Post-LGM glacial and geomorphic evolution of the Dora Baltea valley (western Italian Alps)

Paleoglacial reconstructions in the European Alps have mainly focused on specific climatic periods such as Last Glacial Maximum (LGM) or Younger Dryas, with few studies investigating post-LGM Alpine glacier fluctuations encompassing broader temporal periods. In this study, we present a detailed reconstruction of glacial history Dora Baltea catchment, which hosted one main Quaternary systems western Alps. By combining existing and new chronological constraints from postglacial landforms/deposits into 2D 3D ice surface reconstructions, quantitatively reproduce timing ice-configuration six LGM to early Holocene paleoglacial stages. Our deglaciation sequence along valley can be correlated Lateglacial paleoclimatic periods, line other areas. We estimated paleo equilibrium-line altitudes (ELAs) for each stage, using empirical ice-geometric methods. results indicate low ELA sensitivity decay during stages deglaciation, despite significant retreat piedmont massifs, suggesting major role catchment topography controlling estimates large systems. Finally, provide two valley-slope collapse events, both postdating withdrawal but implying different landscape response time well triggering factors.
