The Abismo Oscuro (Dark Abyss Cave) is a rather difficult vertical cave, which is used for cave tours recently. The tours are operated by FossilLand, a socalled Parque tematura, a "theme park" offering various outdoor experiences, like canyoning, climbing, driving quad, and even caving. They are located at the farm of Otto von Schroeter. His father came here from Germany to make a living by farming and quarrying the limestone. The current owner has transformed the fantastic landscape caused by this small outcop of limestone with its rocks and canyons into this new venture. This is on one hand not very good for the environment as the human imnpact increased. On the other hand the operator keeps the place clean and stopped the quarrying o fthe limestone.
The Fossil Land Complex is located on a 6km² big, fossil rich outcrop of limestone and contains six caves. Beneath the caves there are various other karst features. The bioclastic limestone with abundant fossils is of Miocene age (15 Ma). Most common are fossils of Pecten sp., large scallops or saltwater clams which are commonly known as the logo of the Shell oil company.
Abismo Oscuro (Dark Abyss) is also known as Captain Tula's Cave and Patarrá Pit. This cave is pretty small and actually its just a 20m deep shaft with two or three platforms. In 2000 the film crew of the Channel 6 documentry Repretel ("The Explorer") visited the cave. They needed a lot of electricity for there lamps so they brought their fuel driven power generator into the cave. This was a pretty poor idea as the exhausts of the motor soon filled the cave. Beneath other oxidation products, motors typically produce carbon monoxide, which is a fine way to commit suicide. The film crew had to be rescued from the cave.
Today the cave is developed by three long metal ladders. So it is possible for all physically fit and free from giddiness visitors to see the cave, even if they do not know caving techniques. But it is also possible to rappel and climb out using the single rope technique (SRT). The tours into the cave include an introduction into caving and take three hours.
