| ND8435001 | Dead body on the crib arch | Geomorphological structure and shape |
Tettnang District Tettnang |
47 ° 38 '32.9 " N , 9 ° 34' 57.3" E |
 |
The approximately 120 × 170 meter large and up to 15 meter deep tub in the Tettnang Forest is one of the numerous dead body sinks that pile up here on a strip of terrain running along NS. They emerged in the late Worm Ice Age, when ice floes (dead ice) isolated from the dwindling glacier and embedded in sediments melted and their sediment cover subsided. The kettle basin lies in the gravel of the central Tettnang terrace, a gravel field that was deposited here by a meltwater stream coming from the east during the Worm Ice Age glacier retreat (Konstanzer Stadium).

| ND8435002 | Tobel Lichtengehau | Important layer sequence, geomorphological structure and shape |
Meersburg district Meersburg |
47 ° 42 '2.7 " N , 9 ° 15" 31.7 " E | The north-west Meersburg, which cuts the steep slope to the shores of Lake Constance, has sunk into the Steinbalmensande (Upper Freshwater Molasse) and enables a comprehensive view of the rock formation. In the lower area, the soft, massive sandstone sets in over gray marl (Haldenhof marl). Harder layers cause small waterfall steps. On the southern flank of the ravine, an artificial cave has been created in the sandstone wall on the crossing path. At the top, the ravine intersects the Öhninger layers (OSM).

| ND8435003 | Sand dune near Salem | Geomorphological structure and shape |
Salem district Salem |
47 ° 46 '35.7 " N , 9 ° 17' 54.7" E | The Salem drifting sand dune is part of the remainder of a dune field formerly consisting of 5 walls of sand that was located in E Salem on a gravel surface of the Wurmzeit Rheingletscher. Today only the eastern half of the dunes, lying in the forest (former length around 200 to 1000 meters) are preserved. The eastern part of the former main dune, which is 300 m long, approx. 100 m wide and four to five meters high, is called the Salem dune. Due to their flatter N and steeper S sides, there is a deposit from N winds. Its origin is in the early Holocene and is given as Boreal (- 10 000 years). Geological unit: Quaternary |

The glacier mill is located on a small, flat knoll in the Überlingen district of Brünnensbach , not far from the steep drop to Lake Constance . It is a circular hollow shape, about twenty meters in diameter and up to ten meters deep, deepened in sandstones of the Heidenlöcher layers ( upper sea molasses ). When the glaciofluviatile deposits with which it was naturally filled, it was exposed towards the end of the century before last, in 1984. Geological unit: Tertiary |
| ND8435006 | Rock towers at Rotweiler (7 Churfirsten) | Geomorphological structure and shape |
Sipplingen district Sipplingen |
47 ° 47 ′ 32.2 " N , 9 ° 7 ′ 4" E |
 |
The well-known sandstone needles of the Sieben Churfirsten protrude from the upper NW slope of the Rotweiler Berg, a clod of the Sipplinger Bruchfeld made up of Upper Sea Molasse (OMM). There are five larger, conical columns up to seven meters high. During the erosion, the soft sandstone was preserved under the protection of locally harder layers. In addition, there was probably also the existence of a fissure network favorable for formation. To prevent further disintegration, the top layers of the columns were artificially renewed. Geological unit: Tertiary |
| ND8435007 | Nagelfluh Steinbalmen E Heidenhof | Important shift sequence |
Überlingen district Bonndorf |
47 ° 48 '23.1 " N , 9 ° 5' 37.6" E | A rocky pulpit protruding from the steep edge east of the Haldenhof with a small platform and a steeply sloping wall up to about eight meters high is protected as “stone balms”. The rock forms the westernmost point of a 300 meter long, partly interrupted band of rock, which consists of gravel from the older Pleistocene. These gravel (Pleistocene), which have entered the specialist literature as Haldenhof-Nagelfluh, are up to 15 meters thick and deposit the stone balm sands of the Upper Freshwater Molasse. They represent sediments of a meltwater channel formerly directed towards the Rhine, the base of which reaches different depths into the lying area, as the restless bearing surface shows. The rock is in the vicinity of a geological path. Geological unit: Quaternary |

| NSG8435008 | Bohnenbachtobel | Important layer sequence, special sediment structure, tectonic deformation, geomorphological structure and shape |
Sipplingen district Sipplingen |
47 ° 47 '19.3 " N , 9 ° 6' 51.9" E | The upper end of the Bohnenbachtobel is deepened like a kettle into the layers of the Upper Sea Molasse (Obere Meeresmolasse) and the Kirchberger layers of the Brackish Water Molasse (BM) on top of it and has several, partially over-sintered waterfall levels. A staggered, NE trending and S falling transverse fault causes tectonic shifts. On the eastern flank, a rock wall opens up clearly sloping sandstone of the Upper Sea Molasse with overlying BM (scree horizon and velvet sands of the Kirchberger layers). The outcrops are located on the northern edge of the Sipplinger Triangle, a triangular rupture area, which is characterized by presumably Pliocene faults and Pleistocene landslides.

| ND8435013 | Rock wall with heath holes | Important layer sequence, geomorphological structure and shape |
Überlingen district of Überlingen |
47 ° 46 '31.1 " N , 9 ° 7' 57.6" E | To the south-east of the Brünnensbach district, a rock face about 400 meters long and over 20 meters high forms the steep drop to Lake Constance . Remnants of artificially created caves are called Heidenlöcher. The outcrop profile, which is known as the “locus typicus”, shows massive, soft sandstone, which contains the mineral glauconite and, as so-called Heidenloch layers, forms the lower part of the Upper Sea Molasse. The total thickness of the series is 65 to 70 meters. A vertical running parallel to the lake shore clearly emerges as the main direction of the cleft. In the vicinity of the rocks there are large caverns , some of which were used as production facilities. Geological unit: Tertiary |

| ND8435014 | Gehrenmännles hole | Important layer sequence, geomorphological structure and shape |
Friedrichshafen district of Ailingen |
47 ° 41 ′ 27.8 " N , 9 ° 28 ′ 42.8" E |
 |
The "Gehrenmännles Loch" is a niche cave up to four meters deep, six meters wide and two and a half meters high on the left lower valley slope of the Rotach between Oberailingen and Berg . It originated in a less solidified area of the interstadial gravel of the Würme Ice Age, cemented to Nagelfluh . The ceiling of the erosion cavity is formed by a hard, solidified bench. The fluvioglacial Worm Ice Age deposits, which are exposed with a thickness of around eight meters, are overlaid by a ground moraine from the Worm Ice Age, the so-called “Achen Advance”. Geological unit: Quaternary |
| ND8435015 | Erratic block (ophiolite) from Überlingen | Special rock types and / or minerals, geomorphological structure and shape |
Überlingen district of Überlingen |
47 ° 46 ′ 30.5 " N , 9 ° 11 ′ 12.2" E | The boulder - a stone block with rounded edges and flattened at the edge, three meters long, three meters wide and one and a half meters high - was set up on a green area between the factory gate and the main building of a company at the eastern exit of Überlingen in the direction of Lippertsreute . The green rock with glass-like inclusions and streaks shows clear traces of glacial transport on its surface. The ophiolite comes from the Platta Nappe of the Alps, which is now located in the Julier region (Switzerland) (Pennine Nappe system). This is the former Jurassic ocean floor (oceanic crust), which was lifted up when the African and Eurasian plates collided to form the Alps. The erratic block was found during excavation work about 200 meters east of the current position in the Würm ground moraine, which is stored here above the Lower Miocene sea molasse.

To the north of Markdorf , on the edge between the south-west slope and the plateau of the Gehrenberg, there is the 200-meter-wide demolition niche of the large slide on the Fuchsbühl, which can be seen from afar. This is caused by clays and marls of the upper freshwater molasses, which have a water-retaining effect and which are overlaid by moraine material dating from the ice age. Together with the morphology, the outcrop offers a good insight into processes in current geology. Geological unit: Tertiary |
| 8435012 | Ebersberg near Hinteressach | Geomorphological structure and shape |
Neukirch district Neukirch |
47 ° 41 '4.4 " N , 9 ° 42' 42.1" E |
 |
In the strongly structured drumlin landscape around Neukirch there is a wide hill, the Ebersberg, around 900 meters north-northeast of the village of Hinteressach , which stands out from the numerous moraine walls, drumlins and dead ice hollows in the area. The approximately forty meter high oval hill has strikingly steep slopes and is the result of the most recent ice advance of the Würm Ice Age, north of the hill is an east-west flowing meltwater channel. On the summit, which is now wooded, there are still relatively impressive remains of the former Ebersburg. Geological unit: Quaternary |
| 8435013 | Exposure in Langtobel | Geomorphological structure and shape, important layer sequence |
Owingen District Owingen |
47 ° 48 '27.1 " N , 9 ° 9' 13.9" E | In the elongated wooded ridge between Sipplinger mountain and Owingen (Hochbühlzug) perform some brief but deeply carved ravines to the northeast. One of these ravines is the Langtobel around 700 meters west of Owingen. The Tobelbach opens up a high profile in the tertiary molasse after about 300 m from the mouth upstream on the western steep slope. Stratigraphically, the lower half of the profile belongs to the Upper Sea Molasse, of which about four meters of red-violet sandy marl (flame marl of the sand slate) can be seen first. Above that follow almost ten meters of glauconite sandstones from the Baltringer strata, followed by fine sandstones and above them grayish-red, bulbous-crusty limestones from the Albstein. The approximately 16 meters of marl limestone and marly fine sands above it already belong to the Upper Freshwater Molasse. At the exit of the ravine, the boundary between the sand slate and the layers of heather holes of the Upper Sea Molasse can be seen. Geological unit: Tertiary |

| 8435014 | Kogen gravel pit near Biggenmoos | Important layer sequence, special sediment structure |
Tettnang district Tannau |
47 ° 40 ′ 28.7 " N , 9 ° 37 ′ 24.8" E | In the area of the gravel pit in the Gewann Kogen north of Biggenmoos , a larger delta of meltwater sediments was poured to the north during the crack ice age or early worm ice age. Another glacier advance (Innenwall-Würm) pushed over the delta and the surrounding landscape and formed it around it. In the gravel pit, glacial sedimentary structures are clearly visible. The delta filling is still clearly visible, and there are also block layers. It is a particularly interesting and significant information! Geological unit: Quaternary |
