Lo esencial

Assess terrain carefully and practice good group management

The best riding may be on the same features where triggering an avalanche is most likely

Problemas de aludes

  • Wind Slabs

    Small, rider triggerable wind slabs may still be found at higher elevations.

  • Persistent Slabs

    This layer remains a concern in high terrain where the snowpack depth is variable or a cornice hangs above the slope.

Confidence

Moderate

Avalanche Summary

We have not received reports of slab avalanches since last week but observations in this region are limited.

Snowpack Summary

A new crust likely exists on the surface except on high north facing terrain, where up to 20 cm of snow overlies a crust from earlier in March.

A layer of facets and surface hoar from late January can be found down 50 to 120 cm.

The lower snowpack contain several crusts that are not concerning.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
