Grand Canyon West is privately owned by the Hualapai tribe, and it was they who conceived of and now operate the Grand Canyon Skywalk -- A transparent, horseshoe-shaped cantilever bridge in Arizona that allows you to get a feel for just how gigantic the Grand Canyon truly is, by scaring the life out of you.
