Karlova špilja is a cave in Zagorje about 14 metres (46 ft) long, located on the north slope of the Ivanščica massif. It is a dry horizontal cave with a passage length of 8.5 metres (28 ft). It is difficult to access, but a tourist path has been planned. Its close proximity to the Šumec cave and paleolontological potential have made it a target of interest for local speleologists and paleontologists.
Description
Like Bračkova špilja and Voska luknja, the cave is located in the ravine of the Šumec, which cuts through the Dubrava peak. It is horizontal, wider at the entrance than in the passages. There are two passages from the entrance. The passage on the right narrows and remains unexplored. The passage on the left is longer is longer but narrow and ends with an impassible widening. All passages are only accessible by crawling, but digging may widen them and has been recommended in conjunction with archaeological investigation.[5]
A map of the cave was drawn in 2012 by Tomica Matišić exists.[5]
History
Cavers from the HSS section Kraševski Zviri discovered the entrance in March 2010. The cave was mapped in July 2012.[4]
Climate
The air temperature of the cave is 12 °C (54 °F), with a soil temperature of 13 °C (55 °F). The relative humidity is 86%.[3]
Geology
The cave is situated in Middle Triassic dolomitic limestone. Speleothems include coralloids and flowstone.[4]
Biology
The moth Scoliopteryx libatrix and cricket Troglophilus cavicola have been found in the cave. There is minor biowaste hazard in the cave from its continued use by a small predator, likely a fox, and the restricted space.[2][5]
Tourism
A tourist path has been planned from Šumec to Bračkova jama and Bračkova špilja, and from there to Voska luknja and Voska špilja, then to Šumec cave and Karlova špilja, then to Generalka and Polušpilja Generalski Stol.[6][7]
