Atop the Grand Canyon

A tourist held her arms up to feel the wind coming up from the Grand Canyon on March 20 as she stood on the Skywalk. She wore cloth booties to keep dirt off of the glass walkway. The $30 million glass-bottomed walkway juts out 70 feet from the rim at an elevation of 4,000 feet above the Colorado River.
