Avalanche Summary
A MIN report from Mt Rohr (Duffey Lake area) indicated a size 3 slab avalanche in unsupported alpine terrain which likely failed during the storm on the weekend. No other recent avalanche activity was noted. If you've been out in the mountains, we'd love to hear from you. Please share your observations on our Mountain Information Network.
Snowpack Summary
40-50cm of snow from last weekend's storm was shifted by strong winds into much deeper deposits in high elevation lee terrain. In the Coquihalla area, reports suggest weak surface hoar may exist below the recent storm snow, although there is some uncertainty as to its distribution and reactivity. This interface may be something to keep an eye on as the overlying slab gets deeper and gains cohesion.You'll likely find a hard rain crust buried approximately 100cm below the surface. This rain crust extends up to about 2000m.
