Have lasers located lost city of gold sought by conquistadors in 1500s?
Underneath the thick, virgin rainforest cover in the Mosquitia region of Honduras, archaeologists have discovered ruins they think may be the lost city of Ciudad Blanca.
Legends say the "White City" is full of gold, which is why conquistador Hernando Cortes was among the first Ciudad Blanca seekers in the 1500s. But the method the modern researchers used was a little different from previous explorers' techniques. The modern-day researchers flew over the area in a small plane and shot billions of laser pulses at the ground, creating a 3D digital map of the topology underneath the trees.
This is one of the first times this technique, called light detection and ranging (LiDAR), has been used to map ancient ruins. Beyond archaeology, LiDAR researchers at the National Science Foundation are looking to develop the technology for mapping disasters using drones, for military spying and for tracking erosion under rivers and shallow parts of the ocean....
