State Border Anomalies

A collection of small, odd state boundary features. The maps below are linked to the specific area on Google Maps to get a wider perspective. Links to the town names generally discuss why the particular feature exists, but for the most part they are the result of survey lines meeting geographical features in unanticipated ways.

The town of Southwick, Massachusetts extends two and a half miles into Connecticut along the boundary establish in 1804:


Southwick, Massachusetts

A small western portion of Virginia cuts back eastward into West Virginia. There is even a smaller bulb extending off that with a neck only 200 feet wide near the unincorporated community of Wyoming City:


Hurley, Virginia

The far western portion of Kentucky contains a polyp extending off Tennessee around a segment of the Mississippi River known as The Kentucky Bend:

New Madrid

The village of Beecher Falls, part of the town of Canaan, Vermont, juts like a dagger into the northern reaches of New Hampshire. This is perhaps my favorite one because of all the time I’ve spent looking at maps of this region, I never even noticed this until a couple of years ago:

So did you find all these yourself?

As a kid, I liked “geography puzzles” such as: Which is further west, Reno or Los Angeles?

Yes, I’ve noticed these over the years and had always been meaning to collected them all into one place. It’s a testament to my obsession with maps or something like that…

You should add Carter Lake, Iowa. It’s a little neighborhood just outside of downtown Omaha, NE that is for some reason part of IA. It’s odd. You’re driving through Omaha headed towards downtown and all of the sudden there’s a welcome to Iowa sign on the wrong side of the Missouri River.

Take a real close look at Salem County, New Jersey (near the Delaware River). The State of Delaware has land on the right bank bank of the Delaware river in two areas connected to Salem County, New Jersey.

What about the (former) state capital of Illinois known as Kaskaskia? It is now WEST of the Mississippi.
