I was up there in an aircraft last couple of days in support of this search.
Morning time seemed to be fairly solid. Afternoons, you'd see little rivers of snow cascading off the mountain.
Here is an image from the NW side of the mountain -- notice all that brown? it wasn't there when I was up there on Thursday.
