Resumo: The Alps experienced extensive glaciations during many Pleistocene cold stages. New stratigraphic and geochronological data gathered in the last decade depict the Early Pleistocene glaciations and their record is continuously updated. The onset of major glaciations since the late Matuyama Chron (MIS 22-20) is better recognized in many end moraine systems along the southern side of the Alps. The updated chronology of the Middle Pleistocene phases indicates an improvement of the knowledge about the penultimate glaciation (MIS 6) and the evidence that every sector has had its own most extensive glaciation in a different time span. The dissimilar architecture of the end moraine systems suggests a different behavior of the glaciers from one cold stage to the others. The development of the largest glacier networks with associated piedmont lobes (i.e., Adige, Adda and likely Inn) required abundant snow supply promoted by the southerly circulation, like in the LGM. For the systems with the highest accumulation areas (i.e., Valais, Dora Baltea, Rhine-Reuss and Ticino-Toce) a larger number of glacial units was recorded likely because these were more sensitive to every circulation regime impacting the Alps, whether northwest or south dominated. The Alps remain the most studied mountain range with respect to Quaternary glaciations, thereby providing a unique and valuable resource.
