Rock and debris falling from mountains lands on the glacier surface. Sand, gravel, and large boulders polish and gouge the surface of the bedrock that they are dragged over leaving glacial striations (Fig 5-4). A glacier is a large, perennial accumulation of crystalline ice, snow, rock, sediment, and often liquid water that originates on land and moves down slope under the influence of its own weight and gravity. Glaciofluvial deposits or Glacio-fluvial sediments consist of boulders, gravel, sand, silt and clay from ice sheets or glaciers.They are transported, sorted and deposited by streams of water.
