Arivaca Schoolhouse
The Arivaca Schoolhouse is a historic one-room school building located in the unincorporated community of Arivaca, in southern Pima County, Arizona. A small and simple structure made of locally manufactured mud adobe bricks, the Arivaca Schoolhouse was built in 1879 and is the oldest standing schoolhouse remaining in Arizona. It was added to the National Register of Historic Places on April 16, 2012, and is now used as a center for community activities. The Arivaca Schoolhouse was built by Don Pedro Aguirre, an Arizona pioneer that had come to the United States from his native Chihuahua, Mexico, in the 1850s. The school was run by School District No. 2, Pima County. In 1868, Aguirre opened a stagecoach stop for his freighting business near Arivaca and eventually became one of the leading citizens of the community during its period of development in the 1870s. In 1879, Aquirre built the Arivaca Schoolhouse for his own children and those of his employees, at his own expense. The buil ...

Cerro Colorado, Arizona
Cerro Colorado is a ghost town in southern Pima County, Arizona. The town is located off Arivaca Road, near Arivaca, and is best known for the massacre of mining employees by Mexican outlaws and buried treasure. History Cerro Colorado was established around 1855 by Charles D. Poston, who owned the Sonora Exploring & Mining Company in Tubac, Arizona. The most prosperous mine in the area was the Heintzelman Mine, named after Major General Samuel P. Heintzelman, who was the first president of the mining company and later grew famous during the American Civil War. The post office was established on April 17, 1879, and closed on April 15, 1911. In 1861, fifteen Mexican and Native American men were killed after being buried alive in their shaft when the roof caved in. The men were deep within the shaft so no rescue was possible or attempted, this frightened the Mexican employees who felt the mine was haunted so they left and went home to Sonora. Several German and American miners then ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Unincorporated Community
An unincorporated area is a region that is not governed by a local municipal corporation. Widespread unincorporated communities and areas are a distinguishing feature of the United States and Canada. Most other countries of the world either have no unincorporated areas at all or these are very rare: typically remote, outlying, sparsely populated or uninhabited areas. By country Argentina In Argentina, the provinces of Chubut, Córdoba, Entre Ríos, Formosa, Neuquén, Río Negro, San Luis, Santa Cruz, Santiago del Estero, Tierra del Fuego, and Tucumán have areas that are outside any municipality or commune. Australia Unlike many other countries, Australia has only one level of local government immediately beneath state and territorial governments. A local government area (LGA) often contains several towns and even entire metropolitan areas. Thus, aside from very sparsely populated areas and a few other special cases, almost all of Australia is part of an LGA. Uninc ...

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as 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 most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Mexican Revolution
The Mexican Revolution ( es, Revolución Mexicana) was an extended sequence of armed regional conflicts in Mexico from approximately 1910 to 1920.

United States Cavalry
The United States Cavalry, or U.S. Cavalry, was the designation of the mounted force of the United States Army by an act of Congress on 3 August 1861.Price (1883) p. 103, 104 This act converted the U.S. Army's two regiments of dragoons, one regiment of mounted riflemen, and two regiments of cavalry into one branch of service. The cavalry branch transitioned to the Armored Forces with tanks in 1940, but the term "cavalry", e.g. "armored cavalry", remains in use in the U.S. Army for mounted (ground and aviation) reconnaissance, surveillance, and target acquisition (RSTA) units based on their parent Combat Arms Regimental System (CARS) regiment. ''Cavalry'' is also used in the name of the 1st Cavalry Division for heraldic/lineage/historical purposes. Some combined arms battalions (i.e., consisting of a combination of tank and mechanized infantry companies) are designated as ''armor'' formations, while others are designated as ''infantry'' organizations.

Court Of Private Land Claims
A court is any person or institution, often as a government institution, with the authority to adjudicate legal disputes between parties and carry out the administration of justice in civil, criminal, and administrative matters in accordance with the rule of law. In both common law and civil law legal systems, courts are the central means for dispute resolution, and it is generally understood that all people have an ability to bring their claims before a court. Similarly, the rights of those accused of a crime include the right to present a defense before a court. The system of courts that interprets and applies the law is collectively known as the judiciary. The place where a court sits is known as a venue. The room where court proceedings occur is known as a courtroom, and the building as a courthouse; court facilities range from simple and very small facilities in rural communities to large complex facilities in urban communities.

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.
