Quad Cities - Geography

Geography

The Quad Cities are located at the confluence of the Rock and Mississippi rivers, approximately 180 miles (290 km) west of Chicago, and is the largest metropolitan area along the Mississippi River between Minneapolis–Saint Paul and the St. Louis metropolitan area. Interstate 80 crosses the Mississippi River here. The Quad Cities area is distinctive because the Mississippi River flows from east to west as it passes through the heart of the area; the Iowa cities of Davenport and Bettendorf are located due north of Rock Island and Moline, respectively.

The Quad Cities area is one where the telephone companies cooperate with regional phone calls. Iowa and Illinois have different area codes (563 and 309 respectively), yet most calls originating and terminating within the core urban area are placed without long-distance charges by dialing just a 7-digit number. This helps the bi-state area promote itself as a single community, "joined by a river."

The Quad Cities Metropolitan Area consists of four counties: Scott County in Iowa and Henry, Mercer, and Rock Island counties in Illinois. The Quad City metro population is 381,342. The Quad Cities Metropolitan Area is also considered part of the Great Lakes Megalopolis.

    At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.
    Derek Wall (b. 1965)

    The California fever is not likely to take us off.... There is neither romance nor glory in digging for gold after the manner of the pictures in the geography of diamond washing in Brazil.
    Rutherford Birchard Hayes (1822–1893)

    Yet America is a poem in our eyes; its ample geography dazzles the imagination, and it will not wait long for metres.
