That nature is surprising is shown by the perfectly shaped stone spheres, discovered accidentally underneath the hill Grljevac in Velika Kladuša. For now three have been “discovered” – the largest one seven meters in girth and weighing 2500 kilograms, a smaller one weighing 1200 kilograms with a girth of three and a half meters, and the smallest one girth of 52 centimetres and 600 kilograms. Because of the shape and composition, as well as the unusual space where they were discovered they attract attention also the mystery of whether they’re natural or manmade pique our interest. For discovery of this oddities from Velika Kladuša the members of the Mountaineering Association of Velika Kladuša are responsible.
President of the Association Šefik Sadiković says: “Though the first spheres were located two years ago, no one knew about them nor spoke about them. Only now, when we located these three did we speak publicly about it. Spheres were located in a creek which created a large canyon due to plentiful rain. Locals of Zborište found the spheres and they drove one into the village using a tractor.” That’s how the story about this phenomenon started.
We are sure that there are more of them in this area, the mountaineers made sure that geologists get the spheres. Geologists Ševket Goletić and Senad Karajić determined that “underneath the spheres a “floor” of the same structure as the spheres was found which means that they haven’t been moved since they were created, and that floor gives greater certainty when determining the way they were created.”From the Jurassic period
“First estimation direct”, Ševket Goletić believes, “that the spheres come from the Jurassic period and that they were created underneath the surface of the sea. That’s why man has nothing to do with the creation of this phenomenon. That period of creation is called Initial Geosynclinal volcanism, which means that they were created around 30 million years ago.”
“It is known that in this region the Panonian sea was present and that it receded seven million years ago, which means that the spheres were created deep underneath the sea due to volcanic action. During eruptions of the volcano rocks in form of lava were expelled in the sea depths, which created additional blasts and chunking, and with the influence of water and sudden cooling this spherical shape was created covered in a manganese veil which gave the spheres additional firmness”, he adds.
According to the first estimations, the content of these rocks is made out of more elements: titan, zircon, vanadium, barium and nickel, which points to the sediment origin from the basic rocks. The surface is smooth and perfectly polished, and it is hard to assume that they could be a work of man which at the time possessed primitive tools. Otherwise, Goletić and Karajić recall, similar spheres were found in other areas as well.
“So”, they say, “they’re numerous in western Mexico, but they’re also located in Bosnia and Herzegovina. Mostly around Zavidovići. And they’re most similar to the ones located in Zavidovići. They’re also located near Stari Majdan in municipality of Sanski Most in the north-western part of BiH.”Mysterious spheres
Mountaineers say that the spheres were most likely “discovered” earlier, but no one spoke of them. It is assumed that the legends and stories imposed a type of silence. One that, for the people living in these areas – spurred the imagination of the inhabitants about the mysterious spheres.
One of the legends says that the spheres are actually eggs of an ancient dragon and according to folk belief we shouldn’t disturb them. That’s where the answer to the question of why no one spoke about them lies. However, out of curiosity the inhabitants broke them, and determined that the interior is made out of stone. Certain findings say that they were brought home, namely the parts of the sphere. Even built in the foundation of the houses. Later they would be unearthed and placed back to their original location.
In these numerous legends, stories and speculations, there is a theory which claims that they’re meteors which fell a long time ago in this area or that they’re the work of some ancient and unknown civilization. However, mountaineers from Velika Kladuša sought help and analysis of the Mining-geological faculty from Tuzla. While they’re waiting for an answer and debunking of the mystery about the creation of this phenomenon – they went into action.
