Observations

Took the Iron Goat Trail up from Scenic and followed the south ridge. There was some consolidating snow down low, but it was punchy when I arrived in the morning. Once I got more under treeline, however, a lot of the snow disappeared (I assume rain shadows and sun were the causes). At 2.8k’, the snow increased, but still appeared to be less than 2’ deep. Low coverage snow continued up to 3.6k’ or so.
Much of the observed issues were wet loose related and because the latest storm layer hadn’t bonded to the crust directly below it.
I didn’t find any evidence of wind slabs up to the summit, but I didn’t actively seek them out (route is almost entirely S facing). Saw some evidence of past E hanging cornices near the summit.
Descending was difficult because the top layer wanted to slide under my snowshoes and because heel plunging was going up to my thigh (at least 2’ deep) between 4.5k’ and 4k’.
