At Yosemite National Park in California, there's amazing rock climbing. One rock in particular, El Capitan, is known for being a particularly difficult climb. But Kevin Jorgeson and Tommy Caldwell pulled off an incredible feat: not only did they scale El Capitan, but they did it only using their hands and feet.
El Capitan is much loved by rock climbers and BASE jumpers for its challenging face.
While ropes ensure the climbers' safety, they climbed to the top of this 3,000-foot granite formation without using the ropes or any other tools.
They used light sources on their foreheads to illuminate the way at night.
Narrow crevices and fissures in the rock give them openings to use as hand and foot holds.
Ouch, ouch, ouch.
But the climbers couldn't be stopped. They taped their abused fingers and kept at it.
Ledges installed on the side of the mountain give a night's rest that's not for the faint of heart.
Occasionally they found a resting spot to wedge themselves against the rock and take a breather.
Although very necessary, establishing the pitch points for the ropes was a huge challenge.
Night climbing was often preferable to escape the harsh rays of the California sun beaming down on them and glaring back from the face of the rock.
Sometimes they had to set up their tent and take a rest to let their bodies heal.
If you have ever been rock climbing, you know the level of physical activity and muscle soreness that comes even after a few hours of climbing.

You need to make sure you don't have a fear of heights before taking on this climb.
The climb goes high enough that it's not uncommon to see the clouds drifting by.
Through the bloody knuckles, bruises, sore fingers and burning limbs, Tommy Caldwell and Kevin Jorgeson made history by completing the first free ascent of El Capitan's infamously difficult Dawn Wall.
