Washington (/ˈwɒʃɪŋtən/ (About this soundlisten)), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington, the first U.S. president, the state was made out of the western part of the Washington Territory, which was ceded by the British Empire in 1846, in accordance with the Oregon Treaty in the settlement of the Oregon boundary dispute. The state, which is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north, was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle. Washington is often referred to as Washington state to distinguish it from the nation's capital, Washington, D.C.

Washington is the 18th largest state, with an area of 71,362 square miles (184,827 km2), and the 13th most populous state, with more than 7.7 million people. Approximately 60 percent of Washington's residents live in the Seattle metropolitan area, the center of transportation, business, and industry along Puget Sound, an inlet of the Pacific Ocean consisting of numerous islands, deep fjords, and bays carved out by glaciers. The remainder of the state consists of deep temperate rainforests in the west; mountain ranges in the west, central, northeast, and far southeast; and a semi-arid basin region in the east, central, and south, given over to intensive agriculture. Washington is the second most populous state on the West Coast and in the Western United States, after California. Mount Rainier, an active stratovolcano, is the state's highest elevation, at almost 14,411 feet (4,392 meters), and is the most topographically prominent mountain in the contiguous U.S.

Washington is a leading lumber producer; its rugged surface is rich in stands of Douglas fir, hemlock, ponderosa pine, white pine, spruce, larch, and cedar. Washington is the nation's largest producer of apples, hops, pears, red raspberries, spearmint oil, and sweet cherries, and ranks high in the production of apricots, asparagus, dry edible peas, grapes, lentils, peppermint oil, and potatoes. Livestock and livestock products make important contributions to total farm revenue, and the commercial fishing of salmon, halibut, and bottomfish makes a significant contribution to the state's economy. Washington ranks second only to California in wine production.

Manufacturing industries in Washington include aircraft and missiles, shipbuilding, and other transportation equipment, food processing, metals and metal products, chemicals, and machinery. Washington has more than a thousand dams, including the Grand Coulee Dam, built for a variety of purposes including irrigation, power, flood control, and water storage.

Washington is one of the wealthiest and most socially liberal states in the country.[4] The state consistently ranks among the best for life expectancy and low unemployment.[5] Along with Colorado, Washington was one of the first to legalize medicinal and recreational cannabis, was among the first thirty-six states to legalize same-sex marriage, doing so in 2012, and was one of only four U.S. states to have been providing legal abortions on request before the 1973 Supreme Court decision in Roe v. Wade loosened abortion laws nationwide. Similarly, Washington voters approved a 2008 referendum on legalization of physician-assisted suicide, and is currently one of nine states, along with the District of Columbia to have legalized the practice.

Etymology

Washington was named after President George Washington by an act of the United States Congress during the creation of Washington Territory in 1853. The territory was to be named "Columbia", for the Columbia River and the Columbia District, but Kentucky representative Richard H. Stanton found the name too similar to the District of Columbia (the national capital, itself containing the city of Washington), and proposed naming the new territory after President Washington.[6][7][8] Washington is the only U.S. state named after a president.[9]

Confusion over the state of Washington and the city of Washington, D.C., led to renaming proposals during the statehood process for Washington in 1889, including David Dudley Field II's suggestion to name the new state "Tacoma". These proposals failed to garner support.[10] Washington, D.C.'s, own statehood movement in the 21st century includes a proposal to use the name "State of Washington, Douglass Commonwealth", which would conflict with the current state of Washington.[11] Residents of Washington (known as "Washingtonians") and the Pacific Northwest simply refer to the state as "Washington",[citation needed] and the nation's capital "Washington, D.C.", "the other Washington",[12] or simply "D.C."

Washington is the northwesternmost state of the contiguous United States. It borders Idaho to the east, bounded mostly by the meridian running north from the confluence of the Snake River and Clearwater River (about 117°02'23" west), except for the southernmost section where the border follows the Snake River. Oregon is to the south, with the Columbia River forming the western part and the 46th parallel forming the eastern part of the Oregon-Washington border. During Washington's partition from Oregon, the original plan for the border followed the Columbia River east until the confluence with the Snake, and then would have followed the Snake River east; this was changed in order to keep Walla Walla's fertile farmland in Washington.

To the west of Washington lies the Pacific Ocean.[13] 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.[14]

Washington is part of a region known as the Pacific Northwest, a term which always refers to at least Washington and Oregon, and may or may not include some or all the following, depending on the user's intent: Idaho, western Montana, northern California, British Columbia, and Alaska.

The high mountains of the Cascade Range run north–south, bisecting the state. In addition to Western Washington and Eastern Washington, residents call the two parts of the state the "West side" and the "East side", "Wet side" and "Dry side", or "Timberland" and "Wheatland", the latter pair more commonly in the names of region-specific businesses and institutions. These terms reflect the geography, climate and industry of the land on both sides of the Cascades.

Washington (state) (Washington (state))

From the Cascade Mountains westward, Western Washington has a mostly Mediterranean Climate, with mild temperatures and wet winters, autumns and springs, and relatively dry summers. The Cascade Range has several volcanoes, which reach altitudes significantly higher than the rest of the mountains. From north to south, these major volcanoes are Mount Baker, Glacier Peak, Mount Rainier, Mount St. Helens, and Mount Adams. All are active volcanoes. Mount Rainier, the tallest mountain in the state,[15] is 50 miles (80 km) south of the city of Seattle, from which it is prominently visible. The USGS considers 14,411-foot-tall (4,392 m) Mount Rainier the most dangerous volcano in the Cascade Range, due to its proximity to the Seattle metropolitan area, and most dangerous in the continental U.S. according to the Decade Volcanoes list.[16] It is also covered with more glacial ice than any other peak in the contiguous 48 states.[17]

Western Washington also is home of the Olympic Mountains, far west on the Olympic Peninsula, which support dense forests of conifers and areas of temperate rainforest. These deep forests, such as the Hoh Rainforest, are among the only rainforests in the continental United States.[18] Indeed, while Western Washington does not always suffer from a high amount of rainfall as measured in total inches of rain per year, it does consistently have more rainy days per year than most other places in the country.[19]

Eastern Washington

Southeastern Washington

Eastern Washington—the part of the state east of the Cascades—has a relatively dry climate, in distinct contrast to the west side. It includes large areas of semiarid steppe and a few truly arid deserts in the rain shadow of the Cascades; the Hanford reservation receives an average annual precipitation of 6 to 7 inches (150 to 180 mm). Despite the limited amount of rainfall, agriculture is an extremely important business throughout much of Eastern Washington, as the soil is highly productive and irrigation, aided by dams along the Columbia River, is fairly widespread. The spread of population in Eastern Washington is dominated by access to water, especially rivers. The main cities are all located alongside rivers or lakes; indeed, most of them are named after the river or lake they adjoin.

Farther east, the climate becomes less arid, with annual rainfall increasing as one goes east to 21.2 inches (540 mm) in Pullman, near the Washington-Idaho border.[20] The Okanogan Highlands and the rugged Kettle River Range and Selkirk Mountains cover much of the state's northeastern quadrant. The Palouse southeast region of Washington was grassland that has been mostly converted into farmland, and extends to the Blue Mountains.[21]

As described above, Washington's climate varies greatly from west to east. A Mediterranean climate predominates in western Washington, and a much drier semi-arid climate prevails east of the Cascade Range. Major factors determining Washington's climate include the large semi-permanent high pressure and low pressure systems of the north Pacific Ocean, the continental air masses of North America, and the Olympic and Cascade mountains. In the spring and summer, a high pressure anticyclone system dominates the north Pacific Ocean, causing air to spiral out in a clockwise fashion. For Washington, this means prevailing winds from the northwest bring relatively cool air and a predictably dry season.

In the autumn and winter, a low-pressure cyclone system takes over in the north Pacific Ocean. The air spiraling inward in a counter-clockwise fashion causes Washington's prevailing winds to come from the southwest, and bring relatively warm and moist air masses and a predictably wet season. The term "Pineapple Express" is used colloquially to describe atmospheric river events, where repeated storm systems are directed by this persistent cyclone from tropical and near-tropical Pacific regions into the Pacific Northwest.[23]

Despite western Washington's having a marine climate similar to many coastal cities of Europe, there are exceptions such as the "Big Snow" events of 1880, 1881, 1893, and 1916, and the "deep freeze" winters of 1883–1884, 1915–1916, 1949–1950, and 1955–1956, among others. During these events, western Washington experienced up to 6 feet (1.8 m) of snow, sub-zero (−18 °C) temperatures, three months with snow on the ground, and lakes and rivers frozen over for weeks.[24] Seattle's lowest officially recorded temperature is 0 °F (−18 °C) set on January 31, 1950, but low-altitude areas approximately three hours away from Seattle have recorded lows as cold as −48 °F (−44 °C).[25]

The Southern Oscillation greatly influences weather during the cold season. During the El Niño phase, the jet stream enters the U.S. farther south through California, therefore late fall and winter are drier than normal with less snowpack. The La Niña phase reinforces the jet stream through the Pacific Northwest, causing Washington to have more rain and snow than average.

In 2006, the Climate Impacts Group at the University of Washington published The Impacts of Climate change in Washington's Economy, a preliminary assessment on the risks and opportunities presented given the possibility of a rise in global temperatures and their effects on Washington state.[26]

Rain shadow effects

Main article: Rain shadow

Washington experiences extensive variation in rainfall.

Rainfall in Washington varies dramatically going from east to west. The Olympic Peninsula's western side receives as much as 160 inches (4,100 mm) of precipitation annually, making it the wettest area of the 48 conterminous states and a temperate rainforest. Weeks may pass without a clear day. The western slopes of the Cascade Range receive some of the heaviest annual snowfall (in some places more than 200 inches or 5,100 millimeters water equivalent) in the country. In the rain shadow area east of the Cascades, the annual precipitation is only 6 inches (150 mm). Precipitation then increases again eastward toward the Rocky Mountains (about 120 miles east of the Idaho border).

The Olympic mountains and Cascades compound this climatic pattern by causing orographic lift of the air masses blown inland from the Pacific Ocean, resulting in the windward side of the mountains receiving high levels of precipitation and the leeward side receiving low levels. This occurs most dramatically around the Olympic Mountains and the Cascade Range. In both cases the windward slopes facing southwest receive high precipitation and mild, cool temperatures. While the Puget Sound lowlands are known for clouds and rain in the winter, the western slopes of the Cascades receive larger amounts of precipitation, often falling as snow at higher elevations. Mount Baker, near the state's northern border, is one of the snowiest places in the world. In 1999, it set the world record for snowfall in a single season—1,140 inches (95 ft; 29 m).[27]

East of the Cascades, a large region experiences strong rain shadow effects. Semi-arid conditions occur in much of eastern Washington with the strongest rain shadow effects at the relatively low elevations of the central Columbia Plateau—especially the region just east of the Columbia River from about the Snake River to the Okanagan Highland. Thus, instead of rain forests, much of eastern Washington is covered with dry grassland, shrub-steppe, and sand dunes.

Temperatures

The average annual temperature ranges from 51 °F (11 °C) on the Pacific coast to 40 °F (4 °C) in the northeast. The lowest temperature recorded in the state was −48 °F (−44 °C) in Winthrop and Mazama. The highest recorded temperature in the state was 118
