Be very aware of this stuff, very hard ice crust on top of snow that is like sugar. When the crust breaks it is like being in loose sand and trying to climb a lip that keeps breaking, often with ice at the bottom for extra fun. You can end up doing a lot of digging. Where I took these pictures it was not an issue, but a couple of spots could have been.
