Dry snow found on steep north facing terrain above 10k. NE took heat in the morning and roller-balled below 10600'. East, West, South and lower angled slopes of all aspects are in a melt freeze cycle on the snow surface.

Avalanche Problem #1
Type
Loose Wet Snow
Problem #1 Comments

Steep solar slopes have seen natural activity with the warming. It was easy to get wet snow to build on itself and sluff skiing on a radiated east aspect at 10400'. The surface snow slid easily on an underlying crust.

Avalanche Problem #2
Type
Wind Slab
Problem #2 Comments

Most exposed areas above 10k have seen a great deal of wind effect. Most slabs aare likely unreactive but the possibility remains mostly on the east half of triggering something, particularly above 11k.
