United States Geological Survey

The United States Geological Survey (USGS) is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.

A bureau of the U.S. Department of the Interior, it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California.

The motto of the USGS is "Science for a changing world".

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

    I hate to do what everybody else is doing. Why, only last week, on Fifth Avenue and some cross streets, I noticed that every feminine citizen of these United States wore an artificial posy on her coat or gown. I came home and ripped off every one of the really lovely refrigerator blossoms that were sewn on my own bodices.
    Carolyn Wells (1862–1942)

    In the United States the whites speak well of the Blacks but think bad about them, whereas the Blacks talk bad and think bad about the whites. Whites fear Blacks, because they have a bad conscience, and Blacks hate whites because they need not have a bad conscience.
    Friedrich Dürrenmatt (1921–1990)

    Sean Thornton: I don’t get this. Why do we have to have you along. Back in the states I’d drive up, honk the horn, a gal’d come runnin’ out.
    Mary Kate Danaher: Come a runnin’. I’m no woman to be honked at and come a runnin’.
    Frank S. Nugent (1908–1965)

    The crystal sphere of thought is as concentrical as the geological structure of the globe. As our soils and rocks lie in strata, concentric strata, so do all men’s thinkings run laterally, never vertically.
    Ralph Waldo Emerson (1803–1882)

    By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.
    Owen Barfield (b. 1898)
