Idaho Batholith
The Idaho Batholith is a granitic and granodioritic batholith of Cretaceous- Paleogene age that covers approximately of central Idaho and adjacent Montana. The batholith has two lobes that are separate from each other geographically and geologically. The Bitterroot lobe is the smaller lobe and the larger lobe is the Atlanta lobe. The Bitterroot lobe is in the north and is separated from the larger Atlanta lobe in the south by the Belt Supergroup metamorphic rocks that compose the Salmon River Arch. Much of the Atlanta and Bitterroot lobes are in the Idaho Batholith ecoregion. The overall intrusive event that created the Idaho batholith lasted for around 55 million years from Late Cretaceous to the Eocene (98 to 43 Ma) of magmatism and includes the younger Challis suite which is not considered to be part of the Idaho Batholith. The Challis suite intruded both the Atlanta and Bitterroot lobes of the Idaho Batholith as well as the surrounding areas to the east of the Atlan ...

Gold Mining In The United States
In the United States, gold mining has taken place continually since the discovery of gold at the Reed Gold Mine, Reed farm in North Carolina in 1799. The first documented occurrence of gold was in Virginia in 1782. Some minor gold production took place in North Carolina as early as 1793, but created no excitement. The discovery on the Reed farm in 1799 which was identified as gold in 1802 and subsequently mined marked the first commercial production. The large scale production of gold started with the California Gold Rush in 1848. The closure of gold mines during World War II by the War Production Board Limitation Order No. 208 in autumn 1942 was a major impact on the production until the end of the war. US gold production greatly increased during the 1980s, due to high gold prices and the use of heap leaching to recover gold from disseminated low-grade deposits in Nevada and other states. In 2019 the United States produced 200 tonnes (6.4 million troy ounces) of gold (down from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prospecting
Prospecting is the first stage of the geological analysis (followed by Mining engineering#Pre-mining, exploration) of a territory. It is the search for minerals, fossils, precious metals, or mineral specimens. It is also known as fossicking. Traditionally prospecting relied on direct observation of mineralization in rock outcrops or in sediments. Modern prospecting also includes the use of geologic, Geophysics, geophysical, and Geochemistry, geochemical tools to search for anomalies which can narrow the search area. Once an anomaly has been identified and interpreted to be a potential prospect direct observation can then be focused on this area. In some areas a prospector must also stake a claim, meaning they must erect posts with the appropriate placards on all four corners of a desired land they wish to prospect and register this claim before they may take samples. In other areas publicly held lands are open to prospecting without staking a mining claim. Historical method ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Trapping
Animal trapping, or simply trapping or ginning, is the use of a device to remotely catch and often kill an animal. Animals may be trapped for a variety of purposes, including for meat, fur trade, fur/feathers, sport hunting, pest control, and wildlife management. History Neolithic hunters, including the members of the Cucuteni-Trypillian culture of Romania and Ukraine (), used traps to capture their prey. An early mention in written form is a passage from the self-titled book by Taoism, Taoist philosopher Zhuangzi (book), Zhuangzi which describes Chinese methods used for trapping animals during the 4th century BCE. The Zhuangzi reads: "The sleek-furred fox and the elegantly spotted leopard ... can't seem to escape the disaster of nets and traps." "Modern" steel jaw-traps were first described in western sources as early as the late 16th century. The first mention comes from Leonard Mascall's book on animal trapping. It reads: "a griping trappe made all of yrne, the lowest b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oregon Pioneer History
Oregon pioneer history (1806–1890) is the period in the history of Oregon Country and Oregon Territory, in the present day state of Oregon and Northwestern United States. It was the era when pioneers and mountain men, primarily of European descent, traveled west across North America to explore and settle the lands west of the Rocky Mountains and north of California. Some also arrived via the Pacific Ocean, traveling by ship either around Cape Horn or by changing ships at Panama. The period begins after the explorations of the lower Columbia River by Robert Gray and George Vancouver in 1792, along with the 1804–1806 Lewis and Clark Expedition to Oregon Country, and runs until circa 1890 when railroads and urban centers created a more settled state. Territory At the beginning of the pioneer period the Oregon Country was the homeland of numerous tribes of Native Americans. Portions of the area were claimed by the United States, Great Britain, Spain, and Russia. From 1818 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shoshone
The Shoshone or Shoshoni ( or ), also known by the endonym Newe, are an Native Americans in the United States, Indigenous people of the United States with four large cultural/linguistic divisions: * Eastern Shoshone: Wyoming * Northern Shoshone: Southern Idaho * Western Shoshone: California, Nevada, and Northern Utah * Goshute: western Utah, eastern Nevada They traditionally speak the Shoshoni language, part of the Numic languages branch of the large Uto-Aztecan languages, Uto-Aztecan language family. The Shoshone were sometimes called the Snake Indians by neighboring tribes and early American explorers. Their peoples have become members of List of federally recognized tribes, federally recognized tribes throughout their traditional areas of settlement, often co-located with the Northern Paiute people of the Great Basin. Etymology The name "Shoshone" comes from ''Sosoni'', a Shoshoni language, Shoshone word for high-growing grasses. Some neighboring tribes call the Shoshone ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Lewisia Sacajaweana
''Lewisia sacajaweana'' is a species of flowering plant in the family Montiaceae known by the common name Sacajawea's bitterroot. It is endemic to Idaho, where it is known from approximately two dozen sites, with about 75 percent of them in Boise National Forest. It is usually found at elevations ranging from to above sea level and produces white flowers shortly after snowmelt. The species is named in honor of Sacagawea, Native American guide to the Lewis and Clark Expedition. It is part of a genus named for Meriwether Lewis Meriwether Lewis (August 18, 1774 – October 11, 1809) was an American explorer, soldier, politician, and public administrator, best known for his role as the leader of the Lewis and Clark Expedition, also known as the Corps of Discovery, with ... of the same expedition.

Spruce-fir Forests
A spruce is a tree of the genus ''Picea'' ( ), a genus of about 40 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal (taiga) regions of the Northern hemisphere. ''Picea'' is the sole genus in the subfamily Piceoideae. Spruces are large trees, from about 20 to 60 m (about 60–200 ft) tall when mature, and have whorled branches and conical form. Spruces can be distinguished from other genera of the family Pinaceae by their needles (leaves), which are four-sided and attached singly to small persistent peg-like structures (pulvini or sterigmata) on the branches, and by their cones (without any protruding bracts), which hang downwards after they are pollinated. The needles are shed when 4–10 years old, leaving the branches rough with the retained pegs. In other similar genera, the branches are fairly smooth. Spruce are used as food plants by the larvae of some Lepidoptera (moth and butterfly) species, such as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
