A bright sunlit canyon wall reflects in water flowing down a small restored waterfall along Fifty Mile Gulch at a location 30 feet below the high-water mark of Lake Powell. This waterfall has only recently emerged into the light of day after being smothered beneath a 30-foot deep layer of Lake Powell sediment. When the waters of the Colorado River backed up behind Glen Canyon Dam beginning in 1963, they quickly invaded this canyon. As silt-laded floodwaters roared down from above and deposited their load of sediment into the stagnant waters of the reservoir here, they eventually buried this waterfall in a layer of mud 30 feet deep. As the water level of the reservoir dropped due to the drought which began in 1999, this accumulated sediment was flushed away by more recent flash floods, all the way down to the pre-reservoir bedrock, thus restoring this small waterfall.
