Ajo, Arizona
Ajo ( ) is an unincorporated community in Pima County, Arizona, United States. It is the closest community to Organ Pipe Cactus National Monument. The population was 3,304 at the 2010 census. Ajo is located on State Route 85 just from the Mexican border. History ''Ajo'' is the Spanish word for garlic (). The Spanish may have named the place using the familiar word in place of the similar-sounding O'odham word for paint (''oʼoho''). The Tohono O'odham people obtained red paint pigments from the area. Native Americans, Spaniards, and Americans have all extracted mineral wealth from Ajo's abundant ore deposits. In the early nineteenth century, there was a Spanish mine nicknamed "Old Bat Hole" that was abandoned due to Indian raids. Tom Childs, Sr., found the deserted mine complete with a shaft, mesquite ladders, and rawhide buckets in 1847. He did not stay long at that time, because he was on his way to the silver mines near Magdalena de Kino, Sonora. Thirty-five ye ...

Arizona State Route 85
State Route 85 (SR 85) is a state highway in the U.S. state of Arizona. The highway runs from the United States–Mexico border near Lukeville to the north ending at Interstate 10 (I-10) in Buckeye. The highway also intersects I-8 in Gila Bend and serves as a connector between I-8 and I-10 and for travelers between Phoenix and Yuma as well as San Diego. SR 85 between I-10 and I-8, as well as I-8 between SR 85 and I-10 in Casa Grande, is touted as a bypass of the Phoenix area for long-distance travelers on I-10. SR 85 was established in 1936 as a route between Gila Bend and Ajo. It was extended southward to the Mexican border in 1955, and was extended northward to Phoenix when it replaced U.S. Route 80 (US 80) in 1977. The northern end of the highway was realigned in 1994 onto the connecting highway between I-10 and Buckeye. The remaining portion of the highway between Buckeye and Phoenix was gradually turned over to the cities and county along the route ...

Peter Rainsford Brady
Peter Rainsford Brady (August 4, 1825 – May 2, 1902) was an American military officer, surveyor and politician. Following a short service in the United States Navy he joined the Texas Rangers, where he served during the Mexican–American War and along the western frontier. From Texas he moved westward where he became an early settler and political office holder in Arizona Territory. Background Brady was born to Peter and Ann (Rainsford) Brady on August 4, 1825, in the Georgetown section of Washington, D.C. The dates given for Brady's stay at the Naval Academy, 1844–1846, and the date of his company in the Texas Rangers, 1847, though at variance with some sources, appear to be most credible. His mother was a Londoner. She married a citizen of Georgetown at age 21. Besides Peter they had two daughters, Margaret Ann and Mary Ellen. Peter was educated at Georgetown College, starting at age 12. This event is not to be judged by today's educational system, which did not th ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Rawhide (textile)
Rawhide is a hide or animal skin that has not been exposed to tanning. It is similar to parchment, much lighter in color than leather made by traditional vegetable tanning. Rawhide is more susceptible to water than leather, and it quickly softens and stretches if left wet unless well waterproofed. "Rawhide" laces often sold for boots or baseball gloves are made of normal tanned leather rather than actual rawhide. Rawhide is not pliable when dry and would be unsuitable for that use. Process The skin from buffalo, deer, elk or cattle from which most rawhide originates is prepared by removing all fur, meat and fat. The hide is then usually stretched over a frame before being dried. The resulting material is hard and translucent. It can be shaped by rewetting and forming before being allowed to thoroughly re-dry. It can be rendered more pliable by 'working', i.e. bending repeatedly in multiple directions, often by rubbing it over a post, sometimes traditionally by chewing. It may ...

Mesquite
Mesquite is a common name for several plants in the genus ''Prosopis'', which contains over 40 species of small leguminous trees. They are native to dry areas in the Americas. They have extremely long roots to seek water from very far under ground. As a legume, mesquites are one of the few sources of fixed nitrogen in the desert habitat. These trees bloom from spring to summer. They often produce fruits known as "pods". ''Prosopis'' spp. are able to grow up to tall, depending on site and climate. They are deciduous and depending on location and rainfall have either deep or shallow roots. ''Prosopis'' is considered long-lived because of the low mortality rate after the dicotyledonous stage and juveniles are also able to survive in conditions with low light and drought. The Cahuilla indigenous people of western North America were known to eat the seeds of mesquite. History ''Prosopis'' spp. have been in North America since the Pliocene era and their wood has been dated to 3300 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

Native Americans In The United States
Native Americans, also known as American Indians, First Americans, Indigenous Americans, and other terms, are the Indigenous peoples of the mainland United States ( Indigenous peoples of Hawaii, Alaska and territories of the United States are generally known by other terms). There are 574 federally recognized tribes living within the US, about half of which are associated with Indian reservations.

Indigenous peoples of the United States who are not listed as American Indian or Alaska Native include Native Hawaiians, Samoan Americans, and the Chamorro people. The US Census groups these peoples as " Native Hawaiian and other Pacific Islanders". European colonization of the Americas, which began in 1492, resulted in a precipitous decline in Native American population because of new diseases, wars, ethni ...

Pigments
A pigment is a colored material that is completely or nearly insoluble in water. In contrast, dyes are typically soluble, at least at some stage in their use. Generally dyes are often organic compounds whereas pigments are often inorganic compounds. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli. Economic impact In 2006, around 7.4 million tons of inorganic, organic, and special pigments were marketed worldwide. Estimated at around US$14.86 billion in 2018 and will rise at over 4.9% CAGR from 2019 to 2026. The global demand for pigments was roughly US$20.5 billion in 2009. According to an April 2018 report by ''Bloomberg Businessweek'', the estimated value of the pigment industry globally is $30 billion. The value of titanium dioxide – used to enhance the white brightness of many products – was placed at $13.2 billion per year, while the color Ferrari red is valued at $300 million each year.
