July 2011 Earth Science Picture of the Day Viewer's ChoiceUpper Antelope Canyon is one of a number of impressive slot canyons in the high desert of northern Arizona. It's about a quarter mile (0.4 km) long and, in places, less than a few feet wide. At this location, the canyon walls are approximately 33 ft (10 m) high. These narrow, twisted canyons formed over thousands of years as sandstone was eroded during flash floods events.

The above photo is a combination of nine bracketed shots combined in a special program to create high dynamic range images. The color has not been enhanced -- this is what it looked like the day I was there. Depending on the quality and color of the light, the canyon walls can appear in shades of red, gold and tan. By combining as many shots as I did, I was able to capture most all of the shadows and highlights in a given location. Photos taken on May 17, 2010.
