Two climbers made history this week when they became the first people to free-climb the Dawn Wall on El Capitan in California’s Yosemite National Park. Considered one of the most challenging climbs in the world, the Dawn Wall is roughly 3,000 feet (914 m) of sheer granite rock face. Making the ascent even more difficult was that Tommy Caldwell, 36, and Kevin Jorgesen, 30, free-climbed. That means their ropes were there only to prevent them from falling, not to help them. The entire journey took an amazing 18 days.
