The Hohenstoffeln (also Hohenstoffel or colloquially Stoffel , from ahd. Stophil , small rock ) is a mountain of volcanic origin in the Hegau between Binningen and Weiterdingen . It belongs to the basalt group of the Hegaus. The mountain has been a nature reserve since 1941.
The Hohenstoffeln is the only Hegauberg to have a double peak . The mountain originally had three peaks, but the northernmost one was eroded by basalt mining. The southern peak has a height of , the northern (formerly middle) a height of .
The Hohenstoffeln was the location of three castles. Hinterstoffeln Castle was on the north summit, Vorderstoffeln Castle on the south summit and Mittelstoffeln Castle in the saddle of the mountain.
Further below the summit are some farms: the Stofflerhof on the west side towards Binningen , the Sennhof and Hombollhof on the east side near Weiterdingen and the Pfaffwieser Höfe on the south side towards Hilzingen .
The geomorphological and geological structure of the Hohenstoffeln consists of Deckentuffen with vorbasaltischen Tuffmassen. In addition to basalt, there is also bentonite (Swiss type). At the summit, thick, vertical basalt columns are visible.
Since the beginning of the 20th century, basalt has been mined for road construction at the northern summit, as the rock is tough and hard and has no preferred cleavage direction so that it does not weather quickly. The broken rock was transported to the gravel works in Mühlhausen via a four-kilometer cable car.
The local poet Ludwig Finckh advocated the stop of basalt mining, in fact it was stopped from 1939. The former quarry can still be recognized by the mining terraces.
Already in 1904 the basalt mining was criticized by the conservationists. After years of confrontation, inspections and disputes, the summit of the Hohenstoffeln was declared a nature reserve in a letter dated August 24, 1935 - the 750 m height line was the limit :
"Regardless of its mining use within the above-mentioned limits and careful forestry use ( plenter operation ), the Hohenstoffeln is classified as a." According to Sections 12 (2), 13 (2), 15 and 24 of the Reich Nature Conservation Act of June 26, 1935 (...) Nature reserve entered in the Reich Nature Conservation Book. "
On December 23, 1938, a telegram from the Konstanz district office reached the Süddeutsche Basaltwerke, operator of the basalt quarry on Hohenstoffeln:
"Quarry operations closed on the instructions of the highest nature conservation authority on December 31, 38. Infringements come under threat of punishment under Section 21 of the Reich Nature Conservation Act. Due to other accommodation of the workers and processing of the material already obtained and because of the necessary clean-up work, further disposal is reserved. "
"Reichsforstmeister Generalfeldmarschall Göring has decided that the most stately of all Hegau mountains, the two-peaked Hohenstoffeln in the western Lake Constance area, will be placed under nature protection with the cessation of any further basalt mining and will be entered into the Reich Nature Conservation Book as a protected area."
In May 1941, the mountain was registered as a nature reserve in the Reich Nature Conservation Book. The importance of the mountain for the landscape, geological , plant sociological and ornithological reasons were particularly emphasized in the entry.
