Snowpack Summary

Heavy wet snow combined with rain fell in early November up until the 10th, when the temperatures dropped and the sky cleared. This clear weather came with moderate to high winds from the North which created some wind-slabs which are sitting on top of a crust base. Large plumes of spin drifted snow were observed from ridges on the 11th.

Avalanche Summary

Avalanches up to size 2.5 were observed on Nov 11th some of which were slab avalanches.
