Two US climbers became the first to scale the 3,000-foot Dawn Wall of Yosemite's El Capitan, using only their hands and feet.
Kevin Jorgeson, from Santa Rosa, California, and Tommy Caldwell from Estes Park, Colorado became the first to "free-climb" and reach the top of the summit, reported BBC News.
They began their historic half-mile ascent on 27 December. During the climb the pair reportedly slept in tents suspended from the mountain face.
Caldwell finished the climb first and Jorgeson caught up minutes later.
Caldwell's mom said, "He's finally reached his dream. This is something that he never thought would happen."
Kevin Jorgeson's father, told local media that watching his son fulfil a long-time dream has made him proud.
"He climbed everything he could think of. It made us nervous early on as parents, but we got used to it," he said.
"I feel like the most proud person in the world right now," Caldwell's sister, Sandy Van Nieuwenhuyzen, said.
President Barack Obama has congratulated the pair on Twitter.
