Today Parks Canada responded to a group of climbers that were hit by a falling tree at the Outhouse Wall at the Back of the Lake climbing area at Lake Louise. High winds likely toppled the brittle snag. It fell 80 to 100m. The tree impacted the group of climbers standing at the bottom and critically injured one climber, while two others had moderate injuries.

ACMG Mountain Guide Mike Stuart was in the immediate area and took decisive action in providing emergency care and assisting Parks Canada with the response. Thank you Mike.

The area is NOT closed. There is no 'hang-fire' or residual hazard left from the tree that fell. However, a flight after the fact indicated that there are dozens of dead trees above climbing area, specifically the Outhouse Wall. This risk will always exist at this popular location. Always wearing a helmet and considering leaving the area in periods of high winds are ways to reduce your risk.
