If all goes according to plan, on June 23rd daredevil Nik Wallenda will step out on a tightrope 1,500 feet above the Little Colorado River and attempt to cross the Grand Canyon. 

The dangerous stunt, to be broadcast live on the Discovery Channel, will be even more nail biting due to the fact that Wallenda will not be wearing a safety harness. 

“The stakes don’t get much higher than this,” said Wallenda in a statement. “The only thing that stands between me and the bottom of the canyon is a two-inch thick wire. I’m looking forward to showing the audience a view of the canyon they’ve never seen before.” 

The lack of a harness is a big win for Wallenda (at least how he sees it), after being forced by the ABC television network last year to wear one during his record-making tightrope walk over Niagara Falls. That event was a massive ratings win for the network, averaging over 13 million viewers from 10:30pm-11pm. Discovery is, naturally, hoping for a similar result. 

"Discovery Channel continues to bring some of television’s most talked about and historic live events of the year. From Felix Baumgartner setting the world record for highest skydive in Space Jump Live to this latest feat showcasing Nik Wallenda’s greatest challenge yet," said Eileen O’Neill, group president, Discovery and TLC Networks, in a statement.

Wallenda's attempt will take place in a remote section of the canyon operated by the Navajo Nation Parks and Recreation. 
The 34-year-old plans to use the occassion to honor his great-grandfather, the legendary Karl Wallenda, who died after falling from a tightrope in Puerto Rico in 1978.
