The Glacial Map of southern South America

This paper describes The Glacial Map of southern South America. This is a new map of the glacial geomorphology of southern South America between latitudes 38 degrees S and 56 degrees S, approximately the area covered by the former Patagonian Ice Sheets. The map was compiled from interpretation of remotely sensed images (Landsat 7 ETM+, pan-sharpened Landsat 7 and ASTER scenes). The mapped geomorphological features include terminal moraines, glacial lineations, ribbed moraine, glacier debris stripes, trimlines, empty cirques, plateau edge, volcanoes, meltwater channels, deltas, glacial lake shorelines, alluvial fans, sandar, and glacial lake outburst flood tracks. The map also indicates the current extent of major icefields and glaciers in the area, as well as other topographic features such as lakes, rivers, shorelines, deltas, plateau surfaces and volcanoes. We briefly describe the most commonly occuring glacial landforms and provide an overview of their distribution within the mapped area.
