Snowpack Summary

Small pockets of stiff wind slab have formed at higher elevations in response to light amounts of new snow and strong southwest wind. In areas protected from the sun the new snow may overlie surface hoar at treeline elevation. Several crusts can be found in the snowpack, especially on solar aspects; however, reports indicate these interfaces have settled out fairly rapidly. The mid and lower snowpack layers are generally strong and well settled. Total snow depths vary from around 400 cm in the south to around 180 cm in the north.

Problems

Wind Slabs

Strong winds have built small yet stiff wind slabs behind ridges and ribs in exposed areas.
