Went up to the summit of observation then skied down the SE chute and out on the lower slopes. Windslabs building in the alpine with steady moderate winds gusting into strong. The gut of the chute we skied slid naturally in the last 12hrs. Saw surface hoar growth at TL on the approach that should get blown away. Of note we saw 4 size 1 slides on glacier ice on the observation North glacier (2nd photo).
