National Geodetic Survey officials say the Four Corners marker showing the intersection of Arizona, Colorado, New Mexico and Utah is about 2.5 miles (4 kilometers) west of where it should be, the Deseret News reported.
The only place in the United States where four state boundaries come together was first surveyed by the government in 1868 during the initial survey of Colorado’s southern boundary. The survey was inaccurate.
When we collect data, do experiement and examine the natural world, our observations are only as good as the equipment available to us. Historic geographic surveys were especially prone to error, since their equipment often lacked the precision that is now possible today.
I (thought) I visited the 4 corners several years ago on a school trip. I guess we were several miles off the mark!
