Washington

Washington was named after George Washington, the first President of the United States, and is the only U.S. state named after a president. Washington is commonly called Washington State or occasionally the state of Washington to distinguish it from the District of Columbia. However, Washingtonians (and many residents of neighboring states) normally refer to the state simply as "Washington" while usually referring to the nation's capital as "Washington, D.C." or simply "D.C." Washingtonians from the District of Columbia often refer to the state as the other Washington.

Washington is the northwestern-most state of the contiguous United States. Its northern border lies mostly along the 49th parallel, and then via marine boundaries through the Strait of Georgia, Haro Strait and Strait of Juan de Fuca, with the Canadian province of British Columbia to the north. Washington borders Oregon to the south, with the Columbia River forming most of the boundary and the 46th parallel forming the eastern part of the southern boundary. To the east Washington borders Idaho, bounded mostly by the meridian running north from the confluence of the Snake River and Clearwater River (about 116°57' west), except for the southernmost section where the border follows the Snake River. To the west of Washington lies the Pacific Ocean. Washington was a Union territory during the American Civil War, although it never actually participated in the war.

The high mountains of the Cascade Range run north-south, bisecting the state. Western Washington, west of the Cascades, has a mostly marine west coast climate with relatively mild temperatures, wet winters, and dry summers. Western Washington also supports dense forests of conifers and areas of temperate rain forest. In contrast, Eastern Washington, east of the Cascades, has a relatively dry climate with large areas of semiarid steppe and a few truly arid deserts lying in the rainshadow of the Cascades; the Hanford reservation receives an average annual precipitation of between six and seven inches (178 mm). Farther east, the climate becomes less arid. The Palouse region of southeast Washington was grassland that has been mostly converted into farmland. Other parts of eastern Washington are forested and mountainous.

Washington's position on the Pacific Ocean and the harbors of Puget Sound give the state a leading role in maritime trade with Alaska, Canada, and the Pacific Rim. Puget Sound's many islands are served by the largest ferry fleet in the United States.
