Sterling Mountain AST 1

Good visibility, yet no avalanches observed. 10-15 cm new snow overlies last weeks breakable temperature/rain crust. Surface hoar observed in snow profile on N aspect at treeline down approximately 20 cm giving moderate, sudden planar (pops) results in two compression tests. The mid-December rain crust was noted down approximately 50 cm. Snow immediately above and below crust is faceted and weak (4 finger resistance). Facets on both sides of the crust produced inconsistent hard, sudden collapse (drops) results in multiple compression tests.
