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.

Looking forward, we expect both natural and human-triggered avalanches to remain unlikely.

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 5 cm of recent snow in sheltered areas.

A second layer of surface hoar found around 50 cm deep has produced limited results with snowpack tests and is not a concern at this time. The rest of the snowpack is mostly made up of weak, faceted crystals, along with a crust near the base of the snowpack.

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

• Watch for areas of hard wind slab on alpine features.
• Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.
