Avalanche Summary
On Saturday a skier accidentally triggered a large avalanche near Hudson Bay Mountain. It is suspected that this avalanche failed on the facet/crust combination described in our snowpack summary. Check this MIN post for full details.
Snowpack Summary
In general, up to 10 cm of soft, faceted snow overlies hard, wind-affected snow in alpine terrain. Wind-exposed terrain may be scoured down to hard surfaces, while a sun crust exists on south-facing slopes.
In steep, exposed alpine terrain, old, hard wind slabs may sit atop weak faceted crystals and a crust, down roughly 20 to 30 cm from the surface.
The mid and lower snowpack is generally well-bonded and strong.
