Clatsop Spit
Clatsop Spit is a giant sand spit on the Pacific coast along U.S. Route 101 between Astoria and the north end of Tillamook Head in Clatsop County, northwest Oregon at the mouth of the Columbia River. The Clatsop Spit was formed by Columbia River sediment brought to the coast by the river flow after the last ice age ended approximately 8500 years ago and the ocean level rose. Here it was worked over and shaped by the wind and the waves until a vast and sandy plain was formed. In regular conversation, referring to Clatsop Spit usually refers to the northern end of the spit: The area that is bound by the Pacific to the west and the Columbia River to the northeast. In the past, the spit was known as ''Clatsop Sands''. Shipwrecks The seas around Clatsop Spit were known to be treacherous and there were many shipwrecks, including the paddle steamer ''General Warren'' in which 42 people died in the surf in 1852 and in 1859, the schooner ''Rambler'' washed up on Clatsop Spit.

Map Clatsop Spit 1905 NOAA
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring to ...

Del Rey Beach Sunset (Clatsop County, Oregon Scenic Images) (clatDA0095)
Del, or nabla, is an operator used in mathematics (particularly in vector calculus) as a vector differential operator, usually represented by the nabla symbol ∇. When applied to a function defined on a one-dimensional domain, it denotes the standard derivative of the function as defined in calculus. When applied to a ''field'' (a function defined on a multi-dimensional domain), it may denote any one of three operators depending on the way it is applied: the gradient or (locally) steepest slope of a scalar field (or sometimes of a vector field, as in the Navier–Stokes equations); the divergence of a vector field; or the curl (rotation) of a vector field. Strictly speaking, del is not a specific operator, but rather a convenient mathematical notation for those three operators that makes many equations easier to write and remember. The del symbol (or nabla) can be interpreted as a vector of partial derivative operators; and its three possible meanings—gradient, divergenc ...

Oregon Coast
The Oregon Coast is a coastal region of the U.S. state of Oregon. It is bordered by the Pacific Ocean to its west and the Oregon Coast Range to the east, and stretches approximately from the California state border in the south to the Columbia River in the north. The region is not a specific geological, environmental, or political entity, and includes the Columbia River Estuary. The Oregon Beach Bill of 1967 allows free beach access to everyone. In return for a pedestrian easement and relief from construction, the bill eliminates property taxes on private beach land and allows its owners to retain certain beach land rights. Traditionally, the Oregon Coast is regarded as three distinct sub–regions: * The North Coast, which stretches from the Columbia River to Cascade Head. * The Central Coast, which stretches from Cascade Head to Reedsport. * The South Coast, which stretches from Reedsport to the Oregon–California border. The largest city is Coos Bay, population 16,700 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warrenton, Oregon
Warrenton is a small, coastal city in Clatsop County, Oregon, United States. Named for D.K. (Daniel Knight) Warren, an early settler, the town is primarily a fishing and logging community. The population was 6,277 according to the 2020 US Census. Warrenton is a less urbanized area close to the Clatsop County seat, Astoria. History Prior to the arrival of the first settlers, this land was inhabited by the Clatsop tribe of Native Americans, whose tribe spanned from the south shore of the Columbia River to Tillamook Head. The county in which Warrenton is located was named after these people, as well as the last encampment that the Lewis and Clark Expedition established. Today, a replica of Fort Clatsop still stands just outside of Warrenton city limits. The first pioneers who settled on the land that would become Warrenton (between 1845 and the early 1850s) were Jeremiah Gerome Tuller, J. W. Wallace, D. E. Pease, Ninian A. Eberman and George Washington Coffenbury. Coffenbury ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gearhart, Oregon
Gearhart is a city in Clatsop County, Oregon, United States. The population was 1,462 at the 2010 census. Geography According to the United States Census Bureau, the city has a total area of , of which is land and is water. History The city is named for Phillip Gearhart, a settler who in 1848 set out from Independence, Missouri, with his family and arrived in Oregon City in October of that year. He rented a log cabin on Clatsop Plains. At that time, other farmers had already settled primarily on the northern Plains. The first farmer to settle there was Solomon Smith. In 1851, Gearhart bought a squatter's right in the south Plains for $1,000. He used it to create a donation land claim; the US patent was granted in 1874. Gearhart increased his holdings by in 1859 through a purchase from Obadiah C. Motley, and again in 1863 by purchased from Jefferson J. Louk. The entire parcel encompassed all of what is now called Gearhart, as well as a portion of Seaside across the N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lewis And Clark National Historical Park
The Lewis and Clark National Historical Park (including the former Fort Clatsop National Memorial), located in the vicinity of the mouth of the Columbia River, commemorates the Lewis and Clark Expedition. Administration of the park, which includes both federal and state lands, is a cooperative effort of the National Park Service and the states of Oregon and Washington. The National Historical Park was dedicated on November 12, 2004. After reaching the Pacific Ocean, the Corps of Discovery camped at Fort Clatsop in the winter of 1805–1806.

Fort Stevens (Oregon)
Fort Stevens was an American military installation that guarded the mouth of the Columbia River in the state of Oregon. Built near the end of the American Civil War, it was named for a slain Civil War general and former Washington Territory governor, Isaac I. Stevens. The fort was an active military reservation from 1863–1947. It is now listed on the National Register of Historic Places. Today the site is an Oregon state park just northwest of Warrenton. History Civil War The fort was constructed in 1863-64 during the Civil War as an earthwork battery on the south shore of the mouth of the Columbia River, and was known as the Fort at Point Adams. It was later renamed as Fort Stevens in 1865, in honor of the former territorial governor of Washington, Isaac Stevens, who had been killed in action at the Battle of Chantilly during the American Civil War.

Fort Clatsop
Fort Clatsop was the encampment of the Lewis and Clark Expedition in the Oregon Country near the mouth of the Columbia River during the winter of 1805–1806. Located along the Lewis and Clark River at the north end of the Clatsop Plains approximately southwest of Astoria, the fort was the last encampment of the Corps of Discovery, before embarking on their return trip east to St. Louis. The Lewis and Clark Expedition wintered at Fort Clatsop before returning east to St. Louis in the spring of 1806. It took just over 3 weeks for the Expedition to build the fort, and it served as their camp from December 8, 1805 until their departure on March 23, 1806. The site is now protected as part of the Lewis and Clark National Historical Park, part of which was formerly known as Fort Clatsop National Memorial until 2004. The original Fort Clatsop decayed in the wet climate of the region but was reconstructed for the sesquicentennial in 1955 from sketches in the journals of William Clark. ...

Clatsop Plains
The Clatsop Plains are an area of wetlands and sand dunes between the Northern Oregon Coast Range and Pacific Ocean in northwestern Oregon in the United States. They stretch from near the mouth of the Columbia River south to the vicinity of Tillamook Head near Seaside. The plains are drained by several coastal rivers include the Skipanon River and the Necanicum River, which flow parallel to the coast and empty into the Columbia at Youngs Bay near Astoria and into the Pacific Ocean near Seaside respectively. At the time, the Lewis and Clark Expedition recorded a different river draining the plains which entered the Pacific near the current day Camp Rilea Armed Forces Training Center. Research, 200 years later in 2005, seems to have confirmed this by locating an old river channel. The plains are named for the Clatsop tribe of Native Americans who lived in the area at the time of the arrival of Europeans and European Americans by ship at the end of the 18th century and by land ...

Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented sa ...

List Of Dams In The Columbia River Watershed
There are more than 60 dams in the Columbia River watershed in the United States and Canada. Tributaries of the Columbia River and their dammed tributaries, as well as the main stem itself, each have their own list below. The dams are listed in the order as they are found from source to terminus. Many of the dams in the Columbia River watershed were not created for the specific purposes of water storage or flood protection. Instead, the primary purpose of many of these dams is to produce hydroelectricity. As can be seen in the lists, these dams provide many tens of gigawatts of power. Major dam construction began in the early 20th century and picked up the pace after the Columbia River Treaty in the 1960s, by the mid 1980s all the big dams were finished. Including just the dams listed below, there are 60 dams in the watershed, with 14 on the Columbia, 20 on the Snake, seven on the Kootenay, seven on the Pend Oreille / Clark, two on the Flathead, eight on the Yakima, and t ...
