Lost Cities of the Amazon: Ancient Civilization Discovered in Ecuador
A groundbreaking discovery in the depths of the Ecuadorian Amazon is reshaping our understanding of pre-Columbian civilizations in the Americas. Archaeologists, using advanced LIDAR technology, have uncovered a complex network of ancient cities that once housed at least 10,000 people about 2,000 years ago. These cities, which were home to the Upano people between 500 BC and 600 AD, reveal a level of urban sophistication that challenges previous assumptions about ancient societies in the Amazon rainforest.
The Role of LIDAR in Uncovering the Lost Cities
The discovery of these lost cities would not have been possible without the use of LIDAR (Light Detection and Ranging) technology. LIDAR uses laser pulses to scan the ground, allowing archaeologists to see beneath dense vegetation in rainforests and jungles where traditional archaeological methods struggle. This high-tech approach has revealed the intricate network of settlements, roads, and agricultural systems that once supported a thriving civilization.
The cities lie near the Andes Mountains, in the heart of the Ecuadorian Amazon. Despite being covered by dense jungle for centuries, the ancient cities are remarkably well-preserved, offering a glimpse into the advanced infrastructure of the Upano people.

A Highly Sophisticated Society
The size and organization of these ancient cities suggest that the Upano people had a highly structured society. Researchers have discovered extensive roadways, some of which stretch up to 20 kilometers (12 miles), and are up to 10 meters (33 feet) wide. These roads connected several settlements, forming a vast network that was likely used for trade, communication, and movement of goods and people. The scale of these roads is truly impressive, showing a level of engineering and organization far beyond what was previously thought possible in the Amazon region.
Moreover, the cities were not just about roads and settlements. Surrounding them were agricultural fields, irrigation channels, and intricate drainage systems, all suggesting a society capable of managing large-scale agricultural production and responding to the environmental challenges of the rainforest. These features point to a civilization that was not only surviving in the jungle but thriving within it.

Challenging Assumptions About Ancient Amazon Cultures
Before this discovery, many historians and archaeologists believed that the Amazon was sparsely populated prior to European contact. It was widely thought that the region’s dense rainforests were too challenging for large-scale civilizations to thrive. However, the discovery of these lost cities paints a different picture. The Upano civilization, with its advanced infrastructure and organized society, challenges these assumptions and shows that the Amazon was home to complex, densely populated societies long before Europeans arrived.
The sheer scale of the cities, along with their sophisticated urban planning and agriculture, highlights how much more we have to learn about the ancient cultures that inhabited the Americas. It also raises questions about the environmental impact of these societies and how they were able to manage such large populations in a challenging ecosystem.
A Window into the Past: The Lost Valley of Cities
Researchers are calling this discovery the “lost valley of cities.” The name is fitting, as the cities lie in a valley that was once a hub of civilization but has since been overtaken by the rainforest. With the help of LIDAR technology, these cities are now being brought back to life, allowing us to see the hidden legacy of the Upano people.
The discovery opens up new avenues for archaeological exploration in the Amazon. The cities and their road networks suggest a rich history of trade, communication, and cultural exchange within the region. This finding offers a unique window into a society that was adapted to its environment, showing us how ancient cultures in the Amazon managed to build large, sustainable urban centers.
The Significance of the Discovery
The discovery of these lost cities is more than just an archaeological breakthrough. It has profound implications for how we view the history of the Amazon and the societies that once thrived there. This new understanding forces us to rethink our perceptions of ancient civilizations, particularly those that existed in regions that were once considered inhospitable or difficult for large settlements.
The discovery also raises important questions about the environmental impact of these civilizations. Did they leave behind sustainable practices that could inform modern-day efforts to preserve the Amazon rainforest? What can we learn from their ability to manage resources in such a challenging environment?
Conclusion: Rediscovering the Lost Cities of the Amazon
The lost cities of the Amazon are a testament to the resilience and ingenuity of ancient societies. Through the use of LIDAR technology, we have been able to peel back the dense jungle to reveal a hidden network of roads, settlements, and agricultural systems that challenge our previous understanding of ancient Amazonian cultures. The discovery of these cities, and the sophisticated society that built them, is rewriting the history of the Amazon, proving that the region was home to advanced, densely populated civilizations long before European contact.
As archaeologists continue to explore this fascinating discovery, the lost valley of cities promises to reveal even more secrets about the Upano people and their remarkable achievements. This discovery is a powerful reminder that there is still much to uncover in the Amazon—and that the history of the Americas is far richer and more complex than we ever imagined.
