FISK Mississippi River maps

Inspired by... the FISK Mississippi River maps. Isn't this map incredibly gorg? In 1944 cartographer Harold M. Fisk made a geological survey of the ever shifting Mississippi River for the U.S. Army Corps of Engineers. This masterpiece, and dozens more like it from various parts of the river, are the result. He and his team did a huge amount of research on the history of the river course, tracing 20 "stages" of the river course going back some 2000 years. Each color represents the geological route the river had taken throughout the centuries. You can see more of the Fisk maps here, and you can actually download the full sized maps for free from the Army Corps of Engineers!
