Snowpack Summary
At treeline and above 30 cm or more recent storm snow covers a rain runnelled crust. Storm snow amounts lessen and it becomes wetter or frozen at lower elevations, disappearing around 500 to 700 m.
Last week's rain storm saturated the snowpack at all elevations and pretty much removed all layering.
