When it's this cold, everything freezes. I had a hard time getting my tent up to temperature when I first arrived. I let the temps get down to -10 overnight inside the tent, and everything was frozen when I woke up. Veggies, oil, cords, water ... even my honey bucket. But I was so warm in my big puffy sleeping bag. I had 2 steak sandwiches and I visited my other tent and fixed it. The snow crushed the tent, but I didn't know that the tent came with a centre pole if needed.
this was a really good night in the tent. Lots of Northern lights and cool tricks to show how cold it really was out there.
