The Jankovac waterfall—or Skakavac— drops nearly 30m, and creates special rock formations, one of the main types is 'tufa' (porous limestone). It is formed as mineral-rich water loses carbon dioxide and minerals settle. Natural mosses and algae help in this case. Tufa is still growing today, making it one of Papuk’s youngest rocks. Some layers are about 6,000 years old, showing the park’s recent geological activity.
