A US park ranger has died after falling into a crevasse on North America's tallest mountain, Denali, the National Park Service has confirmed.
Robin Pendery, a seasonal mountaineering ranger from Enumclaw, Washington, fell on Thursday while on climbing patrol near a camp at 14,000ft (4,328 metres). Despite immediate rescue efforts, she could not be saved.
The death is under investigation. It comes just a week after three climbers from a Latvian expedition died after falling near a treacherous pass on the mountain, also known as Mount McKinley. A fourth climber from that seven-person team was rescued.
Denali superintendent Brooke Merrell said: 'Our mountaineering rangers dedicate themselves to serving visitors and helping others in one of the most challenging environments in the world. Today, we mourn the loss of a valued colleague, friend and teammate.'
Denali, which stands about 20,310ft (6,190 metres) above sea level, is known for its exposed sections and has claimed many lives over the years.
