More detailed information about the snowpack: 

At 7000ft HS of 70cm and HSt of 10cm, and at 8000ft HS of 260cm and HSt of 20cm. Under recent storm snow, a light crust was observed at all elevations on E/NE aspects travelled today.

Video: At 8000ft just below Flagpole summit and adjacent to natural loose dry that occured yesterday. 45 degree aspect, 36 degree slope. Light wind transport visible in video, but no wind slab encountered today. At same location, RB5.5 EB below crust.

In addition to column tests: mitt pits, hand shears and ski cuts all showed continued potential for loose dry above the crust, with not enough slab development nor weak layer development for slab activity. Grains below crust are only partly faceted, with some angles visible to the naked eye.
