Snowpack Summary
Total snowpack depths range from 110 to 160cm at treeline across the region. On the surface a newly developing storm slab covers a variety of old surfaces which include: old wind slabs at higher elevations, melt-freeze crusts on previously sun-exposed slopes and surface hoar in shaded terrain.In the mid snowpack you may find a layer of surface hoar buried in mid-November ranging from 50-90cms in depth. An October crust/facet combo exists near the base of the snowpack. These persistent layers are slowly becoming more difficult to trigger. However, they have the potential to cause large and destructive avalanches, and may 'wake-up' with the increased load of new snow forecast for the next few days.
