One of them reminds us of the turbulent geological periods, in the time when the relief was renewing, meaning, it says a lot about the creation of the deep river basin of Crna River. It tells a story of a certain fight between two monsters (some sort of dragons), which during the fighting broke a part from the mountain somewhere in Mariovo and in that exact path the Crna River simply started flowing.
Actually, the legend speaks about a time of formation of the Skochivir Gorge, which is one of the longest and most attractive gorges which divides Mariovo on two halves and makes this area exceptionally attractive. This gorge, which is 80 kilometres long, the largest part – 59.5 kilometres spreads through Mariovo.
The other legend is connected to its current name which, according to the legend, comes from the fact that this river is wild and it flows though some playful and drifting area, and it swept in blackness one mother each day, taking away one child, due to which it is called Crna (Black) River.
