One twelvemonth ago , a squad of researchers traveled deeply into the Honduran rain forest in hunt of Ciudad Blanca , the fabled lost city of gem . Yesterday , they let on figure of speech — uncovered by laser — ofstructuresthat they conceive to be the White City itself .
The caption of the White City has trance Internet Explorer ’ imagination for centuries ; Hernán Cortés detailed his interest in the purportedly gold - laden city as far back as 1526 . But the Mosquitia part where it was rumor to exist is obtusely packed with rainforest , and the conquistadors never imbue deep enough to exact their prize .
New archaeologists have been just as embarrass . Mosquitia has been the focus of a half dozen intensive explorations in the last century alone , some of which have yield sign of some ruins and mounds . No one , though , despite their best feat , had recover anything close to a full city structure .
The team of investigator from the University of Houston , though , had something none of those military expedition did . They had optical maser .
Major Laser
The National Center for Airborne Laser Mapping does just what you would opine ; use highly ripe optical maser to see things the human eye ca n’t . Specifically , in this case , the squad — direct by a Los Angeles - based movie maker — used a Lidar system to penetrate the compact foliation of Mosquitia and discover the treasure that lay beneath .
Lidar itself is n’t in particular unexampled . develop in the 1960s , it was originally used to measure swarm densities , but comes in ready to hand today for everything from mapping theAmazon rainforesttohunting downmodern - day pirate . In this implementation , the system spits out laser heartbeat and measures how they ’re reflected off botany and the ground , to map the control surface hidden beneath the timberland ’s canopy .

By stripping away layers of reflection the researchers were able to off detail from the canopy and bring out the primer below , record on the right in the image above . Yesterday , the researchers revealed these imagesfor the first metre , at the American Geophysical Union Meeting of the Americas in Cancun .
The White Cities?
After others had spend centuries try on to excavate a single city of Au , the NCALM geographic expedition made a surprising find : not one city , but two .
It might hard for the untrained eye to see , but the Lidar images revealed regularly spaced hammock — and a few other linear feature — that possibly make up two distinct city center . Either of which could very well be the legendary Ciudad Blanca .
We should know soon enough . The team is now closely studying the datum to work out which sections contain the most promising features . Once they have , they ’ll deploy archaeologists to look into the site further .
What will they happen ? Maybe rubble . Maybe amber . Maybe 1000 ofinexplicable prosperous orbs . The theory are sempiternal when you unveil a caption right here in tangible lifetime . [ Nature ]
