Argentina: American climber dies while climbing Aconcagua mountain

A US man died Friday while scaling Argentina's Aconcagua mountain, becoming the fifth climber to perish this month on the highest peak in the Americas, officials said. An army patrol on a training operation came across the man lying on the ground and calling for help in the afternoon after he was apparently hit by falling rock at 5,000 meters, said Julio Suarez, police spokesman in Mendoza province. The man died an hour later as squad members were carrying him down to a base camp. A doctor there confirmed he died of a head injury and a pneumothorax, or collapsed lung, Suarez said.
