Quick report

We did not observe any natural avalanches from the small storm over the weekend (12/8-12/9). Snow near the ground on shaded slopes remains weak, but the overlying slab has also weakened, decreasing its ability to propagate a fracture. 

No obvious signs of instability. We did not directly observe obviously wind-loaded terrain.

Snowpack

We observed middle elevation snow depths of 55 to 85 cm. Of note, because this area had a deeper, early-season snowpack before mid-November storms, the rain layer from those ARs is 50 cm off the ground, providing a well-connected, stout sliding surface at middle elevations. The 35 cm of snow above the crust is heavily faceted and weak. 

 

Avalanche

No obvious fresh wind slab avalanches from the weekend's light snow + wind.
