For Jack and anyone else excited about this as their first Winter/Snow trip: I just wanted to ease some of the burden , but none of the excitement, of this trip. Hopefully you won't have to rush out and spend $$$.
CAVEAT: I've only snow camped on the Western Sierras and further South, which, at its worst, I feel it's amateur.
So, with the best intentions, I hope this comes off OK…
IMHO:
As you know, it's about being warm and dry, learning and having a good time. This is a great beginners trip. Being only 4-5mi from the TH, there's an easy exit if mistakes are made and accidents happen. Keep in mind that it's Yosemite, the Western Sierras, (not Eastern) and less than 7600'. Which means we'll have typically predictable weather, good storm warnings, which most will heed, sunny warm days and nighttime temps above 15F. Typically. ::grin:: NOAA will have good reports for all this.
While some Four-Season and Expedition Winter gear is great, if you don't have them, don't worry, neither do I.
Feet:
Water proof, and roomy for extra socks if cold feet is an issue. Insulated is nice but really not key. VB is neat, but also not needed. Just be water proof. Insulated booties are nice at camp, but I didn't get a pair till last year.
Hands:
Shell Mitts are great. Bring 2-3 liner/inserts to swap and layer. Avoid mitts or gloves with built in lining/insulation, IMO. They get wet and then tacky and you can't get your hands/fingers inside… I'm never totally happy with my solutions for hands, but I'm convinced by shell mitts.
Bottoms:
Soft Shell is my favorite. It'll repel moisture and are highly windresistant, and may have insulation (I choose layering over insulation at all times). Wear a pair of med weight bottoms during the day. Bring another or heavier pair for night time. Insulated pants are great at night, but it really depends on your needs. I'm warm, myself. If you can't/don't have soft shell, just make sure it's a synthetic bottom and have a shell handy.
Tops:
I wear one or two base layer merino wool tops while moving. I keep a wind shell ready, and bring a rain shell in case. I also bring a, lets say, medium-warmth down jacket: Montbell AlpineLite. Once again, this is up to individual needs, but I feel like the trip doesn't require much.
Head:
The hood from your wind jacket and a warm hat is fine. I bring a balaclava, and my base layer merino is hooded, not an insulated hood.
Sun Protection:
Sun block and sunglasses are key. Lipbalm too.
Cooking/Water:
Canister or White Fuel will be good. Just be careful of your stove sinking in the snow that melts under it. Ti plate helps, I made a Reflectex base and lined one side with over-liner. Alky just won't cut it for melting snow and may have issues at 15F anyway. Buddy up with someone for melting/cooking. Or just say yer "no-cook" and mooch. I usually do with Josh. SUL, BABY!!!!
Shelter:
I've gone just a TiGoat bivy, non-water proof, dug a grave for wind and been fine. I've gone Epic Bivy and Tarp and had to ditch in a storm to Josh's Nallo. I like a pyramid style floorless singlewall. You can use a 3-Season free standing. You can experiment and team-up with someone with a 2-3person in case you have trouble and need a backup plan. You'll be digging, so bring a good collapsible shovel, not those stupid plastic claw shovels.
Sleep:
Up to you, but I can get away with a 20F bag, a 1/8" Thinlight, Nightlight, and add another 1/2" blue foam if needed.
Sitting Around:
Someone with a tarp would be helpful in case there's weather. But I've only needed/wished for it a few times. Bring a foam sit pad, maybe from your pack frame, maybe from your sleep system, maybe just for sitting. And remember the shovel for digging a kitchen.
Snowshoes:
covered by others… Try renting MSR's. The shoes for rent at Badger (they have them) suck.
Misc:
Splurge on the weight of a double wall mug. Heck, a thermos! I never bring one, I always miss it.
Cable ties – I've repaired a broken snowshoe with em.
Warmers – I shouldn't caution against safety, but remember where we're going. I've never brought the stuff, I've been in the worst conditions Dewey has, e.g. freezing rain (first time out, all gloves wet, bare hands), and 4' of snow overnight. I was always OK. Just never mind I said these would be useless weight.
Tent Anchors – Again, ignore me, but don't bother with snow anchors. Bring 5-6" pieces of wood, the thickness of garden stakes. Really.
Bear Canister – hmm.. Never seen a bear or it's tracks up there. The ravens are more a threat, I feel. Don't know what to say about this. I don't think I bring one (why can't I remember)….Anyone? Bueller?
Here's "what may be construed as criminal activity" warning:
I like to build a fire if I can.
I don't think I bring a bear canister.
I dig a cat-hole (not to the ground, not 6" into frozen ground), not a wagbag, but use a snowcone to wipe.
I bring booze for warmth and conversation.
I bring a boombox, and shoot flares, and throw M80's, who cares. (i made a rhyme)
cheers all. looking forward to the snow.
