- Red Flags
- Recent Avalanches, Poor Snowpack Structure

We went out with the intention to look at 2 avalanches, Two Dogs (November 28th), Davenport Hill (November 27th), and stumbled across a third, Silver Fork Headwall (November 29th). The similarities were that all of these avalanches were on north facing slopes and failed on facets. The Davenport Hill slide was a repeater avalanche that had a much thinner crown. The Two Dogs avalanche involved crusts and wind slab and was stiffer than the other 2 avalanches. The Silver Fork Headwall avalanche had no crusts or wind drifted snow in the crown profile.
The crown profiles are below:

Snowpack
North facing slopes were soft snow with some recent surface faceting. Southerly aspects were firm in the morning and softened up in the afternoon. Still lots of summer surface and wildflowers showing through.
