Eight-year-old boy becomes youngest person to ascend Yosemite’s El Capitan

Sam Adventure Baker went up the cliff with his father, but some climbers say method known as jugging' is not true climbing

An eight-year-old boy has become the youngest person to ascend the terrifying sheer rock wall of El Capitan in America's Yosemite national park, his father said in a Facebook post.

Sam Adventure Baker had been going up the huge cliff with his father since Tuesday. The duo are part of a four-person team, where one person climbs ahead and sets the ropes for others to follow. Nights are spent sleeping on the rock face.
