I just stumbled upon this - curious to know where the Wuse icefall is.
(btw original reference was a 1500m ice route on the NW Face of Mt. Siguniang noted here)
Most water ice climbs in the Siguniang area are found in Changping and Shuangqiao Valleys, although there are many more in the vicinity they are just a bit more difficult to get to. Wuse is about 10km up Shuangqiao Valley.
The Siguniang page includes many peaks in the area in addition to the four summits of Sinugiang itself.
I plan to put up info on ice climbing in the area on the Ice Climbing Forum later this year.
