Daredevil Nik Wallenda crosses a tightrope 1,500 feet above the Little Colorado River Gorge, Ariz., on Sunday, June 23, 2013, on the Navajo Nation outside the boundaries of Grand Canyon National Park. In a February 8, 2014 interview, Wallenda said he hopes to cross the Tallulah Gorge in the northeast Georgia mountains in the near future, as his great-grandfather, Karl Wallenda, did in 1970.
