Avalanche Forecast

A few old wind slabs were reported in the Core Lodge area on Wednesday, which were suspected to have occurred last week. No newer avalanche activity has been reported.

Keep posting your observations to the Mountain Information Network!

Surface snow is predominantly wind-affected, with sastrugi in many open upper-elevation areas. Soft snow may be found in sheltered areas above 1500 m. A new layer of surface hoar and facets may be thinly buried by 1-5 cm of recent snow in sheltered areas.

A second layer of surface hoar may be found around 50 cm deep. It has been producing limited results with snowpack tests. The mid-pack is generally made of weak, sugary faceted crystals, along with a crust near the base of the snowpack.

Total snowpack depths in this region are generally shallow, averaging around a meter at treeline.

• Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
• Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.
