Snowmobiling

We rode to the cabins in Fisher Creek and skied up Wades World. A slide from last week was visible and we dug a few hundred feet above it. A 70 cm wind slab broke on the facets in our stability test and also in the avalanche. We got 2 large collapses as we approached the crown of the slide and another an hour later near Henderson Mtn. On Henderson Bench we could see 2 new avalanches that looked fresh, possibly cornice triggered. It was not windy, so windloading was not the trigger. Regardless, it was disconcerting. Across the Fisher Creek valley we could see a slide on the nose of Sheep Mountain on the same slope that killed a snowmobiler in 2015.

Whumpfs yesterday and today, recent slides, and a poor snow structure is worrisome.
