2012 posts several updates on the underwater site off the coast of Cuba.
“Manuel Iturralde, research director of Cuba’s Natural History Museum, has joined Canadian exploration company Advanced Digital Communications (ADC) in efforts to solve the mystery of the smooth, geometrically shaped, granite-like rocks. They are laid out in structures resembling pyramids, roads and other structures at more than 600 meters deep (2,000 feet) in a 20 km-square (7-3/4 mile-square) area.”
