Untersee (Lake Constance)
The ''Untersee'' (German language, German for ''Lower Lake''), also known as Lower Lake Constance, is the smaller of the two lakes that together form Lake Constance. The boundary between Switzerland and Germany runs through it. The lake surrounds several islands, the largest being Reichenau Island. Geography The Lower Lake Constance measures and is situated about lower than the Obersee (Lake Constance), Obersee. The Roman Empire, Romans called it ''Lacus Acronius''. In the Middle Ages, the Upper Lake was called ''Bodamicus Lacus'', or ''Bodensee'' in German. At some point in time, this term began to include the Lower Lake, and a new term "Upper Lake" (in German: ''Obersee (Lake Constance), Obersee''), was introduced for the larger lake. The main tributaries are the ''Seerhein'' and Radolfzeller Aach. The source of the latter is the Aachtopf, a karst spring whose waters mainly derive from the Danube Sinkhole, making the Danube indirectly a tributary of ''Untersee'' and ...

Lake Constance
Lake Constance (, ) refers to three bodies of water on the Rhine at the northern foot of the Alps: Upper Lake Constance (''Obersee''), Lower Lake Constance (''Untersee''), and a connecting stretch of the Rhine, called the Seerhein (). These waterbodies lie within the Lake Constance Basin () in the Alpine Foreland through which the Rhine flows. The nearby '' Mindelsee'' is not considered part of Lake Constance. The lake is situated where Germany, Switzerland, and Austria meet. Its shorelines lie in the German states of Baden-Württemberg and Bavaria; the Swiss cantons of St. Gallen, Thurgau, and Schaffhausen; and the Austrian state of Vorarlberg. The actual locations of the country borders within the lake are disputed. The Alpine Rhine forms, in its original course ( Alter Rhein), the Austro-Swiss border and flows into the lake from the south. The High Rhine flows westbound out of the lake and forms (with the exception of the Canton of Schaffhausen, Rafzerfeld and Bas ...

Bodanrück
Bodanrück () is the wide peninsula that divides Lake Constance () into '' Überlinger See'' (part of '' Obersee'') and '' Gnadensee'', which is part of '' Untersee''.

The '' Markelfinger Winkel'' separates it from the Mettnau peninsula. The nature reserve Wollmatinger Ried lies at the southern shore of Bodanrück.

Danube Sinkhole

Translation: "Sinkhole – Here the Danube sinks dry on about 155 days per year" The Danube Sinkhole ( or ) is an incipient underground stream capture in the Upper Danube Nature Park. Between Immendingen and Möhringen and also near Fridingen ( Tuttlingen), the water of the Danube sinks into the riverbed in various places. The main sinkhole is next to a field named ''Brühl'' between Immendingen and Möhringen. The term "sinking" is more accurate than "seeping", because, instead of just distributing into the soil, the Danube's water flows through caverns to the Aachtopf, where it emerges as the river Radolfzeller Aach, a tributary of Lake Constance and the Rhine, respectively.

Karst Spring
A karst spring or karstic spring is a Spring (hydrology), spring (exsurgence, outflow of groundwater) that is part of a karst hydrological system. Description Because of their often conical or inverted bowl shape, karst springs are also known in German-speaking lands as a ''Topf'' ("pot") which is reflected in names such as Aachtopf (the source of the Radolfzeller Aach) or Blautopf (the source of the Blau (river), Blau river in Blaubeuren). Karst springs often have a very high yield (hydrology), yield or Discharge (hydrology), discharge rate, because they are often fed by underground drainage from a large catchment basin. Because the springs are usually the terminus of a cave drainage system at the place where a river cave reaches the Earth's surface, it is often possible to enter the caves from karst springs for exploration. Large karst springs are located in many parts of the world; the largest ones are believed to be in Papua New Guinea, with others located in Mediterranean ...

Aachtopf
The Aachtopf () is Germany's biggest karst spring, south of the western end of the Swabian Jura near the town of Aach, Baden-Württemberg, Aach. It produces an average of 8,500 litres per second. Most of the water stems from the River Danube where it disappears underground at the Danube Sinkhole, north near Immendingen and about north near Fridingen. The cave system has been explored since the 1960s, but as of 2020 only a small part has been discovered due to a large blockage after a few hundred metres. Etymology The name Aachtopf is compounded from ''Aach'' (meaning "water" in Old High German); ''Topf'' can be translated as "bowl" and is commonly used for round, bowl-shaped springs. Geography The Aachtopf is a karst spring, south of the western end of the Swabian Jura near the town of Aach, Baden-Württemberg, Aach.

Hohentwiel 07
Hohentwiel () is a mountain of volcanic origin in the Hegau region of Baden-Württemberg in southern Germany. It is the ''Hausberg'' of the industrial city of Singen, located west of it and ca west of '' Zeller See'' (Lake Constance). The ruins of the medieval Hohentwiel Castle rest on top of it. Hohentwiel was an active volcano about 7–8 million years ago during the Miocene epoch, along with several other volcanoes in the Hegau region. It mostly consists of phonolite, which represents the former volcanic pipe. The surrounding softer rocks have been eroded over time by ice age glaciers during the Riss glaciation, creating an inverted relief and giving the mountain its present-day shape. Naming etymology The first written accounts of Hohentwiel Castle are held within the St. Gallen monastery chronicle of Ekkehard IV (circa A.D. 980-1060) as "castellum tuiel", which was reportedly besieged in 915. In the Late Middle Ages, the name of the castle evolved from "Tuiel" to "Twie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
