  • Glacial fluctuations during the Late Pleistocene in the Central Pyrenees was studied using 36Cl cosmogenic dating of moraine and rock glacier boulders, and polished bedrocks. This allowed us to establish a sequence of stadial and interstadial events in the headwater of the Gállego River basin and in the Marboré Cirque. Results demonstrate: (i) the rapid glacial retreat after the LGM; (ii) the great sensitivity of small glaciers to climatic variability; (iii) the occurrence of re-advances within a general deglaciation process, during Greenland Stadial-1 (the Oldest and Younger Dryas); (iv) glacial retreat was very rapid during the Bolling/Allerod (Greenland Interstadial). Late Holocene recorded glacial fluctuations in the uppermost parts of the Pyrenees: re-advance at Mid Holocene, a general retreat during the Bronze/Iron Ages, a short expansion during the Dark Ages, a melting period during the Mediaeval climatic Anomaly and a glacial expansion during the Little Ice Age.
