Three thin, pale yellow stripes (known as Cat Whiskers ) extended from the nose logo around the cab sides. In January, 1951, Santa Fe revised
363-711: A combination of factors including the depletion of easily accessible gold deposits, harsh weather conditions, and the political instability at the time. The Welsh gold rush occurred in Wales , more so in the Dolgellau area of Gwynedd , during the 19th century. Gold deposits were discovered in Welsh mountains, with reports of gold being found in rivers Mawddach and Tryweryn . By the mid-19th century, commercial mining operations had begun. Wales' gold gained popularity for its quality and rarity, leading to its use in royal jewelry for
484-722: A critical source of income and livelihood, providing employment opportunities and economic support in regions with limited alternative options. Artisanal mining operations vary in scale, from individuals panning for gold in rivers and streams, to small groups working collectibely in informal mining camps, often referred to as ' galamsey ' in West Africa . Gold mining can create employment opportunities in mining operations and related sectors. Howevers, these jobs may be temporary. The sector's reliance on fluctuating global gold prices can lead to economic stability for communities dependent on mining. The discovery of significant gold deposits in

Some of the more notable locomotives include: Santa Fe maintained and operated a fleet of three passenger ferry boats (the San Pablo , the San Pedro , and the Ocean Wave ) that connected Richmond, California , with San Francisco by water. The ships traveled the eight miles between the San Francisco Ferry Terminal and
1089-471: A large scale to extract gold from extensive alluvial (loose sediment) deposits, such as those at Las Medulas . Mining was under the control of the state but the mines may have been leased to civilian contractors some time later. The gold served as the primary medium of exchange within the empire, and was an important motive in the Roman conquest of Britain by Claudius in the first century AD; although there
1210-488: A lower grade. Tailings can contain lead, mercury, cadmium, and arsenic. These toxins can pose health risks for local communities. Arsenic is typically found in gold-containing ores, and gold processing may contaminate groundwater or the atmosphere. This pollution may persist for decades. Furthermore, mining operations use large quantities of water for processing ore and can result in the contamination of water sources with heavy metals, such as mercury and cyanide , used in
1331-542: A merger between the parent companies of the Santa Fe and Southern Pacific (SP) railroads in 1984. The red, yellow, and black paint scheme with large yellow block letters on the sides and ends of the units of the proposed Southern Pacific Santa Fe Railroad (SPSF) has come to be somewhat derisively known among railfans as the Kodachrome livery, due to the similarity in colors to the boxes containing slide film sold by

"SANTA FE" was displayed on the horizontal limb of the cross in black, Art Deco -style lettering. This emblem has come to be known as the " cigar band " due to its uncanny resemblance to
1815-416: A pair of blunt-nosed units ( EMC 1800 hp B-B ) designated as Nos. 1 and 1A. The upper portion of the sides and ends of the units were painted gold, while the lower section was a dark olive green color; an olive stripe also ran along the sides and widened as it crossed the front of the locomotive. Riveted to the sides of the units were metal plaques bearing a large "Indian Head" logo , which owed its origin to
1936-513: A region often sees a flood of resources and development, which lasts as long as the mines are economic. When goldfields begin to decline in production, local economies find themselves destabilised and overly reliant upon an industry that will inevitably abandon the region when gold deposits are sufficiently depleted; leaving the areas without proper rehabilitation. Atchison, Topeka %26 Santa Fe Railway The Atchison, Topeka and Santa Fe Railway ( reporting mark ATSF ), often referred to as
2057-467: A short time, Pacific types 1369 and 1376 were semi-streamlined for " Valley Flyer " service, with a unique paint scheme in colors similar to those used on the new passenger diesels. Unique was the two-tone light blue over royal blue scheme of streamlined Hudson type 3460 . Santa Fe's first set of diesel-electric passenger locomotives was placed in service on the Super Chief in 1936, and consisted of
2178-747: A tributary of the Klondike River by George Carmack and his Indigenous companions, Skookum Jim Mason and Tagish Charlie . As prospectors arrived in Klondike, makeshift towns and settlements sprang up along the rivers, including Dawson City , which because the largest town in Yukon at the height of the gold rush. Prospectors employed various mining techniques to extract gold from the Klondike's streams and riverbeds, including placer mining, dredging, and hydraulic mining. The Carlin Trend of Nevada, U.S.,
2299-464: A unified worldwide gold company. Shareholders of both companies had identical interests in the reserves, production and earnings of Newmont Gold's operations. Newmont then merged with Santa Fe Railroad (a former Atchison, Topeka & Santa Fe Railway subsidiary, sold in preparation for the merger that produced the BNSF ) to form North America's largest gold producer. On June 21, 2000, Newmont announced
2420-479: A variation of the "Warbonnet" scheme in which the black and yellow separating stripes disappeared. The "Santa Fe" name was emblazoned on the sides in large black letters, using the same stencils used on freight engines; these were soon repainted in red. In 1989, Santa Fe resurrected this version of the "Warbonnet" scheme and applied it to two SDFP45 units, #5992 and #5998. The units were re-designated as #101 and #102 and reentered service on July 4, 1989, as part of
2541-418: Is a cyanide extraction method, or gold cyanidation, introduced in the late 1800s. This a metallurgical technique used to extract gold from lower grade ores by converting gold into a water-soluble coordination complex. Finely ground rock is treated with a solution of sodium cyanide . The extract is absorbed onto carbon and then removed from the carbon with a solution of caustic soda and cyanide. Gold cyanide
SECTION 20
#17327934008602662-429: Is a method of extracting gold from alluvial deposits such as sand, gravel, and sediment. These are known as placer deposits which are typically found in riverbeds, stream beds, and floodplains. These deposits typically contain minerals that are resistant to weathering and eroision like gold , platinum , diamonds , and more. They are characterized by their relatively high concentration of valuable minerals compared to
2783-415: Is characterized by its low cost, as each rock is moved only once. It also has low environmental impact, as no stripping of vegetation or overburden is necessary, and all process water is fully recycled. Such operations are typical on New Zealand's South Island and in the Klondike region of Canada. Also called a cradle, a rocker box uses riffles located in a high-walled box to trap gold in a similar manner to
2904-616: Is done by small-scale miners using suction dredges. These are small machines that float on the water and are usually operated by one or two people. A suction dredge consists of a sluice box supported by pontoons, attached to a suction hose which is controlled by a miner working beneath the water. This method is particularly popular in areas where gold is found at river bottoms or submerge deposits . Suction dredging can have environmental impacts, moreso on aquatic habitats and water quality. Regulations and best practices are often in place to minimize these impacts. State dredging permits in many of
3025-436: Is essentially a man made channel with riffles set in the bottom. The riffles are designed to create dead zones in the current to allow gold to drop out of suspension. The box is placed in the stream to channel water flow. Gold-bearing material is placed at the top of the box. The material is carried by the current through the volt where gold and other dense material settles out behind the riffles. Less dense material flows out of
3146-868: Is estimated that the total gold production in Karnataka to date is 1000 tons. The mining of the Hungarian deposit (present-day Slovakia) primarily around Kremnica was the largest of the Medieval period in Europe. In South America, gold mining in the Andes dates back to thousands of years, with the Inca empire employing extensive gold mining operations in regions such as present-day Peru and Ecuador . They used stone tools and simple mining techniques to extract gold from rivers, streams, and surface deposits. During

Newmont has purchased and sold a number of operations in recent years: Gold mining Gold mining is the extraction of gold by mining . Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning . The expansion of gold mining to ores that are not on
3388-698: Is only one known Roman gold mine at Dolaucothi in west Wales. Gold was a prime motivation for the campaign in Dacia when the Romans invaded Transylvania in what is now modern Romania in the second century AD. The legions were led by the emperor Trajan, and their exploits are shown on Trajan's Column in Rome and the several reproductions of the column elsewhere (such as the Victoria and Albert Museum in London ). Under

Around 4.5 million of them are women, and an estimated 600,000 children work in illegal artisanal gold mines. Artisanal miners use rudimentary methods to extract and process gold. Many of these people are mining to escape extreme poverty , unemployment and landlessness . In Ghana, galamsey miners are estimated to number 20,000 to 50,000. In neighboring francophone countries, such workers are called orpailleurs . In Brazil, Venezuela, Suriname, and French Guiana, workers are called garimpeiros . These workers are not required to claim responsibility for their social and environmental impacts. Miners risk government persecution, mine shaft collapses, and toxic poisoning from unsafe chemicals used in processing, such as mercury. For example, in Ghana during 2009,
3630-446: Is reminiscent of a Native American ceremonial head-dress . The scheme consisted of a red "bonnet" that wrapped around the front of the unit and was bordered by a yellow stripe and black pinstripe. The extent of the bonnet varied according to the locomotive model and was largely determined by the shape and length of the car body. The remainder of the unit was either painted silver or was composed of stainless-steel panels. All units wore
3751-428: Is the largest corporate taxpayer in the country. The mine has generated an environmental conflict , because pollution from the tailings dam and windblown particulates have contaminated rivers and killed local livestock who ingested the toxins. Local communities say that the mine has ruined their lives and caused many health problems: skin lesions are common; children are sickened by chemical vapors; and agricultural land

The mine is run by Pueblo Viejo Dominicana Corporation (PVDC), which is 60% owned by Barrick Gold Corporation and 40% owned by Newmont Corporation. Pueblo Viejo employs approximately 2,350 employees and 2,500 contractors. The economic activities of the mine represent 2% of the Dominican Republic’s gross domestic product and Pueblo Viejo
3993-619: Is the only gold company in the S&;P 500 stock market index. The Newmont Company was founded in 1916 in New York by Colonel William Boyce Thompson as a holding company to invest in Worldwide mineral , oil , and related companies. According to company lore, the name "Newmont" is a portmanteau "New York" and "Montana", reflecting where Thompson made his fortune and where he grew up. Newmont made its first major gold investment in 1917, with
4114-633: Is then converted to relatively pure gold through gold parting . There are many environmental hazards associated with this extraction method, largely due to the high toxicity of the cyanide compounds. Furthermore, there are potentials for accidental spills or leaks to cause harm to aquatic ecosystems and human health. For example, in 2000, the Baia Mare cyanide spill in northern Romania released approximately 100,000 cubic metres (3,500,000 cu ft) of waste water contaminated with heavy metal sludge and up to 120 long tons (122 t) of cyanide into
4235-532: Is unknown, but some of the oldest known gold artifacts were found in the Varna Necropolis in Bulgaria . The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 6,724 years old. During a series of excavations carried out between 1878 and 1992, several graves were found with more than 6kg of gold. A group of German and Georgian archaeologists claims

In 1987, defending against a $ 6.3 billion bid by T. Boone Pickens,
4477-635: The British royal family . During the 19th century, numerous gold rushes in remote regions around the globe caused large migrations of miners, such as the California Gold Rush of 1849. This is one of the most famous gold rushes in history. The discovery of gold at Sutter's Mill in California sparked a massive migration of people from around the world to California in search of gold. The rush significantly accelerated westward expansion in

Archaeological evidence suggests that humans were mining gold as far back as 4000 BCE, with some the earliest known gold artifacts dating back to ancient Mesopotamia . Particularly in the region of present-day Iraq, gold
5687-729: The Santa Fe or AT&SF , was one of the largest Class 1 railroads in the United States between 1859 and 1996. The Santa Fe was a pioneer in intermodal freight transport ; at various times, it operated an airline, the short-lived Santa Fe Skyway, and the Santa Fe Railroad tugboats . Its bus line extended passenger transportation to areas not accessible by rail, and ferryboats on the San Francisco Bay allowed travelers to complete their westward journeys to

Discontinued were the San Francisco Chief , the ex- Grand Canyon , the Tulsan , and a Denver–La Junta local. ATSF had been more than willing to retain the San Diegan and its famed Chiefs. However, any railroad that opted out of Amtrak would have been required to operate all of its passenger routes until at least 1976. The prospect of having to keep operating its less-successful routes, especially
5929-517: The Tisza River. Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. First, the gold ore is crushed and ground to a fine powder to expose the gold particles for amalgamation. Then, this finely ground ore is mixed with liquid mercury to amalgamate it. Mercury forms an amalgam, an alloy, with gold particles to allow for
6050-564: The 1860s. The original shops were relocated in 1878 to the south side of Seward Avenue and expanded in 1902 to double the repair capacity. The shops at Albuquerque , New Mexico, were built in 1880 and materially expanded in 1925. Another shop site was established at San Bernardino , California, in 1886. To maintain rolling stock in the state of Texas, a fourth major shop facility was built in Cleburne, Texas , in 1899. Physical confrontations led to two years of armed conflict that became known as

These rushes were often small-scale and localised compared to later rushes in history. The Transylvania gold rush took place in the Kingdom of Hungary (present-day Romania ), primarily in the region of Transylvania during the medieval period. Transylvania was known for its rich mineral resources including gold, silver, and other metals. Miners in Transylvania used both surface and underground mining techniques to extract gold from alluvial deposits and veins. These methods include panning, sluicing, and rudimentary shaft mining. The Scottish gold rush occurred in Scotland, primarily in

In 2017, Newmont produced 5.65 million ounces of gold at all-in sustaining costs of US$ 924 per ounce. The company reported adjusted net income of $ 780 million for the year, and further reduced net debt down to US$ 0.8 billion. In 2019, it acquired Canada's Goldcorp for $ 10 billion. In May 2023, Newmont agreed terms to purchase Newcrest . The Deal
8591-401: The company eliminated its 1.5 million ounce legacy hedge book to make Newmont the world's largest unhedged gold producer. The following year, Newmont acquired Miramar Mining Corporation and its Hope Bay deposit in the Canadian Arctic. In 2009, Newmont purchased the remaining one-third interest in Boddington Gold Mine from AngloGold Ashanti, bringing its ownership to 100 percent. In April 2011,
8712-474: The company paid a US$ 33 per share special dividend to all shareholders , US$ 2.2 billion in cash, of which US$ 1.75 billion was borrowed. To reduce this debt the company undertook a divestment program involving all of its copper, oil, gas, and coal interests. As a further step in the restructuring, the company moved its headquarters from New York City to Denver in 1988. A decade later, Newmont Mining Corporation and Newmont Gold Company combined assets to form
8833-506: The company's Minahasa Raya mine polluted Buyat Bay . The company was cleared by an Indonesian court, with the judge ruling the pollution charges could not be proven. In 2009, a group of NGOs awarded Newmont with the Public Eye on Davos award (a criticism for "purely profit-oriented globalization") for its Akyem project in Ghana. Newmont said the award was issued based on several paragraphs of text which “clearly were intended to distort
8954-600: The company's exploration geologist. Searls retired in 1954, and Plato Malozemoff took over as president. Newmont began mining at Carlin, Nevada , in 1965. The " Carlin Trend " or "Carlin Unconformity" is the largest gold discovery in North America during the 20th century. In 1971 Newmont began heap leaching low grade ores there. In 1971, the South-West African (now Namibia ) Tsumeb & Kombat mines managed by Newmont, had its operations stopped during
9075-784: The country’s most important railroads and one of the few that directly connected the Midwest with the Gulf of Mexico and the Pacific Ocean under one corporation. The principal lines consisted of Chicago to Kansas City to La Junta, Colorado, to Los Angeles; Emporia, Kansas, to Oklahoma City to Fort Worth to Houston; Emporia, Kansas, to Dalies, New Mexico; Barstow to Richmond, California; Temple to Farwell, Texas; Denver to La Junta, Colorado; Albuquerque, New Mexico, to El Paso, Texas; Dallas to Presidio, Texas; and Kansas City to Tulsa. The primary back shops at Topeka , Kansas, were first established in
9196-432: The efficient capture of gold from the ore. The gold is concentrated by boiling away the mercury from the amalgam . This process is called retorting. This is effective in extracting very small gold particles, but the process is hazardous due to the toxicity of mercury vapour. Large-scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small-scale gold mining (ASGM). While most gold
9317-588: The ends and cab sides to increase the visibility at grade crossings (typically referred to as the Zebra Stripe scheme). "A.T.& S.F." was now placed along the sides of the unit just above the accent stripe, with the blue and white "Santa Fe" box logo below. Due to the lack of abundant water sources in the American desert, the Santa Fe Railway was among the first railroads to receive large numbers of streamlined diesel locomotives for use in freight service, in
9438-762: The extraction process. This pollution can have detrimental effects on aquatic ecosystems and human health. Soil degradation has also been found to be impacted by gold mining. Mining activities can disturb soil structure, leading to erosion, sedimentation of waterways, and loss of fertile land for agriculture or vegetation regrowth. More evidently, dust and emissions from mining machiner and processing facilities can contribute to air pollution, impacting air quality and potentially causings respiratory problems for nearby communities. Large-scale gold mining projects may require land acquisition and resettlement of local communities, leading to displacement, loss of livelihoods, and disruption of traditional ways of life. In addition to
9559-654: The facts”. In 2010, Newmont was fined $ 4.9 million by the Ghanaian Environmental Protection Agency for not preventing, reporting and investigating a cyanide spill at Ahafo mine in an "appropriate and timely manner". Pueblo Viejo mine is an open-pit gold and silver mine in the Sánchez Ramírez Province of the Dominican Republic where mining operations started in 2012 and expect to cease in 2041. It
9680-478: The film The Harvey Girls , a story about the waitresses of the Fred Harvey Company 's restaurants. It was sung in the film by Judy Garland and recorded by many other singers, including Bing Crosby . In the 1970s, the railroad used Crosby's version in a commercial. AT&SF ceased operating passenger trains on May 1, 1971, when it conveyed its remaining trains to Amtrak . These included
9801-504: The form of the EMD FT . For the first group of FTs, delivered between December 1940 and March 1943 (#100–#119), the railroad selected a color scheme consisting of dark blue accented by a pale yellow stripe up the nose, and pale yellow highlights around the cab and along the mesh and framing of openings in the sides of the engine compartment; a thin red stripe separated the blue areas from the yellow. The words SANTA FE were applied in yellow in
9922-694: The gold supply. Most gold is mined in developing nations. Large mining companies play a key role in globalisation of the economy by linking rich and poor companies. Newmont and Barrick Gold are the largest gold mining companies in the world, but there are many smaller corporations in the industry. Local communities are frequently vulnerable to environmental degradation caused by large mining companies and may lack government protection or industry regulation. For example, thousands of people around Lega Dembi mine are exposed to mercury, arsenic, and other toxins resulting in widespread health problems and birth defects. Vulnerable communities may also lose their land to
10043-567: The growth of cities like Melbourne and Sydney . The discovery of gold in the Witwatersrand led to the Second Boer War and ultimately the founding of South Africa. This transformed the region into one of the wealthiest gold-producing areas in the world. This rush played a crucial role in the development of South Africa's economy and lead to the establishment of Johannesburg, known as the 'city of gold'. Gold-bearing reefs in
10164-765: The heat is unbearable for humans, and air conditioning is required for the safety of the workers. The first such mine to receive air conditioning was Robinson Deep , at that time the deepest mine in the world for any mineral. Gold is also produced by mining in which it is not the principal product. Large copper mines, such as the Bingham Canyon mine in Utah, often recover considerable amounts of gold and other metals along with copper. Sand and gravel pits, like those in Denver (Colorado), may recover small amounts of gold in their wash operations. The largest producing gold mine in
10285-415: The image of a passenger carrier. Diesels used as switchers between 1935 and 1960 were painted black, with just a thin white or silver horizontal accent stripe (the sills were painted similarly). The letters "A.T.& S.F." were applied in a small font centered on the sides of the unit, as was the standard blue and white "Santa Fe" box logo. After World War II , diagonal white or silver stripes were added to
10406-595: The invention of the grinding mill . Additionally, gold was associated with the sun god Ra and was believed to be eternal and indestructible, symbolising the pharoah's divine power and afterlife. Gold has also been found in the tombs of Tutankhamun and other pharoahs. During the Bronze Age, gold objects were also plentiful; especially in Ireland and Spain. Romans employed slave labour and used hydraulic mining methods, such as hushing and ground sluicing on
10527-461: The lowest ever recorded for tropical forests, with there being little to no tree regeneration at abandoned mining camps, even after several years. The Amazon rainforest is at risk for 'savannization', which is the gradual transformation of a tropical rainforest into a savannah. This would ultimately lead to a collapse of biodiversity, ecosystems, and climate. Gold mining produces more waste than mining of other minerals, because it can be mined at
10648-729: The middle of the 20th century, Newmont had a controlling interest in the Tsumeb mine in Namibia and in the O'Okiep Copper Company in Namaqualand , South Africa . Beginning in 1925, Newmont acquired interests in a Texas oil field . Eventually, Newmont's oil interests included more than 70 blocks in the Louisiana, Gulf of Mexico area and oil and gas production in the North Sea . Fred Searls became president in 1947, after serving as
10769-663: The mine. Some large companies have attempted to build local legitimacy through corporate responsibility initiatives and local development. Gold mining can significantly alter the natural environment. Gold mining activities in tropical forests are increasingly causing deforestation along rivers and in remote areas rich in biodiversity. Mining has increased rainforest loss up to 70km beyond lease boundaries, causing nearly 11,670 km of deforestation between 2005 to 2015. Up to 9% of gold mining occurs outside of these regulated lease boundaries. Other gold mining impacts, particularly in aquatic systems with residual cyanide or mercury (used in
10890-473: The money-bleeding 23/24 (the former Grand Canyon ) led ATSF to get out of passenger service altogether. Amtrak still runs the Super Chief and San Diegan today as the Southwest Chief and Pacific Surfliner , respectively, although the original routes and equipment have been modified by Amtrak. AT&SF operated the following named trains on regular schedules: Occasionally, a special train
11011-600: The most popular and durable, becoming to the Santa Fe what New York City - Philadelphia trains were to the Pennsylvania Railroad . But Santa Fe flyers also served Tulsa, Oklahoma , El Paso, Texas , Phoenix, Arizona (the Hassayampa Flyer ), and Denver, Colorado , among other cities not on their main line. To reach smaller communities, the railroad operated mixed (passenger and freight) trains or gas-electric doodlebug rail cars . The latter were later converted to diesel power, and one pair of Budd Rail Diesel Cars
11132-744: The neighbouring Free State province were found shortly thereafter, driving significant development in the region with the establishment of the Free State goldfields . Also known as the Yukon Gold Rush , brought prospectors from around the world to the Klondike region of the Yukon territory in Canada . The Klondike Gold Rush began in 1896, when gold was discovered in Bonanza Creek ,
11253-548: The new "Super Fleet" campaign (the first Santa Fe units to be so decorated for freight service). The six remaining FP45 units were thereafter similarly repainted and renumbered. From that point forward, most new locomotives wore red and silver, and many retained this scheme after the Burlington Northern Santa Fe merger, some with "BNSF" displayed across their sides. For the initial deliveries of factory-new "Super Fleet" equipment, Santa Fe took delivery of
11374-413: The old bucket line . This has improved the chances of finding gold. Smaller dredges with 50-to-100-millimetre (2 to 4 in) suction tubes are used to sample areas behind boulders and along potential pay streaks, until "colour" (gold) appears. Other larger scale dredging operations take place on exposed river gravel bars at seasonal low water. These operations typically use a land based excavator to feed
11495-535: The other half, merged the TP&;W in 1983, then sold it back into independence in 1989. AT&SF began merger talks in the 1980s. The Southern Pacific Santa Fe Railroad (SPSF) was a proposed merger between the parent companies of the Southern Pacific and AT&SF announced on December 23, 1983. As part of the joining of the two firms, all rail and non-rail assets owned by Santa Fe Industries and
11616-688: The possible respiratory problems that could be acquired, individuals may be exposed to hazardous chemicals used in gold extraction such as mercury and cyanide. These chemicals pose risks to gold miners, communities, and wildlife; resulting in further medical problems involving neurological disorders and waterborne diseases . Gold mining in some regions has been associated with conflicts over land rights, labour rights violations, and exploitation of vulnerable populations, including Indigenous peoples and artisanal miners. Mining activities can damage or destroy cultural heritage sites, artifacts, and sacred areas; further impacting cultural identities and heritages. In
11737-674: The railroad's Point Richmond terminal across San Francisco Bay. The service was originally established as a continuation of the company's named passenger train runs such as the Angel and the Saint . The larger two ships (the San Pablo and the San Pedro ) carried Fred Harvey Company dining facilities. Rival SP owned the world's largest ferry fleet (which was subsidized by other railroad activities), at its peak carrying 40 million passengers and 60 million vehicles annually aboard 43 vessels. Santa Fe discontinued ferry service in 1933 due to
11858-422: The rare 4-4-6-2 . The railroad retired its last steam locomotive in 1959. During the twentieth century, all but one of these was painted black, with white unit numbers on the sand domes and three sides of the tender. Cab sides were lettered "AT&SF", also in white. The subsidiary Gulf, Colorado and Santa Fe often painted all or part of the smokebox (between the boiler and the headlight) white or silver. In 1940,
11979-407: The recovery of gold from ore), can be highly toxic to people and wildlife even at relatively low concentrations. Illegal gold mining exacerbates the ecological vulnerability of the remaining forest ultimately leading to permanent forest loss. Gold mining clears native forests for mineral extraction, but also indirectly facilitates access to more land and further clearing. Rainforest recovery rates are
12100-416: The same. On all but the " Erie-built " units (which were essentially run as a demonstrator set), GE U28CG , GE U30CG , and FP45 units, a three-part yellow and black stripe ran up the nose behind the band. A "Circle and Cross" motif (consisting of a yellow field, with red quadrants, outlined in black) was painted around the side windows on "as-delivered" E1 units. Similar designs were added to E3s , E6s ,
12221-433: The scheme to consist of three yellow stripes running up the nose, with the addition of a blue and yellow Cigar Band (similar in size and shape to that applied to passenger units); the blue background and elongated yellow "SANTA FE" lettering were retained. The years 1960 to 1972 saw non-streamlined freight locomotives sporting the "Billboard" color scheme (sometimes referred to as the "Bookends" or "Pinstripe" scheme), where
12342-553: The scheme to its gas-electric " doodlebug " units. The standard for all of Santa Fe's passenger locomotives, the Warbonnet is considered by many to be the most-recognized corporate logo in the railroad industry. Early after Amtrak's inception in 1971, Santa Fe embarked on a program to repaint the red bonnet on its F units that were still engaged in hauling passenger consists with yellow (also called Yellowbonnets ) or dark blue (nicknamed Bluebonnets ), as it no longer wanted to project
12463-539: The sides and ends of the units in order to enhance their appearance. In a little over a year, the EMC E1 (a new and improved streamlined locomotive) would be pulling the Super Chief and other passenger consists, resplendent in the now-famous Warbonnet paint scheme devised by Leland Knickerbocker of the GM Art and Color Section. Its design was protected under a U.S. design patent , granted on November 9, 1937. It
12584-549: The sluice box. A rocker box uses less water than a sluice box and is well suited for areas where water is limited. A rocking motion provides the water movement needed for the gravity separation of gold in placer material. Rocker boxes gained popularity during the California Gold Rush in the 19th century and remain in use today. Although simple and inexpensive, it is not efficient as the previously discussed mining techniques . The dominant method for refining gold
12705-541: The sparse population. It set up real estate offices in the area and promoted settlement across Kansas on the land granted to it by Congress in 1863. On March 29, 1955 , the railway was one of many companies that sponsored attractions in Disneyland with its five-year sponsorship of all Disneyland trains and stations until 1974. In 1960, AT&SF bought the Toledo, Peoria & Western Railroad (TP&W); then sold
12826-630: The surface has led to more complex extraction processes such as pit mining and gold cyanidation . In the 20th and 21st centuries, most volume of mining was done by large corporations. However, the value of gold has led to millions of small, artisanal miners in many parts of the Global South . Like all mining, human rights and environmental issues are common in the gold mining industry, and can result in environmental conflict . In mines with less regulation, health and safety risks are much higher. The exact date that humans first began to mine gold
12947-467: The surrounding rock or sediments. Unlike hard-rock mining, which involves excavating solid rock formations, water or dredging is used to extract the gold. Using a sluice box to extract gold from placer deposits has long been a very common practice in prospecting and small-scale mining. Sluices work on the principle that heavier particles will sink to the bottom of a stream, while those that are lighter will be carried downstream and expelled. A sluice box
13068-547: The tracks were laid directly over the wagon ruts of the Santa Fe Trail . In 1869, the first general office building of the company was built in Topeka. This building also served as a passenger station and freight depot. When the line was extended to Newton, Kansas in 1871, the railroad became a major cattle shipper to ensure a steady revenue stream, at the end of Texas cattle drive trails . Despite being chartered to serve
13189-439: The units were predominantly dark blue with yellow ends and trim, with a single yellow accent pinstripe. The words "Santa Fe" were applied in yellow in large bold serif letters (logotype) to the sides of the locomotive below the accent stripe (save for yard switchers which displayed the "SANTA FE" in small yellow letters above the accent stripe, somewhat akin to the Zebra Stripe arrangement). From 1972 to 1996, and even on into
13310-538: The world's gold. Sometimes open-pit mining is used, such as at the Fort Knox Mine in central Alaska. Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in north eastern Nevada. Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths,
13431-720: The world, the Grasberg mine in Papua, Indonesia, is primarily a copper mine. Gold panning , or simply panning , is a form of placer mining and traditional mining that extracts gold from a placer deposit using a pan. The process is one of the simplest ways to extract gold, and is popular with geology enthusiasts especially because of its low cost and relative simplicity. The first recorded instances of placer mining are from ancient Rome , where gold and other precious metals were extracted from streams and mountainsides using sluices and panning ( ruina montium ). Placer mining
13552-663: Was China with 368.3 tonnes of gold mined in that year. The second-largest producer of gold was Russia where 331.1 tonnes was mined in the same year, followed by Australia with 327.8 tonnes. In 2023, the annual gold demand of 4,448 tonnes was 5% below that of 2022. The total gold demand in 2023 was the highest at 4,899 tonnes. Despite its decreasing content in ores, gold production is increasing. This increase can be achieved through ever larger-scale industrial installations as well as innovations, especially in hydrometallurgy . Hard rock mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of
13673-517: Was among the first to add dining cars to its passenger trains, a move which began in 1891, following the examples of the Northern Pacific and Union Pacific railroads. The AT&SF offered food on board in a dining car or at one of the many Harvey House restaurants that were strategically located throughout the system. In general, the same train name was used for both directions of a particular train. The exceptions to this rule included
13794-535: Was chartered in February 1859 to serve the cities of Atchison and Topeka, Kansas , and Santa Fe, New Mexico . The railroad reached the Kansas – Colorado border in 1873 and Pueblo, Colorado , in 1876. To create a demand for its services, the railroad set up real estate offices and sold farmland from the land grants that it was awarded by Congress for laying track. As the railroad was first being built, many of
13915-403: Was chartered to make a high-profile run over the Santa Fe's track. These specials were not included in the railroad's regular revenue service lineup, but were intended as one-time (and usually one-way) traversals of the railroad. Some of the more notable specials include: The Santa Fe employed several distinctive wayside and crossing signal styles. In an effort to reduce grade crossing accidents,
14036-560: Was completed in November 2023. Goldcorp had previously been under public scrutiny for documented human-rights abuses, including poisoning river-water that led to severe illnesses in local children living close to the mining operation ( https://theviolenceofdevelopment.com/the-true-cost-of-gold-in-honduras/ ) In August 2004, the Indonesian Ministry of Environment filed a civil lawsuit against Newmont, claiming tailings from
14157-514: Was discovered in 1961. Official estimates indicate that total world gold production since the beginning of civilization has been around 6,352,216,000 troy ounces (197,576.0 t) and total gold production in Nevada is 1.1% of that, ranking Nevada as one of the Earth's primary gold-producing regions. World gold production was 3,612 tonnes in 2022. As of 2020 , the world's largest gold producer
14278-458: Was eventually added. After World War II, Santa Fe Trailways buses replaced most of these lesser trains. These smaller trains generally were not named; only the train numbers were used to differentiate services. The ubiquitous passenger service inspired the title of the 1946 Academy-Award -winning Harry Warren tune " On the Atchison, Topeka and the Santa Fe ." The song was written in 1945 for
14399-626: Was mined extensively. The ancient Sumerians , around 2500 BCE, developed sophisticated techniques for extracting gold from alluvial deposits and underground mines. These techniques included the use of sluice boxes. Evidence suggests that Nubia had sporadic access to gold nuggets during the Neolithic and Prehistoric Period . Gold mining in Egypt involved both surface mining such as panning for gold in riverbeads and underground mining, where tunnels were dug to extract gold-bearing quartz veins. During
14520-537: Was opened. The Santa Fe was the only railroad to run trains from Chicago to California on its own tracks. The railway's extensive network was also home to a number of regional services. These generally couldn't boast of the size or panache of the transcontinental trains, but built up enviable reputations of their own nonetheless. Of these, the Chicago-Texas trains were the most famous and impressive. The San Diegans , which ran from Los Angeles to San Diego, were
14641-576: Was widely known for its passenger train service in the first half of the 20th century. AT&SF introduced many innovations in passenger rail travel, among these the " Pleasure Domes " of the Super Chief (billed as the " ...only dome car[s] between Chicago and Los Angeles " when they were introduced in 1951) and the " Big Dome " Lounge cars and double-decker Hi-Level cars of the El Capitan , which entered revenue service in 1954. The railroad
