Evidence for late-glacial ice dammed lakes in the central Strait of Magellan and Bahia Inutil, southernmost South America
This paper critically appraises the evidence for a succession of ice-dammed lakes in the central Strait of Magellan (c. 53°S) c. 17 000-12 250 cal. yr BP. The topographic configuration of islands and channels in the southern Strait of Magellan means that the presence of lakes provides compelling con...

This paper critically appraises the evidence for a succession of ice-dammed lakes in the central Strait of Magellan (c. 53°S) c. 17 000-12 250 cal. yr BP. The topographic configuration of islands and channels in the southern Strait of Magellan means that the presence of lakes provides compelling constraints on the position of former ice margins. Lake shorelines and glacio-lacustrine sediments have been dated by their association with a key tephra layer from Volcan Reclús (c. 15 510-14 350 cal. years bp) and by 14C-dated peats.
