Coleman City, California
Coleman City, also called Emily City, is a ghost town in San Diego County, California. It lies at an elevation of 3601 feet. It is located on State Highway 79 where it crosses Coleman Creek, about four miles west of Julian. History Coleman City was founded in the early months of 1870 by the first placer miners who rushed to Coleman Creek, following the news of the discovery of gold there by A. E. Coleman who first discovered gold there in January 1870. Coleman, with earlier experience in the gold camps in Northern California, subsequently formed the Coleman Mining District and was its recorder. He also established the Emily City mining town site. This mining camp, later renamed Coleman City in his honor, served the placer gold miners along Coleman Creek in the Coleman Mining District. The San Diego Union reported on February 17, 1870 that the camp had 75 miners inhabiting it. On March 17, following the discovery of the Washington Mine, it reported Coleman City consisted o ...

Ghost Town
A ghost town, deserted city, extinct town, or abandoned city is an abandoned settlement, usually one that contains substantial visible remaining buildings and infrastructure such as roads. A town often becomes a ghost town because the economic activity that supported it (usually industrial or agricultural) has failed or ended for any reason (e.g. a host ore deposit exhausted by mining). The town may have also declined because of natural or human-caused disasters such as floods, prolonged Drought, droughts, extreme heat or extreme cold, government actions, uncontrolled lawlessness, war, pollution, or nuclear and radiation accidents and incidents, nuclear and radiation-related accidents and incidents. The term can sometimes refer to cities, towns, and neighborhoods that, though still populated, are significantly less so than in past years; for example, those affected by high levels of unemployment and dereliction. Some ghost towns, especially those that preserve period-specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coleman Creek (San Diego County)
Coleman Creek is a tributary of the San Diego River in San Diego County, California, that arises at the top of the valley running southeasterly from Julian, at a saddle between two ridges of the Cuyamaca Mountains just south of Kentwood-In-The-Pines. From there, Coleman Creek descends northwesterly down the valley to Julian, where it turns west, descending its canyon northwesterly through the site of Branson City, past the mouth of its tributary Eastwood Creek Eastwood Creek in San Diego County, California, is a tributary of Coleman Creek that arises in the Cuyamaca Mountains The Cuyamaca Mountains (Kumeyaay language, Kumeyaay: ''‘Ekwiiyemak''), locally the Cuyamacas, are a mountain range of the P ... on the north, passing through the south end of Spencer Valley, past the mouth of its tributary Baily Creek on the north, then descending northwest down Quanai Canyon to its confluence with the San Diego River.

Placer Deposit
In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. The name is from the Spanish language, Spanish word ''placer'', meaning "alluvium, alluvial sand". Placer mining is an important source of gold, and was the main technique used in the early years of many gold rushes, including the California Gold Rush. Types of placer deposits include alluvium, eluvium, beach placers, aeolian placers and paleo-placers. Placer materials must be both dense and resistant to weathering processes. To accumulate in placers, mineral particles must have a specific gravity above 2.58. Placer environments typically contain black sand, a conspicuous shiny black mixture of iron oxides, mostly magnetite with variable amounts of ilmenite and hematite. Valuable mineral components often occurring with black sands are monazite, rutile, zircon, chromite, wolframite, and cassiterite. Early mining opera ...

Gold
Gold is a chemical element; it has chemical symbol Au (from Latin ) and atomic number 79. In its pure form, it is a brightness, bright, slightly orange-yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal, a group 11 element, and one of the noble metals. It is one of the least reactivity (chemistry), reactive chemical elements, being the second-lowest in the reactivity series. It is solid under standard temperature and pressure, standard conditions. Gold often occurs in free elemental (native state (metallurgy), native state), as gold nugget, nuggets or grains, in rock (geology), rocks, vein (geology), veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as in electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lode
In geology, a lode is a deposit of metalliferous ore that fills or is embedded in a fracture (or crack) in a rock formation or a vein of ore that is deposited or embedded between layers of rock. The current meaning (ore vein) dates from the 17th century, being an expansion of an earlier sense of a "channel, watercourse" in Late Middle English, which in turn is from the 11th-century meaning of ''lode'' as a "course, way". The generally accepted hydrothermal model of lode deposition posits that metals dissolved in hydrothermal solutions (hot spring fluids) deposit the gold or other metallic minerals inside the fissures in the pre-existing rocks. Lode deposits are distinguished primarily from placer deposits, where the ore has been eroded out from its original depositional environment and redeposited by sedimentation. A third process for ore deposition is as an evaporite. A stringer lode is one in which the rock is so permeated by small veinlets that rather than mining th ...

Former Settlements In San Diego County, California
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being used in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose cone to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until ...

Populated Places Established In 1870
Population is a set of humans or other organisms in a given region or area. Governments conduct a census to quantify the resident population size within a given jurisdiction. The term is also applied to non-human animals, microorganisms, and plants, and has specific uses within such fields as ecology and genetics. Etymology The word ''population'' is derived from the Late Latin ''populatio'' (a people, a multitude), which itself is derived from the Latin word ''populus'' (a people). Use of the term Social sciences In sociology and population geography, population refers to a group of human beings with some predefined feature in common, such as location, race, ethnicity, nationality, or religion. Ecology In ecology, a population is a group of organisms of the same species which inhabit the same geographical area and are capable of interbreeding. The area of a sexual population is the area where interbreeding is possible between any opposite-sex pair within the are ...
