In 1896, German explorer Eberhard Hermann entered a cave and found strange remains inside, the fur and bones of the extinct Mylodon sloth. Named after the giant ground sloth found within, Milodon Cave (Cueva del Milodon) is the largest of several caves within Cueva del Milodon National Monument. But the sloth wasn’t the only inhabitant of the caves. Remains of other extinct species, including a saber-toothed cat and a dwarf horse, as well as evidence of human habitation from as early as 6,000 BC have been found within the caves.
As visitors enter the monument, they’re greeted by a full-size replica of the mylodon sloth, standing 13 feet (4 meters) tall. The mylodon was said to resemble a giant bear, though the mammal was in fact a very large herbivore that went extinct over 10,000 years ago. A viewing point atop the cathedral-sized cave affords visitors views of the surrounding mountains, glaciers and the Eberhard fjord.
