Here’s How LiDAR Technology Revealed an Ancient City Older Than Machu Picchu

This ancient city may have been a template for the city of Machu Picchu, an ancient Inca city founded in the 15th century.

A sensational discovery has been made using LiDAR technology once again as scientists revealed they found the remnants of a long-lost city that predates the Inca capital of Machu Picchu.

Albert Lin,  an explorer from National Geographic , along with archaeologists Adan Choqque Arce and Thomas Hardy, managed to draw a complete map of the city – colonized most likely by a pre-Inca culture – thanks to LiDAR, a remote sensing technology which uses the pulse from a laser to collect measurements which can then be used to create 3D models and maps of objects and environments.

According to reports, the ancient city revealed by LiDAR is located at an archaeological site known as Wat’a, located at an elevation of 4,000 meters, which means its more than 1,500 meters above the elevation of its more famous counterpart Machu Picchu.

Wat’a which means “island” in the native language consists of five sections: Wataqasa, Willcapata, Qhawarina, Qullqa, and Saksaywaman Pata.

Despite the fact that the ancient city had been studied and excavated by archaeologists before revealing tombs, ceremonial plazas, residential areas, and a large defensive wall, the new LiDAR scans have helped experts see elements that had previously eluded experts, heling them identify never-before-seen features like typical Inca-style terraces, among other things.

Speaking to Newsweek, Lin explained that “It is very challenging to get there.”

“You’re at around 13,000 feet of elevation and its mostly open landscape because there’s not a lot of trees around, so you’re basically baking in the high altitude sun, all the way up.”

Unlike Machu Picchu which has been excavated and restored, many ancient Inca and Pre-Inca settlements, located high up the Andes mountains, remain hidden due to more than a thousand years worth of vegetation growth.

Therefore, seeing terraces, plazas, and even buildings is nearly an impossible task, and many elements of known ancient sites remain hidden “beneath the surface”.

That’s precisely where LiDAR comes into play, helping experts see what they cannot with the naked eye.

LiDAR has already revolutionized archeological proving to be a must-have tool for experts trying to uncover lost cities and ancient cultures.

The ancient city is interesting because—like at other sites found across Peru—the Inca appear to have constructed on top of more ancient pre-Inca settlements.

But what is perhaps most interesting is that the researchers who participated in the latest expedition argue that the recently revealed city may have been, in a way, a template for the city of Machu Picchu, an ancient Inca city founded in the 15th century.

“See it as an evolution on their pathway towards Machu Picchu,” Lin said to Newsweek. “I think it’s quite an inspiring place to be.”

LiDAR technology is widely used by experts across the globe. Not long ago, LiDAR scans have helped archaeologists find more than 60,000 lost ancient Maya structures that remained hidden deep beneath extensive layers of Jungle.

The data provided by LiDAR has helped scholars estimate that as many as 11 million people may have inhabited the Maya lowlands during the Late Classic Period spanning between 650 and 800 CE.
