Schwarzsee in the Hellbachtal

The Hellbachtal near Mölln is one of the most valuable parts of the Lauenburg Lakes Nature Park in Schleswig-Holstein. The nature reserve is around 157 hectares and includes the valley and valley edge areas of the Hellbach, Lottbach and Mühlenbach from the southern part of the Drüsensee in the north to the Gudower Mühle in the south. The Lottsee, Krebssee and Schwarzsee lakes are included in the nature reserve .

The valley of the brook lies within the geologically very young sand area , which was in front of the glaciers of the Vistula Ice Age . The brook flowed through a 20 to 30 m deep channel, which includes numerous lakes and clearly differs from the landscape surrounding the valley. This incision begins at Gudow on Sarnekower See and ends at Mölln, where it joins a wide valley with the Drüsensee and Lüttauer See .

The Hellbachtal was created by an early advance of glaciers. A meltwater drainage lying under the ice had dug deep into the ground and created a subglacial meltwater channel, a so-called tunnel valley . Due to the comparatively slow thawing time of the Mölln- Gudower glacier , the valley was not buried by the sands of the later Ratzeburg glacier . The dead ice blocks of the old glacier were covered by the sand, but after they had melted they released the old valley floor again.

The three small lakes in the valley, Schwarzsee, Lottsee and Krebssee, are remnants of so-called whirlpool holes, which are also known as pools . The ponds were in the stream of the Ice Age tunnel valley.

The boggy valley provides a protected home for numerous animal and plant species. Here you can find rare dragonfly species and the sand lizard, which is threatened with extinction in many places . The now rare adder lives here in dry, warm niches. On the connected to the southernmost point of the glands lake fen meadow bloom in early summer, among others, marsh marigolds and counting to orchids Broad orchid .
