Joey, actually the blue line on the National Geographic map doesn't depict a river whatsoever, it's an arbitrary color for a state border.

Because the river actually IS the defining border for the state, on the Imus map the river is highlighted in blue underneath the dark-green that depicts a state border.

A much better design decision IMO.

Oh, I had assumed the darker purple outer border on the Natgeo was the blue of the river. Wow, that's bad.
