Rode up 10 miles towards the head of the drainage and poked around on mellow slopes. Significant winds started from the SW and shifted to the west, transporting snow 200+yds below ridges. Observed the avalanche above, as well as the smaller ones that slide on NE aspects around 6,500 ft previously. Talked to some riders at the end of the day who saw 4 separate crowns in other bowls near the ridges. Also saw some recent cornice fall on S slopes above the major slide paths on our way out.
On our skin up, no shooting cracks were observed and none of the new, dense snow slid around on side hills. It took multiple jumps on switch backs to get them to shift. New snow wasn't consolidated enough to slab where we skinned and skied.
3 new inches around 5,000 ft, 8 new inches at 5,800 ft, and 18 new inches at 6,000 ft. Temps reached 40° at 6,000 ft and steep, sun affected areas began to rollerball around 11:30. On E slopes around 6,500 ft new snow was saturated 3 inches deep at 3 pm and 8 inches deep on SE slopes at 3pm.
Pit results showed around 250 cm of snow, with ECTN 9 30 cm down on snow interface between warmer new snow and the colder, drier new snow. ECTN 11 15 cm down, and ECTN 15 45 cm down on a below a small melt freeze crust 1 inch on facets above the consolidated, dense, old snow surface.
