Summary:
An unusual and unexpected discovery: on the floor of Lake Neuchatel, geologists have happened upon huge underwater craters -- some of the largest in the world to be found in lakes. They are not volcanic in origin, but were caused instead by giant freshwater springs.

Anna Reusch, a doctoral student at ETH's Geological Institute, was utterly amazed one morning: during a routine measuring run with her research vessel on Lake Neuchâtel, she suddenly saw an unusual shape on the control panel screen. Beneath the boat, at a depth of over 100 metres, had to be something no one had ever seen before. She immediately informed her professor, Michael Strasser: "We've found something that you absolutely have to see."
An initial rough data analysis on board indicated that Reusch and her colleagues were looking at a scientific sensation: an enormous crater, measuring 10 metres deep and 160 metres in diameter. "I'll remember this day for a long time -- I never expected anything like this," recalls Reusch, adding: "It just goes to show that even in the 21st century, there are still thrilling and exciting discoveries to be made in Switzerland!"
