Climbers scale 'impossible' El Capitan

Two adventurers have completed a record breaking free-climb of the El Capitan mountain.

Tommy Caldwell and Kevin Jorgeson have been climbing the Dawn Wall of El Capitan, a rock formation in Yosemite National Park, USA.

It's been described as the most difficult climb in the world, because the face is so steep, so tall, and so smooth.

The two climbers took 19 days to complete it and are the first people to free-climb this route.
