Cañada Gobernadora
Cañada Gobernadora is a tributary to San Juan Creek, about long, in southern Orange County in the U.S. state of California. The creek begins in the foothills of the Santa Ana Mountains (), at an elevation of , and flows south through residential, agricultural and finally undeveloped land, to its confluence with San Juan Creek a few miles upstream of the city of San Juan Capistrano (). The upper half of the stream is largely channelized and flows through golf courses, while the lower half is a wash-like channel that can be up to wide. The stream receives some urban runoff from the residential communities higher in its watershed. The watershed includes several geologic formations, including the Tertiary Sespe Formation and Santiago Formation, and Holocene sedimentary and alluvial deposits embedded in its narrow floodplain. Cañada Gobernadora forms an unofficial dividing line for the lower portion of the San Juan watershed; most urban development is confined to west of the creek's ...

Sespe Formation
The Sespe Formation is a widespread fossiliferous sedimentary geologic unit in southern and south central California in the United States. It is of nonmarine origin, consisting predominantly of sandstones and conglomerates laid down in a riverine, shoreline, and floodplain environment between the upper Eocene Epoch (around 40 million years ago) through the lower Miocene. It is often distinctive in appearance, with its sandstones weathering to reddish-brown, maroon, pinkish-gray, tan, and green. Since many of its sandstones are more resistant to erosion than many other regional sedimentary units it often forms dramatic outcrops and ridgelines in many local mountain ranges. Type locality The type locality of the Sespe is along Sespe Creek in the Topatopa Mountains, about four miles (6 km) north of Fillmore, where it was first named in 1897 and redefined in 1924. Subdivision The Sespe Formation has been divided into three clearly differentiable subunits, designed Lower, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mission San Juan Capistrano
Mission San Juan Capistrano ( es, Misión San Juan Capistrano) is a Spanish mission in San Juan Capistrano, Orange County, California. Founded November 1, 1776 in colonial ''Las Californias'' by Spanish Catholic missionaries of the Franciscan Order, it was named for Saint John of Capistrano. The Spanish Colonial Baroque style church was located in the Alta California province of the Viceroyalty of New Spain. The Mission was founded less than 60 yards from the village of Acjacheme. The Mission was secularized by the Mexican government in 1833, and returned to the Roman Catholic Church by the United States government in 1865. The Mission was damaged over the years by a number of natural disasters, but restoration and renovation efforts date from around 1910. It functions today as a museum. Introduction The mission was founded in 1776, by the Spanish Catholics of the Franciscan Order. Named for Saint John of Capistrano, a 14th-century theologian and "warrior priest" who resided ...

Piwiva
Piwiva was a Acjachemen village located at the meeting place of the San Juan Creek and Cañada Gobernadora tributary in what is now Rancho Mission Viejo, California. The name for the village was closely related to the Payómkawichum word for wild tobacco ''piivat''. It was located north of Mission San Juan Capistrano, downstream from the village of Huumai and upstream from the village of Sajavit. Alternative names for the village include Pii'iv, Pivits, and Peviva. History The village was visited by the Portolá expedition in January 1770, after being missed on the first pass through the area in July 1769. Juan Crespí described the encounter as follows: "We met with no villages here on the way going up, but now we came upon some small houses roofed with tule rushes, with a good many gentile men, women and children living encamped here in the hollow. No sooner did they see us than, as if pleased, they set up a great hubbub, and all came over weaponless to the camp, very well p ...

Acjachemen
The Acjachemen (, alternate spelling: Acagchemem) are an Indigenous people of California. They historically lived south of what is known as Aliso Creek and north of the Las Pulgas Canyon in what are now the southern areas of Orange County and the northwestern areas of San Diego County. The Spanish colonizers called the Acjachemen ''Juaneños'', following their baptism at Mission San Juan Capistrano in the late 18th century. Today many contemporary members of the tribe prefer the term ''Acjachemen'' as their autonym, or name for themselves. The name is derived from the village of Acjacheme, which was less than sixty yards from the site where Mission San Juan Capistrano was built in 1776. Their language was a variety closely related to the Luiseño language of the nearby Payómkawichum (Luiseño) people. In the 20th century, the Juaneño Band of Mission Indians, Acjachemen Nation was organized but is not federally recognized. The lack of federal recognition has prevented the A ...

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 ...

Alluvial
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] |
Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied. In the early d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tributary
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 & S ...
