Changes in sea level have allowed a Stone Age site to stay exceptionally well-preserved below the surface of Hanö Bay in the Baltic Sea. Researchers at Lund University in Sweden believe the site was a lagoon environment where Mesolithic humans lived during parts of the year. Seven years previously, divers discovered the oldest known stationary fish traps in northern Europe at the same location. This discovery, along with new findings including a 9,000-year-old pick axe made out of elk antlers, indicate mass fishing and a semi-permanent settlement. The settlement has now been mapped comprehensively for the first time.
