for 30 miles upstream from the mouth of the Dirty Devil River (near Hite) to near this vicinity during the highest standing water during years of heavy spring runoff. Initial dam specifications set the high-water level at 3,710 feet, but it was lowered slightly to help prevent inundation of Rainbow Bridge National Monument.
