Is that true? It seems like there's water everywhere in northern Minnesota, including many marshes and swamps. I don't know how geologists and map-makers can determine that the Mississippi River goes no farther north than Lake Itaska. It doesn't seem credible.

On the other hand, mining runoff can destroy freshwater lakes and rivers anywhere. I live in Pennsylvania where pollution from old mines has ruined much of our natural aquifer.
