Something that has been hidden for thousands of years has been uncovered. V-shaped stone walls have been revealed by satellite images: 76 daunting structures lined up on the slopes<\/strong>. They look like random ruins, but they are anything but. Researchers are delving into their investigation to gain insight into earlier civilizations in the pursuit of understanding the past and how humankind has developed over the centuries.<\/p>\n

Where have these 76 structures been found?<\/h2>\n

This find has experts rather excited. Dr. Adri\u00e1n Oyaneder from the University of Exeter explains that these are Chacu ruins. Ancient animal traps, built with real skill by prehistoric hunters. They used the landscape of the Andes<\/strong> to their advantage.<\/p>\n

These marvelous Chacu ruins have been found in northern Chile’s Camarones River Basin. Some of these ruins run for 150 meters or more, made with dry stones, nothing fancy, just careful hands stacking rock after rock.<\/p>\n

Why do these stone ruins in the Andes look like this?<\/h2>\n

The arms of the V narrow as they drop downhill. These ruins in the Andes were designed like this to channel animals<\/strong> into round pens sunk two meters deep. The people who built them knew exactly what they were doing because the V-shaped ruins were used to drive herds of vicu\u00f1as into their grasp.<\/p>\n

Vicu\u00f1as are those wild, deer-eyed cousins of alpacas. The spots for these animal traps were chosen quite smartly. These 76 Chacu ruins aren’t scattered at random. They hug steep slopes, blend into gullies, and line up perfectly with the lay of the land.<\/p>\n

These animal traps weren’t the only ruins found in the Andes<\/h2>\n

Something else was found along with the ruins of these ancient animal traps. Oyaneder also found nearly 800 smaller structures<\/strong> nearby. There were little circles of stones, clusters of huts, outposts tucked into the terrain, and they all sit within a few kilometers of the big stone walls.<\/p>\n

It’s a whole landscape built for tethered mobility. People moving with the vicu\u00f1as, camping, hunting, and living in rhythm with the animals. High in the mountains of the Andes, people adapted to their surroundings and forged a life we would do well to learn more about.<\/a><\/p>\n

What makes these ancient ruins in the Andes particularly interesting<\/h3>\n

The intriguing aspect of this find is that it seems to be older than the Inca ruins, possibly thousands of years older. Before, archaeologists figured that once farming and herding took off, large-scale hunting faded out.<\/p>\n

But this find in the Andes goes against that story. Oyaneder’s evidence points to these traps and camps being used<\/a> from at least 6000 BC right up into the 1700s. So, even as farming spread, hunter-gatherer life didn’t just vanish. It remained in the Andes.<\/p>\n

Many ancient civilizations used the same kind of stone funnels to trap animals<\/h3>\n

Old Spanish records even mention foraging groups called “Uru” or “Uro” living up there<\/strong>. The stones match the stories. This same approach has been seen in ruins found elsewhere. In places like Jordan and Uzbekistan, people built desert kites.<\/p>\n

It’s the same kind of idea. Stone funnels to trap wild animals. Built by different people in different places, but with the same idea at the core. It’s fascinating to see similar ideas not bound by location and shared by civilizations that lived very far from one another.<\/p>\n

What the discovery of these ancient stone ruins in the Andes means<\/h3>\n

Ancient ruins help us uncover how ancient civilizations lived. Chile’s V-shaped stone ruins do just that. The people who built them established a system with camps for their people and traps to catch animals.
\nChile’s ruins also point to seasonal movement.<\/p>\n

The ruins in the Andes also allude to knowledge being passed down from one generation to the next. Dr. Oyaneder and his team are gearing up to go back, date the stone traps, and dig deeper. They’ve already done some 3D photography, but there’s still so much to learn.<\/p>\n

They’ll try to determine who exactly lived there, how these networks grew, and just how far they reached. Who knows what else they might find? These ruins are a revelation and one that needs more investigation. A story of an ancient people<\/strong> may have chapters to it, still hidden underground<\/a>, waiting to be found.<\/p>\n","protected":false},"excerpt":{"rendered":"
