I'm looking for nice examples of the influence of natural or political boundaries to dialect divergence for introductory purposes. Generally through some limitations on the ability of people to interact. I know there are many out there, but it would be nice if it was one that has been well described and illustratable with an image. Maybe Swiss dialect diversity or Rhineland vowel shift pockets?

2What part makes a difference interesting for you? Geographical features leading to dialect/language difference are most of everything. British vs American English? Sicilian vs Calabrian? Lots of maps showing the difference between the American Southern accent and the more Northern. Do you really just want political boundaries?– MitchNov 15, 2016 at 18:21

1There are phonetic differences in the dialect of North Saami spoken in Guovdageaidnu correlated with Norway / Finland. The cause though is not the border or a geographical feature, it's the fact that the countries have different national languages, so speakers in Norway also speak Norwegian and speakers in Finland also speak Finnish – the cause is different L2s, not political boundary. You mean like that?– user6726Nov 15, 2016 at 18:28

1The Alps are a good natural boundary, each valley has it own dialect. Ladin dialects follow the Dolomite valleys, Alemannic on a larger scale follows many natural boundaries.– Alternative TransportNov 15, 2016 at 22:09

1I would line it up with this map, or a similar one upload.wikimedia.org/wikipedia/commons/thumb/f/fc/… Maybe insert both into GIMP and set the language map to 50% transparent and crop it so it shows mainly Switzerland.– Alternative TransportNov 15, 2016 at 22:24

1This map shows inhabited towns in Switzerland, and gives a good impression of how isolated some valleys are. blog.tagesanzeiger.ch/datenblog/wp-content/uploads/sites/32/…– Alternative TransportNov 15, 2016 at 22:33

I understand that Korean is the prime example of this. South Korean is more open to loanwords, particularly from English, while North Korean was subject to changes stemming from the Juche ideology.
In the 1920s, the Japanese linguist Hattori Shirō wanted to investigate local dialects. At the time, the two most notorious dialectal areas in the region were Tokyo-style or "Eastern", and Kyoto-style or "Western" Japanese. The two areas differ in vocabulary: For example, the copula "to be" in Tokyo is da, while Kyoto prefers ya. They differ in grammar: for example, to conjugate the verb taberu, "to eat", into the negative, "not eat", Tokyo goes tabe-nai while Kyoto uses tabe-hen. And they differ in pitch accent patterns; in Tokyo HAshi means "chopsticks" and haSHI means "bridge", while in Kyoto it's the other way around. But Hattori wanted to map out precise borders, so he took the train, and stopped at every stop to talk to people and listen.
Turns out that exactly up to the east margin of the Ibi river in Mie one finds Tokyo-style pitch. Cross the river and people on the other side clearly talk in Kyoto pitch.
This was surprising to everyone because people to the east of Ibi (in Gifu and Aichi) used Kyoto-style grammar and vocab; before Hattori's research, people thought they spoke "Western (Kyoto-style) Japanese". To put it another way, if you come from Tokyo you'll find a mixed "buffer zone" east of Ibi where the pitch is still Eastern (Tokyo) style, but word choice and inflections are already Western-style.
Hattori explained this as follows. In modern times Tokyo is the prestige, standard dialect, and it's easy to find Kyoto natives who adopt Tokyo-style words and grammar; however, they hardly ever manage to change their pitch accent. (One reason is that the "accent classes", i.e. the groups of words with the same melody, do not match between dialects; so that you can't predict how will the pitch change in the other dialect). To put it simply, pitch is more resistant to the standard. It's easy to imitate the rules of the prestige grammar, or to borrow the words of the standard lexicon; but it's hard to change the tones of every single word.
And it so happens that, for most of Japanese history, the standard dialect was Kyoto, not Tokyo (i.e. the opposite of today). The fact that the Kyoto pitch falls neatly along the Ibi river must show that it spread up to this natural/cultural barrier, and stopped. The fact that the people east of the river have a Tokyo pitch shows that they must have been originally Tokyo-style speakers; they've managed to absorb Kyoto grammar and vocab, but couldn't absorb the pitch.
These observations have inspired Robert Ramsey's bold theory of the history of Japanese pitch, which in turn has proved to be quite productive. (The picture above, a translation from Hattori's, is from the linked article.)

Full disclosure: I'm working on Ramsey's ideas under De Boer; this subfield is still controversial. My senior colleagues have advised me to pay attention to things like rivers and mountain ranges when doing fieldwork, and always ask informants where they grew up; because there were cases where an unexpected pitch pattern was explainable after learning that some guy who "is from here" actually came from across some river.

Some examples for the German language (with links to maps!):
The word Jause is an Austriacism and is rarely found outside the Austrian borders.
The word Broiler still reflects the boundary between Eastern and Western Germany; note also the word Poulet being restricted to Switzerland, Alsace, Lorraine and Luxembourg on the same map.
Also the word Topfen is becoming more and more an Austriacism, loosing ground in Bavaria to Quark.
Lower level boundaries between different states of Germany can be seen in this map: Different states of Germany use different terminology for written school exams. Here, Bavaria is sticking out.

thanks, @jknappen, exactly the sort of thing i was looking for and very nice maps to illustrate it! :)– puslet88Nov 15, 2016 at 22:08
What about looking in to Serbo-Croatian? It was considered one language under Yugoslavia, but now is considered multiple languages.
