Abstract
The paper presents a glacial geomorphological map of landforms produced by different glaciers in East liddar during the past. The map has been created as the necessary precursor for an improved understanding of the glacial history of the region, and to strengthen a program of dating glacial limits in the region. The map was produced using Landsat TM, ASTER DEM, Google Earth™ imagery and field validation. The different landforms which were mapped include: lateral moraines, terminal moraines, proglacial lakes, palaeo-cirques, erratic boulders, outwash plains, whale backs, glacial grooves, rochee mountanee, drumlins, glacial striations, hanging valleys debris/talus cones, subglacial material. Glacial-Geomorphological features are very significant for palaeo-climatic reconstruction, showing variations, temporally and spatially. At the same time these landforms, which are also altered by processes prevailing during interglacial period, helps in geo-environment studies.
Highlights
Glacial geomorphology is the study of landforms produced due to glacial and fluvioglacial processes in the areas of present glaciers as well as in the areas covered by glaciers in the past
Geomorphological features which acts as indicators of retreat or recession of glaciers includes: Glacial grooves, cirques, moraines, hanging valleys, glacial lakes, whalebacks, rochee mountanee, erratics, outwash plains, debris cones
Based on satellite data and field expeditions carried out in east Liddar valley well developed Glacio-geomorphic features were identified like terminal moraines, lateral moraines, cirques, glacial lakes, whalebacks, rochee mountanee, erratics, hanging valleys, debris cones
Summary
Glacial geomorphology is the study of landforms produced due to glacial and fluvioglacial processes in the areas of present glaciers as well as in the areas covered by glaciers in the past. Much of the remarkable characters of the present topography in the northern part of east Liddar valley have resulted from the glacial processes in the remote past. A study of the glacial processes operating presently can throw light on the landforms that were produced by the similar processes in the past. It will be helpful in reconstructing the origin of landform features [1]. The aim of the present study is to produce a reliable glacial-geomorphology map of study area and will be used as the foundation for dating glacial limits in the area (Table 1)
