Snow Characteristics Comments
Nice springlike "corn snow" in lower elevations on supportable snow in the afternoon, especially nice on lower angle slopes. The crust was variable, softening, and sometimes breakable at mid elevations on east facing slopes. Nice recrystallized snow on north facing slopes, but upper level faceted layers dominated by a deteriorating 2.5 cm thick rime-crust buried under 4 to 6 inches of very loose faceted snow...

In east and southeast facing terrain, the surface snow was moist and the crust under it was supportable until mid-afternoon when it softened and became breakable in places. I could see icy pillars and clusters of large rounded grains in the moist weak snow (rounding faceted snow) under the crust.
In north facing terrain, thick layers of very loose faceted snow exist both above and below a deteriorating 2 or 3 cm thick, brittle rime-crust.
