The Skardu Valley, at the confluence of the Indus and Shigar Rivers, is wide by long. Active erosion in the nearby Karakoram Mountains has resulted in enormous deposits of sediment throughout the Skardu valley. Glaciers from the Indus and Shigar valleys broadened the Skardu valley between 3.2 million years ago up to the Holocene approximately 11,700 years ago.
