One person was buried under snow by an avalanche near Nordegg, at the foot of the Alberta Rockies, the Royal Canadian Mounted Police (RCMP) said.
Staff Sergeant John Spaans reported that this person was conscious and breathing, but no other details about his health status have filtered.
Police received an emergency call at approximately 2:00 pm (local time) reporting an avalanche affecting four people on Mount Kitty Hawk.
The RCMP was told that a person dropped 200 to 300 meters along what they describe as an ice climbing route. Doubt persists as to whether it was the person buried under the snow.
The security forces were dispatched to the scene and asked for help from a rescue helicopter.
The air ambulance service also reported on Twitter that it was intervening in the area.
Avalanche risks in Alberta parks were “considerable” Saturday, according to the Parks Canada website. The hazard level is considered dangerous and requires “conservative decision-making.”
