In this false colour image, the Susitna Glacier in Alaska seems like a river fed by its influent streams and flowing towards the valley. Due to the depiction in false colour, the vegetation in this picture is bright red, the pure surface of the ice is light blue and white, ice covered with sediment (medial and lateral moraines) is brown and water is dark blue. The dynamics of the glacier are most striking in the middle of the picture where you can see a tributary glacier pushing its ice masses sideways into the trunk glacier.
