Twelve-Mile Circle

As a wee lad I grew up south of Downingtown, Pennsylvania, an old mill town situated along the banks of the East Branch of the Brandywine Creek. Drop a little stick in the Brandywine and it would float downstream until it joins the Christina River in Wilmington, Delaware and thereafter shortly into the Delaware River.

Delaware has tax-free shopping and movie theatres I frequented in my youth. First laptop purchase for university? Delaware. Furniture for moving out to Chicago? Delaware. In other words, when I posted my most recent map of where I have been, the three counties of Delaware were some of the earliest counties filled in.

Delaware—for better or worse—is seared into my mind. If you look at the state border, you will see the northern border is circular. Look at all other state borders and that circle is kind of weird. Most other borders are straight(ish) lines, mountain ridges, rivers, or bays. The reason is the border between Pennsylvania and Delaware was, essentially, taking out a protractor and drawing a circle twelve miles distant from New Castle, Delaware, the original capital.

Anyway, I have not thought about that in quite some time. But thankfully, xkcd did.

As many of you know, I love geography and so I am aware of many of these places. Lake Manicouagan is one of those places that has an island in it, which has a lake on that island, in which there is another lake. There might even be another island/lake combination, but I could be mistaken.

Happy Friday, everyone.

I am a graphic designer who focuses on information design. My day job? Well, they asked me not to say. But to be clear, this blog is my something I do on my own time and does not represent the views of…my employers. I think what I can say is that given my interest in information design—be it in the shape of clear charts, maps, diagrams, or wayfinding systems—I am fortunate that my day job focuses on data visualisation. Outside of work, I try to stay busy with personal design work. Away from the world of design, I have become an amateur genealogist and family historian. You will sometimes see that area of work bleed into my posts.
