    There is a faceted crust that exists in the lower snowpack. Although no recent avalanches have been reported on this layer, triggering seems most likely on unsupported terrain at higher elevations or within start zones with smooth ground cover.

    Although last week's snow has had time to gain strength, triggering storm/wind slabs may still be possible, particularly in steep, unsupported terrain.

Snowpack Summary

Last week's storm/wind slabs have most likely gained considerable strength with the break in the weather over the past few days. In some parts of the region an early November rain crust sits near the bottom of the snowpack.  Where it exists, this crust has been seen from 1700 m to ridgetop on all aspects. Some tests have resulted in CTM-H ranges with sudden planar characteristics. I have also received reports of a SH layer buried up to 100 cm down. Tests on this layer are in the hard range with sudden planar characteristic. At this time the surface hoar may be specific to certain parts of the region.   Be a detective. Dig down and see how the snowpack is shaping-up in your neck of the woods.
