WATCH: heart-pounding first free ascent of El Capitan's Dawn Wall

Earlier this month, Tommy Caldwell and Kevin Jorgeson made the first free ascent of El Capitan's 3,000-foot Dawn Wall at Yosemite. This dizzying footage is sure to have your palms sweating.

The Dawn Wall is rated a staggering 5.14c on the Yosemite Decimal System, which means falling will result in severe injury or death. Just reading Tommy's account of the climb sounds like a whole lot of NOPE.

In this insane image, Tommy says:

Some of the smallest and sharpest holds I I have have ever attempted to hold onto. Is crazy to think that the skin on our fingertips could be the limiting fact towards success or failure. I have resorted to setting my alarm to wake myself up every four hours to reapply @climbonproducts

A feature film of the feat is forthcoming.
