So, I "re-did my room" yesterday. The snowy ceiling was starting to slump, making maneuvering difficult. So, I took everything out; sleeping pads, bags, totes with spare clothes, battery-powered alarm clock, PVC pipes for making breathing holes in the ceiling, and more. I used this opportunity to thaw all the ice off my sleep gear inside and dry it. Then I used a shovel to scrape another seven inches off the ceiling and put everything back.
On another note, tonight I will truly be tested. It's supposed to get down to -27. Lately, it's just been hovering around -19 to -23. I have a few tricks up my sleeve, like sticking a hot water bottle in my sleeping bag and lighting a candle inside the cave. Hopefully those will work.
