Willamette River
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 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. Originally created by plate tectonics about 35 million years ago and subsequently altered by volcanism and erosion, the river's drainage basin was significantly modified by the Missoula Floods at the end of the most recent ice age. Humans began living in the watershed over 10,000 years ago. There were once many tribal villages along the lower river and in the area around its mouth on the Columbia. Indigenous peoples lived throughout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oak Grove, Oregon
Oak Grove is an unincorporated community in Clackamas County, Oregon, United States, in the Portland metropolitan area. For statistical purposes, the United States Census Bureau has defined Oak Grove as a census-designated place (CDP). The census definition of the area may not precisely correspond to local understanding of the area with the same name. The population was 16,629 at the 2010 census.

The company that was developing the property had not been able to come up with a good name for the place, and Cornell suggested "Oak Grove" after a crew ate lunch in a stand of oak trees in the northwestern part of the tract. The area was served first from the Milwaukie post office. In 1904, Creighton post office was established, named for Susan Creighton, on whose donation land claim the office stood.

Census-designated Place
A census-designated place (CDP) is a concentration of population defined by the United States Census Bureau for statistical purposes only. CDPs have been used in each decennial census since 1980 as the counterparts of incorporated places, such as self-governing cities, towns, and villages, for the purposes of gathering and correlating statistical data. CDPs are populated areas that generally include one officially designated but currently unincorporated community, for which the CDP is named, plus surrounding inhabited countryside of varying dimensions and, occasionally, other, smaller unincorporated communities as well. CDPs include small rural communities, edge cities, colonias located along the Mexico–United States border, and unincorporated resort and retirement communities and their environs. The boundaries of any CDP may change from decade to decade, and the Census Bureau may de-establish a CDP after a period of study, then re-establish it some decades later. Most unin ...
