Observations
Ski cut the slot on belay and cut multiple surface soft slab pockets at the entrance. The soft slabs were not very cohesive and failed to entrain much snow beneath them but ran the length of the couloir. The upper most turns were shallow on top of crust and the first pocket ran on a firm crust layer that was near the surface. Lower pockets ran on a storm interface.
Phantom trees is still quite bony with lots of branches and snags lurking under light snow. Slot apron also had several surprising sharks poking out and just beneath the surface at the bottom. Exited via snow lake and did not get good observations of the thunder exit.
