In January 2015, Kevin Jorgeson and Tommy Caldwell climbed to the top of the Dawn Wall of

El Capitan – a famous mountain in Yosemite National Park, USA. This is often described as

the world’s most difficult rock climb. It took Jorgeson and Caldwell eighteen days to climb the

900 metres to the top! During this time, they hung tents off the rock, and ate and slept in them.

The Dawn Wall is so difficult because there is nothing big for climbers to hold onto. Jorgeson

and Caldwell had to climb by holding tiny pieces of rocks with the ends of their fingers. They

used ropes to protect themselves from falling, but not to help them climb.

Kevin Jorgeson nearly didn't finish the climb. He found one part of the Dawn Wall extremely

difficult. It took him seven days to do this part, and he fell eleven times. His fingers were

damaged too, so he had to wait for them to get better before he could continue. But in the

end, both men finished the climb together. It was an amazing achievement.

Only two weeks later, an ice climber called Will Gadd became the first person to climb a

frozen part of the Niagara Falls. These falls, on the Niagara River between America and

Canada, are the biggest waterfalls in North America. They are made of three separate

waterfalls, and Gadd climbed the Horseshoe Falls, on the Canadian side. In winter, a part of

these 50.9 metre falls freezes, and Gadd wanted to climb up the ice. But it was an extremely

difficult climb. The ice was very thick in some places, but not in other places. And because

only a part of the waterfall was frozen, a lot of water fell past Gadd as he climbed. Gadd knew

that if he fell, he would probably die − but he got to the top.

But why do people want to do dangerous climbs like these? 'Dangerous situations are very

exciting,' says climber Terrence Jones. 'They make you feel alive.' Humans have always

looked for challenges, but many of the old challenges – like climbing Mount Everest – aren’t

exciting enough for some climbers because so many people have already done them.

‘Climbers like Caldwell and Gadd want to achieve more than anyone else,’ says Jones, ‘so

that the world will read about them in the papers and see them on TV.’

One day people will complete all of the difficult climbs on Earth, so what will climbers do then?

‘I don’t know,’ says Jones. ‘But perhaps one day far in the future people won’t climb on Earth.

There are still mountains to climb on Mars!’ This may never happen, of course, but one thing

is certain: the search for adventure will not stop.
