Possible information: when snow is compressed, it tends to turn into ice, and that lasts longer. (I know this because in some weathers, footprints on snow make an ice footprint impression, and then the snow can melt and you're left with these baffling ice footprints on nothing as the last thing to go.) So if your snow lasts more than one day, or you have freeze/warm/freeze cycles after a compression, perhaps that's relevant? I don't know how MUCH compression you need to get the ice result -- any human walking on them will do it, but I'm unsure about just falling snow.
