“We often think of rivers as following a given path for the course of its life, but really, the path changes over time as the flow cuts into the earth. The water flows through old and new and back again. In 1944, cartographer Harold Fisk mapped the current Mississippi River. It’s the white trail. Then Fisk used old geological maps to display old paths. They’re the old colored paths. And what you get is this long run of windy, snake-like things.”
