A one-dimensional flowline model driven by equilibrium line altitude (ELA) lowering is used to investigate the effect of basin geometry on the dynamics of 2 palaeoglaciers, Puyehue and Rupanco, which occupied adjacent valleys in southern Chile. Model results are compared with the glacial geomorphology of the areas concerned. Specifically are investigated: the amplitude of the climatic deterioration necessary to reproduce the glacial maximum position of the 2 palaeoglaciers; the effect of valley geometry on the sensitivity and response of the palaeoglaciers; the varying response of the 2 palaeoglaciers as expressed in the depositional sequence
