Snowpack Summary
A variable snow surface generally includes up to 5 cm of soft snow on a supportive crust with surface hoar or surface facets, breaking down to corn snow on all but high north aspects with daytime warming and sun-exposure. Wind slabs may be found in the alpine, or lower in glaciated drainages from katabatic winds. But in general, the snowpack is strong.
Problems
Wind Slabs
Thin, old, hard wind slabs may be lurking on lee and cross-loaded alpine terrain, and fresher ones from recent gusty northwesterly winds. Cornices are also large, undermined, and weak, and could be strained by rapid cooling.
Be cautious as you transition into wind affected terrain.>Give cornices a wide berth when travelling on or below ridges.>
Aspects: All aspects.
