History
The United States acquired the four corners region from Mexico after the end of the
Mexican–American War
The Mexican–American War, also known in the United States as the Mexican War and in Mexico as the (''United States intervention in Mexico''), was an armed conflict between the United States and Mexico from 1846 to 1848. It followed the 1 ...
in 1848. In 1863 Congress created the
Arizona Territory from the western part of
New Mexico Territory
The Territory of New Mexico was an organized incorporated territory of the United States from September 9, 1850, until January 6, 1912. It was created from the U.S. provisional government of New Mexico, as a result of ''Santa Fe de Nuevo México ...
. The boundary was legally defined as a line running due south from the southwest corner of
Colorado Territory
The Territory of Colorado was an organized incorporated territory of the United States that existed from February 28, 1861, until August 1, 1876, when it was admitted to the Union as the State of Colorado.
The territory was organized in the ...
, which had been created in 1861. This was an unusual act of Congress, which almost always defined the boundaries of new territories as lines of latitude or longitude, or following rivers, but seldom as extensions of other boundaries.
By defining one boundary as starting at the corner of another, Congress ensured the eventual creation of four states meeting at a point, regardless of the inevitable errors of boundary surveying. Due to a "standard" survey error of the time, the originally surveyed location of the "Four Corners" point was unintentionally located by its initial surveyor as being east of the original location actually specified by the US Congress in 1863. The area was first surveyed by the U.S. Government in 1868 as part of an effort to make Colorado Territory into a state, the first of the Four Corners states formed.
The first marker was placed at the originally surveyed and current spot in 1868.
[ In 1925, some 57 years after Congress had first attempted to specify the spot, the problems surrounding the originally misplaced marker were brought up before the US Supreme Court. In order to amicably remedy this original surveying error, the US Supreme Court then redefined the point of the Four Corners, officially moving the Four Corners point roughly east, to where the original survey had first held it to be all along, and to where it remains to this day, duly marked.][ Correction of mistaken federal survey.
] This initial survey error has resulted in some longstanding misunderstandings about the correct location of the Four Corners marker, some of which remain to this day. The first Navajo tribal government was established in 1923 to regulate an increasing number of oil exploration activities on Navajo land.[
