Grand Canyon Skywalk

I think that the Grand Canyon Skywalk is one of the most amazing things made by man. The Grand Canyon Skywalk is a tourist attraction along the Colorado River on the edge of the Grand Canyon in the U.S. state of Arizona.

It is a horseshoe-shaped glass walkway that stands at a 3,600 feet height above the floor of the canyon, a height exceeding those of the world's tallest skyscrapers. The Skywalk is not directly above the main canyon, Granite Gorge, which contains the Colorado River. Instead it extends over a side canyon and affords a view into the main canyon.

This is a great video I found on Youtube that shows you the spectacular view that the Skywalk has, and the shape of the Skywalk.
