It's less cold than it looks, i've tried that.
Snow is an excellent thermal insulator, and the air in that chamber can be quite warm, like 15°C, without really melting the snow.
I oh also love not wearing clothes as soon as the room temperature hits 15C. Now it all make sense.
Warm sun + 0 wind chill + being acclimatised to 5C or less. Same deal as people suffering from heat stroke in 29C when parts of the world regularly don't fall below that for months out of the year.
Mur it's good to get out of the breeze. And wouldn't it be better if it was lower to the south, to enhance solar gain? :-D
Feel free to crosspost it! I'm always wary of posting in more places myself because I feel like I'm too omnipresent in the communities I already post in, lol.
