Oregon

Oregon is a state located in the Pacific Northwest region of the western United States.

The Pacific Ocean forms its entire western boundary. To the north, the Columbia River serves as a border with Washington. The Snake River marks much of the eastern border with Idaho. The southern boundary is defined by the 42° north parallel, which separates Oregon from California and Nevada.

The geography of Oregon is exceptionally diverse. The landscape includes massive volcanoes and dense evergreen or mixed forests. Other areas consist of high deserts and semi-arid shrublands. Mount Hood is the highest point in the state.

The state also contains Crater Lake National Park. This park features a caldera that holds Crater Lake, the deepest lake in the United States.

Interestingly, the Malheur National Forest is home to Armillaria ostoyae. This fungus is the single largest organism in the world.

Human history in the region began thousands of years ago with indigenous nations.

Evidence of habitation at Fort Rock Cave and Paisley Caves dates back at least 13,200 to 15,000 years. By 8000 BC, settlements existed throughout the state. Many groups lived there, including the Chinook, Nez Perce, and Umatilla. During the last glacial period, massive floods from Lake Missoula flooded the Willamette Valley. These floods filled the valley with 400 feet of water.

European exploration began in the 16th century. Spanish explorers led by Juan Rodríguez Cabrillo sighted the coast in 1543. In 1579, Sir Francis Drake anchored at South Cove near Coos Bay. Later, the Lewis and Clark Expedition traversed northern Oregon in the early 19th century. They stayed at Fort Clatsop from December 1805 to March 1806.

The first permanent European settlement was Fort Astoria, established in 1811 by John Jacob Astor's Pacific Fur Company.

Political control of the region changed several times. The Treaty of 1818 allowed for joint occupation by the United Kingdom and the United States. The Hudson's Bay Company dominated much of the area from its headquarters at Fort Vancouver.

Eventually, the Oregon Treaty of 1846 brought the region under American sovereignty. This led to the creation of the Oregon Territory two years later. Oregon was officially admitted as the 33rd U.S. state on February 14, 1859.

Today, Oregon has a population of approximately 4.2 million people. It is the ninth-largest state by land area and the 27th-most populous.

Portland is the largest city, with 652,503 residents. The Portland metropolitan area is the 26th largest in the nation, with 2,512,859 people. Salem is the state capital and has 175,535 residents.

The state's population is also characterized by various ethnic origins.

The economy of Oregon has evolved through several stages. Historically, it relied on agriculture, fishing, logging, and hydroelectric power. Oregon is currently the top lumber producer in the contiguous United States.

In the 1970s, technology became a major force through the "Silicon Forest." This growth was driven by companies like Intel and Tektronix. The sportswear company Nike, Inc. is headquartered in Beaverton.

Nike is the state's largest public corporation, with an annual revenue of $46.7 billion.

The origin of the name "Oregon" remains a subject of debate. One theory suggests it comes from the Spanish word "orejón," meaning "one with big ears." Another theory links it to the French word for "windstorm," referring to Chinook winds. Some suggest it comes from the Portuguese word "Ouve a água," meaning "hear the waters."

Others believe it resulted from an engraver's error on an 18th-century French map. Regardless of its origin, the name is a central part of the state's identity.
