We saw some two big avalanches today at Bijoux. These large slides (size2.5) appear to have failed on the Feb 8th surface hoar where it has been loaded by wind. The first avalanche appeared snowmobile triggered in a shallow roll but failed as deep as 120cm as it went across. At its steepest point it also stepped down to an older layer in the snowpack reaching 180cm deep. The second avalanche ran almost 450m. It appeared to be triggered by a cornice collapse and had set off additional crowns as it traveled down the track. Be very aware of this reactive layer especially where it is being loaded by winds.

Snow conditions were: Hard, Wind affected. Weather conditions were: Sunny. We rode: Alpine slopes, Open trees. We avoided: Convex slopes. Riding quality was ok.

Avalache Conditions: Slab avalanches today or yesterday.
