Snow conditions were: Hard, Wind affected. We rode: Alpine slopes, Mellow slopes. Riding quality was terrible.

Snowpack

After the avalanche, we did 3 column test in the same snowpit at pretty much the same elevation and aspect. The snowpack wasn't as thick as where the avalanche trigger but the result where as clear and precise. A 50cm of hard windslab(pen..to almost knife) was sitting on a 2inch thick surface hoar layer. The column 30x30 colapse will cutting it. Not even in the need to get your shovel to tap on it. Would call it very easy test result.

Avalanche

Big avalanche trigger by skier will ski cutting on 25to30% slope above the convexity in the jumelle bowl on southern aspect of mont albert the crown was huge from 20 cm up to almost 2 meters. The weak layer was a very big layer of burried surface hoar. The layer was about 2 inch tick. The trigger spot was at 1.2m thick from a rocky ridge (safespot).
