Future article on Unusual Landforms in the United States or "Political borders of the United States"

The features listed her are fairly prominent UNUSUAL features that define the boundaries of states in unusual ways. The features listed should have some sort of article that highlights the unusual feature.

UPDATE - well, this might also spawn an article on boundaries.....

Probably should have a separate articles east and west of the Mississippi River.

Parallels and meridians[edit]

The parallel 41° north forms the northern boundary of the State of Colorado with Nebraska and Wyoming and the southern boundary of the State of Wyoming with Colorado and Utah.

The 41st parallel[1] was also one of the principal baselines used for surveying a portion of lands in Ohio. This marked the southern boundary of the Connecticut Western Reserve and the Firelands using the western boundary with Pennsylvania as the principal meridian. It also served as the baseline for a later survey of Ohio land north of the Greenville Treaty line up to the Fulton line which was the original boundary between Michigan and Ohio under the Northwest Ordinance (see the Toledo Strip). The later survey used the boundary with Indiana as the meridian.

The 42nd parallel north forms most of the New York - Pennsylvania Border, although due to imperfect surveying in 1785-1786, this boundary wanders around on both sides of the true parallel.

The Adams-Onís Treaty of 1819 established the parallel 42° north as the border between the Viceroyality of New Spain of the Kingdom of Spain and the western territory of the United States of America from the meridian of the headwaters of the Arkansas River west to the Pacific Ocean. The Treaty of Guadalupe Hidalgo of 1848 ceded northern Mexico to the United States. As a result, the U.S. states of Oregon and Idaho have the parallel 42° north as their southern border and the U.S. states of California, Nevada, and Utah have the parallel 42° north as their northern border.

The parallel 42° north passes through the southern end of Lake Michigan and Lake Erie. Part of the water boundary between the United States and Canada passes south of the 42nd parallel, and the southern tip of the Canadian province of Ontario just barely goes south of it - this is located at Point Pelee and Pelee Island.


The 37th parallel north forms the southern boundary of the State of Kansas, the State of Colorado, and the State of Utah and the northern boundary of the State of Oklahoma, the State of New Mexico, and the State of Arizona. The intersection of the states of Colorado, New Mexico, Arizona, and Utah at the Four Corners is the only place in the United States where four states touch.

The parallel 37° north formed the southern boundary of the historic and extralegal Territory of Jefferson.

-- In the United States, the 102nd meridian west of Greenwich passes through North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, and Texas. The meridian 102° west of Greenwich formed the eastern border of the historic and extralegal Territory of Jefferson. The eastern border of the Colorado with Nebraska and Kansas lies on the 25th meridian west from Washington, which lies a couple miles west of the 102nd meridian west of Greenwich. 25th meridian west from Washington


The Adams-Onís Treaty settled the dispute by drawing clear borders, roughly granting Florida and Louisiana to the U.S. while giving to Spain everything west of Louisiana from Texas to California. The precise boundary was to be the Sabine River north from the Gulf of Mexico to the 32nd parallel north, then due north to the Red River, west along the Red River to the 100th meridian west, due north to the Arkansas, west to its headwaters, north to the 42nd parallel north, and finally west along the parallel to the Pacific Ocean.
