Daniel Huffman has created a series of maps of rivers in the abstracted style of subway maps.
“I don’t think people are used to seeing and thinking about rivers this way — realizing their interconnectedness, their importance in the establishment of settlements, or the fact that they were humanity’s original transit networks. It’s not something I’m ignorant of, but I don’t think about rivers like this regularly. I’ve lived in cities that are on rivers without ever noticing. Rivers … to me are often just those thin blue lines lost in the background of a lot of reference maps.”
