Washington, officially the State of Washington, is a state in the Pacific Northwest region of the United States. It is often referred to as Washington state or Washington State to distinguish it from the national capital, both named for George Washington (the first U.S. president). Washington borders the Pacific Ocean to the west, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. The state was formed from the western part of the Washington Territory, which was ceded by the British Empire in the Oregon Treaty of 1846. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital, and the most populous city is Seattle.

Washington is the 18th-largest state, with an area of 71,362 square miles (184,830 km2), and the 13th-most populous state, with more than 7.8 million people. The majority of Washington's residents live in the Seattle metropolitan area, the center of transportation, business, and industry on 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, center, northeast, and far southeast; and a semi-arid basin region in the east, center, 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 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. The state is the largest producer of apples, hops, pears, blueberries, spearmint oil, and sweet cherries in the U.S., and ranks high in the production of apricots, asparagus, dry edible peas, grapes, lentils, peppermint oil, and potatoes. Livestock, livestock products, and commercial fishing—particularly of salmon, halibut, and bottomfish—are also significant contributors to the state's economy. Washington ranks second only to California in wine production. (Full article...)

On March 27, 1980, a series of volcanic explosions and pyroclastic flows began at Mount St. Helens in Skamania County, Washington, United States. A series of phreatic blasts occurred from the summit and escalated until a major explosive eruption took place on May 18, 1980, at 8:32 am. The eruption, which had a volcanic explosivity index of 5, was the first to occur in the contiguous United States since the much smaller 1915 eruption of Lassen Peak in California. It has often been declared the most disastrous volcanic eruption in U.S. history.

The eruption was preceded by a two-month series of earthquakes and steam-venting episodes caused by an injection of magma at shallow depth below the volcano that created a large bulge and a fracture system on the mountain's north slope. An earthquake at 8:32:11 am PDT (UTC−7) on May 18, 1980, caused the entire weakened north face to slide away, a sector collapse which was the largest subaerial landslide in recorded history. This allowed the partly molten rock, rich in high-pressure gas and steam, to suddenly explode northward toward Spirit Lake in a hot mix of lava and pulverized older rock, overtaking the landslide. An eruption column rose 80,000 feet (24 km; 15 mi) into the atmosphere and deposited ash in 11 U.S. states and various Canadian provinces. At the same time, snow, ice, and several entire glaciers on the volcano melted, forming a series of large lahars (volcanic mudslides) that reached as far as the Columbia River, nearly 50 miles (80 km) to the southwest. Less severe outbursts continued into the next day, only to be followed by other large, but not as destructive, eruptions later that year. The thermal energy released during the eruption was equal to 26 megatons of TNT. (Full article...)

Olympia is the capital of the U.S. state of Washington and the county seat and most populous city of Thurston County.

The Squaxin and other Coast Salish peoples inhabited the southern Puget Sound region prior to the arrival of European and American settlers in the 19th century. The Treaty of Medicine Creek was signed in 1854 and followed by the Treaty of Olympia in 1856; these two treaties forced the Squaxin to relocate to an Indian reservation. Olympia was incorporated as a town on January 28, 1859, and as a city in 1882. It had a population of 55,605 at the time of the 2020 census, making it the state of Washington's 23rd most populous city. Olympia borders Lacey to the east and Tumwater to the south.
