A hiker is recovering in hospital after tumbling nearly 45 meters(150 feet) from a scree slope on Sunday.
The 35-year-old woman was hiking with six others on Mount Haig, west of Castle Mountain ski resort, when she fell.
RCMP were alerted to the trouble just after 3:15 p.m., when an emergency beacon was activated.
Several agencies, including Waterton National Park public safety, Kananaskis Provincial Park public safety and Banff National Park helped to locate the group of hikers.
However, bad weather prevented crews from rescuing the injured hiker.
A public safety officer set up a survival tent and stayed with the woman overnight, until she could be safely airlifted off the mountain.
“This was one of the largest rescue efforts I have been a part of,” said Cpl. Jeff Feist, with Pincher Creek RCMP. “Saving this woman’s life can be credited to the superior technical ability of all those who participated in this extremely complex mission.”
RCMP say the woman has serious injuries and is being treated at a hospital in Calgary.
