The water-sculpted sandstone bowl in this photograph is at an elevation 75 feet below the high-water mark of Lake Powell. When the reservoir was last full in 1999, its sediment layer smothered this small canyon to depth of 10 feet. As the water level of the reservoir began to drop due to the regional drought which began in the year 2000, this layer of accumulated sediment was eventually washed away by flash floods, all the way down to the pre-reservoir streambed. Native Willow and other plants have quickly reclaimed the floor of this well-watered canyon now that the waters of Lake Powell have receded. Glen Canyon National Recreation Area, Utah.
