Toured through the trees to top of alder line. Lots of whumphing and propagation throughout the day.
Obvious signs of instability
Observer Comments
Broke trail through the trees to the bench above the alder line. Had significant whumphs/collapsing and shooting cracks all day long. We kept terrain very mellow and avoided the steep gullies between ribs. We had whumphs propagate above us, on the up, anywhere from localized to over 50/60 yards above us. On the decent, had propagation above and to the side of ski tracks. Noticed natural slides in several of the gullies, the slopes above the trees, marmot, 4068... light was flat so it was difficult to see all of them. Due to the low angle we chose today, we did not have anything slide on us. Most of the collapsing seemed to fail on that thick layer of large grained facets near the ground.
Weather
High overcast, flat light, 20 degrees, very light wind above alder line that diminished throughout the day.
Snow surface
Settled powder from recent snow this week. Ski pen ranged from ankle deep to knee deep when breaking trail (I'm 5"4'). Ski poles still penetrated to ground most of the day.
Snowpack
No formal pits were dug.
