Many of the world's rivers are an incredible sight to see. If you came across a river that looked like the one seen here, you might think that a river can't get much better than this. But you would be wrong.
By being close to proximity to the volcano, the water has a high concentration of minerals. In particular, it has high amounts of copper sulfate, calcium carbonate and sulfur. According to this one theory, the minerals chemically reacted to produce a turquoise color.
According to their research, the thing making the water appear turquoise isn't the water itself. Instead, it's the rocks on the bottom of the river. And this is because they are coated with a special substance.
Further research showed the difference has to do with particle size. In the Good View River, the particles of the substance are about a third of the size of those in Rio Celeste. And that difference in size is all it takes for the Good View River to not have the same color.
