A slackline walker has crossed the Enshi Grand Canyon in China's Hubei Province on a rope just two centimetres thick.
American Dean Potter - who grew up in New Hampshire - crossed a distance of 40m (44 yards) in just over two minutes at a height of 1,800m (1,968 yards) above sea level, according to Chinese state media.
The feat considered more challenging than tightrope walking, as the line is not held completely taut and is susceptible to stretching and bouncing, as the BBC's Karin Giannone explains.
