International audience Here, we reconstruct the glacial history and chronology of a previously unstudied region of Patagonia that formerly hosted the Río Corcovado (43°S, 71°W) outlet glacier. We present a new set of cosmogenic 10Be and 26Al exposure ages from moraine boulders, ice-moulded bedrock s...
