8. The boiling river of Shanay-Timpishka
In the amazon lies a calm river that is distressfully frightening. Shanay-Timpishka is so hot that it can boil you alive. The temperature gets as high as 91C (196F) and scientists are not sure why. Normally hot rivers and lakes are fed by volcanos, but this one is more than 700 kilometers away from the nearest volcano!
When an animal steps into the water mistakenly, it is boiled immediately. Eyes of the animals melt in the skull. Before animal get swim to safety, the water fills his body and his lung, cooking him up from inside. It is a really bad river to slip and fell into.
The most plausible theory states that heat from earth’s core escapes through thin cracks and lines. The heat reaches the river and the water heats up. However, there is no explanation as to how such a thing can even happen.
