Glacial moraines. Aerial photograph of the folds of a moraine on the Malaspina Glacier,Alaska,USA. Moraine is rubble material that has been transported and deposited by a glacial surge (downwards movement of glacial ice). Most glaciers are currently receding,but several,notably those in Alaska,show regular surges that produce moraine patterns | |
