Wallhausen – Steilwand
At Wallhausen on the Konstanz side of the Überlinger See, the slope west of the harbour steepens into a wall that ends at about 75–80 m. Just past the marker line there is a small planted fir-tree 'forest' with a doll at about 12 m and a surfboard at about 23 m. Further west the wall kinks twice, and about 100 m on lies the 'Klinker', where a boulder jammed between two walls forms a swim-through at 43–50 m. Below the wall a mud slope with erratic boulders and tree trunks continues past 90 m.
depth: 0–80 m
