“Long before the ancient Maya built temples, their predecessors were already altering the landscape of Central America’s Yucatan peninsula. Using drones and Google Earth imagery, archaeologists have discovered a 4,000-year-old network of earthen canals in what’s now Belize. The findings were published Friday in Science Advances. ‘The aerial imagery was crucial to identify this really distinctive pattern of zigzag linear canals’ running for several miles through wetlands, said study co-author Eleanor Harrison-Buck of the University of New Hampshire. The team then conducted digs in Belize’s Crooked Tree Wildlife Sanctuary. The ancient fish canals, paired with holding ponds, were used to channel and catch freshwater species such as catfish. ‘Barbed spearpoints’ found nearby may have been tied to sticks and used to spear fish, said study co-author Marieka Brouwer Burg of the University of Vermont.” (11/25/24)
