Wollenloch

Wollenloch is the name of two natural shafts near Oberkochen on the Swabian Alb in Baden-Württemberg . They are registered as extensive natural monuments .

Big wool hole

The Große Wollenloch (→ Lage) is located on the Wollenberg (710 m) about 3.3 km southwest of Oberkochen at an altitude of 690 m above sea level. NHN. It penetrates about 54 m into the limestones of the lower rock limestone formation of the White Jura and is one of the deepest natural shafts in the Swabian Alb. A direct connection with the Ziegelbach spring near Königsbronn could be established with contrast water studies . On the surface of the earth, the two to six meter wide shaft tube is widened in a funnel-shaped (dolphin- like ) shape as a result of marginal breakouts and has a diameter of about 18 m here. The depth of the wool hole decreased as a result of the rock breaking out, earlier this was given as 62 m.

The Großer Wollenloch was once open to tourists, but this was stopped in the middle of the 20th century after a fatal accident. On October 23, 1949, the fastening hook of a passenger elevator bent and the wire cage fell 45 m. Entry has been prohibited since 1954, and climbing is only permitted with a special permit. Today the mountain rescue service occasionally exercises in the Großer Wollenloch. The shaft is secured with a high wire fence.

Little wool hole

The Kleine Wollenloch (→ Lage) is located four hundred meters east of the Großer Wollenloch a little lower on the slope of the Wollenberg. It is a natural shaft around nine meters deep in the White Jura with a diameter of two to three meters. The shaft is secured with a wooden fence and marked with a green sign indicating a natural monument .
