Sutro Tunnel
The Sutro Tunnel is a drainage tunnel (adit) connected to the Comstock Lode in Northern Nevada. It begins at Dayton, Nevada and connects Northwest to the Savage mine in Virginia City, Nevada. The tunnel was proposed by Adolph Sutro, a Prussian Jewish mining entrepreneur, in 1860. He promoted the drainage tunnel to allow access to deeper mineral exploration in the Comstock. Flooding and inadequate pumps had inhibited some exploration until that time. By 1865, Sutro's idea had gained the approval of state and federal governments. The mining interests of the Comstock initially supported the project, but later opposed the idea. They feared that an alternate access point to the Comstock minerals would threaten their monopoly on the mining and milling of gold and silver in the Comstock. Nonetheless, Sutro formed the Sutro Tunnel Company, selling stock certificates to raise funds for its construction, which began in 1869. Financing also came from local miners motivated by the prospect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adit
An adit (from Latin ''aditus'', entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins. Construction Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the adit is rarely straight. The use of adits for the extraction of ore is generally called drift mining. Adits can only be driven into a mine where the local topography permits. There will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. Also if the ground is weak, the cost of shoring up a long adit may outweigh its possible advantage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nevada Historical Markers ...
Nevada historical markers identify significant places of interest in Nevada's history. The Historic Marker Program was initiated by the Nevada State Legislature in 1967 to bring the state's heritage to the public's attention with on-site markers.

History Of Nevada
The History of Nevada as a state began when it became the 36th state on October 31, 1864, after telegraphing the Constitution of Nevada to the 38th United States Congress, Congress days before the U.S. presidential election, 1864, November 8 presidential election (the largest and costliest transmission ever by telegraph). Statehood was rushed to help ensure three United States Electoral College, electoral votes for Abraham Lincoln's reelection and add to the Republican congressional majorities. Nevada's harsh but rich Natural environment, environment shaped its history and culture. Before 1858 small Mormon settlements existed along the border of Utah, with the western part stumbling along until the great Silver mining, silver strikes beginning in 1858 created boom towns and fabulous fortunes. After the beginning of the 20th century, profits declined while Progressive Party (United States, 1912), progressive reformers sought to curb capitalism. They imagined a civilized Nevada of un ...

Buildings And Structures In Storey County, Nevada
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tunnels Completed In 1878
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Year 187 (Roman numerals, CLXXXVII) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar.

Silver Mining In The United States
Silver mining in the United States began on a major scale with the discovery of the Comstock Lode in Nevada in 1858. The industry suffered greatly from the demonetization of silver in 1873 by the Coinage Act of 1873, known pejoratively as the " Crime of 73", but silver mining continues today. United States mines produced 1,170 tons of silver in 2014, 17% of the silver it used. 63% of consumption was imported, from Mexico, Canada, Peru and Chile, and the remainder was derived from recycling. Three US mines had silver as their primary product, and 39 mines reported silver as a byproduct of gold and base metals production. Alaska was the country's leading silver-producing state, followed by Nevada and Idaho. Interest in silver mining increased in recent years because of an increased price for the metal: the average silver price increased from $4.39 per troy ounce for the year 2001, to $13.45 per troy ounce for 2007. In 2011, silver prices rose to almost $49 per troy ounce in April be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining In Nevada
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, Refining, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include Metal#Extraction, metals, coal, oil shale, gemstones, limestone, chalk mining, chalk, dimension stone, Sodium chloride, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agriculture, agricultural processes, or feasibly created Chemical synthesis, 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 fossil water, water. Modern mining processes involve prospecting for ore ...
