Tyndall's Trail of Bergs: Ice splintered off southern Patagonia glacier drifts across a growing glacial lake‎

The Southern Patagonian Icefield is the largest expanse of ice in the Southern Hemisphere outside Antarctica. The mass of glacial ice extends hundreds of kilometers along the spine of the Andes, feeding dozens of dynamic outlet glaciers that grind their way down from higher elevations. Many of these rivers of ice terminate in the sea or in proglacial lakes.
