In the United States, a state is a constituent political entity, of which there are currently 50. Bound together in a political union, each state holds governmental jurisdiction over a separate and defined geographic territory and shares its sovereignty with the federal government. Due to this shared sovereignty, Americans are citizens both of the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons restricted by certain types of court orders. Four states use the term commonwealth rather than state in their full official names.
Oregon is a state in the Pacific Northwest region on the West Coast of the United States. The Columbia River delineates much of Oregon's northern boundary with Washington, while the Snake River delineates much of its eastern boundary with Idaho. The parallel 42° north delineates the southern boundary with California and Nevada. Oregon is one of only three states of the contiguous United States to have a coastline on the Pacific Ocean.
Yamhill County is a county in the U.S. state of Oregon. As of the 2010 census, the population was 99,193. The county seat is McMinnville. The name's origin is probably an explorer's name for a local Native American tribe, the Yamhill, who are part of the North Kalapuyan family.
The Columbia River is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the US state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is 1,243 miles (2,000 km) long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven US states and a Canadian province. The fourth-largest river in the United States by volume, the Columbia has the greatest flow of any North American river entering the Pacific.
The Oregon Trail is a 2,170-mile (3,490 km) historic East–West, large-wheeled wagon route and emigrant trail in the United States that connected the Missouri River to valleys in Oregon. The eastern part of the Oregon Trail spanned part of the future state of Kansas, and nearly all of what are now the states of Nebraska and Wyoming. The western half of the trail spanned most of the future states of Idaho and Oregon.
The Willamette River is a major tributary of the Columbia River, accounting for 12 to 15 percent of the Columbia's flow. The Willamette's main stem is 187 miles (301 km) long, lying entirely in northwestern Oregon in the United States. Flowing northward between the Oregon Coast Range and the Cascade Range, the river and its tributaries form the Willamette Valley, a basin that contains two-thirds of Oregon's population, including the state capital, Salem, and the state's largest city, Portland, which surrounds the Willamette's mouth at the Columbia.
Multnomah County is one of 36 counties in the U.S. state of Oregon. As of the 2010 United States Census, the county's population was 735,334. Its county seat, Portland, is the state's largest city. Multnomah County is part of the Portland-Vancouver-Hillsboro, OR-WA Metropolitan Statistical Area, and though smallest in area, it is the state's most populous county.
The Columbia River Gorge is a canyon of the Columbia River in the Pacific Northwest of the United States. Up to 4,000 feet (1,200 m) deep, the canyon stretches for over 80 miles (130 km) as the river winds westward through the Cascade Range forming the boundary between the State of Washington to the north and Oregon to the south. Extending roughly from the confluence of the Columbia with the Deschutes River in the east down to the eastern reaches of the Portland metropolitan area, the water gap furnishes the only navigable route through the Cascades and the only water connection between the Columbia River Plateau and the Pacific Ocean. It is thus the route of Washington State Route 14, Interstate 84, U.S. Route 30, and railroad tracks on both sides.
Eastern Oregon is the eastern part of the U.S. state of Oregon. It is not an officially recognized geographic entity; thus, the boundaries of the region vary according to context. It is sometimes understood to include only the eight easternmost counties in the state; in other contexts, it includes the entire area east of the Cascade Range. Cities in the basic 8-county definition include Baker City, Burns, Hermiston, Pendleton, John Day, La Grande, and Ontario. Umatilla County is home to the largest population base in Eastern Oregon; accounting for 74% of the region's population in 2016. Hermiston, located in Umatilla County, is the largest city in the region. Major industries include transportation/warehousing, timber, agriculture, and tourism. The main transportation corridors are I-84, U.S. Route 395, U.S. Route 97, U.S. Route 26, U.S. Route 30, and U.S. Route 20.
The Applegate Trail was an emigrant trail through the present-day U.S. states of Idaho, Nevada, California, and Oregon used in the mid-19th century by emigrants on the American frontier. It was originally intended as a less dangerous alternative to the Oregon Trail by which to reach the Oregon Territory. Much of the route was coterminous with the California Trail.
Prospect State Scenic Viewpoint, is a state park south of the community of Prospect on Oregon Route 62 in Jackson County, in the U.S. state of Oregon. It was formerly known as Mill Creek Falls Scenic Area, a private hiking area that was developed by Willamette Industries along the Rogue River. Both Mill Creek Falls and Pearsony Falls are contained within the area, with Barr Creek Falls close by.
The Barlow Road is a historic road in what is now the U.S. state of Oregon. It was built in 1846 by Sam Barlow and Philip Foster, with authorization of the Provisional Legislature of Oregon, and served as the last overland segment of the Oregon Trail. Its construction allowed covered wagons to cross the Cascade Range and reach the Willamette Valley, which had previously been nearly impossible. Even so, it was by far the most harrowing 100 miles (160 km) of the nearly 2,000-mile (3,200 km) Oregon Trail.
Central Oregon is a geographic region in the U.S. state of Oregon and is traditionally considered to be made up of Deschutes, Jefferson, and Crook counties. Other definitions include larger areas, often encompassing areas to the north towards the Columbia River, eastward towards Burns, or south towards Klamath Falls. These three counties have a combined population of 153,558 as of the 2000 census, with Deschutes the largest of the three counties, having approximately four times the population of the other two counties combined. As of 2015, the most populous city in the region is Bend, with an estimated 87,014 residents. As defined by the three county definition, Central Oregon covers 7,833 square miles (20,290 km2) of land. Central Oregon has had 3 record tourism years beginning in 2012. Over 2.2 million people visited Central Oregon in 2012 and again in 2013.
The Klamath Basin is the region in the U.S. states of Oregon and California drained by the Klamath River. It contains most of Klamath County and parts of Lake and Jackson counties in Oregon, and parts of Del Norte, Humboldt, Modoc, Siskiyou, and Trinity counties in California. The 15,751-square-mile (40,790 km2) drainage basin is 35% in Oregon and 65% in California. In Oregon, the watershed typically lies east of the Cascade Range, while California contains most of the river's segment that passes through the mountains. In the Oregon-far northern California segment of the river, the watershed is semi-desert at lower elevations and dry alpine in the upper elevations. In the western part of the basin, in California, however, the climate is more of temperate rainforest, and the Trinity River watershed consists of a more typical alpine climate.

The Oregon Coast Range, often called simply the Coast Range and sometimes the Pacific Coast Range, is a mountain range, in the Pacific Coast Ranges physiographic region, in the U.S. state of Oregon along the Pacific Ocean. This north-south running range extends over 200 miles (320 km) from the Columbia River in the north on the border of Oregon and Washington, south to the middle fork of the Coquille River. It is 30 to 60 miles wide and averages around 1,500 feet (460 m) in elevation above sea level. The coast range has three main sections, a Northern, Central, and Southern.
The Oregon Steam Navigation Company (O.S.N.) was an American company incorporated in 1860 in Washington with partners J. S. Ruckle, Henry Olmstead, and J. O. Van Bergen. It was incorporated in Washington because of a lack of corporate laws in Oregon, though it paid Oregon taxes.
