I’m not sure what the significance of this is supposed to be. On any given day, there will be a whole line of points where the Sun rises at the same point as at any given point. And what that line is for each point will vary through the year, so you can’t even absolutely state that three particular points are on the same line.

The significance is that the sun rises at exactly the same time even though they are at different longitudes, which is a little cool, at least.

But at the solstices, when the full 23 1/2 degrees of the Earth’s tilt is away from the sun, wouldn’t the terminator span a considerable longitude?

A slight tangent, but I’ve always found the term midwest to be misleading, seeing as how it’s largely in the eastern half of the country. Likewise Northwestern University is not where you’d expect it to be.

The Northwest Territories (starting in what is now Ohio and extending west) were originally in the northwest of the US. The US simple got bigger most relevantly with the Louisiana purchase.

Yeah, and Connecticut claimed the norther part of it, and a lot more. The original Connecticut grant was for a strip of a certain width from sea to sea. The colony was forced to surrender that part in Pennsylvania but claimed the rest and that part in Ohio was known as the Western Reserve. The federal government intervened and Connecticut ceded its claim west of Ohio in return for the government assuming the Connecticut Revolutionary war debt. Final adjudications of the whole things wasn’t made until 1805.

Yeah, I guess so, but it’s more or less a straight line, which is less cool.
C’mon, I’m sure you guys get it.
Here’s one I noticed on Google Earth: a straight line (great circle) passing through the centre of Paris (Notre Dame cathedral) and the centre of Athens also passes straight through the centre of another capital city, Bern in Switzerland. There are other such triples that come within a few miles, but this one is virtually exact, according to Google Earth.

If it’s caused solely by the relative altitude of the three sites – surely, there are a few other mountains in the world, some of them higher than Mount Washington. That would mean that this kind of thing is so common as to be unremarkable.
Indiana traditionally calls itself the “cross roads of America.”
Indianapolis is called the “cross roads of Indiana.”
In fact, though, most Indiana roads are fairly cheerful.

HUGE! The City of San Francisco is only 7 square miles.
EDIT: To those who can’t beleive there are palm trees in Ireland, they are indeed all over Belfast in the cold north. But from another thread, I beleive they are a sort of “fake” palm.

ahemmm they are not fake. They are new zealand cabbage trees that dont mind the cold. Probably our most successful export since kiwi fruit.

But the City of San Francisco and the County of San Francisco have the same geographic extent: they have the same boundaries, so they have the same area.

The Democratic Republic of Congo, India, Algeria, and Argentina are all larger than Greenland. India is almost 150% of Greenland’s size.

As a young geography major I remember being blown away by the fact that Greenland’s size on maps was purely a result of projection. I felt so…lied to.

More correctly: The District of Columbia was originally ten miles square. (The order is very important here.) “Ten square miles” means an area that’s equivalent to a rectangle 1 mile by 10 miles, or 2 miles by 5 miles, or 3 miles by 3 miles 1760 feet.

My guess is that wherever this factoid is from, it’s referring not just to points that happen to share a sunrise time, but rather, these points are the first to see the sunrise in the United States - Eastport being right on the US/Canada border on the Maine shore, Mt. Washington being the tallest point in the NE, and Mt. Cadillac the tallest point in America within 50 miles of the coast (if I remember correctly from my visit some years back). If their sunrise times really ever match up, I’d be interested in seeeing when that is.

[/QUOTE]
You probably aren’t remembering correctly. Perhaps it’s the highest point within 50 miles of the east coast, but there are much higher mountains that close to the west coast. Mt Cadillac is only 1530 ft; the Olympic Mountains in Washington state (for example) have numerous peaks several times that elevation and are easily within 50 miles of the coast.
As far as the simultaneous sunrise at three different points, this almost certainly only happens during a limited time period each year.
