Parks Canada is asking anyone who is missing a loved one and could have been in the vicinity of Bow Glacier Falls west of the Icefields Parkway, to contact them.

There was a serious rock fall at 1 p.m. Thursday approximately 37 kilometres north of Lake Louise in Banff National Park. Video posted online shows a large shelf of stone crashing down a mountainside.

RCMP have confirmed that one person was located deceased at the scene. Two individuals were evacuated by STARS Air Ambulance and one by ground ambulance, and their conditions are unknown at this time. The search will continue today to confirm that no other hikers remain missing. RCMP and Parks Canada visitor safety teams from Banff and Jasper national parks responded with support from the Lake Louise Fire Department, STARS Air Ambulance and other agencies.

Bow Lake is closed to all visitors. A NOTAM (no-fly zone) is in place to ensure public safety and for park operations. Banff National Park remains open and safe to visit.
