Bee I agree. I have flown under a hood and been in a whiteout. The reason they call it a whiteout is because you can't see anything but white.I have been in Mammouth in a whiteout on a well marked trail and had to take off my skis and walkout because I couldn't see. It was hairy scary.I couldn't imagine going down the backside of Whitney and down the switchbacks cables or slope (whichever is being used now) in true whiteout conditins.
