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.

    ... it is probable that in a fit of generosity the men of the United States would have enfranchised its women en masse; and the government now staggering under the ballots of ignorant, irresponsible men, must have gone down under the additional burden of the votes which would have been thrown upon it, by millions of ignorant, irresponsible women.
    Jane Grey Swisshelm (1815–1884)

    The United States is not a nation to which peace is a necessity.
    Grover Cleveland (1837–1908)

    Courage, then, for the end draws near! A few more years of persistent, faithful work and the women of the United States will be recognized as the legal equals of men.
    Mary A. Livermore (1821–1905)

    Alvina felt herself swept ... into a dusky region where men had dark faces and translucent yellow eyes, where all speech was foreign, and life was not her life. It was as if she had fallen from her own world on to another, darker star, where meanings were all changed.
    —D.H. (David Herbert)
