@coreyrichproductions All eyes are on El Cap this week as Tommy Caldwell (@トミー・コールドウェル) and Kevin Jorgeson @kjorgeson attempt the hardest, longest free climb in the world: the #DawnWall
of El Capitan, in #Yosemite
National Park, California. Today is their 12th day of living on wall, and they’re just over halfway up the 3,000-foot granite cliff. What makes the Dawn Wall so difficult is that you have to grab edges of rock as thin and sharp as razor blades. In general, climbers find colder rock much more conducive to success. Fingertips sweat less. Shoe rubber has more friction. This explains why they have chosen winter to complete their ascent. Yet even in the dead of winter, it’s still too hot to climb in the direct sun. The climbers have been waiting until dark, when temperature drops to 30 degrees, to attempt the hardest moves. Here, Kevin Jorgeson fights to support his entire body on the tiniest, most painful edges of rock imaginable. You can just see the emotion of the experience in his face.
