Before Present
Before Present (BP) years, or "years before present", is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date (epoch) of the age scale. The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must now account for. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation RCYBP stands for the explicit "radio carbon years before present". Usage The BP scale is sometimes used for dates established by means other than radiocarbon dating, such as stratigraphy. This usage differs from t ...

California Southern Railroad
The California Southern Railroad was a subsidiary railroad of the Atchison, Topeka and Santa Fe Railway (Santa Fe) in Southern California. It was organized July 10, 1880, and chartered on October 23, 1880, to build a rail connection between what has become the city of Barstow and San Diego, California. Construction began in National City, just south of San Diego, in 1881, and proceeded northward to the present day city of Oceanside. From there, the line turned to the northeast through Temecula Canyon, then on to the present cities of Lake Elsinore, Perris and Riverside before a connection to the Southern Pacific Railroad (SP) in Colton. Following a frog war where the SP refused to let the California Southern cross its tracks, a dispute that was resolved by court order in favor of the California Southern, construction continued northward through Cajon Pass to the present day cities of Victorville and Barstow. The line, completed on November 9, 1885, formed the western ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Grant
A land grant is a gift of real estate—land or its use privileges—made by a government or other authority as an incentive, means of enabling works, or as a reward for services to an individual, especially in return for military service. Grants of land are also awarded to individuals and companies as incentives to develop unused land in relatively unpopulated countries; the process of awarding land grants are not limited to the countries named below. The United States historically gave out numerous land grants as Homesteads to individuals desiring to prove a farm. The American Industrial Revolution was guided by many supportive acts of legislatures (for example, the Main Line of Public Works legislation of 1826) promoting commerce or transportation infrastructure development by private companies, such as the Cumberland Road turnpike, the Lehigh Canal, the Schuylkill Canal and the many railroads that tied the young United States together. Ancient Rome Roman soldiers were given pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chione Cancellata
''Chione cancellata'', is a species of medium-sized saltwater clam, a marine bivalve mollusc in the family Veneridae, the venus clams. The species is now understood to be strictly Caribbean in distribution. The more northern species which resembles this, which is usually called the "cross-barred venus" and which was considered to be ''C. cancellata'' for many years, is now known to be '' Chione elevata''. Shell description This species grows to be 1 inches across, and has a rounded, triangular shell with both strong concentric ridges and strong radial ribbing, which together form a raised crisscross pattern of ridges, hence the specific name, ''cancellata'' or cancellate. The interior of the shell possesses crenulations on its bottom edge, and like most Veneridae it has well-developed lateral and cardinal teeth on the hinge line. The shell of ''C. cancellata'' ''sensu stricto'' is quite brightly colored and patterned. (This is in contrast to the species '' C. elevata'' whi ...

Scallop
Scallop () is a common name that encompasses various species of marine bivalve mollusks in the taxonomic family Pectinidae, the scallops. However, the common name "scallop" is also sometimes applied to species in other closely related families within the superfamily Pectinoidea, which also includes the thorny oysters. Scallops are a cosmopolitan family of bivalves found in all of the world's oceans, although never in fresh water. They are one of the very few groups of bivalves to be primarily "free-living", with many species capable of rapidly swimming short distances and even migrating some distance across the ocean floor. A small minority of scallop species live cemented to rocky substrates as adults, while others attach themselves to stationary or rooted objects such as seagrass at some point in their lives by means of a filament they secrete called a byssal thread. The majority of species, however, live recumbent on sandy substrates, and when they sense the presence of a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kumeyaay
The Kumeyaay, also known as Tipai-Ipai or by their historical Spanish name Diegueño, is a tribe of Indigenous peoples of the Americas who live at the northern border of Baja California in Mexico and the southern border of California in the United States. Their Kumeyaay language belongs to the Yuman–Cochimí language family. The Kumeyaay consist of three related groups, the Ipai, Tipai and Kamia. The San Diego River loosely divided the Ipai and the Tipai historical homelands, while the Kamia lived in the eastern desert areas. The Ipai lived to the north, from Escondido to Lake Henshaw, while the Tipai lived to the south, in lands including the Laguna Mountains, Ensenada, and Tecate. The Kamia lived to the east in an area that included Mexicali and bordered the Salton Sea. Name The Kumeyaay or Tipai-Ipai were formerly known as the Kamia or Diegueños, the former Spanish name applied to the Mission Indians living along the San Diego River. They are referred to as the Kumiai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Los Peñasquitos Canyon Preserve
Los Peñasquitos Canyon Preserve is an urban park in San Diego, California. Stretching approximately , the park encompasses some of both Peñasquitos and Lopez canyons, and is one of the largest urban parks in the United States. The preserve is jointly owned and administered by the City of San Diego and the County of San Diego.

Mud Flat
Mudflats or mud flats, also known as tidal flats or, in Ireland, slob or slobs, are coastal wetlands that form in intertidal areas where sediments have been deposited by tides or rivers. A global analysis published in 2019 suggested that tidal flat ecosystems are as extensive globally as mangroves, covering at least of the Earth's surface. / They are found in sheltered areas such as bays, bayous, lagoons, and estuaries; they are also seen in freshwater lakes and salty lakes (or inland seas) alike, wherein many rivers and creeks end. Mudflats may be viewed geologically as exposed layers of bay mud, resulting from deposition of estuarine silts, clays and aquatic animal detritus. Most of the sediment within a mudflat is within the intertidal zone, and thus the flat is submerged and exposed approximately twice daily. A recent global remote sensing analysis estimated that approximately 50% of the global extent of tidal flats occurs within eight countries (Indonesia, China, Austral ...
