State Capitals Meet Time Zones

I love it when categories collide and take me in entirely unanticipated directions. That’s what happened today. I noticed an interesting external search that bounced against my site: “What 2 state capitals are within 20 miles of a time zone boundary?” I’ve featured time zones many different times. I’ve also focused on the peculiarities of states. However I’ve never linked the two together so I decided to investigate this query further.

This should be pretty straightforward, I thought. Mapquest displays time zone markers and Google Maps provides a Great Circle distance utility. It shouldn’t take much effort to find the answers by toggling between the two.


Pierre, South Dakota

Pierre, the capital city of South Dakota is the obvious initial choice that jumps right out (map).

I can’t find a handy map with the proper licensing to embed here. Fortunately, many examples can be found all over the Intertubes with your favorite search engine.

Pierre falls in Central Time. But a bridge over the Missouri River is all that separates it from Western Time. Perhaps the town on the western bank, Ft. Pierre follows Central Time informally (don’t know that for a fact but such affinity recognition is fairly common). Even it that’s the case it’s hard to imagine a scenario where Pierre doesn’t falls within 20 miles of a time zone boundary both formally and informally.


Juneau, Alaska

The second state capital is a bit more problematic. However, I think it’s supposed to be a trick question with the answer being Juneau, Alaska. Usually people tend to overlook Alaska and Hawaii in these types of trivia questions. So they are an obvious choice for early consideration. [UPDATE: it does indeed seem to be Juneau. See the comment provided by a knowledgeable reader below]

Again, understand how time runs here. In this case it happens to follow an international border, separating Juneau in the Alaskan Time Zone from British Columbia and Yukon in Canada, both following Pacific Time. There’s only one problem though: the distance is about 35 miles.

Maybe the person looking for the information got the question wrong? Perhaps that’s the case, but then consider that Bismarck, North Dakota is about the same distance from a time zone boundary or maybe even a little bit closer (about 32 miles – hard to tell). I never realized it before but there are other state capital cities located fairly close to time zone boundaries too. Examples include Tallahassee, Florida at about 42 miles and Atlanta, Georgia at about 57 miles.

So Pierre, SD is a no-brainer. The second part of the answer is either Juneau, AK, or Bismarck, ND. Or perhaps some other state capital that I’ve overlooked. Nonetheless it was a fun exercise and I hope our searcher finds his or her answer.


Down the Rabbit Hole We Go

I mentioned at the beginning that Google Maps has a utility that provides Great Circle “as the crow flies” distances between two points. It’s a useful tool, and in case you haven’t seen it before you can find it easily enough from their front page by following these links in succession:

  • My Maps
  • Featured Content
  • Distance Measurement Tool

I guess I’ve been feeling a little more curious than usual lately and I happened to spot the “I’m feeling geeky” option. Well, I’m often feeling geeky so I gave it a shot. There are a whole lot of units of measurement available that one can use to describe the distance from Juneau, AK to the Canadian border, whether useful, sublime, obsolete, or bizarre. 1145.28 Olympic Swimming Pool lengths, anyone?

    The second answer is, in fact, Juneau. In 1970, the city of Juneau merged with the surrounding borough, meaning that the city limits now extend to the Canadian (and time-zone) border, even though the populated area is where the star appears on the map.

      So it is a trick question using the usual Alaska answer. Outstanding! Thank you for solving the mystery.

    Hey, just came across your site, definitely one of the best ones I’ve seen, and filled with topics that fascinate me. Never thought I’d find someone that loved looking at maps and loved geography this much!

    You are correct in your guess that Ft Pierre, while technically in mountain time, chooses to observe the same time zone as its larger neighbor of Pierre. I stayed here for a night on my cross country road trip.

    This geographic anomaly does come in handy the locals told me, as the bars and strip clubs on the Ft Pierre side are legally allowed to stay open an hour “later” than the bars in Pierre! Just a quick trip over the Missouri River!

      The power of the Internet — small groups of people with a singularly quirky hobby can actually find each other and see that they’re "not alone." I visited your website and thoroughly enjoyed reading about your cross-country road trip. It reminded me of a similar trip I took soon after finishing school way back in the Dark Ages before the Web took off. I took the southern route but I did cross a few of the same spots you recorded. I’ve been slowly scanning all those old paper-based photographs I recorded during my trip and I hope to post something similar to what you’ve done when I get a little free time. I placed a teaser on the Twelve Mile Circle a few weeks ago, a story I called: I jumped the border.

    Oh wow, haven’t come across your post about your trip yet, still going through everything else since I just found this! It definitely looks like we hit a bunch of the same spots. You’re probably mad that I didn’t go to the 4 corners (from what I read this seems to be one of your favorite places). I’ve always wanted to see it, ever since I was little and discovered it myself on a map. While I was nearing the southwest region in late April 2009, I heard on a local radio station that the 4 corners monument was found to inaccurately placed, and therefore I didn’t even think it was worth the time to go 5 miles out of my way, and instead kept heading to monument valley. Obviously I later found out that this was basically a hoax, and it is indeed accurate. Oh well, just a reason to do another trip!

    I would have to say, the time zone line near Juneau is “near, yet far away.” It is literally impossible to get to the time zone line by car, boat, or even on foot. I have been to Juneau and took a scenic flight over the mountains. The terrain is extremely rugged, with glaciers and sheer cliffs. Also, there are few town on the Canadian side anyway, so the time zone line doesn’t really matter, as opposed to Pierre, SD where you just cross a bridge.
