Avalanche Summary
On Tuesday explosive control in the region triggered numerous wind slab avalanches up to size 2. These avalanches were on south and southeast aspects at treeline and in the alpine. A few of them ran on the crust described in the snowpack summary.
Snowpack Summary
Snow at higher elevations is heavily wind effected, with deeper deposits on east facing slopes, and west facing slopes may be scoured. Wind slabs may sit over a crust, hard wind affected surfaces or surface facets (weak crystals).
A melt freeze crust exists near the base of the snowpack, reports suggest it is currently not a problem for the region.
Treeline snow depths are typically 50 to 80 cm, with deeper wind-loaded pockets in the alpine.
