Avalanche Summary
No new avalanches were reported on Monday or Tuesday (at time of publishing).
On Sunday, several size 1 to 1.5 slab avalanches were triggered by skiers and explosives and numerous size 1 wet loose avalanches were observed on steep solar slopes.
Snowpack Summary
5 to 15 cm of dry snow sits atop melt-freeze layers. Several crusts may be found anywhere from 0 to 40 cm deep, depending on aspect and elevation.
The facet/crust layer that caused large avalanches in March is buried 100 to 150 cm deep and is unlikely to trigger under the current conditions.
