Swiss tightrope walker Freddy Nock takes the scenic route to the cable car station on the summit of Diavolezza, or She Devil, a mountain in Switzerland's Upper Engadin region, on August 23. The summit is 9,770 feet (2,978 meters) above sea level.
Nock attempted to set seven world records in seven days with high-wire stunts in Germany, Austria, and Switzerland. The effort failed when high winds forced him to abandon a crossing of Switzerland's Lake Thun on August 27, according to the UPI news service.

Why We Love It
"This picture breaks a few compositional rules, such as 'don't center the horizon' or 'don't include too much empty sky,' to great effect: The tightrope walker pops out of the background and into our amygdalae."—Chris Combs, news photo editor
"The choice to photograph this scene as a vertical emphasizes the space between the tightrope walker and the ground below-and the daring nature of this feat."—Alexa Keefe, photography producer
