Today we went into Skimuah drainage to see if we could find any more deep slab avalanches and assess how the new/old snow interface is holding up. We traveled on south facing slopes up to 6000' in elevation.
We traveled in wind sheltered locations, so we never saw evidence of wind slabs. I anticipate by the sound of the wind up high they were present at upper elevations. The forecast matched what we were finding at mid-elevation, south-facing slopes, which made us comfortable skiing avalanche terrain with slope angles up to 40 degrees. We gave the runout of Mt. Penrose a wide berth after seeing that it had not run yet.
Two avalanches had crowns at mid elevations that were likely triggered from above. Other debris pile likely started at upper elevation.
Best guess at the timing. Overnight or on 1/28.
