The Big Stone River is the most interesting sight of Taganai Park in Russia. It is also one of the most wonderful sights in Russia. Different from other rivers, it is filled with rocks and stones. Not a drop of water can be seen. Interestingly, as one comes near to the rocky river, the sound of running water can be heard.
The Big Stone River is about 6 km long and is made up of many small rocky rivers. It cuts through a thick forest like a real river. It is about 200 metres wide and, in some places, it is up to 700 metres wide. Some of the rocks weigh up to 10 tons each and the layer(层)of rocks goes down 6 metres deep.
There are many stories of how it formed. However, scientists point out that none of them may be true. They believe it is the result of the movement of glaciers(冰川)about 10,000 years ago. At that time, ice covered the top of the mountains. As time went by, the ice turned into water.
