It is one of the great pleasures of a visit to Mount Rainier NationalPark to wander over the fields of snow and climb out on the Nis-qually Glacier and explore its crevasses and ice caves. Like all glaciers, the Nisqually gathers on its surface masses ofrock with which it strews its sides just as rivers of water strew theirbanks with logs and floating debris. These are called lateralmoraines, or side moraines. Sometimes glaciers build lateralmoraines miles long and many feet high, as you will see when youvisit the Mount Rainier National Park. The rocks which are carried in midstream to the end of the glacierand dropped when the ice melts form a terminal moraine.
