Two US free climbers reached the top of an iconic rock formation in Yosemite National Park on Wednesday, after spending nearly three weeks inching up a sheer 2,950-foot-high cliff face. Tommy Caldwell and Kevin Jorgeson began their record-breaking climb up the Dawn Wall of El Capitan, a massive rock face seen by millions of tourists every year, in late December.

They have slept suspended in bivouac-style tents attached to the rock, which towers above Yosemite Valley and is some three times as big as France's Eiffel Tower and even bigger than world's tallest building, the Burj Khalifa in Dubai. "This is not an effort to conquer. It's about realizing a dream," Jorgeson tweeted on Tuesday, ahead of the final push.

Caldwell's wife and Jorgeson's girlfriend hugged them as they were sprayed with champagne, local media reported. http://news.discovery.com/adventure/extreme-sports/pair-scale-dawn-wall-most-difficult-rock-climb-ever-150115.htm#mkcpgn=rssnws1
