Epecuén, Argentina is an old tourist town that spent more than a quarter of a century underwater. Established in the 1920s on the banks of a salt lake, the town was home to over 5,000 residents and a holiday destination to thousands more.In 1985, it flooded and buried the town in 33 feet of salt water, rendering it a modern-day Atlantis. Initially, people waited on their roofs, hoping for the water to recede. It didn’t and the place was a devastated ghost town.
