Significant surface hoar.  Some feathers near~5mm. Quite variable snow surface over the length of the slope. Slight crusting at the higher elevation, significant crust mid slope, unconsolidated powder near the base.  Snowballs rolled on the surface, continued quite a distance, moving on the surface hoar.

Mostly consistent snowpack to approx 48cm. Approximately 5 cm ice layer, which appeared to be frozen rain.  Grading density from surface to that depth, F to 4F/1F.  Below the ice, 1F to near the ground.  ~5cm ice layer there was firmly bonded to the ground surface.
