Description

Morphology

The cave is 1071 m long and has an elevation difference of 31 m. It is located in the basal limestone of the Middle Devonian Hobraeck beds and was formed by the dissolution of Devonian limestones. Dolines and pings occur in the surroundings of the cave.

Speleothems

There are hardly any sinter crusts. Aragonite mineralizations occur.

Hydrology

A water-retaining claystone layer in the hanging wall prevents the infiltration of seepage water.

Other details

The cave is scientifically supervised by the AKKH. The walls of the cave were cleaned around 2020/2021.

History

The Aggertal-Höhle was discovered around 1773 and has been a show cave since 1930.
