A Lost Mayan City Has Been Found With Laser Mapping
Archaeologists have revealed an ancient lost Mayan city using advanced laser mapping technology, unearthing monumental structures such as pyramids and plazas. Named Valeriana, the city is believed to have been founded before 150 AD.
“The larger of Valeriana's two monumental precincts has all the hallmarks of a classic Mayan political capital: enclosed plazas connected by a broad causeway; temple pyramids; a ball court; a reservoir formed by damming an arroyo (a seasonal watercourse); and a probable E-Group assemblage, an architectural arrangement that generally indicates a founding date prior to AD 150,” says the study, published in the journal Antiquity. “This limited sample was obtained with great effort, with archaeologists painstakingly scouring every square meter, hacking away at vegetation with machetes, only to discover they were standing on a pile of rocks that might have been someone's house 1,500 years ago.” In 2009, archaeologists Diane and Arlen Chase of the University of Nevada, Las Vegas, pioneered the use of lidar to map a Mayan city, revolutionizing the way ancient civilizations are detected and studied.
