Clear skies through mid morning progressed to broken skies and patches of low lying clouds with a cloud level of about 5000-6000ft by midday. Intense sun was hot! By 1300hrs a few snowflakes began falling.
Old D1 slab avalanches were visible on steep rolls, beneath cliff bands and small cornice features. We suspect the avalanches ran mid-storm, midday yesterday, likely when winds were gusting strong for a few hours. They were partially filled in. We suspect crowns were ~6” to 1ft.
Extensive slope testing by others out enjoying the low density snow didn’t yield any avalanches to our knowledge. A couple very small wet loose slides were noted around 5500ft on SE aspects midday.
Patchy old snow was present at 2000ft, and 3/10-11 storm snow began at about 3000ft, and was a dry, low-density 6” by 3500ft.
From about 5000ft and up the snow was variable due to wind-effect, although it was still dry and low density, and mainly averaged just under a foot deep before you encountered the underlying 4/10 crust.
Beneath 5000ft, the crust was only a couple inches thick, and punchy when you got off the sled. At higher elevations the crust was thicker but snow was dry beneath the ~10cm crust where I dug at about 6000ft. We found the new snow layer was well bonded to the crust.
Upon our return to Schriebers Meadow at 3500ft at 1pm, the snow was moist, even though it was on a flat surface.
