Abstract: Foreshortening/layover 5 1500 Log scaleDiverse velocity in WKS• We examined 36 glaciers in WKS. 25 glaciers flow continuously (Duofeng, N3-6, S1-8, etc). 3 glaciers are extremely rapid (N2, West Kunlun, N7). 8 glaciers are stagnant (Zhongfeng, Chongce, etc).Divide Log scale [m/yr] 5 500 Flow line and error estimation Divide Log scale [m/yr] 5 500 ① We set flow line center of glacier (North 17, South 19).② Average surface velocity with 10×10pixels (i.e.500m×500m) along flow line and estimated standard deviation as error.③ We excluded if sample number ≤ 50 pixels or standard deviation >30m/year.Only surge type, we excluded if sample number ≤ 25 pixels.Reservoir area Receiving area Reservoir area Receiving area Ice thinning (and retreat) Ice thicken and steepen Ice thicken Ice thinning Dynamic Balance Line Crevassing and advance Quiescent phase (10~100 years) Surge cycleActive phase (= Surge) ( several months ~ 10 years) Active phase of glacier surgeCase : N2 and West Kunlun glacier
