Good point on the debate thing - i'm in. Forgive the spell check issue though. OK - instead of asking myself WHAT I would put on a 5 lb baseweight list, I thought about what would I NEED in those conditions, and how much does it weigh? I started with Ryans ingoing scenario (about the 3rd post on this thread.) He needs to be covered for above treeline, storm conditions, 3 days/2 nights.
Then I thought, OK, what do I NEED in terms of snow melting. shelter, etc. When I got to the shelter part I figured:
below treeline, storms - Alphamid
bleow treeline, light snowfall but safe - Spinnshelter (for full protection)
However, I'm guessing that since the criteria is above treeline/stormy, a snow cave scenario is the only way to even consider a sub 5 lb weight. The minimum shelter I'd carry above treeline in winter is likely a Bd firstlight, carbon poles. Weight is around 2# 6 oz I think, which wipes out the 5 lb idea. So I'm going to re-think the gear list based on a snow cave scenario They take a long time to build, but ryan didn't say he needed high mileage, so maybe a 2 night, three day trip can utilize a snow cave that would be used for 2 consecutive nights. Hike in/build on day 1, hike a loop on day 2, hike to car day three. I haven't done the weight math, but some thoughts I'll be considering under this scenrio:
2L aluminum pot, lifter, flame, screen, lid, etc - 8.2 oz
large fuel canister - I think around 4.5 oz.
This would get him water and warm drinks.
arc x bag - 15.2 oz
P3D overbag - 11 oz
down hood - 3 oz
Gets him down to Zero, and the high % of synthetic might get him through snow cave issues.
maybe Montane superfly jacket
w/b gloves for building the cave. Hopefully he can build a cave in reeds/momentum/ w-b gloves
As you can see, the weight is soaring and I haven't done the math. But this might be the lightest scenario for above treeline, I'd just need to tweak a wet snowbuilding clothing list and see where the numbers come in.
