ANCHORAGE, Alaska - The National Park Service says an American climber has died on Mount McKinley.

The agency says a helicopter crew Wednesday night spotted the remains of 39-year-old Sylvia Montag, who had been climbing with 34-year-old Mike Fuchs of Berlin, Germany.

The two were some of the earliest trying to scale the 20,322-foot (6,194-meter) peak, North America's tallest, this climbing season.

The park service says the pair began their ascent April 15 and on Saturday reached Denali Pass at 18,200 feet (5,550 metres).

Strong winds forced them to camp for two nights.

Fuchs called rangers Monday and said they had separated as they tried to descend to 17,200 feet (5,240 metres).
