This detailed topographic and hydrological map illustrates the Late Pleistocene (Last Glacial Maximum, LGM) river system and paleochannels of Northern India, including parts of Pakistan, Nepal, and Bangladesh. The map highlights modern river courses in thin black lines and Pleistocene rivers in solid blue, alongside paleochannels and former courses shown with dotted blue lines. It also indicates glacier extents with white areas, and a dashed line marks the coastline during the LGM, approximately 120 meters lower in sea level than today. Key rivers such as the Indus, Ganga, Yamuna, Sarasvati-Hakra system, and Brahmaputra are labeled, set against geographical features like the Himalayas, Thar Desert, Indo-Gangetic Plain, Arabian Sea, and Bay of Bengal, providing insight into significant geological and climatic changes in the region’s riverine landscape during the Ice Age.
