Imagine this: flying over Zagreb’s beloved Jarun Lake and spotting a dark, clearly defined hole at the bottom! No, this isn’t a scene from a horror movie, but a real phenomenon that has sparked curiosity and social media buzz. Jarun, with an average depth of about four meters, hides a secret – deep, irregular depressions not marked on official maps. One such spot reportedly reaches a staggering 13 meters deep! How is this possible? Well, this area used to be a gravel excavation site, and years of gravel extraction have left deep pits at the lake’s bottom. Geologically, the lake is fed by underground waters flowing through gravel layers, adding complexity to the mystery. This mysterious hole isn’t just a strange sight; it’s fueling speculation and concern – what exactly lies beneath the surface of our favorite recreational spot? Is it a natural phenomenon or the result of human activity? While experts continue to investigate, citizens keep guessing. Thought you knew everything about Jarun? Think again! So, what do you think – a natural mystery or a consequence of human neglect? Drop a comment, maybe together we’ll uncover what’s hiding beneath that dark hole!
