evidence: The Southern Patagonian Ice Field: A Glacial Wonderland of Chilean and Argentine Patagonia Stretching across Chile and Argentina, the Southern Patagonian Ice Field stands as an immense testament to the glacial history of this region. Holding the distinction of being the world's second-largest contiguous extrapolar ice field, it constitutes the more significant remnant of the Patagonian Ice Sheet. [...] The Southern Patagonian Ice Field is a remarkable geological entity situated in the southern reaches of the Patagonia region. It is the more significant remnant of the Patagonian Ice Sheet, which covered south Chile during the last glacial period, locally known as the Llanquihue glaciation. Comprising both northern and southern lobes, the modern ice fields, though diminished from their peak around 18,000 years ago, still rank as the southern hemisphere's largest expanse of ice outside Antarctica.
