In 1879, surveyor (and future USGS director) John Wesley Powell proposed that the boundaries of future western states be determined by watersheds, in order to avoid water use conflicts. John Lavey takes this proposal to its logical conclusion, imagining a U.S. in which all 50 states follow watershed boundaries. Via io9.
Another data point for our consideration of what people think a fantasy map looks like, from the author of the Maptitude tumblelog: a fantasy map of Ireland, replete with, as you would expect, forests and hills. It departs from the fantasy map paradigm by using colour: red for political boundaries, blue for water. It also uses a vaguely uncial script: something we’ve seen in the movie versions of The Lord of the Rings, but less often in fantasy book maps. Not inappropriate for Ireland, though.
Fantasy maps have a very specific style that is actually quite limiting. For an example of what would happen if all maps were subject to the same limitations as fantasy maps, have a look at what is described “a map of the United States à la Lord of the Rings”; it was posted to Reddit and edited there by divers hands. The version above had the gridlines removed and made more “antique.” It does look like the early Middle-earth maps done by Pauline Baynes and Christopher Tolkien. To match the movie maps, you’d have to replace all the text with overdone uncial calligraphy and Tengwar vowel marks, whereas maps in modern fantasy novels would lose the shading on the mountains and have all the text done in Lucida Calligraphy.
