“I want my money back!!!”

The Four Corners, a famous and popular tourist spot in the American Southwest, is and isn’t where it should be. Confused? Read on.

Four Corners — the only place in the United States where four state boundaries come together — was first surveyed by the U.S. government in 1868, during the initial survey of Colorado’s southern boundary line. Its intended location was an even 109 degrees west longitude and 37 degrees north latitude. However, due to surveying errors, it didn’t come out that way.

According to readings by the National Geodetic Survey, today’s official marker sits at 109 02 42.62019 W longitude and 36 59 56.31532 N latitude. That means the current monument marking the intersection of Utah, Colorado, New Mexico and Arizona is approximately 2.5 miles west of where it should be. According to three different Internet sites for distance calculations (including an FCC site and GPS visualizer) the readings were 2.493; 2.484; and 2.499 miles. A member of the Utah Association of Geocachers in Price also came up with 2.5 miles by using two other Internet sites, Google Earth and the Great Circle Calculator. (Geocachers routinely rely on GPS data to find exact locations.) The true location would be downhill to the east of U.S. 160 in Colorado and northeast of the San Juan River as it flows into New Mexico.

Four Corners Monument is open year-round, 8 a.m. to 5 p.m., except Thanksgiving, Christmas and New Year’s Day. Entrance fee is $3 per person.

But what’s a couple of miles between states?

    OOPS!

    So if i’m “carrying” when i walk around the four corners monument – i’m not guilty of interstate trafficking?

    I read a book recently that was all about how the States got their shapes. Surveyor errors were very common. Some of those disputes have lasted into the modern era. Wasn’t it in the 1990′s that New Jersey won a case in which they claimed that the land around Ellis Island is actually NJ and not NY because the original deal was that everything under the water at that point was NJ and just because NY built up the island, that area was still officially NJ?

    No problem, until something of value is discovered in one state that is actually in another. Then the fur will fly. Hoe it happens soon. Should be entertaining.

    #5. Nothing but sand, coyotes, and prarie dogs. Oh and rattlers.

  7. Rocketeer says:

    So now everyone that went there and took photos for keepsakes will now have to throw them away… they’re useless.

    Easily fixed, just redraw the statelines. problem solved! :)

    Survey was very difficult, especially in the frontier, in the 19th and early 20th centuries. Survey errors are very common. That’s why in most places, the law is that the official survey exists only on the ground and can only be officially defined by a licensed land surveyor.

  10. AshA says:

    Close enough for Government work. . .

  11. jescott418 says:

    I suppose the orgional error on the survey was +/- 2.5 miles. Oh well, its close.

    Since the onset of the drought in the Southeast last year, Georgia has been fighting with Tennessee to move its border 1.1 miles north so that it will have access to the Tennessee River and its water.

  13. DixonAgee says:

    I’m sure it’s pretty common. They used manual survey techniques back in the day. Even modern GPS depends on the mathematical model of earth shape and benchmark. NAD27 vs NAD83 and all that. The corners of California are off, too. They decided not to fix it long ago because it would affect many things – such as gambling establishments in Lake Tahoe.

    So your saying that the picture of my mother sitting in the center of that circle, doesn’t prove she has a butt big enough, to cover four states?

    Dang nabit!

  15. ArianeB says:

    Actually, the state lines were eventually adjusted to fit the marker. The border between Utah and Colorado, and between Arizona and New Mexico is set at 109 02 42.62019 W, rather than 109 W.

    Trivia question: What President of the US is responsible for creating the borders so that the four corners would match up?

    A: Abraham Lincoln – one of his less famous actions.

  16. ArianeB says:

    Actually, it is easy to understand how they got the latitude nearly perfect, but the longitude off. by a few miles.

    Before accurate tools, latitude and longitude was determined by protractor, sundial, magnetic compass, and a book of charts of the suns position.

    Latitude, requires getting the date right, Longitude requires getting the time right too.

    Since gps has become commonplace tons of surveying errors have shown up. Moreover, some of the original deeds to things were woefully vague with some deeds saying the the property was “a hundred yards from the stump on old man Smith’s farm” or something like that.

    Ah, I see the problem now… intelligent design.

    Now comes the class action lawsuit for false advertising and fraud. Gonna refund all those $3 fees which, after the lawyers take their cuts, will be about a buck and a quarter.
