Four Corners marker 21/2 miles off? Too late
47 comments | Read story
(I rode my motorsickle out there on a HOT late-summer day. It was interesting. The most memorable thing about the trip was the HUGE quantity of discarded bottles and broken glass all along Highway 160, sparkling in the desert sun. I've never seen so much glass litter!)
And as for the marker being off, that's fine. Every boundary in North America shifts by at least a centimeter each year due to plate tectonics anyway. So even if the boundary were brought back to its intended coordinates, it would still be a little over a meter off to the southeast of where it wouldve originally been. That's why survey markers and monuments are so important. They establish a permanent boundary in an environment of imperfect measurement methods and the shifting land itself.
(It makes me wonder whether the main road in Freedom, Wyoming actually straddles the Wyoming-Idaho border as it supposedly does.)
"ARTICLE I. Boundaries
The boundaries of the State of Colorado shall be as follows: Commencing on the thirty-seventh parallel of north latitude, where the twenty-fifth meridian of longitude west from Washington crosses the same; thence north, on said meridian, to the forty-first parallel of north latitude; thence along said parallel, west, to the thirty-second meridian of longitude west from Washington; thence south, on said meridian, to the thirty-seventh parallel of north latitude; thence along said thirty-seventh parallel of north latitude to the place of beginning.
Note the words "WASHINGTON meridian", NOT Greenwich. They are about 3 degrees different. Google on "Washington Meridian" and you'll see the issue.
The statutory position of the corner is at 37 degrees latitude and 25 degrees longitude west of the Washington Meridian. The Washington Meridian was used for a number of state boundaries and was located at approx 77 degrees 03' 2.3" W of Greenwich. The 4 corners monument is fairly close to the statutory position.
The position has never shifted. There is a jog in the west boundary of Colorado but it is to the west not east and has nothing to do with any imaginary error at 4 corners.
There have been several resurveys of the south boundary of Colorado, but all terminate at the same 4 corners monument. That S. boundary of Colorado was adjudicated by the US Supreme Court in 1925 as are all issues relating to state boundaries had no affect on 4 corners.
Boundaries are first determined in an original survey which are considered binding even if they contain some error once they are accepted by proper authority. Authority for State lines are the US congress, the Supreme Court or both States acting together jointly.

Using reed303 and jl-wahl's comments as a starting point, I have drawn the following conclusions and done the math:
The Washington Meridian in 1868 was defined at the center of the small dome at the Old Naval Observatory. At the time they believed that to be 77 2'48"
This would mean the intended border was 32 west of THAT position, giving us 109 2' 48"
The current monument is at 109, 2' 42.62"
Using the GPS Visualizer webpage, and assuming a slight surveying error in latitude, it is revealed that the current monument is a mere 574 FEET from where Congress intended the location to be.
Additionally, the "correct" spot is WEST of the current monument, not east.
Of course, the argument doesn't have to end there, because where they thought the Naval Observatory Dome was in relationship to Greenwich was also off by a bit. But I will leave that to others.
What is the only (are the only) rivers that flow into the state of Colorado?
Answer: The Green and the San Juan (maybe)
My gauge for where the monument is based on the river not flowing into Arizona, otherwise Arizona would have sued for more water rights on the San Juan. I shouldn't give them ideas...
That is an error of .46134' W and .28452' N. At 37 N a longitudal degrees are 68.9581568525283 miles apart, and latitdual degrees are 55.31 miles apart.
This means that the true point is .530219 West, and .411617 miles North of the GPS marker, which pretty much coincides with the established monument.
In short, the monument may not be exactly correct, it's error, however, should be measured in FEET, not miles.
The author of this story should apologize for being to lazy to check his facts. Furthermore as this "story" was picked up by MSNBC, the Deseret News needs to retract it and apologize to the American public, before the misinformation spreads any further.
If you want get to exactly 37N, 109W, then set your GPS for that. You'll end up in a numerically interesting spot that has no borders, intended or accidental. Because it's getting quite clear congress never intended the spot to be exactly on 109W to begin with.
If you want to get to exactly where congress specified the spot should have been, set you GPS for 37N, 109 2' 48" W. (You'll end up no more than roughly 575 feet from the current monument.)
If you want to get to where the borders ACTUALLY meet in reality, then simply go to the current monument. Because that's where they legally meet, in spite of everything the larger media has been claiming all day.
Don't know much topography
But one thing is probably true is that since the border hasn't been disputed for about 110 years it would most likely be ruled by the courts as the true border according to common law border.
I Googled the official boundry of all 4 states. I found multiple sites for 3 of them that placed the boundry at 109 3' W, 37 N. If you consider the boundry to be 109 then the marker is off by 2.5 miles.
So whomever orignally came up with the error did thier math correctly, they just input the wrong border to start with.
As for GPS receiver coordinates, they will always display your location with reference to the Greenwich meridian and it's accuracy is within 2 meters (6.6 feet).
See the Google map street view of 278 W 765 South.
The west side of this lot was extended 15 feet, taking out over half of the backyard of the home at 754 S 300 W.
The new owner of the 765S home tried to shake down the owners on 300W for money to keep their backyard, but they refused and lost their yard, and sold their home at a loss. They also lost thousands hiring a lawyer to defend their 'homesteaded boundries' to no avail. Century 21 who sold them the home didn't even help out.
Bad blood prevailed from a supposed member of the same church and a university employee. Opportunity knocked, and he chose greed.
Secondly, County Surveyors do not have the authority to say if the State corner is correct or not, that lies with the individual State Governments and the Federal Government.
Thirdly, no matter who you are, you should not put so much reliance in any online map software/database i.e. Google Earth, or Google Maps (GIS: Graphic Information Systems), to make calculations or determinations as to True Locations. This data (while usually accurate for geocaching) has been, for the most part, compiled by computer programmers and database managers, NOT Land Surveyors.
Finally, I noticed a comment about GPS receivers being accurate to 2 Meters (6.6 Feet). Unless you have a Survey Grade GPS(sub-centimeter accuracy), your position may be off even more than that. I have seen some Hand held GPS devices that say accurate to 10 Meters (30 feet more or less) Hand held GPS are what are referred to as Mapping Grade just like Google Maps.
