Avalanche Summary
Since Sunday there have been steady reports of size 1 (and some size 2) natural and human triggered slab avalanches. These have occurred on a variety of aspects at treeline and alpine elevations, with some avalanches failing on surface hoar and running on crusts.
Snowpack Summary
Sun and wind are creating variable surface conditions. Exposed terrain is being scoured by northeast wind and forming small wind slabs on south and west facing slopes. Roughly 30 cm of snow sits above large surface hoar and/or faceted crystals in wind-sheltered terrain at treeline and above.
A widespread, supportive crust exists 30 to 40 cm below the surface. The snowpack is strong and bonded below this crust.
