Pro-glacial stream in Greenland |
We also need to consider how features
like rivers and lakes also affect the "glacial" landscape. Rivers fed by
glaciers have very distinctive characteristics, such as high sediment load
and very variable discharge, that cause very distinctive fluvial landscapes.
Many glacial landscapes also include lakes ponded up by the ice. When the ice eventually disappears, these lakes can leave distinctive shorelines on the hillsides and distinctive flat-lying sediment-fills in the valley bottoms. |
