The Drang-Drung Glacier is a long river of ice and snow, a source of the Stod River, a tributary of the Zanskar River, itself a tributary of the Indus River.
In this mountainous region, the Drang-Drung Glacier plays a crucial role as the source of the Stod River, which flows into the Zanskar River and eventually contributes to the Indus River's vast network.
