Glacial moraines. Aerial view of zigzag folding of a moraine on a glacier. A moraine is rubbly material that has been transported and deposited by a glacial surge (a down-glacier movement of ice). Most glaciers are currently receding,but several,notably those in Alaska,USA,show regular surges which leave behind moraine patterns such as those seen here.
