These observations document past conditions at a small and variable scale. They are not to be confused with an avalanche forecast. They come from a variety of sources. We can only vouch for the quality of those produced by the SAC forecasters and professional observers.

Kicking at the uphill side of the skin track yielded storm slab cracking at 8,400 feet. ECTN12 20cm down at the bottom of the dense storm slab. N aspect at 9,100 feet. CT8 at the same storm slab layer as the ECTN. This compression test also broke CT24 Q2 at the top of the crust sandwich layer in the old snow Public

New storm slab cracking on slope undercut by skin track. Flipping my ski pole upside down, the snow was quite resistant initially in the firm storm slab. Once through the storm slab, the snow was very soft for the rest of the length of my ski pole. Tree rings demonstrating snow settlement due to warming. Hand hardness overview of new snow. One finger hard slab, over fist hard storm snow. Professional Observer
