Germany - Lake Tuttensee (2015)



Lake Tüttensee in Bavaria has been the subject of controversy for many years. Some claim that it is created by glacial activity, the other that it is a crater after the impact of a meteorite. The aim of this scientific expedition was therefore to verify which of the theories is right. We measured several linear profiles west and southwest of the lake. We started the first profile in the meadow and over the ramp we drove with 6 m long antennas up to the summit wall about 20 m above the lake - further dense forest.


The radarogram shows an almost horizontal line of the original surface (white arrows) and obliquely inclined layers in the wall area. These could have arisen from landslides and weir through a much higher mound by rainfall. In the right part of the picture you can see changes in the structure of dolomite up to the depth of 60m.
Another profile ended about 50m from the lake and even on it you can see the gradual layering over the straight interface.
According to the measured data, it seems that the mounds in the western part may be ejected after the impact of the meteorite.
