Avalanche Summary

Not much was reported on Wednesday, apart from a small skier-triggered storm slab. A few loose moist size 1 avalanches were also observed in steep sunny terrain.A skier-triggered size 2 storm slab was reported on a south-west aspect at treeline on Tuesday.

Snowpack Summary

Up to 40 cm settled snow from last weekend overlies variable surfaces including a hard crust which exists on all aspects below 1900 m, and on sunny aspects higher up. On higher, shady aspects, the new snow may sit on some old wind slabs or a mix of large surface hoar and surface facets. Some professionals are still monitoring a deeper crust/surface hoar weak layer about 1 m down. Deeper weak layers are generally considered dormant.
