Owyhee Mountains
The Owyhee Mountains are a mountain range in Owyhee County, Idaho and Malheur County, Oregon. Mahogany Mountain and the associated volcanic craters of the Lake Owyhee volcanic field are in the Owyhee Mountains of Oregon just east of the Owyhee Reservoir on the Owyhee River. The southeastern end of the range including the old mining area west of Silver City is referred to as the Silver City Range.''Murphy, Idaho,'' 30x60 Minute Topographic Quadrangle, USGS, 1986 About west of Silver City is the De Lamar ghost town in Jordan Creek below the mine workings on De Lamar Mountain to the south. The area was active in the late 1880s.

Jordan Creek (Owyhee River)
Jordan Creek is a tributary of the Owyhee River in the northwestern United States. It generally flows west from near Silver City, Idaho, in the Owyhee Mountains to near Rome in the Oregon High Desert. Major tributaries are Big Boulder, Soda, Louse, Spring, Rock, Meadow, Combination, and Louisa creeks in Idaho and Cow Creek in Oregon.NRCS, p. 10 The creek is named for Michael M. Jordan, who led a party that discovered gold along the creek in 1863. Watershed Jordan Creek's watershed of is almost evenly divided between the two states, 46 percent in Idaho and 54 percent in Oregon. Although the upper parts of the basin in the Silver City Mountain Range supported mining camps and towns in the late 19th century through the early 20th century, they were generally abandoned when the gold and silver played out.Idaho DEQ, pp. 31–32 Much of the population in the 21st century lives on small homesteads, ranches, and farms scattered throughout the watershed.

Mountain Ranges Of Malheur County, Oregon
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains te ...

Landforms Of Owyhee County, Idaho
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...

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] |
Silver
Silver is a chemical element; it has Symbol (chemistry), symbol Ag () and atomic number 47. A soft, whitish-gray, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is found in the Earth's crust in the pure, free elemental form ("native metal, 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 the seven metals of antiquity, silver has had an enduring role in most human cultures. Other than in currency and as an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Pit Mine
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique that extracts rock or minerals from the earth. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface where the overburden is relatively thin. In contrast, deeper mineral deposits can be reached using underground mining. Open-pit mining is considered one of the most dangerous sectors in the industrial world. It causes significant effects to miners' health, as well as damage to the ecological land and water. Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, open-pit produces harmful pollutants depending on the type of mineral being mined, and the type of mining process being used. Extraction Miners typically drill a series of test holes to locate an underground ore body. From th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Lamar, Idaho
De Lamar (also DeLamar) is a ghost town in Owyhee County, Idaho, United States. Its elevation is , and it is approximately west of Silver City. The community lies within an area governed by the Bureau of Land Management. The community formed around the De Lamar Mine, which was established in 1888. Named for mining magnate and former sea captain Joseph Raphael De Lamar, the mine and community quickly boomed and busted, declining after 1890. Despite the community's decline, it continued to exist as a populated community for several decades; it was the location of a summer-only post office from 1917 to 1930. In 1976, the ghost town was listed on the National Register of Historic Places as a historic district. Although the district included an area of approximately , only four of the community's buildings remained in sufficient condition to qualify as contributing properties In the law regulating historic districts in the United States, a contributing property or contrib ...

Owyhee County, Idaho
Owyhee County ( ) is a county in the southwestern corner of the U.S. state of Idaho. As of the 2020 census, the population was 11,913. The county seat is Murphy, and its largest city is Homedale. In area it is the second-largest county in Idaho, behind Idaho County. Owyhee County is part of the Boise metropolitan area and contains slightly more than half of the Duck Valley Indian Reservation, which extends over the Nevada border, into Elko County. The majority of the federally recognized Shoshone- Paiute Tribe that is associated with this reservation lives on the Nevada side; its tribal center is in Owyhee, Nevada. History This area was the territory of Western Shoshone, Northern Paiute, and Bannock peoples and their ancestors for thousands of years prior to the arrival of European settlers. Settler interests in securing land and resources spurred conflict and led to the indigenous peoples being forced onto reservations. On December 31, 1863, Owyhee County became th ...

Silver City, Idaho
Silver City is a ghost town in northwestern Owyhee County, Idaho, United States, that is listed on the National Register of Historic Places (NRHP). At its height in the 1880s, it was a gold and silver mining town with a population of around 2,500 and approximately 75 businesses. Description Silver City served as county seat of Owyhee County from 1867 to 1934. Today, the town has about 70 standing buildings, all of which are privately owned. Many of the owners are third- or fourth-generation descendants of the original miners. There are a handful of small businesses, but no gas or service stations. The property is now owned by the federal government, overseen by the Bureau of Land Management. Silver City was founded in 1864 soon after silver was discovered at nearby War Eagle Mountain (elev. ). The settlement grew quickly and was soon considered one of the major cities in Idaho Territory. The first daily newspaper and telegraph office in Idaho Territory were established in Sil ...
