LIDAR uncovers new structures near Machu Picchu

January 27, 2022

Researchers using LIDAR at the site of Machu Picchu in Peru at the nearby site of Chachabamba, where elite groups had to stop to purify themselves in a sacred bath before entering Machu Picchu, have uncovered 12 structures, and stone channels, some underground, supplied water to people in the area. They are able to map how the water was channeled to the sacred baths.

The scientists used a type of remote-sensing technology known as light detection and ranging, or lidar, which bounces laser pulses off surfaces to detect features and map their contours. 

The team from Wroclaw University of Science and Technology in Poland and Peru’s Ministry of Culture used drones with LIDAR to peer through the forest canopy. The researchers will return to the area after COVID subsides in the region.

The research is published in the Journal of Archaeological Science.
