probably not a polar bear skin, looks more like sheepskin to me.


I've overnighted in an igloo. It's surprisingly warm. Let's face it, snow is a magnificent insulator. It's crucial to build it so there's a cold sink. You need to sleep on a shelf with a lower space below the sleeping area where the coldest air will collect. It's also important to leave a hole in the top to let the warm air escape, or you'll get condensation and maybe drips. Of course, you need an insulating pad because the snow's cold, but that's easy.

the one in the pictures is HUGE, the one I slept in was much smaller. Making them is also warm work I can tell you.
