Meander Maps of the Mississippi

In 1944 Harold Fisk published a series of beautiful looking maps of the Mississippi River. In his 'Geological Investigation of the Alluvial Valley of the Lower Mississippi River', commissioned by the Army Corp of Engineers, Fisk not only mapped the flow of the Mississippi but also tried to represent how the river's course has meandered and changed over time.

Fisk's maps use a number of different colors to show the different courses of the river over the centuries. You can view static images of all fifteen of Fisk's maps for the Army Corp of Engineers on this radicalcartography post.

Some of the Army Corp of Engineers' later meander maps of the Mississippi River can also be viewed on Meiotic's Meander Maps. Meiotic has geo-referenced a few of the Army Corp's maps and placed them on top of modern maps and aerial imagery of the river's course. These maps include a slider control which allow you to compare the Army Corp's original maps with a modern map of the river.

Luckily Somebits has also geo-referenced all 15 of Fisk's original maps. The 1944 Map Of Former Courses of the Mississippi stitches all 15 maps together. Unfortunately the modern aerial imagery seem to be broken on this interactive map. However you can still compare Fisk's map to a modern map of the Mississippi and you can use the interactive map controls to zoom-in and study Fisk's beautiful maps in loving detail.
