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).

In the central Great Plains, the meridian roughly marks the western boundary of the normal reach of moist air from the Gulf of Mexico. 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.

Wallace Stegner's Beyond the Hundredth Meridian (1954), is a biography of John Wesley Powell, an explorer of the American West. The song "At the Hundredth Meridian" by The Tragically Hip is about the 100th meridian west, specifically in Canada, and how it has traditionally been considered "where the great plains begin."
