Via the Nerdist: “In 1944, Harold Fisk had been following ghosts for three years. His ghosts were of the meandering Mississippi. A river, big or small, doesn’t stay still – as its waters flow it carves out new paths in a route towards its ultimate destination. Over time, the bends and curves of what seems like a static river snakes into new outlines. By looking at the geologic evidence, you can even map many of the paths a river once took – like looking at the past lives of the waters, the river’s ghosts.”
