This natural pool, with its rainbow coloured waters, is found in Yellowstone National Park and is the third largest hot spring in the world.
This gayest pool is dangerous due to its temperature. What is the best view? From the boardwalk or an aerial view using a drone. Visit, but do not swim. Learn its depth. How many deaths? Colors caused by bacteria?
