100th Meridian West - United States

United States

In the United States the meridian 100° west of Greenwich forms the eastern border of the Texas panhandle with Oklahoma (which traces its origin to the Adams-Onís Treaty in 1819 which settled the border between New Spain and the United States between the Red River and Arkansas River). Dodge City, Kansas lies exactly at the intersection of the Arkansas River and the 100th meridian.

In the central Great Plains, the meridian roughly marks the western boundary of the normal reach of moist air from the Gulf of Mexico, and the approximate boundary (although some areas do push the boundary slightly farther east) between the semi-arid climate to the west and the humid continental (north of about 37°N) and humid subtropical (south of about 37°N) climates to the east. The type of agriculture west of the meridian typically relies heavily on irrigation. Historically the meridian has often been taken as a rough boundary between the eastern and western United States. White settlement, spreading westward after the American Civil War, encroached in the meridian in the 1870s.

A sign across U.S. Highway 30 in Cozad, Nebraska prominently marks the place where the meridian intersects the routes of the Oregon Trail, Pony Express, transcontinental railroad, and the Lincoln Highway.

Famous quotes related to united states:

    The United States is just now the oldest country in the world, there always is an oldest country and she is it, it is she who is the mother of the twentieth century civilization. She began to feel herself as it just after the Civil War. And so it is a country the right age to have been born in and the wrong age to live in.
    Gertrude Stein (1874–1946)

    In the United States there is more space where nobody is is than where anybody is.
    Gertrude Stein (1874–1946)

    Hollywood ... was the place where the United States perpetrated itself as a universal dream and put the dream into mass production.
    Angela Carter (1940–1992)

    In the United States, though power corrupts, the expectation of power paralyzes.
    John Kenneth Galbraith (b. 1908)

    It was evident that, both on account of the feudal system and the aristocratic government, a private man was not worth so much in Canada as in the United States; and, if your wealth in any measure consists in manliness, in originality and independence, you had better stay here. How could a peaceable, freethinking man live neighbor to the Forty-ninth Regiment? A New-Englander would naturally be a bad citizen, probably a rebel, there,—certainly if he were already a rebel at home.
    Henry David Thoreau (1817–1862)
