フェンダースハイムの天然記念物・トップ20

The Aulheim Valley lies within the Flonheim district in Rheinhessen. Geologically, Rheinhessen largely corresponds to the Mainz Basin, the northeastern edge of the Upper Rhine Graben. When the Upper Rhine Graben collapsed millions of years ago during the folding of the Alps, a connection was created via the Rhone Valley to a subtropical sea in the south and via the Hessian Depression to what is now the North Sea. This led to two flooding phases in the Oligocene and Miocene. The Vorholz Peninsula was only briefly flooded. The floor of the Mainz Basin consists of rock formations from the Rotliegend or Permian periods (296–251 million years ago). There was volcanic activity here from fissure volcanoes that covered the surface with layers of lava. In the Aulheim Valley, the lava was fast-flowing, low-silica lava, which cooled quickly and solidified into porous sediment with numerous gas inclusions. This made andesite unsuitable as a building material. Water and minerals penetrated the inclusions, and after the water evaporated, agates and geodes slowly formed. On the path through the Aulheim Valley from the Geistermühle to the Aulheimer Mühle, you can still see the retaining walls of the slope on the side facing Flonheim. Boundary stones can still be found here, marking the old district boundary.

There used to be a coast here but that was a few days ago! 😉

Nature is taking back bit by bit!

「Ockenheimer Hörnchen」には平和の十字架があります。そこでは定期的に追悼の焚き火が行われていたため、第二次世界大戦の犠牲者を追悼するために1952年に追悼と平和のための十字架が建てられました。 Quelle: https://ockenheim.de/mahn-und-friedenskreuz/

There was once a sea here 30 million years ago. The Rheinhessen coastal path provides insights into different coastal shapes in various rock outcrops.

Lavishly designed rest area with a beautiful view.

A great place with one of the most beautiful views of the Rhine Valley, Rheingau, Ockenheim etc.
