RE: How do you keep a tent warm at 11,000 ft ?
The camp I referred to was at 10,500 (up on the CO flattops).
Now I've also heard of people using Charcoal briquettes to heat their tent. I'm thinking of trying that next fall.
I used to buy hard wood in Denver then take it up, but have since stopped for the most part (may take enough wood for the first few hours, for some reason its either raining or snowing when setting camp up).
I've also used one of those Alaskan stove's from cabelas. Those are great if you want to warm up real quick, but just can't hold the heat.
My stove is probably on the small size for my tent during a winter hunt. I'd probably opt for the next larger size if I hunt 3rd or 4th season a lot.
