Native language + English language = Dillingham Accent? WTF?

Why do Dillingham residents have an accent that's unique to only Dillingham? I've been to many parts of Alaska and have seen many different types of people. There's one thing I've noticed with most villages where English at one point in time was not the primary language. Guess what? They all seem to have pretty much the same "Native accent". No matter where you go, it's the same. Dillingham seems to be the only exception. Why? It's not only Natives that have it here, it's whites also. I know someone that lived in the Naknek area about 20 years ago who moved to Dillingham. Within five years this person (white) had the "full-blown DLG accent". I know other people who have moved away from the Dillingham area and they still have this accent (with you for life, apparently).

I guess you're in it, you're around it, you're going to be it. Eventually. Simple as that, huh? What I want to know is WHY Dillingham's is so different. I have a pretty good idea, and I'm going to stick with it.

Back in my younger days, some of my friends would talk to each other in "up-river natiff", as they referred to it. They didn't speak Yupik, just pretended like they were barely learning English. Ever hear "quit making that face, it's gonna stay that way?" Well these guys would catch themselves speaking in thier "new pretend language" without realizing it.

With that in mind, I'm convinced that this 'Dillingham accent' was accidentally started at someone's party over the weekend decades ago. The party goers couldn't 'catch & stop' themselves with their new accent. It then spread like wildfire throughout Dillingham. The rest is history.

Anyone out there have a better idea?
