"In 1879, [adventurer and geologist John Wesley] Powell proposed that 'as the Western states were brought into the union they be formed around watersheds, rather than arbitrary political boundaries.'"
This map shows what America would look like if it followed its watersheds. It's an America designed to use water more efficiently, and reduce state conflicts over water. Think state conflicts over water aren't a big deal? Then you don't know that Georgia, Florida, and Alabama are engaged in a massive battle over their water sources.
