The Paleolake Tehuelche is the name for several former lakes that existed in the area of Torres del Paine in southern Patagonia.
[1] These were proglacial lakes that existed next to the Patagonian Ice Sheet during the Late Pleistocene and Early Holocene.
[1] About 38,000 years BP an early Paleolake Tehuelche existed and drained eastward through Turbio River.
[1] A particular lake named Great Tehuelche Paleolake covered what is now Sarmiento and Del Toro lakes plus a large area to east making Cazador Range a peninsula[2] until about 7,113 years BP when the lake drained and ceased to exist.
