The avalanche on Wolverine slide aprx 1500’. Both were in wind loaded areas at upper elevations. Ski cuts with snowmobiles were not producing avalanches in protected areas.

Wind slabs on Saddle

Date
Activity
Skiing

It looked like there were several small wind slabs triggered on Saddle Peak. I was skiing with my family and didnt get a good look or a photo. One appeared to be just off the summit maybe 12" deep and not running very far at all. The other appeared to be near the going home chute even with the cliffs, and this one ran a bit further. These wind slabs looked like something to be looking for but also easy to avoid.
