Avalanche Summary
Several small (size 1 to 1.5) storm slabs were triggered near Fernie on Saturday.
Snowpack Summary
Up to 15 cm of new snow fell accompanied by strong southwest wind forming larger deposits on north and east aspects. In sheltered terrain, this new snow could overlie surface hoar.
Another layer of surface hoar and/or crust can be found down 20 to 40 cm. Where this crust is thin or not present a layer of surface hoar may be found.
Check out this MIN from the Purcell side of this region and this one from the Fernie area.
The middle of the snowpack is generally expected to be well-settled and stable. Total snow depths vary from 100 to 150 cm at treeline.
