    The recent snow is overlying a layer of weak, sugary facets and in spots, surface hoar. It's taking longer than usual to heal and needs more time.

Avalanche Summary

On Wednesday a skier remotely triggered a size 2 slab avalanche from 80 metres away on a layer of facets and surface hoar over a crust down 90 cm. Southeast aspect at treeline.

A mix of natural, skier-triggered, and explosive-triggered storm or wind slab avalanches have been reported over the last 5 days. Avalanches were sized 1 to 2, generally all in the upper 40 cm of snow and on various aspects and elevations.

Snowpack Summary

The upper snowpack continues to settle and bond. Moist snow surfaces exist below treeline.

Below the recent snow accumulations, down roughly 30 to 50 cm, is a layer of old wind-affected surfaces and weak faceted grains.

Currently, the mid and lower snowpack is generally well-bonded, featuring a thick crust near its base.
