Glaciers themselves form important landscape features of higher Himalayas. They have also influenced the geomorphology of the areas, which they occupied in the past, or occupy now. Their imprint on periglacial regions is also significant.
When glaciers in the form of continental glaciers (on lowlands or plateaus) or mountain or valley glaciers (in valleys or ice-caps on relatively isolated mountains or peaks cover land surface they produce distinct erosional and depositional features which characterise glacial topography.
In the glacial and periglacial regions, the heavy load of moving ice in addition to the various processes of ice erosion is responsible for plantation and development of glacial landforms including glacial pediments.
