Boy, 9, youngest to climb Argentinean mountain

A nine-year-old boy has become the youngest person in recorded history to reach the summit of Argentina’s Aconcagua mountain, which at 22,841 feet is the tallest peak in the Western and Southern hemispheres.

Tyler Armstrong – of Yorba Linda in Southern California in the US – reached the summit on Christmas Eve with his father Kevin and a Tibetan sherpa, Lhawang Dhondup, his team says.
