The image shows four smaller tributary glaciers flowing into the main Siachen Glacier. The many dark, parallel lines in the glacier and its tributaries are moraines, which give a sense of the southward flow of the glacier. The darkest and most prominent moraine results from the merging of moraines from the Teram Shehr Glacier and its neighbor immediately to the north. Early afternoon sunlight casts shadows from small cumulus clouds onto the glaciers’ surfaces.
