In case you ever find yourself with too much snow this winter, learn how to build an igloo!

I slept the night in the igloo I built! The sleeping platform is a raised area. Because warmer air rises and cooler air settles, the entrance area acts as a cold trap whereas the sleeping area will hold whatever heat is generated by a stove, lamp or body heat. A cup of hot cocoa is warmly welcomed, though. 🙂
