Archaeologists have recently found lost Mayan cities deep within the Guatemalan jungle using remote surveying technology. They have found nearly 60,000 structures showing the extensive architecture of the Mayans. This new discovery revealed the technology used by the Mayans for agriculture and also gave more clues on the demise of the empire. Researchers have used a new piece of technology called LiDAR (Light Detection and Ranging) which uses laser to find hidden objects inside heavily forested areas. Experts believe that this technology can help uncover more data on ancient civilisations around the world. After the new findings, archaeologists believe that there are hundreds of Mayan cities yet to be discovered.
