Size 3: Could bury and destroy a car, damage a truck, destroy a wood frame house, or break a few trees
In addition to MANY wet loose D1 & D2 on all aspects that likelu ran by or on 3/23/22, also noticed this large D2-3 Slab avy that may have been part of the deep persistent W-N-E problem. Did not witness it run.
Signs of Unstable Snow
Circumnavigation of Table Mountain beginning w Artists Point. Added on lap of Mazama Bowl prior to exiting via Bagley Lakes Basin. While lots of rain runnels and avy debris crossings, snow seemed very stable tho didnt dig any pits. Did choose a couple descent and ascent routes cautiously to play it safe (especially Mazama Bowl, where I began to punch through when I tried to bootpack final couple hundred feet of late-in-the-day re-firmed reascent - had to use cornice fall debris to attain ridge) and avoid creek/lake openings. TONS of wet loose on all aspects. Lots of largw cornice development on many aspects (esp looming toward Table Mtn Northern Ridge Extension from Herman Pass…beware in top). Snow firmed up quickly once direct sunlight ended.
Observed Avalanche Problem #1:
All aspects D1-D2 likely during 3/23 warming/rain event if not beforehand)
Observed Avalanche Problem #2:
D1 SW Aspect near Ptarmigan Ridge from minor wind loaded feature (may have fractured as mini cornice)
Observed Avalanche Problem #3:
Deep Persistent Slab
NW aspect. Again unsure if it was the called out problem as too far away to evaluate (off of Ptarmigan Ridge). Definitely slab avy tho
