Hand pit show 1-2 inches fresh over a 1-2 inch stubborn wind slab. Then 2-3 inches soft unconsdolidated snow on top of a very stout 3-inch rain crust. Discussed this on the way up, agreed that if the wind slab broke, then the 2-3 inches below would likely cause miminal harm. Slope was not very steep, also agreed that steeper runs should probably be avoided for the day.
