Also called the Durung Drung Glacier, it is located in Himalayas, India. It reaches an altitude of 21,490 feet. Fortunately, you can reach the Drang-Drung Glacier by car or bus. This glacier is the source of the Doda River and Stod River. “Come rain or shine, or even snow, some glaciers of the Himalayas will continue shrinking for many years to come,” according to Homeland Security News Wire. Some are worried within the next few decades the Himalayan glaciers may disappear, eventually causing the rivers to run dry.
