Just cause you can't even sprinkle water on snow doesn't mean nobody can. How'd you like to put your money where your mouth is? i"'ll be you a year's pay I can do this. no problem. we used to do it as kids. I go up to illinois to see an old friend every year. 0F is nothing much. I used to have to feed cattle and move them to the pond or the well in -20F as a kid, with just 2 sets of clothing, pos cotton gloves, coveralls and a hat.
You don't know what you don't know.
Hopefully you never need to survive in your powder snow igloo. I suppose since you can get by overnight in cammies and a watch cap, down to 0 degrees F, you will be fine....lol
