Mirror Lake + Underground Forest
That's a picture taken from a ship. Mirror Lake is the attraction of Mudanjiang. It is formed after volcanic eruption. The lake is deep and still just like a mirror. The color of the water is green.
It is near Mirror lake, at the northern end of it. It's not quite wide but in the shape of Niagara Falls.It has a fall of only 12 meters high and more than 40 meters wide. It is formed after volcanic eruption. The rocks are dark just like coals and the water in the pool is dark green. In winter the waterfall will change into an ice curtain.
