Tommy Caldwell, left, and Kevin Jorgeson near the summit of El Capitan Wednesday, Jan. 14, 2015, as seen from the valley floor in Yosemite National Park, Calif. The two climbers vying to become the first in the world to use only their hands and feet to scale a sheer granite face in California's Yosemite National Park are almost to the top. Jorgeson and Caldwell have been attempting what many thought impossible. The men have been "free-climbing" to the 3,000-foot summit for 17 days, meaning they don't use climbing aids other than ropes only to prevent deadly falls. Each trained for more than five years, and they have battled bloodied fingers and unseasonably warm weather. (AP Photo/Ben Margot), APTOPIX
