I’m sure there must be some basic guidelines somewhere as to how much territory is included in the I-95 Corridor or the Mississippi Valley, but I wonder how much we think about that sort of thing.
My mind gravitates toward maybe 50 miles either side of a river and maybe 30 miles either side of a major road.
How do you relate to those terms and concepts?
I live in an actual valley; I don’ t know how wide it is, but not more than a few miles at its widest point. From where I sit I can see the eastern side of it and if I turn around and look out the front I can see the western side. It’s maybe a couple of miles wide at this point, as a WAG.
And yes, we have a river, but it’s far far smaller than the Mississippi.
For a major road I would think 5 miles at most. I mean, I’m 80 miles from the closest interstate, but even a few miles north of it it feels like it is a million miles away. In a heavily populated area this may well be different, but I don’t think “corridor” extends very far to either side.
The most liberal definition of a river valley would probably be it’s watershed, or all the lands drained by it. Of course, using this definition means that the Mississippi River Valley includes most of the upper midwest, so it may not be useful for all applications.
Quite so. I just get the impression, with little else to go on, that the weather people have some idea in mind when they use that expression and assume their intent is clear to viewers. It’s not clear to me, sorry to say. “Corridor” is less clear to me. Definitions I’ve seen don’t even reference roads so much.
