Near PL 25cm of loose and wind transported broken particles on firm base. Few 1mm surface hoar particles on snow suface. Transitioned to mostly wind-transported snow near ridgetops
Loose snow to 3800 ft. Above there evidence of wind transport removing loose snow and exposing old M/F crust. Did pit at 4300 ft on NE aspect. Got STN and CTN. See attached.
