Over the past few days strong easterly winds have scoured east slopes and created wind slab on south and west facing slopes.
A layer from mid November is buried down around 70cm at treeline. This layer consists of surface hoar, facets and a crust below treeline and on south facing slopes.
The depth of the snowpack at treeline varies from 80-140 cm and tapers rapidly below treeline.
Many early-season hazards such as rocks, stumps, and open creeks exist below treeline.
