There's a Tahoe Backcountry message board, although it seems not to get much traffic. Also a board on 395.com. And hey, I've been doing peak climbing in Northern CA for almost 35 years, now. Feel free to ask me about any peak! Yahoo, SummitPost, all deal with inane replies as does this board sometimes. I've got tons of maps, so can advise by that, too, on really obscure peaks and trails.
There's no more local Sierra Club support for intensive peak climbing, so don't bother with them. Most likely you'll get bad information or entreaties to not do any peak climbing. Some of them are good at extracting info from second hand sources, then giving them to you all mixed up.
I'd love to have a message board on my own site, but I don't have the memory or approval for anything but a manually controlled post situation. No money for software or web hosting at that level, either. Many posters have asked for a Northern CA climbing message board. I try to answer the best I can to e-mails from wherever, but I can't compete with people who are mountain locals, or with hundreds of posters contributing.
Hey, I was visiting the Mt. Shasta Ranger Station to snap photos and talk with the rangers just two days ago, so am updated on how things are run there. I hear the Lassen Loop is now plowed and open. Snapped many photos of the big mountain, but it was topped with clouds all of my trip.
