This is the most remote trek and very high-altitude glacial basin which ranges over 16 km at the head of Biafo and Hisper Glaciers. These all glaciers meet at Hisper La. The very beautiful Ice rivers connects Hunza and Baltoro. Here many rare animals like snow bears, Markhors and snow leopards are found. Martin Conway describes the snow Lake as “Beyond all comparison the finest view of the mountain it has ever been my lot to behold. And Eric Shipton describes it as “The Last Blank on the map".
