Lake Powell and Grand Canyon, USA – July 18th, 201037.4N 110.5W
Lake Powell is a reservoir on the Colorado River, straddling the border between Utah and Arizona. It can be seen at the center of this image as a dark blue area surrounded by rose colored terrain.
It is the second largest man-made reservoir in the United States behind Lake Mead, storing 24,322,000 acre feet (30 km³) of water when full. Lake Powell was created by the flooding of Glen Canyon by the controversial Glen Canyon Dam.
Upon opening the full image, another canyon can be seen in the lower left quadrant, extending westward from the western extreme of Lake Powell. This is the Grand Canyon, with the Colorado River flowing through the center.
