Plan on hiking Yosemite Valley – LYV – Merced Lake on Dec 31- Jan 5. Will there be snow? Will I need snowshoes? Micospikes?Dec 5, 2012 at 3:33 pm #1933385
There will be some snow, but hard to tell from now how much there will be. Maybe a little, maybe a lot. So maybe snowshoes, maybe not. Microspikes or other traction devices would definitely be a good idea, though, as the trail up to and down from LYV is likely to be icy.
If you check Badger Pass for snow depth, you can expect somewhat more than that at Merced Lake.Dec 5, 2012 at 6:02 pm #1933431
Watch for avalanche danger. I saw firsthand the devastation that they can cause. I have done many snowshoe trip deep in the winter Sierra and while it is extremely cool, be careful. Doing a trip this early could mean unconsolidated snow which will be a chore even with snowshoes. Nobody can answer your questions…… You could see a winter storm dump multiple feet of snow in late December or nothing. If you are in to Sierra hiking check out going in over Kearsarge Pass if rom the east. You can do the Rae Lakes loop or a loop over Junction Pass. My Avatar picture was taken from 13k on Junction Pass in early May. I think April and May are the absolute best times to snowshoe the Sierra. Enjoy.
Ps, some of the trails going to LYV will likely be closed due to ice. Check the park page.Dec 5, 2012 at 6:27 pm #1933436

The series of switchbacks at Bunnel Point (sp?)–just after the two bridges that cross the Merced River about five miles up from LY valley campsites–can be dangerous, depending on conditions. For two reasons. First: it's not at all obvious, but there's avalanche danger from above. Study your map here. Second: there's a serious icing problem here. For a very brief section, that's nevertheless dangerous, it can become difficult to get grip without crampons or microspikes. It all depends on how snow and weather unfold. If you're bringing an ice axe, you're fine.
There's also avalanche hazard at the bridges.
There can also be a tricky stretch just before the final bridge re-crossing the Merced a mile and a half or so beyond the switchbacks I just described. It's steep and if icy, and you slip, you go into the Merced just before a series or waterwheels. And there's no way around it. You won't survive. It's a short stretch and soooo enticing because you just know that you're going to make it….
Both of these sections go through freeze/melt cycles that are conducive to ice. The switchbacks are worse: meltwater flows onto them from above during the day, and that freezes at night.
Otherwise this can be a delightful trip, just beautiful, you won't regret it if the weather cooperates! And think about day-tripping up towards Vogelsang pass. Honestly, if you can, plan an extra day for this. It's the best part of the venture; well worth it. You may be surprised at how this south facing, sun exposed section is snow-freeish.
Wait, late Dec.-early Jan. is typically one of the stormiest period in the Sierras.
Seriously check the forecast. Are you familiar with the Sierras in winter? I personally would never set in stone a winter trip in that time frame if I was coming from out of the area.
EDIT: geeze, I forgot: the stretch from Happy Isles to the top of Nevada Falls can be icy, especially along the mist trail! Very steep here, and awful if icy.Dec 6, 2012 at 5:46 pm #1933704
There are many great trips out of Hetch Hetchy if you are just getting started on winter camping in the Sierra. The grand-daddy of them all is the 45 mile loop up to Tilden Lake returning through Jack Main Canyon. Falls Creek needs to be crossed but it will have snow bridges after a certain point. There's a bunch of shorter loops or out and back trips as well. That is where I learned how to snowshoe.Dec 7, 2012 at 10:58 pm #1933979
Hi Greg, do you have a trip report for that?
I'm very interested in doing that loop sometime soon and want to get as many details as possible.
I'm assuming there's not much snow until you climb a few thousand feet above the resevoir?Dec 8, 2012 at 12:14 am #1933984

I've seen two inches of fresh snow at Rancheria Falls, which is not far above the reservoir… and that was in summer. I would suggest that the trail around Hetch Hetchy can have snow during any winter storm and it may last for days afterward. In fact, the rangers may block the access road at Camp Mather due to slippery surfaces.
