A picture taken with a drone shows a highliner performs during the Highline Extreme event on the top of the Moleson peak at 2000 meters above the sea level, in the Swiss Alps, near Gruyeres, Switzerland, Sept. 15, 2018. Twenty-five of the world’s best slackliners compete from Sept. 13 to 16, on 6 different lines ranging from 45 meters to 480 meters. Balancing on the 'slackline' is a training method for climbers to improve their equilibrium sense. To avoid the danger of falling down, the athlete is secured with a rope. (Photo/Agencies)
