Avalanche Forecast

Moderate

No new avalanches were reported over the weekend.

A natural size 2.5 wind slab avalanche was reported from the Castle area on February 12th. It was believed to be 48-72hrs old and occurred in the immediate leeward side of a large, wind loaded north facing alpine feature.

Extensive wind effect in the alpine and at tree line. Wind slabs of various ages in lee areas (typically easterly aspects) and scouring in windward areas. A melt-freeze crust can be found below 2100 m. It may be on the surface on windward slopes and buried 30 to 60 cm deep in lee terrain. Good quality riding in powder snow was still being reported below 2000m on sheltered north aspects over the weekend.

The middle of the snowpack is consolidated. Weak faceted grains exist near the base of the snowpack.

The average snowpack depth is 130 cm. Up to 200 cm can be found in wind-loaded areas.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
