Avalanche Summary
No recent avalanche activity has been reported. Please post your observations to the Mountain Information Network (MIN) this weekend.
Snowpack Summary
We currently have very limited snowpack observations, but expect an average snow depth of 70-120 cm in the alpine. This decreases dramatically with elevation where the primary hazards are rocks, stumps, and open creeks.There were reports of feathery surface hoar growing on the surface last weekend in the neighboring Northwest Inland region (see this MIN report) and in Ningunsaw to the north. However, recent outflow winds have likely changed the snow surface conditions and formed stiff wind slabs in open terrain. A hard crust has been reported 10-15 cm below the surface, and in some locations there is an early season crust with facets near the bottom of the snowpack. Check out the MIN report from the Anderson Cabin near Terrace (here).
