Observation Details

While ascending, SE winds were gusting strong although there was minimal snow for transport since the winds from the past week scoured most of the snow in the slide. A lot of the mellow-angled terrain was thin but most rock and ice hazards were well enough covered and made for smooth and fun riding. At the junction where the slide splits, we opted to go up the looker's left slope because the main slide (looker's right) was mostly exposed ice bulges. We did not detect any instability in the snow while ascending - although noticed a lot of surface and depth variability caused by the wind scour. We dug a pit at the bottom of the left slope at about 3200' and the snow depth was measured to be 65cm.
