The Trans Alaska Pipeline System (TAPS), includes the Trans Alaska Pipeline, 11 pump stations, several hundred miles of feeder pipelines, and the Valdez Marine Terminal. TAPS is one of the world's largest pipeline systems. It is commonly called the Alaska Pipeline, Trans Alaska Pipeline, or Alyeska Pipeline, (or the Pipeline as referred to in Alaska), but those terms technically apply only to the 800 miles (1,287 km) of the pipeline with the diameter of 48 inches (122 cm) that conveys oil from Prudhoe Bay, to Valdez, Alaska. The crude oil pipeline is privately owned by the Alyeska Pipeline Service Company.
The pipeline was built between 1974 and 1977 after the 1973 oil crisis caused a sharp rise in oil prices in the United States. This rise made exploration of the Prudhoe Bay oil field economically feasible. Environmental, legal, and political debates followed the discovery of oil at Prudhoe Bay in 1968, and the pipeline was built only after the oil crisis provoked the passage of legislation designed to remove legal challenges to the project.
Alaska (i/əˈlæskə/) is the largest state in the United States by area. It is situated in the northwest extremity of the North American continent, with Canada to the east, the Arctic Ocean to the north, and the Pacific Ocean to the west and south, with Russia further west across the Bering Strait. Alaska is the 4th least populous and the least densely populated of the 50 United States. Approximately half of Alaska's 722,718 residents live within the Anchorage metropolitan area.
Alaska was purchased from Russia on March 30, 1867, for $7.2 million ($120 million in today's[when?] dollars) at approximately two cents per acre ($4.74/km²). The land went through several administrative changes before becoming an organized (or incorporated) territory on May 11, 1912, and the 49th state of the U.S. on January 3, 1959.
The name "Alaska" (Аляска) was already introduced in the Russian colonial period, when it was used only for the peninsula and is derived from the Aleut alaxsxaq, meaning "the mainland" or, more literally, "the object towards which the action of the sea is directed". It is also known as Alyeska, the "great land", an Aleut word derived from the same root.
