A low avalanche danger rating does not mean letting your guard down. Isolated wind slabs may surprise you.

Carefully assess your slope before committing to high consequence terrain.

Snowpack Summary

The alpine and exposed features are greatly affected by the wind and present a mix of surfaces (soft and hard slabs, sastrugi, ice, pressed snow). In sheltered areas, 10 to 25 cm of low density snow cover the March 18th melt freeze crust, observed at all altitudes. Below 500m, there is a thin melt freeze crust on the surface, due to the mild temperatures of Monday and Tuesday.

On the solar aspects, the short episode of sun on Friday morning could soften the thin melt freeze crust for a couple of hours, but expect it to be still perceptible, because of the forecasted clouds in PM.

The mid-snowpack is well consolidated and right-side up. The base of the snowpack is composed of laminated crusts. In general, the height of the snowpack varies from 90 to 110 cm in the valley to 130 to 180 cm at the treeline.
