10) USA

1) At present, UNESCO official list of world heritage sites has no examples of industrial heritage in the United States (http://whc.unesco.org/en/statesparties/us). In the tentative list (http://whc.unesco.org/en/tentativelists/state=us) we find "only" a selection (http://whc.unesco.org/en/tentativelists/5249/) of eleven architectonical projects of Frank Lloyd Wright (1867-1959), of which the most important cultural public space is the Guggenheim Museum. In the presentation of India, we observed an important study about possibilities of industrial heritage sites; the author presents a list (http://whc.unesco.org/archive/ind-study01.pdf), in which we choose:

a) the Brooklyn Bridge, New York;

b) the Eads Bridge, Illinois - St. Louis, Missouri;

c) we add here the Golden Gate, San Francisco, as monuments of buildig bridges;

d) the General Electric Research Laboratory, Schenectady, New York (http://www.ge.com/company/history/research.html), the first laboratory for industrial research in the USA and classed in the U.S. National Register of historical places (http://en.wikipedia.org/wiki/General_Electric_Research_Laboratory), for which we organize visits;

e) the original Bell Telephone Laboratories, New York;

f) the George Westinghouse Museum in Wilmerding, Pittsburgh (http://en.wikipedia.org/wiki/George_Westinghouse), about the history of one of the most important american railway engineer, and creator of an electrotechnical factory which had an important part to develop electrical railway traction.

Each state of the Union has own museums; here, about history of public transport, we propose the National Museum of American History, Washington D.C. (http://americanhistory.si.edu/collections/index.cfm), in particular for its collections of transport vehicles. If you like flying, you have to visit the National Air and Space Museum, also in Washington (http://en.wikipedia.org/wiki/National_Air_and_Space_Museum). As example of private collection, we indicate the Henry Ford Museum at Dearbon, Michigan (http://en.wikipedia.org/wiki/The_Henry_Ford), because it is an important collection of engines and means of transport of American industrial revolution.

We wish to visit two monuments of the art of dam building: 

- the Hoover Dam, or Boulder Dam (http://en.wikipedia.org/wiki/Hoover_Dam) in the Black Canyon of the Colorado River near Boulder City, Nevada. It is the largest dam of the type concrete arch-gravity ever built, started in 1931 (during the Great Depression) and completed in 1936; a symbol of the New Deal, in an impressive natural scenery;

- the Grand Coulee Dam (http://en.wikipedia.org/wiki/Grand_Coulee_Dam) on the Columbia River, Grant and Okanogan counties (State of Washington). It is an enormous gravity dam, constructed between 1933 and 1942; President Franklin Delano Roosevelt called it "the high dam" (168 meters!), and the artificial lake was baptized with his name. The natural scenery is not so spectacular as in the Black Canyon, but the Visitor Center is very important not only for historical and technological aspects, but also for documentation about social impact and consequences due to this imposant work.

You remember surely the romantic stern wheel steamboats (with a back - single large paddlewheel) on the Mississippi river; a river steamboat has been preserved in Chattanooga, Tennesse (http://en.wikipedia.org/wiki/Delta_Queen) as museum ship. She has operated since 2009 as static hotel (http://www.deltaqueenhotel.net/), but with plans to return in service. 

The region of the Great Lakes of North America between eight States and Canada (http://en.wikipedia.org/wiki/Great_Lakes) offers a singular attraction, "Boatwatching". We refer to the Great Lakes Steamboats fleet; an important number of historical cargos is still in service (although rebuilt with diesel engines), near many museum ships. But at least two ships own original engine: cargo St. Marys Challenger 
(http://www.boatnerd.com/pictures/fleet/stmaryschallenger.htm)  and steam ferry Badger (http://www.ssbadger.com/home.aspx). This true monument of traditional steam technology (1953) is the last preserved operative passenger steamer on Lake Michigan, on the route Ludington - Manitowoc (temporary out of service because of important maintenance works).

2) The United States   is an industrial power, with production in the

chemical and manufacturing industry leaders in their respective
sectors. The United States is the third largest petroleum producer in
the world, as well as the largest importer of this commodity. It is a
leader in the production of electricity and nuclear, as well as for
the extraction of natural gas, sulfur, phosphates, and salt
in New York's manufacturing industry occupies a significant proportion
of the population, but its role is declining. The main areas are
chemistry, metallurgy, clothing, food and furniture.
An important economic role is also played by the cultur industry:are
located in new york television and movie studios, and numeros media
groups.

The fields "creative" such as design, architectural studies, fashion
as those related to high technology and medical research, especially,
are another area of rapid growth. Also important is tourism.

3) The US tourism industry determines to a large extent the economy of United States of America.
The effect of the US tourism industry on the economy of USA indicates the place of importance, the tourism industry holds in America.
The Travel and tourism satellite accounting is an efficient tool or instrument to get a feed back about the status of the economic setup owing to the travel and tourism related activities.
Travel and tourism industry in USA has several other industries closely associated with it.

Contribution of these associated industries have a tremendous impact on the US tourism industry.
