unfortunately no board to take good measurements with, but I did find somewhere between 5-6" for the first wave and 7+ inches just now with snow nearly stopped here in Gaithersburg (NE side, near Laytonsville). So, around a foot, probably with some compaction especially with wave 1. Sure was easy to shovel the 2nd wave, SO light and fluffy! Now will wait for my cul-de-sac to be plowed out...
