For thousands of years, the water of Korana and Slunjcica, Croatia, and their flora and fauna fought the laws of nature, and as a result of this struggle in the limestone plateau, a remarkable canyon was carved in. Seeing this natural phenomenon, this "poured off" ("rastocen") terrain, a place where the water of river Slunjcica pour off in several backwaters, leaving behind small elevations which then form watercourses and waterfalls, people built a village and named it Rastoke.
