Multiple people are feared dead after a horrific rockslide swept up numerous hikers who had been enjoying Canada's Banff National Park.
The rockfall, north of Lake Louise, was triggered near Bow Glacier Falls at around 1:30pm on Thursday and 'multiple hikers' were caught in it, said the Lake Louise Royal Canadian Mounted Police (RCMP).
A joint statement by RCMP and Parks Canada confirmed one person died at the scene, and three others were evacuated to the hospital. Their conditions have not been shared at this time.
The Shock Trauma Air Rescue Service (STARS) dispatched two helicopters and transported each patient one by one to Foothills Medical Centre in Calgary.
Video posted online of the incident showed a large shelf of stone rocketing down a mountainside, which then caused a huge cloud of gray dust to rise into the air.
