Footage released by British Columbia Transportation gives a panoramic view of explosives triggering a controlled avalanche on Morrissey Ridge near Fernie on April 26.

BC Transportation said the controlled explosion prompted snow deposits to come within 100 meters of a nearby highway, which was closed at the time.

The safety procedure follows two fatal skiing incidents in the area in January.
