Shanay-Timpishka
Along the Amazon is a four-mile-long boiling river that can get to near 200 degrees Fahrenheit. The Amazon forest is wild full of natural wonders, including the Shanay Timpishka river. This is not something you'd want to fall into!
Researchers aren't so sure as to why the river is so hot. The nearest volcano is over 270 miles away, but it's possible that it could play a part into the steamy river. If someone tried to go for a swim, you would most likely be boiled alive.
