No idea. Snowing all day, sideways from every direction. Shoveled the same spots 6 times, but there is no snow on either side of where the wind wants to lay it down:) Mountain was the same, couple gusts tried to knock you down, one tried to take the pack away while de skinning, drifts were soft and the skiing was quality Fun storm, windows continue to shake and the temps are down now to 23F .
