Comments
Small LW triggered a SS-N-D3; my partners thought it looked like a hard slab, I thought it was size 3.5 so we are meeting near the middle. Appeared to have happened just before our arrival in the morning on 3/1 or possibly sometime on 2/28. Crown was 3'-5' deep and still very sharp. Couldn't see the toe of the debris but assume it ran down to around 8800' based on the shape of the terrain. This seemed like a notable event.
LOTS of very poor stucture on the N side of the compass down south. The slab sitting on top of our mid-winter drought layer is much thicker and more well connected than in the Central Wasatch. And yesterday was likely the warmest day of the season so far. We backed off our main objective and skied 30° powder in the trees.
