Cirques are basins created by erosion and weathering at the upper end of a glaciated mountain valley. Horns are rugged, pyramid-shaped mountain peaks created by erosion on several sides of a mountain. Cols are saddle-shaped gaps between horns. Tarns are lakes formed on the bottom of cirques after the ice has melted. Lateral moraines are deposits of debris such as gravel and sand along the side of a valley glacier.
Terminal moraines are similar deposits at the end of a glacier.
