This is what I'm taking for my next 4 week winter trip to SW China and Tibet, starting on 12 Dec: Mont Nadgee sleeping bag, about 72 rolls of Ektachrome slide film for Rolleicord and Leicas, plus books, diary, sunies etc. Too much already - I may not bother with the thermarest and bivvy bag. Doesn't include the kit I'll be wearing - ie boots, hat, fleece, raincoat, etc. The plan is to start in kangding and retrace some of the previous routes ans see Minya Konka (Gongga Shan), Mutikonka (Maidi Gangga and Sanyanlong and the Yalong canyon near Jiulong), then on via Muli and Warizhen to to Yading (Konka Risumgompa) and finally down to Lijiang. Plan B is to just go to the Nujiang river again like last year.
