Under the snowcapped mountains of Fiordland National Park, freshwater streams empty into the saltwater fiords, creating a unique ecosystem. This is a heavily wooded park, so the water in the streams is stained with tannin, a substance found in plants that makes clean water seem dirty, though it isn't.
