Abstract
We present four glacial geomorphic maps of Llanquihue drift in the region of the southern Lake District, Seno Reloncaví, and the eastern half of northern Isla Grande de Chiloé, Chile. These maps form the basis of an interdisciplinary research project to establish a paleoclimate reconstruction of the last glacial cycle in the middle latitudes of the Southern Hemisphere. Therefore we stressed morphologic rather than lithologic units in our mapping program in order to delineate the glacial geomorphic forms that are surface manifestations of former ice‐marginal fluctuations. The resulting maps show the lobate shape and low surface slopes of the former piedmont glaciers that, at the last glacial maximum, spread westward from the Andes into the Valle Centralto fill Lago Puyehue, Lago Rupanco, Lago Llanquihue, Seno Reloncaví, Golfo de Ancud, and northern Gulfo Corcovado. These maps are the framework to tie together in this volume the stratigraphic sections and radiocarbon samples from within the Llanquihue moraine belts as well as the pollen cores from surface mires on the belts.
