Prairie Creek (California)
Prairie Creek is the Redwood Creek tributary drainage basin including the inland portion of Prairie Creek Redwoods State Park. Prairie Creek drains southerly through a Plio-Pleistocene non-marine sedimentary and metasedimentary formation to a confluence with Redwood Creek approximately one mile upstream of Orick, California. The southern half of the channel exposes the Franciscan Assemblage and the lower reaches flow through Quaternary alluvium of the Redwood Creek estuarine floodplain. Prairie Creek was closely followed by U.S. Route 101 from Orick to the Klamath River drainage divide. The former highway alignment through the park has been designated the Newton B. Drury Scenic Parkway; through traffic now follows a new alignment along the easterly drainage basin headwall.DeLorme ''California Atlas and Gazetteer'' (1st edition) (2008) map 22 References See also *List of rivers in California A ''list'' is any set of items in a row.

Prairie Creek Redwoods State Park
Prairie Creek Redwoods State Park is a state park, located in Humboldt County, California, near the town of Orick and 50 miles (80 km) north of Eureka. The 14,000 acre (57 km²) park is a coastal sanctuary for old-growth Coast Redwood trees. The park is jointly managed by the California Department of Parks and Recreation and the National Park Service as a part of the Redwood National and State Parks. These parks (which includes Del Norte Coast Redwoods State Park, Jedediah Smith Redwoods State Park, and Redwood National Park) have been collectively designated as a World Heritage Site and form part of the California Coast Ranges International Biosphere Reserve. The meadow along the Newton B. Drury Scenic Parkway, with its population of Roosevelt elk, is considered a centerpiece of the park, located near the information center and campground. These open areas of grassland within the redwood forest are locally known as prairies; and the park takes its name from Prair ...

Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Drainage Divide
A drainage divide, water divide, ridgeline, watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges, and may be in the form of a single range of hills or mountains, known as a dividing range. On flat terrain, especially where the ground is marshy, the divide may be difficult to discern. A triple divide is a point, often a summit, where three drainage basins meet. A ''valley floor divide'' is a low drainage divide that runs across a valley, sometimes created by deposition or stream capture. Major divides separating rivers that drain to different seas or oceans are continental divides. The term ''height of land'' is used in Canada and the United States to refer to a drainage divide. It is frequently used in border descriptions, which are set according to the "doctrine of natural boundaries". In glaciated areas it often refers to a low point on a divide where it is ...

Klamath River
The Klamath River (Karuk: ''Ishkêesh'', Klamath: ''Koke'', Yurok: ''Hehlkeek 'We-Roy'') flows through Oregon and northern California in the United States, emptying into the Pacific Ocean. By average discharge, the Klamath is the second largest river in California after the Sacramento River. It drains an extensive watershed of almost that stretches from the arid country of south-central Oregon to the temperate rainforest of the Pacific coast. Unlike most rivers, the Klamath begins in the high desert and flows toward the mountains – carving its way through the rugged Cascade Range and Klamath Mountains before reaching the sea. The upper basin, today used for farming and ranching, once contained vast freshwater marshes that provided habitat for abundant wildlife, including millions of migratory birds. Most of the lower basin remains wild, with much of it designated wilderness. The watershed is known for this peculiar geography, and the Klamath has been called "a river upsid ...

Floodplain
A floodplain or flood plain or bottomlands is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge.Goudie, A. S., 2004, ''Encyclopedia of Geomorphology'', vol. 1. Routledge, New York. The soils usually consist of clays, silts, sands, and gravels deposited during floods. Because the regular flooding of floodplains can deposit nutrients and water, floodplains frequently have high soil fertility; some important agricultural regions, such as the Mississippi river basin and the Nile, rely heavily on the flood plains. Agricultural regions as well as urban areas have developed near or on floodplains to take advantage of the rich soil and fresh water. However, the risk of flooding has led to increasing efforts to control flooding. Formation Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Whereve ...

Estuarine
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, harb ...

Alluvium
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franciscan Assemblage
The Franciscan Complex or Franciscan Assemblage is a geologic term for a late Mesozoic terrane of heterogeneous rocks found throughout the California Coast Ranges, and particularly on the San Francisco Peninsula. It was named by geologist Andrew Lawson, who also named the San Andreas fault that defines the western extent of the assemblage. The Franciscan Complex is dominated by greywacke sandstones, shales and conglomerates which have experienced low-grade metamorphism. Other important lithologies include chert, basalt, limestone, serpentinite, and high-pressure, low-temperature metabasites (blueschists and eclogites) and meta-limestones. Fossils like radiolaria are found in chert beds of the Franciscan Complex. These fossils have been used to provide age constraints on the different terranes that constitute the Franciscan. The mining opportunities within the Franciscan are restricted to deposits of cinnabar and limestone. The outcrops of the formation have a very large range ...

United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Orick, California
Orick (formerly, Arekw, Orekw, and Oreq, Yurok: '' 'O'rekw '') is a census-designated place situated on the banks of the Redwood Creek in Humboldt County, California. It is located north of Eureka, at an elevation of 26 feet (8 m). The population was 357 at the 2010 census. Rare minerals orickite and coyoteite were discovered at Coyote Peak near Orick. History O'rekw means "mouth of the river" in Yurok. Orick evolved from the original word. The Yurok people had 74 known villages in the area, O'rekw was one of five where jumping dances were held. At times spelled Or'eQw, it is important to note that there is no "Q" in the living Yurok people's alphabet. Non-native settlers arrived with the Gold Rush, beginning in 1850 after the Josiah Gregg expedition discovered Humboldt Bay. Orick was settled not only for being on the way to mining claims in the Trinity, but for five beach sand mining claims fronting several miles of beach in the Gold Bluff District. The gold sands did ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
