Abstract

Mapping is based on visual interpretation of landsat 7 ETM+ and Terra ASTER satellite images, including the contemporary glaciers, areas of ice-scoured bedrock, trimlines, glacial lineations, terminal moraines, sandur and fluvial sediments, deltas and ice-contact deposits and alluvial fans. Recesssion of the icefield is marked by 3 distinct moraine sets, interpreted as marking terminal positions related to the little Ice Age and 2 preceding phases of Holocene glacier expansion. The AA. argue that glacier response to first-order climate forcing is tempered by second-order controls introduced by regional-scale topography effects
