Readings show Four Corners marker off by 2.5 miles

The Associated Press

Tourists who want to put a hand or foot in each of four states at the Four Corners area are apparently off the mark by about 2.5 miles.

According to readings by the National Geodetic Survey, the Four Corners marker showing the intersection of Arizona, Colorado, New Mexico and Utah is about 2.5 miles west of where it should be.

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.

The intended location was 109 degrees west longitude and 37 degrees north latitude. But, because of surveying errors, the popular tourist spot is a bit off.

The accurate 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.

I had heard that it was only off about 300ft or so.

Darn Surveyors, cant' do anything right. :)
I'm a Surveyor by the way.

Its amazing how things change with technology.
Those guys were using transits and chains and literally walking their way across the country. They did make many mistakes due to the limitations of their equipment but is amazing how many things they got dead on also.
Today with GPS everything is so much easier and faster and we can get 2cm.
It is amazing to be out in the field and find monuments these guys set 120 years ago and to prove they are in the right location.

That sounds like a very cool thing to do. I love history.

True, but a surveyor would never certify to that. CYA. :)

Yep. Everything moves. It is just a mm at some point in time (all puns intended).:D
