GEO-GRAPHIC: Moraines. (A) This diagram illustrates how different types of moraines form. (B) An outlet stream from the Piedras Blancas glacier in Patagonia, in southern Argentina, has cut a V-shaped notch into the terminal moraine at the base of the glacier. The terminal moraine has formed a natural dam behind which a tarn has formed. A lateral moraine and a recessional moraine are also visible in this photo.(© Michael Schwab)
