Bozkovské Dolomite Caves

PARTS OF THE BOZKOV CAVES THAT ARE INACCESSIBLE TO THE PUBLIC

Although the tour route in the Bozkov Caves leads through the most interesting places of the system, it is only one third of the total length of all spaces known today. In the large part of the cave, which cannot be seen by visitors, there are tight and complex cavities and passageways. For example Bludiště (Labyrinth) in Staré jeskyně (Old Caves) is formed by crannies among clusters of rock blocks and fallen ceilings, and is difficult to overcome even for an experienced speleologist. Nevertheless, the reward for their effort can be a view of a special type of pisolite decoration that cannot be found in other parts of the caves. The most extensive part of the system that is not accessible to the public is the cave complex of Vánoční jeskyně (Christmas Caves) and Novoroční jeskyně (New Year Caves), which was discovered in the 1960s and 1980s. Here, undisturbed by technical works, well-preserved unique modelling of the cave spaces including clay and debris fillings are found, which must have been cleared out from most of the route that is open to the public. Exquisite foliaceous and leaf-like structures of siliceous layers prepared by selective corrosion emerge here together with places covered with very fine crystals of aragonite. Other relatively extensive parts of the system are situated below the underground water level and thus they are completely flooded. These spaces were discovered by cavers in 1986 near Mládežnický dóm (Youth Dome) and Jezerní dóm (Lake Dome). During long-term pumping and gradual reduction of the water level they descended through the system of shafts and smaller chambers to a depth of 14 m below the normal water level. At present, however, these parts are flooded with water again.

Speleological surveying of the Bozkov Caves is still in progress and therefore every year several metres of new spaces are discovered.
