Comments
Many whompfs on the way to peak of Powder King. 30cm new snow in the past 3 days has been affected by moderate to strong SW winds forming sensitive slab conditions on northerly treeline and alpine terrain features. The new snow and slabs sit atop 25cm of sugar garbage facets. This problem is unlikely to go away any time soon.
