Ash Creek (Polk County, Oregon)
Ash Creek is a short stream in Polk County, in the U.S. state of Oregon. Formed by the merger of its north and middle forks near Monmouth, it flows generally east to meet the Willamette River at Independence. The creek passes under Oregon Route 51 just before entering the river. The creek's mouth is about upstream of the Willamette's confluence with the Columbia River. The map includes mile markers along the Willamette. North Fork Ash Creek begins at the eastern edge of the Central Oregon Coast Range near Dallas at and flows generally southeast to meet the Middle Fork. Middle Fork Ash Creek begins at near Mount Pisgah and flows generally east. Both forks pass under Oregon Route 99W shortly before they merge to form the main stem. Ash Creek is joined by a third fork, South Fork Ash Creek, in Independence. The South Fork begins at slightly south of the Middle Fork and flows generally east to meet the main stem at The South Fork passes under Route 99W south of Monmouth and u ...

Independence, Oregon
Independence is a city in Polk County, Oregon, United States, on the west bank of the Willamette River along Oregon Route 51, and east of nearby Monmouth. It is part of the Salem Metropolitan Statistical Area. Thirty square blocks of the oldest part of Independence form the National Register of Historic Places-listed Independence Historic District. The population was 9,828 at the 2020 census. History Independence was founded by pioneers who migrated from Independence, Missouri. Elvin A. Thorp arrived in the Independence area in 1845 and staked a claim north of Ash Creek in June of that year. He platted a small townsite that later became known as "Thorp's Town of Independence" or the "Original Town of Independence", now known as "Old Town". Thorp named the town for his eponymous hometown in Missouri, as well as in honor of Andrew Jackson's characteristic of "Independence". In 1847, Henry Hill came across the plains looking for a level piece of ground on which to raise stock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dallas is along Rickreall Creek, about west of Salem, at an elevation of above sea level. It is part of the Salem Metropolitan Statistical Area. History Pioneers in the 1840s started the settlement that became known as Dallas on the north side of Rickreall Creek. It was originally named "Cynthian" or "Cynthiana". A 1947 ''Itemizer-Observer'' article states: " e town was called Cynthiana after Cynthiana, Ky., so named by Mrs. Thos. Lovelady." According to the county historical society in 1987, Mrs. Thomas J. Lovelady named the new settlement after her home town of Cynthiana, Kentucky. Another source claims that Cynthia Ann, wife of early pioneer Jesse Applegate, named the settlement. But they lived in the Salt Creek area of northern Polk County and, according to the 1850 Federal Census, she was not living in Polk County then. Dallas post office was estab ...

Tributaries Of The Willamette River
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & Scott ...

Riparian Zone
A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grasslands, woodlands, wetlands, or even non-vegetative areas. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin '' ripa'', meaning " river bank". Characteristics Riparian zones may be natural or engineered for soil stabilization or restoration. These zones are important natural b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Settler
A settler is a person who has human migration, migrated to an area and established a permanent residence there, often to colonize the area. A settler who migrates to an area previously uninhabited or sparsely inhabited may be described as a pioneer. Settlers are generally from a Sedentism, sedentary culture, as opposed to nomads, nomadic peoples who may move settlements seasonally, within traditional territories. Settlement sometimes relies on dispossession of already established populations within the contested area, and can be a very violent process. Sometimes settlers are backed by governments or large countries. Settlements can prevent native people from continuing their work. Historical usage One can witness how settlers very often occupied land previously residents to long-established peoples, designated as Indigenous peoples, Indigenous (also called "natives", "Aborigines" or, in the Americas, "Indians"). The process by which Indigenous territories are settled by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Stem
In hydrology, a mainstem (or trunk) is "the primary downstream segment of a river, as contrasted to its tributaries". Water enters the mainstem from the river's drainage basin, the land area through which the mainstem and its tributaries flow.. A drainage basin may also be referred to as a ''watershed'' or ''catchment''. Hydrological classification systems assign numbers to tributaries and mainstems within a drainage basin. In the Strahler number, a modification of a system devised by Robert E. Horton in 1945, channels with no tributaries are called "first-order" streams. When two first-order streams meet, they are said to form a second-order stream; when two second-order streams meet, they form a third-order stream, and so on. In the Horton system, the entire mainstem of a drainage basin was assigned the highest number in that basin. However, in the Strahler system, adopted in 1957, only that part of the mainstem below the tributary of the next highest rank gets the highest num ...

Oregon Route 99W
Oregon Route 99W is a state-numbered route in Oregon, United States, that runs from OR 99 and OR 99E in Junction City north to I-5 in southwestern Portland. Some signage continues it north to US 26 near downtown, but most signage agrees with the Oregon Department of Transportation's (ODOT) description, ending it at I-5. OR 99W is known by ODOT as the Pacific Highway West No. 1W (see Oregon highways and routes); that highway continues north through downtown (along a former extension of OR 99W) to the Pacific Highway No. 1 (I-5) in northern Portland, as well as south on OR 99 to the Pacific Highway (I-5) in Eugene. Until around 1972, OR 99W was U.S. Route 99W, rejoining OR 99E (formerly US 99E) in northern Portland. US 99 then continued north along present I-5 into Washington; the next segment still numbered 99 is WA 99 south of Seattle. Route description The Pacific Highway West begins at the interchange with I-5 (Pacific Highway) and OR 126 Business ( McKenzie Highway ...

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Oregon Coast Range
The Central Oregon Coast Range is the middle section of the Oregon Coast Range, in the Pacific Coast Ranges physiographic region, and located in the west-central portion of the state of Oregon, United States roughly between the Salmon River and the Umpqua River and the Willamette Valley and the Pacific Ocean. This approximately long mountain range contains mountains as high as 4,097 feet (1,226 m) for Marys Peak. Portions of the range are inside the Siuslaw National Forest and three wilderness areas exist as well: Drift Creek Wilderness, Cummins Creek Wilderness and Rock Creek Wilderness. Geology The underlying rock of the Central Coast Range are the igneous rocks from the Siletz River Volcanics of the Paleocene age. It is estimated that this rock formation is up to thick. These formations consist mainly of pillow basalt, large lava flows, tuff-breccia, and sills. This part of the mountains are approximately 50 to 60 million years old. It is theorized that the source of these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polk County, Oregon
Polk County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 87,433. The county seat is Dallas. The county is named for James Knox Polk, the 11th president of the United States. Polk County is part of the Salem, OR Metropolitan Statistical Area, which is also included in the Portland-Vancouver-Salem, OR- WA Combined Statistical Area. It is located in the Willamette Valley. History The Oregon Provisional Legislature created Polk County from Yamhill District on December 22, 1845, granting to it the entire southwestern portion of present-day Oregon to the California border. County boundaries were periodically changed to reflect the creation of Benton and Lincoln counties. Many other counties were subsequently carved out of these as settlement spread towards the south, leaving Polk County many counties away from its former border with California. The first county seat was a settlement on the north side of Rickreall Creek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbia River
The Columbia River (Upper Chinook: ' or '; Sahaptin: ''Nch’i-Wàna'' or ''Nchi wana''; Sinixt dialect'' '') 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 U.S. 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 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 Columbia has the 36th greatest discharge of any river in the world. The Columbia and its tributaries have been central to the region's culture and economy for thousands of years. They have been used for transportation since a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
