Glacial geomorphology of the former Patagonian Ice Sheet (44–46 °S)

We map the glacial geomorphology of former Patagonian Ice Sheet between 44°S and 46°S. Building on previous work, our covers a ∼50,000 km2 region west-central Patagonia. The study area includes eastward-flowing Río Pico, Caceres, Cisnes, Lago Plata-Fontana, El Toqui, Coyt/Río Ñirehuao, Simpson/Paso Coyhaique, Balmaceda palaeo-outlet glaciers, adjacent valleys, Andean Cordillera. inventory contains >70,000 individual landforms mapped from remotely-sensed imagery field surveys. Mapping was classified into ice-marginal (e.g. moraine ridges, trimlines), subglacial lineations, flutes), glaciolacustrine palaeolake shorelines, perched deltas), glaciofluvial proglacial outwash plains, meltwater channels), non-glacial palaeochannels, landslides or slumps) landform groups. new will inform future interpretations regional glacier dynamics, development robust geochronological datasets that test timing glaciation deglaciation.
