Avalanche Summary
On Tuesday, multiple skier-triggered wind slabs on loaded and cross-loaded features up to 90 cm deep were reported at treeline. Widespread wet loose debris was also reported at treeline and below from a natural avalanche cycle that occurred during the rain event. These avalanches are from the southwest of the region.
In the north of the region, one natural size 1 wind slab was reported on a northeast aspect in the alpine on Tuesday.
Snowpack Summary
Check out this great MIN describing conditions at Shames.
5 to 15 cm of recent snow has been redistributed by southerly winds. Below about 1500 m, this snow sits on a crust. Several other crusts exist in the upper snowpack.
Two buried surface hoar layers may still be found in the mid-pack in isolated areas.
Snow depths are highly variable throughout the region, ranging from 100 to 300 cm at treeline and tapering rapidly below.
