Archaeologists find previously unknown structures among Machu Picchu’s ruins

The Machu Picchu discoveries, which include parts of a water system that ran through the area, are yielding new insights into Inca civilization and the role of ceremonial complexes at Machu Picchu.”Only very privileged people could get to Machu Picchu, because it was a very special place,” said Dominika Sieczkowska, the deputy director for organization and development at the University of Warsaw’s Center for Andean Studies, who led the research.”When you were going there, you had to stop in Chachabamba for a spiritual bath to be clean and pure to get to Machu Picchu.” Video: Explore Antarctica’s treasures, including visit with Emperor penguins (TODAY) Kim Potter sentenced to two years in prison for killing of Duante Wright US gas prices could spike if Russia invades Ukraine, analyst says Biden ‘convinced’ that Putin will invade Ukraine Best Fan Friend Friday: 2 friends win a TV from Hoda and Jenna!

The lidar scans revealed about 12 structures all within about 60 feet of the main ceremonial part of Chachabamba.”They were so close, and we didn’t even know they were there,” Sieczkowska said.

The laser scans also revealed stone channels running partly underground that supplied water throughout the Chachabamba site.The researchers then developed models based on the slope and depth of the canals to re-create how water may have flowed to the various ritual baths.Sieczkowska said that much remains unknown about how the newfound structures around Chachabamba were used but that they may have been residences for people who oversaw the ceremonial site.The archaeologists plan to conduct further research at Chachabamba, including excavations of interesting features that were identified in the lidar scans.”The idea was to excavate some of the structures, but because of the pandemic, we had to cancel our plans for now,” Sieczkowska said.”But maybe, maybe, we’ll get there next year.”.
