Only karst cave of Orlické hory
Orlické hory ("Eagle Mountains") are quite karstless, only local cave has evolved in a pocket of intensively metamorphed limestone thick with flint seams, which was once exploated in a chamber of small underground quarry. The entire underground is about 50m long but continues also somewhere under water level. This inconspicuous place, which is even not on maps, puts a small but important stone into a mosaic of this peaceful borderland mountain range.
