Good Day for Mellow Turns

As expected... It's spooky out there! We did a few yo-yo laps in the mellow glades at treeline on Hilda. Widespread evidence of a large natural cycle from the last storm; all aspects, all elevations. Lots of whumphing on the way up including a monster whumph that I triggered when I stepped off my skis into unsupportive snow to transition at an exposed treeline knoll... cracking and whumph propagated 50-100m in all directions lasting more than a second and circling back around. Skiing was great in the mellow glades with 10-15cm powder turns. We did find a couple pockets of unreactive windslab isolated to exposed ridgecrest and there was obvious wind effect/sastrugi in seen in the alpine/treeline and around Parker ridge. We avoided all avalanche terrain and overhead hazard and had a great day. Snow profile details in the snowpack section.
