Jay and his fellow skier were on Mount Saint Helens in Washington State, where they noticed unstable conditions throughout the day.
The pair then managed to trigger a small avalanche, all of which was caught on film.

The skier in the footage can be seen treading across the snow briefly before a wedge of the powder slips away from him.
Luckily the man manages to keep his balance, remain upright and avoid slipping down the mountain with the snow.
Jay, who posted the video on YouTube, estimates the avalanche left a gap of up to 18 inches deep and 50 feet across in the snow.
