Snowpack Summary

The snowpack is mostly stable and will not not change much until we see a major weather change. Quite a bit of wind affect on all aspects in the alpine and trending to treeline.  Isolated sun crust on steep solar aspects. Surface hoar is growing and is found up to 2100m. The November rain crusts will be present for the season and are 30-50cm down from the surface but are not a big concern at the moment.

Problems

Persistent Slabs

An icon showing Persistent Slabs
This layer is widespread in terms of its location in the terrain. Its condition seems to vary from an intact crust to a facetted mish mash of weak grains. Thin areas that have a hard slab over top should be treated with caution.
Be cautious in shallow snowpack areas where triggering is more likely.

Aspects: North, North East, East, South East.
