World external link This are links, which leave
We try to add as many external links as possiblle, especially if there exists an official site, which means a site made by the owner of the cave. We mark them with a small planet Earth symbol, which tells you that this link will lead you to the rest of the world....
In the last years several strange judicial decisions made it necessary to point out the following: We are linking only to sites about caves, mines, geology, and sometimes tourist sites. However, we have no possibility to ensure the content of pages that are not maintained by us. It may always have changed since our last visit.
By following any link leading out of this website, you accept, that is not responsible for the content you may find.
Book book The book symbolizes a Literature link.
We tried to list as many interesting books about the topic of this site as possible. A link with the book logo will lead you to the named book.
