Like mentioned previously, once the winds began howling in earnest, we stayed low for the rest of the day. However, even below 9,400' there were shallow 2-4" wind slabs that would crack out around your skis. As a result, we stayed in lower angle terrain. However, you could get the shallow slabs moving on any steeper rolls such as road cuts, etc.

I would guess there was a natural cycle at the upper elevations; however, its possible that the winds were so strong that the snow was just stripped and blown west to Park City without too much loading. Will find out in the morning.

Tough to say what the hazard was, considerable in most places, but could have reached high at upper elevations, tough to say given the inability to see anything.
