Map of the Week-River Systems

Last year, I featured a map from London's Waterways, using a Harry Beck London Underground inspired schematic.  Cartographer Daniel Huffman has created a beautiful series of schematics for various river systems here in the USA. Below is the Mississippi River System.

Details about the creation process can be found on his blog. Prints can be purchased here. Here are some nice detailed views from the series.

Thanks to Cartogrammar for the heads up.
