I broke trail up Flagstaff Shoulder this morning at about 8 AM. I found widespread sensitivity in the new snow on leeward terrain features, and I remotely triggered numerous very soft slabs to the east of the shoulder, out on the face, as I climbed through the trees and over all the little wind drifts that grow along the upper shoulder. These slabs were between 6 to 12 inches deep, but they would mostly"eat themselves up" immediately after releasing. Where the slabs were deeper, as in the attached photo, the weak layer was just above the melt freeze crust from Monday 1.14. Elsewhere, there are sensitive density inversions within this morning's ~12". Generally I think this avalanche problem is manageable in most terrain. However, as of 10 AM, it's still snowing pretty hard in upper LCC, winds are still transporting snow, and if temps continue to warm, I think this avalanche problem will become less manageable. Note: leaving Alta last night at 7:30 PM, rain or freezing rain was falling at ~8700', on top of the very light density snow that had fallen earlier in the day. It would be interesting to see if there's a thin rain crust out there an inch up from Monday's snow surface.
