DENALI NATIONAL PARK AND PRESERVE, Alaska (AP) — A ranger in Alaska died after falling into a crevasse on North America's tallest mountain, the National Park Service said.

Robin Pendery of Enumclaw, Washington was a seasonal mountaineering ranger assigned to Denali National Park and Preserve. She fell Thursday while on climbing patrol on Mount McKinley, and died despite immediate rescue efforts, the park service said.

The death is under investigation. It comes only a week after three climbers from a Latvian mountaineering expedition died after falling near a treacherous pass on McKinley. A fourth climber was rescued. They were part of a seven-person team traversing a route known for its exposed sections, where many climbers have died or been injured over the years.

McKinley stands at about 20,310 feet (6,190 meters), and Pendery fell near what's known as the 14,000-foot (4,328-meter) camp.

“Our mountaineering rangers dedicate themselves to serving visitors and helping others in one of the most challenging environments in the world,” Denali Superintendent Brooke Merrell said in a statement Friday. “Today, we mourn the loss of a valued colleague, friend and teammate.”
