More than twenty five years has passed since we were captivated by a remarkable high mountain range, 40km far away to the north, seen from the top of Tso Karpo Kang (6556m) in the northeastern corner of Kanjiroba Himal in 1971. Name of these mountains was quite unknown at that time., We had only a vougue idea they must be on the Nepal=Tibet border and in the easternmost part of Mugu district. On old maps by Survey of India, from 1930's, afterward, the name Kubi Kangri was roughly given to these mountain ranges, probably from the data of Sven Hedin's expedition in 1907. How to access to these mountains, has long been the center of our interest thereafter.
