Glacio-Geomorphological Investigation and Deglaciation pattern of Nehnar valley, North Western Himalayas

Glacial landforms are pieces of evidence to comprehend the glaciological past and paleoclimatic conditions in the region. In paleo-glacial reconstructions, a critical geomorphological context is provided for determining glacial chronologies. The study provides a detailed geomorphological mapping and investigation of the Nehnar valley, NW Himalayas, Jammu and Kashmir, India. To map the glacio- geomorphological features, the study uses LISS-IV (5.8 m resolution) and Google Earth Pro (1 m resolution) images as well as morphological sketches and GPS data collected during field visits. The Advanced Spaceborne Thermal Emission and Reflection Radiometer Digital Elevation Model (ASTER-DEM, 30m resolution) has also been used to enhance the morphological and elevation characterization of glacial features. A host of glacial features like lateral and terminal moraines, serrate, debris cones, moulins and outwash plains are among several others mapped in the study region. Using dating techniques, the spatial data on glacial landform features in the area can be used to guide the reconstruction of paleo-glaciological setups. This fills in some of the gaps in our knowledge about glaciation in the Kashmir Himalaya during the Pleistocene.
