Glacial streamlining

The landscape of East Lothian, like much of Central Scotland, shows a pronounced grain, a result of streamlining of the terrain under ice sheets. The flow of ice was roughly from west to east, with deflection around hill masses. The ice flow determined the orientation not only of the landforms of glacial erosion, such as crag and tails, but also of meltwater channels and the fluted ridges of glacial deposits. Streamlining thus reflects a complex blend of glacial landforms.
