doesn't need to be ash, could be just dust + gravel a couple of feet off the highway (with intermittent snowfall)Quote:

If thick enough to separate the snow layers, it will clearly be a weak layer.
If a layer of ash sits on top and gets sun, I would think it would make an ice crust much faster than white snow would, so once buried it could be a slick bed surface.
I wonder how it affects the sintering process once buried?
Interesting snowpack for sure.
wouldn't an ash layer act like any other dusk layer and be super reactive in warm temperatures, posing a great threat by creating wet slabs?
