Meandering River Map: Color Usage in Cartography




Rivers are incredibly dynamic and powerful feature that greatly influence their surrounding landscapes. From the Colorado Canyon carving deeper down into the Grand Canyon, to the ever meandering Mississippi River, it is easy to forget how these features influence the landscape over hundreds of years.

The above map is of the ancient paths of the Mississippi River, and through the colors and forms drawn, the cartographer tells an incredibly dynamic tale of how this famed river has meandered over time.

At first the red classifications boldly capture the viewers eye, introducing us to the dynamism of the Mississippi River. But notice, red is the only bold color choice and is broken up by the more subdued yellows, oranges, and blues. After the red curves so fearlessly dare us to gaze upon this image, those oranges, yellows, and blues begin to tell a deeper story of the Mississippi River's wandering path. Finally, after allowing the eyes to inspect each curiously colorful elongated curve, the center of the map reveals where this adventurous river had settled at the time the cartographer crafted this map.
