Thanks a lot, that is a trick I will remember.


Not that I am in the habbit of charging into steep terrain in zero visibility conditions... but whiteout is very common in snow covered, three-less mountains. All it takes is low lying clouds and the light will be dispersed so evenly between the snow and the clouds that everything snow covered will be obscured and there is no shadow, no 3D information. Spooky.


Luckily, the very tiny bit of whiteout / close-to-zero visibility navigation I've tried have been along routes I've known like the back of my hand AND where I have confidence there are no lethal terrain surprises .... Still spooky.
