Dauner Maars
In contrast to the previous picture (which shows a crater lake) here you can see three typical maars. A maar is a broad, low relief crater that is caused by a phreatic eruption or explosion caused by groundwater contact with hot lava or magma. They have a typical "hole in the ground structure" sometimes surrounded by a wall composed of a mixture of loose fragments of volcanic rocks ejected during the explosion. Maar (latin mare: sea) was first introduced by geologist and teacher Johannes Steininger (1794 -1878) from Trier who used this term (from the Dauner dialect) for this water filled volcanic funnels. Now the term is also used in the international scientific terminology.
