Wildly different snow in different aspects

Very different snow conditions on different aspects Northwest facing at 6300 feet was about 10 cms or less on a very solid wind crust (maybe 5 cms). Very stable but not a lot of joy to ski East facing at 5600 feet was very light large faceted snow. See pictures but flakes were easily 1cm or bigger. Skiing was fabulous in the open trees. Most of that face is in the shade all day.
