Glacier-based reconstructions of Equilibrium Line Altitudes (ELAs) are important to understand changes of temperature and precipitation over longer time scales and may help to validate regional palaeoclimate models.

Abstract
Glacier-based reconstructions of Equilibrium Line Altitudes (ELAs) are important to understand changes of temperature and precipitation over longer time scales and may help to validate regional palaeoclimate models. Here, we present new insights into the ELA in the south-eastern part of the European Alps during the Last Glacial Maximum (LGM, 26.5 to 19 ka), based on the geomorphological record of the Monte Cavallo Group (Venetian Prealps, NE-Italy). This mountain range hosted a glacial system that remained isolated from larger valley glaciers in its vicinity and therefore likely responded very dynamically to changes in climatic boundary conditions. Through detailed mapping of glacial sediments and landforms, we were able to constrain the extent of these palaeoglaciers and model their surface geometry and ELA via semi-automated toolboxes in a geographic information system. In the absence of numerical datings, these landforms were related to an LGM advance through geomorphological and st...File | Dimensione | Formato | |
