A high-desert time capsule
In the arid Patagonian steppe of Argentina's Neuquén Province, Cueva Epullán Grande shows the past. For thousands of years, this cave provided shelter for hunter-gatherer groups. The site's dry, cold environment created perfect conditions for preserving organic materials that would normally decay, including textiles woven around 500 AD. The cave was a temporary camp; it was also a burial site, with archaeological excavations revealing human remains alongside everyday objects. The long history of human activity is also etched into the rock itself, with petroglyphs on the cave floor dating back as far as 10,000 years.
The textiles discovered here are made from the fine undercoat of the guanaco (Lama guanicoe), a wild camelid native to South America and ancestor of the domestic llama. This soft, warm fiber, with a diameter of about 16-18 microns, was a prized material for ancient Andean cultures. The weaving techniques used to create these 1,500-year-old fabrics are complex, showing mastery of the craft. Remarkably, some of these same techniques are still practiced by indigenous Mapuche weavers in the region today, demonstrating a long continuity of cultural knowledge.
