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 white American man makes the white American woman maybe not superfluous but just a little kind of decoration. Not really important to turning around the wheels of the state. Well the black American woman has never been able to feel that way. No black American man at any time in our history in the United States has been able to feel that he didn’t need that black woman right against him, shoulder to shoulder—in that cotton field, on the auction block, in the ghetto, wherever.”
—Maya Angelou (b. 1928)
“Yesterday, December 7, 1941Ma date that will live in infamy—the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan.”
—Franklin D. Roosevelt (1882–1945)
“I do not know that the United States can save civilization but at least by our example we can make people think and give them the opportunity of saving themselves. The trouble is that the people of Germany, Italy and Japan are not given the privilege of thinking.”
—Franklin D. Roosevelt (1882–1945)
“In a moment when criticism shows a singular dearth of direction every man has to be a law unto himself in matters of theatre, writing, and painting. While the American Mercury and the new Ford continue to spread a thin varnish of Ritz over the whole United States there is a certain virtue in being unfashionable.”
—John Dos Passos (1896–1970)
“And hereby hangs a moral highly applicable to our own trustee-ridden universities, if to nothing else. If we really wanted liberty of speech and thought, we could probably get it—Spain fifty years ago certainly had a longer tradition of despotism than has the United States—but do we want it? In these years we will see.”
—John Dos Passos (1896–1970)
