Moderate to strong SW to W winds loading the Negatives and forming numerous Wind Slabs in the Alpine. At treeline only shallow isolated Wind Slabs noted. Alpine varied from 2" to 12", more in favored areas. Noted three debris fields - 2 rather large D1's and a possible D2, difficult to ascertain since the debris was partially covered.
