Description

Hydrology

Because of its position along the main joint direction, only about 1 km from the current end of the Blauhöhlensystem, membership in that system is likely. Markers from a dye tracing experiment, introduced directly into the water of the river cave, could be clearly detected in the Blauhöhlensystem and in the Blautopf.

Other details

As of March 2025, the Steebschacht, at −166 m, is the deepest cave of the Swabian Alb.
