Rio Solimoes and Rio Negro Confluence: Amazon

No where else will you see a law of science being broken so flauntingly by nature itself. The place where Rio Solimoes and Rio Negro mix, well, actually only meet, has become a tourist destination for an unnatural spectacle of nature. The dark Colored Rio Negro flows into the cream colored Rio Solimoes but both the rivers are completely distinguishable due to their different color that don't get intermixed. Not only is the color different the Solimoes and Negro waters also differ in temperature, nutrient and oxygen content.
