Snow Characteristics Comments
Checked new snow/old snow interface at 10,000" and 9,500". At 10,000" shovel tilt test showed new snow/old snow interface not bonding well due to a graupel sandwich 10 cm to 15 cm from the surface. 11 cm of dense saturated new snow took on slab characteristics. Skied down N facing Patsy trees and noticed roller balls coming off my turns (wet loose) and cracking on steeper slope (wet slab).
