The Penitentes of Tapado Glacier, Dry Andes of Chile. On low-latitude glaciers and snowfields, penitentes are spear-like shapes made of snow or ice, ranging in size from centimeters to meters. Their name came from the similitude of a field of religious orders doing penance during Spanish Holy Week (Penitentes).
