Douglas Preston writes: The ruins were first identified in May 2012, during an aerial survey of a remote valley in La Mosquitia, a vast region of swamps, rivers, and mountains containing some of the last scientifically unexplored places on earth.
For a hundred years, explorers and prospectors told tales of the white ramparts of a lost city glimpsed above the jungle foliage. Indigenous stories speak of a “white house” or a “place of cacao” where Indians took refuge from Spanish conquistadores — a mystical, Eden-like paradise from which no one ever returned.
Since the 1920s, several expeditions had searched for the White City, or Ciudad Blanca. The eccentric explorer Theodore Morde mounted the most famous of these in 1940, under the aegis of the Museum of the American Indian (now part of the Smithsonian Institution).
Morde returned from Mosquitia with thousands of artifacts, claiming to have entered the City. According to Morde, the indigenous people there said it contained a giant, buried statue of a monkey god. He refused to divulge the location out of fear, he said, that the site would be looted. He later committed suicide and his site—if it existed at all—was never identified.
They identified a crater-shaped valley, encircled by steep mountains, as a possible location.
To survey it, in 2012 they enlisted the help of the Center for Airborne Laser Mapping at the University of Houston. A Cessna Skymaster, carrying a million-dollar lidar scanner, flew over the valley, probing the jungle canopy with laser light. lidar — “Light Detection and Ranging” — is able to map the ground even through dense rain forest, delineating any archaeological features that might be present.
When the images were processed, they revealed unnatural features stretching for more than a mile through the valley. When Fisher analyzed the images, he found that the terrain along the river had been almost entirely reshaped by human hands. [Continue reading…]
