Snowpack Summary

5 to 15 cm of recent snow may be sitting on a crust that exists up to 1850 m in the Wells area. This new snow is likely being redistributed in exposed terrain. An additional 5 to 10 cm is expected to fall on Thursday.

A layer of surface hoar and/or sugary facets may be found sitting around 20 to 40 cm below the snow surface. This layer is most concerning above 1800 m where there is no crust covering it. Additionally, wind slabs forming over this layer in the alpine may be more reactive.

The middle and lower snowpack is generally strong with no weak layers of concern.

Terrain and Travel Advice

  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
