For the past 10 days, Keven Jorgeson and Tommy Caldwell have been climbing the 3,000-foot sheer granite face of El Capitan. Sure, many climbers have done this before, but these two are different: if they complete their task of free-climbing the Dawn Wall of El Capitan (without anything but safety ropes and their bare hands), they will be the first to do so in 45 years. Their predecessors were Warren “Batso” Harding and Dean Caldwell in 1970, a task that took the two climbers 27 days to overcome. The route they are following up the Dawn Wall has been called the longest and hardest free climb in the world. “Free-climbing” is a term describing a style in which climbers use ropes and gear as safety precautions only. No gear or ropes are used to ascend or support the actual climbing of the wall, as compared to styles of “aid-climbing” where climbers may stand on supports or raise themselves with ropes during the climb. Kevin and Tommy have been up on the wall for over a week now, and seem to be making good progress. In 2010, a previous attempt was foiled by a storm. In 2011, a fall and a broken ankle stopped their progress. But this time, after 6 years of prepping and training, they’ve had clear skies and luck, and the whole world is watching their progress on the news, the web, and even Tommy’s twitter feed! If everything goes well from here on out, they could reach the top as soon as this weekend. Some of our guides and passengers on our Yosemite Day Tours and Yosemite Stay & Play Hotel Tours have reported seeing the climbers hard at work or resting in their tents on the side of the wall. Have you seen them?
