Description :
Glacial geomorphology around the Northern Patagonian Icefield indicates that a number of fast-flowing outlet glaciers drained the icefield during the Last Glacial Maximum. Here, a detailed regional map of glacial landforms around the Northern Patagonian Icefield, data from satellite images and digital elevation model (DEM), ice thickness calculations, are presented and discussed. The influence of the fast-flowing outlet glaciers on icefield behavior may explain why the configuration of the Northern Patagonian Icefield at the Last Glacial Maximum is not accurately represented in existing numerical ice-sheet models.
