Whumpfs in Flanders
Date
Activity
Skiing
Skied the whitebark glade on Flanders and got several whumpfs at the mid and upper elevations. Light overnight and continued wind loading. There was a recent avalanche that appeared to be a wind slab with decent propogation on a north facing rocky slope. Visibility was too poor to get a good look or photo.

Continuous Collapsing at Bacon Rind
Date
Activity
Skiing
We got the same feedback that Dave and Doug did on 2/5/24 - collapsing every time we stepped out of the skin track or turned with any force, as well as a few sizable collapses triggered from inside the skin track. Very touchy, skied very well. Stayed well away from avy terrain.
