If when you mention Tahoe, that would have to be outside Desolation. In Wildernesses, you can supposedly only gather down wood, so it would be tough in Desolation where fires are banned but not sure about their take on woodstoves and gathering fuel for it. Yosemite will be tough too, may have to be selective and look for Lodgepole meadows for their limb wood. Otherwise, in NF lands, you are free to use any deadwood for stoves, you'll probably be limited to limb wood as it is easy to break off. With more snow, you can reach trees now that had previously been stripped by summer campers who did not have the snow to stand on.:) I just sold my old snowmobile last weekend, but I liked taking it snow camping as I could ride around in an area, get a lap full of firewood and drive back to my campsite. Enjoy your trip when you get out, I've been solo on two snow trips already this winter, headed out again this coming weekend. I have so many old bp stoves, I have to get out and we have over three more months to do more snowcamping.
