Ridges or deposits of rock debris transported by a glacier.

Moraines are left after a glacier has receded, providing evidence of its former extent. Common forms are ground moraine, formed under a glacier; lateral moraine, along the sides; medial moraine, down the center; and end moraine, deposited at the terminus.
