About Tommy Caldwell:
Tommy Caldwell is an American rock climber. He is accomplished in several types of climbing, including sport climbing, hard traditional climbing, big-wall speed climbing and big-wall free climbing. He made the first ascents (FA) of some of the United States' hardest sport routes (as of 2008) including Kryptonite (5.14c/d) and Flex Luthor (a possible 5.15a) at the Fortress of Solitude, Colorado. In January 2015, Caldwell and Kevin Jorgeson completed the first-ever free climb of the Dawn Wall of El Capitan in Yosemite National Park. It was documented by photos and journalistically by Tom Evans (see El Capitan).
