Notes
[edit]- ^ The Constitution of the Provisional Government of the Territory of Jefferson[88] states its boundaries as "Commencing at a point where the 37th degree of north latitude, crosses the 102nd degree of west longitude, and running north on said meridian to the 43d degree of north latitude; thence west on said parallel to the 110th degree of west longitude; thence south on said meridian to the 37th degree of north latitude; thence east on the said parallel to the place of beginning."
- ^ The Constitution of the State of Deseret[94] states its boundaries as "commencing at the 33 degree of north latitude where it crosses the 108 degree of longitude west of Greenwich thence running south and west to and down the main channel of the Gila River on the northern line of Mexico and on the northern boundary of Lower California to the Pacific Ocean thence along the coast north westerly to 118 degrees 30 minutes of west longitude thence north to where said line intersects the dividing ridge of the Sierra Nevada mountains thence north along the summit of the Sierra Nevada mountains to the dividing range of mountains that separates the waters flowing into the Columbia River from the waters running into the Great Basin thence easterly along the dividing range of mountains that separates said waters flowing into the Columbia River on the north from the waters flowing into the Great Basin on the south to the summit of the Wind River chain of mountains thence south east and south by the dividing range of mountains that separate the waters flowing into the Gulf of Mexico from the waters flowing into the Gulf of California to the place of beginning as set forth in a map drawn by Charles Preuss and published by order of the Senate of the United States in 1848." This ambitious claim included the future cities of Las Vegas, Phoenix, San Diego, and Los Angeles.
- ^ a b The Republic of Texas claimed as its eastern and northern border the Adams–Onís border[d] with the United States and as its western and southern border the Rio Grande to its headwaters, thence north along meridian 107°32′35″ west to the Adams–Onís border with the United States. The western extent of this claim was dubious since the Republic of Texas never occupied any territory west of the 102nd meridian west. This claim included half of the Mexican province of Santa Fe de Nuevo México, established centuries before in 1598.
- ^ a b c d e In Colorado, the border set by the Adams–Onís Treaty between the United States and the Spanish Empire extended up the Arkansas River to its headwaters, thence north along the meridian 106°20'35" west. The United States surrendered the area in the future state south and west of the Arkansas River and east of both the Continental Divide and the Sangre de Cristo Divide. North of the headwaters of the Arkansas River, the border was moved from the Continental Divide to the meridian 106°20'35" west. The Adams–Onís border was affirmed by the Treaty of Limits between the United States and the United Mexican States.
- ^ At its greatest territorial extent, the Spanish Empire claimed that the border of its colony of New Mexico (Santa Fe de Nuevo México) began where the 31st parallel north crossed 100th meridian west, thence north along the 100th meridian west to the 42nd parallel north, thence west along the 42nd parallel north to the Green River (río Español), thence down the Green River to its confluence with the Colorado River (río Colorado), thence down the Colorado River to its confluence with the Gila River (río Gila), thence up the Gila River up to its confluence with its East Fork and West Fork, thence south along the meridian 108°12′22″ west to the 31st parallel north, thence east along the 31st parallel north back to the 100th meridian west.
