I've put all of my findings about the limits of U.S. time zones (past
and present) online at http://www.statoids.com/tus.html. It's all
verbal description. For example:
> * Idaho county split (Idaho state)
> I have a northern and southern part of Idaho county, which I got from
> another timezone map (possibly Manifold map). This indicates that the
> southern part of Idaho county is on America/Boise time while the
> northernpart is on America/Los_Angeles.
I have "Idaho county north of the Salmon River" on Pacific Time.
> * Sioux county North Dakota
> Tz database states "part of Sioux county" and that is exactly what

I have "Sioux county west of ND route 31" on Mountain Time.
