Glacial geomorphology between the Gran Campo Nevado and Estrecho de Magallanes, Chile (52–53°S, 73°W)

We present the first extensive high-resolution glacial geomorphic map west of Andean Cordillera in southernmost Chile (52.8–53.1°S, 73.0–73.9°W). The extends over 1565 km2 and is based on satellite images aerial photographs. At selected locations, remotely mapped geomorphology was corroborated by field observations. study area dominated erosional landforms (77%) depositional (23%), with published submarine having been included (e.g. moraines). Glacial drift, kettle kame topography lateral frontal moraines form primary sediment associations. cirques, wide U-shaped valleys, whalebacks, roches moutonnées scoured bedrock characterize most area. spatial distribution whalebacks indicates a lack lithological control their formation warm-based, dynamic ice velocity thickness regime during Patagonian Ice Sheet cover retreat last cycle.
