I don't know if anyone watched, but History Channel (I think) had a 1 hr. documentary w/ the "Arctic warrior" course in Alaska last night. 13 days, in temps down to -50.

Brr!

Some interesting things:
- People burn about 4000Cal/day (as opposed to a normal 2000-2500Cal)
- Using a modified A-frame snow shelter is quite comfy. They used a parachute as the "support" for 10" of snow, using the hole at the top as their "door". Very cool to watch them make it.
- Anyone know pros/cons of snowshoes vs using XC skis?
- They use a 3-layer system too - polypro base, heavy fleece layer, gortex shell. Occasionally some wore white overpants (layer #4).
- The USGI sleep system is rated to allow 4 hrs of sleep at -40 temps.

If anyone gets the chance to catch it on TV, taping/DVR'ing it might be a worthwhile thing. Very interesting program.
