Horseshoe Bend Overlook:
This is where one can see the Colorado River meanders back on itself. The sheer cliffs drop 1,000 feet to the river below. The magnitude of this expanse is difficult to appreciate in a photo, but just left of center there is building just above the shoreline that can help provide some perspective. There are not any protective barriers on this cliffs edge, so getting the photo required conquering all acrophobia.
