Through the Great River Trenches of Asia: Joseph Rock, National Geographic Aug 1926, originally uploaded by jiulong.
Kham then and now. How Southwest China looked in the 1920s and when revisited from 1991-2025 by Michael Woodhead of Sydney, Australia. Based on the explorations of botanist Joseph Rock.

And the same peak, I think, in 2007:

The NW of Yunnan area encompassing the Three Rivers - the Dulong, the Salween (Nu Jiang) and the Lancang (Mekong) rivers. Click here for a more detailed version. Key: black cross = Protestant church, white cross = Catholic church.
This is the crude road along the Nu river (Nujiang, or the Salween as Rock called it), from Bingzhongluo to Chawalong (Tsarung). I will write more of my trip when I get back to Australia. I also have plenty of other material to publish including new photos and info from Yongning.
I'm on the Nujiang river, following in Rock's footsteps throught the communities of Lisu and Nu people in NW Yunnan. I have my 8 year old son with me so won't be doing anything much adventurous.
This is the grave of Pere Genestier, the French missionary priest who gave Rock shelter during his Mekong-Salween trip that he described in "Through the Great River Trenches of Asia".
Some great pictures of Lijiasun (a village between Lugu Lake and Muli) by photographer Chen Qingang can be seen at:

After spending a cramped night sleeping on the floor of the filthy houses in Mundon (猛董) we hitched up our horses and set off up the hill to see the mountain Maidi Gangga (麦地贡嘎, Muti Konka). This involved a long haul up the hillside through burnt out forest. It culminated in this spectacular view of the valleys below, before we turned around a spur and into the Chang Haizi valley.

This lake near Jiulong is now a tourist resort - funny how Joseph Rock never mentioned it despite passing by twice on his way between Muli and Kangding. Most people photograph it from the oppposite direction - this is looking south back towards the lake and the tourist cabins on the other side.

This is looking back towards Kangwu Shan - the pass between Jiulong and the dead-end valley (Yangwe Kong) leading to Sanyanlong.

In 1923, two years befor Joseph Rock arrived there, two other Americans viited and photographed the Tibetan monastery at Choni (Zhuoni) in Gansu province. They were By Janet and Frederick Wulsin, wealthy Americans who were based in Beijing. Frederick was an aspiring naturalist and took a Graflex camera on this expedition. These are some of the many photogrpahs he and his wife took - and which are now in the archives of the Peabody Museum at Harvard University. They are taken from the book Vanished Kingdoms by Mabel Cabot (daughter of Janet).
