El Capitan
I'm not sure why, but Tommy Caldwell and Kevin Jorgeson's record breaking - or record making, rather - free-climb of the sheer face of El Capitan has amazed me. I'm not a climber, but there's something about the scale of this feat that just leaves me in awe. I can't imagine a better place to climb. Yosemite National Park is probably one of the most beautiful places in America, and no doubt served as the ultimate scenery during the 19 days it took the two men to make the summit. I'm not going to bombard you with climbing facts (I don't know any), but I will bombard you with photos from the climb, because they're incredible. They are, in the very literal sense of the word, awesome.
