Hinanger waterfall
The Hinanger waterfall is a geotope south of Sonthofen in the Oberallgäu district . The Hinanger waterfall is made up of several rock steps, over which the Hinanger Bach overcomes a total difference in height of over 25 m. The actual waterfall has a fall height of 12 meters.
geology
On the east side of the Illertal , the Hinanger Bach falls over a steep step that was formed from solidified fluvioglacial gravel . The formation of this gravel is related to the geological development of the area during the Ice Age . The so-called Iller foreland glacier transported large amounts of gravel, rock rubble and fine-grained material from the Alps to the northern foreland. At the edges of the glacier, the material was piled up in the form of moraine walls. Due to the uplift of the Alpine foothills during the Ice Ages and the simultaneous progressive erosion by the Iller, step-like graded gravel terraces were formed, which can be assigned to different cold periods, whereby the older gravel terraces are today on the valley flanks in a morphologically higher position than the younger gravel, which are the broad ones Fill in the valley floors. In this by ballast and mineralization of pore water solidified dirt, the cut tributaries Iller partly clammy like the moraine - as here at Hinanger waterfall - one.
The carbonate-rich stream water, which was mineralized by a chemical reaction of the carbonated rainwater when it seeped through the calcareous gravel, forms the porous tufa at the waterfall with the help of site-specific plants . The mosses and microorganisms remove carbon dioxide from the stream water trickled down at the waterfall, and wafer-thin lime deposits are excreted, which combine to form a loose, porous framework. Various sinter basins have formed in the stream bed below the waterfall .
A site-specific tufa flora has developed in the vicinity of the waterfall . In addition, there are numerous in the river valley rhododendrons and dwarf bellflowers that their main distribution above the timberline possess and here on the creek water in much lower habitats were transported. Other plants that are adapted to the rocky, moist subsoil, such as butterflies , rock cinquefoil and rock valerian , can also be found in the immediate vicinity of the moist water cascades.
The geotope Hinanger waterfall has been classified by the Bavarian State Office for the Environment as a geoscientifically valuable geotope (geotope no. 780R035). The geotope is accessed by a hiking trail .
