10:15 -Standard approach Trail consisted of dense, wet, progressively crustier surface snow. Conducted one test pit near treeline plateau, moved up towards Common Bowl Ridgeline where we dug our 2nd test pit.
Encountered no slide activity, heavy wind scouted ridgelines observed on all major ridgelines and across towards Seattle Ridge.
Weather was consistent with predicted forecast.
-10:30-broken sky, no precip, calm sporadic winds , no higher than 5 mph.
-11:45-1pm. Light winds, light precip above 2,500 ft, pockets of blue, primarily overcast but good depth visibility in snow surface.
-2:30pm-visibility deteriorates and winds picked at 2,800 ft. heading SW.
Below 2,000 ft. Dense, wet snow with gradual crust building as we ascended higher.
At 2,000 ft, HS 50cm with top 5cm of settled, dry powder snow(slightly wind packed.
At 2,400 ft and above, dry surface powder with obvious wind slab deposits and scoured ridges.
HS 68-72cm at 2,270 ft.
No precip ,
