Wind slabs are likely to be largest and most reactive in steep alpine features.
Recent snow and moderate southerly wind have formed wind slabs at treeline and above. The most reactive slabs will be found in the alpine.
On Tuesday, there were reports of skier triggered wind slabs up to size 1 in steep NE terrain. Sluffing was reported to run fast and far on sheltered north aspects.
Some sluffing was reported on Monday.
On Saturday, a skier triggered a wind slab on a northeast-facing alpine slope near Sky Pilot.
15 to 40 cm of snow overlies the early February crust with the deepest deposits on northerly aspects at treeline and above. This snow is reported to be well bonded to the crust.
The remainder of the snowpack is well-bonded.
The snowpack depth at treeline ranges from 90 to 170 cm. The snowpack depth tapers rapidly below treeline, especially on south aspects.
