3. The Pleistocene Ice Age

During the Pleistocene Period the effect of ice age was noticed in the Himalayas, especially in the Karakoram and the Greater Himalayan ranges. The erratic rocks, boulders, cirques, eskers, rock polishing, buff-coloured sands, and luminated clays inter-stratified among the karewas deposits of Kashmir, Bhadarwa (Doda), and Ladakh give enough proof of the Pleistocene glaciation. The Pleistocene glaciation also led to the formation of a number of high altitude glacial lakes of the Himalayas. The Kailash-Kund, The Sanasar Lake near Batote, the Gul marg-basin, the Sheshnag, and the Gangabal Lake are some of the examples of this type of lakes. The Peninsular part of India has no evidence of Pleistocene glaciation.
