Discover the HIDDEN Coastlines of North America from the LAST ICE AGE

Between 15,000 and 10,000 years ago, enormous ice sheets blanketed much of North America. So much water was locked in these glaciers that the oceans shrank, exposing land that is now long gone. What is today the continental shelf — the wide, shallow platform that rings the Gulf — would have been dry land during that time. It’s easy to look at a modern map and forget just how different the Americas looked 15,000 years ago. But at the height of the last Ice Age, the Gulf of Mexico, or Gulf of America, or El Gulfo de Mehico, whatever you like to call it, wasn’t the expansive, warm sea we know today. It was narrower, shallower, and surrounded by vast coastal plains that are now buried beneath over a hundred of feet of ocean water.
