‘Crazy Craters’ Found in Swiss Lake

By: Maria Vargas

In the muddy floor of one of Switzerland’s largest lakes, four giant craters were found. The biggest crater recorded was 525 feet wide and 100 feet deep. According to a doctoral student, these craters are springs. The team used ship-based sonar to search for sediments within the craters. How the craters were formed is still a mystery, however the pits appear to be spitting mud eruptions violently. These mud eruptions leave behind a layer of sediment that resembles to lava flows. However, the last huge mud eruption in that region happened around 1,600 years ago. Now a days, this crazy crater is filled with wet mud. Scientists believe that there is a connection between the mud eruption and the Jura Mountains.  It is believed that there exists an underground network of limestone caves and cracks.
