Looking into the deep water source at Tonnerre in Chablis France was mystical. It has a quiet, powerful, mythical secret. Tonnerre is similar to the lake described by Henry David Thoreau:
A most beautiful and expressive feature. It is earthâs eye; looking into which the beholder measures the depth of his own nature.
When we visited and looked into its endless depth we felt it was a place of depth that put us into a state of rapture for the earth's mysteries.
The Fosse Dionne, is a karst spring located in Tonnerre in Chablis in France. It is driven by the infiltration of precipitation on the plateau as well as drainage from at least one river. The Fosse Dionne is remarkable because of its outflow (100 litres per second on average). Its presence is at the center of the creation story of Tonnerre. An elaborate wash basin was built around the spring in the 18th century.
A karst spring includes the underground drainage of a much larger area, which means that karst springs often have a very large discharge. Because of their often conical or bowl shape, such water sources are also known in German-speaking lands as a Topf ("pot").
Karst springs are usually the end of a cave system at the place where a river cave reaches the Earth's surface. Thus, it is often possible to enter the caves at a karst spring and explore them. Large karst springs are located in many parts of the world. The world's largest karst springs are believed to be in Papua New Guinea, with others located in Mediterraneancountries including Bosnia, Turkey, Slovenia and Italy.
