Snowpack Summary

Moderate to strong northeast outflow wind has heavily impacted the snow surface in exposed terrain. In sheltered terrain 20 to 40 cm of snow overlies a layer of facets and a crust from late January. Surface hoar may also be found at this interface.

A layer of facets and crust from early December is buried approximately 60 to 120 cm deep.

Terrain and Travel Advice

  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
