Skier triggered avalanches are still possible in the alpine and open areas near the tree line. Thick-to-thin trigger points and areas where the mid-March crust is not supportive to boots or skis are suspect.

Terrain and Travel Advice
- Closely monitor how the new snow is bonding to the old surface.
- Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
Problems
Persistent Slabs
Thick to thin trigger points and areas where mid March crust is not supportive to boots or skis are a suspect. This problem layer is the crust and facets created by early February's warm spell. It is down 30-90 cm in the snowpack and is a 1-10 cm thick crust with a layer of weak facets above.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Dry
Loose dry avalanches likely won't be much of a hazard unless they push you into or off a terrain trap.
Aspects: All aspects.
Elevations: Alpine.
Likelihood
Expected Size
Deep Persistent Slabs
Basal depth hoar makes up the bottom of the snowpack. This is a low probability but high consequence problem. Stay away from weak, rocky, shallow location where triggering this layer is more likely.
Aspects: All aspects.
Elevations: Alpine, Treeline.
