Comments
Snow depths in the Grizzly Gulch / Twin Lakes Pass area ranged from 50cm to 75cm. The right-side up new snow was mostly stable consisting of 4F+ DF near the ground, lightening up to F hard new snow near the surface. A slight density change about 15cm down from the surface was the weak layer in a small SS-N-R1-D1-S that likely occurred overnight Sunday 11/8 on a very steep north facing chute along Fantasy ridge.

North facing Fantasy Ridge SS-N-R1-D1-S. 10,400', 10' wide, 15cm deep.
Comments
Coverage is still very thin but what a difference one storm can make.
Comments
Very little wind effect up high in this good base building storm. Overall LOW hazard. This pit location was at 10,200', East-facing, along the Twin Lakes ridge. 77cm total depth. 40cm 4F+ closer to the ground with 37cm F near the surface.
