United States Physiographic Region

The list of continental United States Physiographic regions identifies the 8 regions, 25 provinces, and 85 sections. The system dates to Nevin Fenneman's paper Physiographic Subdivision of the United States, published in 1917. Fenneman expanded and presented his system more fully in two books, Physiography of western United States (1931), and Physiography of eastern United States (1938). In these works Fenneman described 25 provinces and 85 sections of the United States physiography.

Famous quotes containing the words united states, united, states and/or region:

    ... when we shall have our amendment to the Constitution of the United States, everyone will think it was always so, just exactly as many young people believe that all the privileges, all the freedom, all the enjoyments which woman now possesses were always hers. They have no idea of how every single inch of ground that she stands upon to-day has been gained by the hard work of some little handful of women of the past.
    Susan B. Anthony (1820–1906)

    In the United States there’s a Puritan ethic and a mythology of success. He who is successful is good. In Latin countries, in Catholic countries, a successful person is a sinner.
    Umberto Eco (b. 1932)

    Action from principle, the perception and the performance of right, changes things and relations; it is essentially revolutionary, and does not consist wholly with anything which was. It not only divides States and churches, it divides families; ay, it divides the individual, separating the diabolical in him from the divine.
    Henry David Thoreau (1817–1862)

    It was a favor for which to be forever silent to be shown this vision. The earth beneath had become such a flitting thing of lights and shadows as the clouds had been before. It was not merely veiled to me, but it had passed away like the phantom of a shadow, skias onar, and this new platform was gained. As I had climbed above storm and cloud, so by successive days’ journeys I might reach the region of eternal day, beyond the tapering shadow of the earth.
    Henry David Thoreau (1817–1862)
