Avalanche Summary
No recent avalanches have been reported.
With limited observations this time of year, sharing your photos and observations on the Mountain Information Network helps everyone stay informed.
Snowpack Summary
A dusting of new snow is falling on a well-settled and strong snowpack, with a typical spring diurnal pattern in effect. Daytime warming moistens the upper snowpack, and overnight cooling usually forms a hard crust at higher elevations. Lower elevations may not refreeze and are melting out quickly.

Terrain and Travel Advice
- This is a good time for exploring terrain.
- Travel early on sun-exposed slopes before cornices weaken with daytime warming.
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
