Where the handle 'mutikonka' comes from

When trying to think of a unique name to use online I thought of the mountain 'Muti Konka' that few if any westerners have seen since Joseph Rock described it in the 1920s. Here I am having re-discovered the peak, which is located above the Yalong river canyon in Sichuan. The nearest town is Jiulong, about three days by 4WD and on horseback/trekking. It's inaccessible!
