<p>The Great Gallery, in Horseshoe Canyon, Utah, contains rock art that may be 8,000 years old. The seven-foot-high petroglyphs were shown briefly in the movie "127 Hours". The photo here is a composite; the alcove is about a mile up canyon from the art and on the same side of the canyon. I merged them here to increase the feeling of the natural setting.

This remote area is near where Aron Ralston got trapped in a slot canyon and had to cut his arm off after five days. He walked out past these ancient walls.
