Boiling River

In a rainforest in the heart of Amazonian Peru, scientists believe they have discovered the world’s largest thermal river, running hot for nearly four miles and reaching up to 80 feet at its widest point and 16 feet at its deepest. While the river’s extreme temperatures are not unusual for a geothermal surface, it is deemed remarkable in that it is non-volcanic. The nearest active volcanic area is actually more than 430 miles (700km) away. The so-called ‘Boiling River’ is said to be the “crown jewel” of an unusual collection of three non-volcanic rivers in the area which also include the Salt River (a salty thermal stream) and the Hot River (a thermal freshwater stream) - both much smaller in comparison to the Boiling River.
