Karola Glacier is backed by the south slope of Naiqin Kangsang Peak (7191 meters), one of the four peaks in Tibet. The location of the film "Red River Valley", "Battle of the River" and "Yunshuiyao". Unfortunately, in order to create a real avalanche situation, the Red Valley filmed a triangular gap on the Kajola glacier with explosives, which can be clearly seen during the tour. As one of the famous ancient glaciers, the gap will never be filled again.
