We are a union of speological friends from the Ruhr district, which are committed to the cave and nature protection.

Even if we did not unite under a fixed legal form, we cooperate already many years continuously together.

Since we do not rank among to the large associations we are glad to cooperate with friendly groups and associations, in order to be able to implement the common interests more effectively.

Our activity emphasis belongs not only to caving, but also the study and documentation of artificial cavities.

As goes out out of our name, our activity area is situated primarily in North-Rhine/Westphalia, we operates however also on projects beyond the national boundaries.
