Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Territory Of Jefferson
The Territory of Jefferson was an extralegal and unrecognized United States territory that existed from October 24, 1859 until the creation of the Colorado Territory on February 28, 1861. The Jefferson Territory, named for Founding Father and United States president Thomas Jefferson, included land officially part of the Kansas Territory, the Nebraska Territory, the New Mexico Territory, the Utah Territory, and the Washington Territory, but the area was remote from the governments of those five territories. The government of the Jefferson Territory, while democratically elected, was never legally recognized by the United States government, although it managed the territory with relatively free rein for 16 months. Many of the laws enacted by the Jefferson Territorial Legislature were reenacted and given official sanction by the new Colorado General Assembly in 1861. Origins On August 25, 1855, the Kansas Territory created Arapahoe County, a huge county that included the entire w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territory Of Nebraska
The Territory of Nebraska was an organized incorporated territory of the United States that existed from May 30, 1854, until March 1, 1867, when the final extent of the territory was admitted to the Union as the State of Nebraska. The Nebraska Territory was created by the Kansas–Nebraska Act of 1854. The territorial capital was Omaha. The territory encompassed areas of what is today Nebraska, Wyoming, South Dakota, North Dakota, Colorado, and Montana. History An enabling act was passed by Congress in 1864. Delegates for a constitutional convention were elected; this convention did not produce a constitution. Two years later, in 1866, a constitution was drafted and voted upon. It was approved by 100 votes. However, a clause in this constitution that limited suffrage to "free white males" delayed Nebraska's entry into the Union for almost a year. The 1866 enabling act for the state was subject to a pocket veto by President Andrew Johnson. When Congress reconvened in 1867, it ...

Pike's Peak Gold Rush
The Pike's Peak Gold Rush (later known as the Colorado Gold Rush) was the boom in gold prospecting and mining in the Pike's Peak Country of western Kansas Territory and southwestern Nebraska Territory of the United States that began in July 1858 and lasted until roughly the creation of the Colorado Territory on February 28, 1861. An estimated 100,000 gold seekers took part in one of the greatest gold rushes in North American history. The participants in the gold rush were known as " Fifty-Niners" after 1859, the peak year of the rush and often used the motto Pike's Peak or Bust! In fact, the location of the Pike's Peak Gold Rush was centered north of Pike's Peak. The name Pike's Peak Gold Rush was used mainly because of how well known and important Pike's Peak was at the time. Overview The Pike's Peak Gold Rush, which followed the California Gold Rush by approximately one decade, produced a dramatic but temporary influx of migrants and immigrants into the Pike's Peak Country o ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as 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 most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

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. As defined by the United States Census, "Native Americans" are Indigenous tribes that are originally from the contiguous United States, along with Alaska Natives. 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 ...

Arapaho Nation
The Arapaho (; french: Arapahos, ) are a Native American people historically living on the plains of Colorado and Wyoming. They were close allies of the Cheyenne tribe and loosely aligned with the Lakota and Dakota. By the 1850s, Arapaho bands formed two tribes, namely the Northern Arapaho and Southern Arapaho. Since 1878, the Northern Arapaho have lived with the Eastern Shoshone on the Wind River Reservation in Wyoming and are federally recognized as the Arapahoe Tribe of the Wind River Reservation. The Southern Arapaho live with the Southern Cheyenne in Oklahoma. Together, their members are enrolled as the federally recognized Cheyenne and Arapaho Tribes. Names It is uncertain where the word 'Arapaho' came from. Europeans may have derived it from the Pawnee word for "trader", ''iriiraraapuhu'', or it may have been a corruption of a Crow word for "tattoo", ''alapúuxaache''. The Arapaho autonym is or ("our people" or "people of our own kind"). They refer to their tribe as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territory Of Kansas
The Territory of Kansas was an organized incorporated territory of the United States that existed from May 30, 1854, until January 29, 1861, when the eastern portion of the territory was admitted to the Union as the free state of Kansas. The territory extended from the Missouri border west to the summit of the Rocky Mountains and from the 37th parallel north to the 40th parallel north. Originally part of Missouri Territory, it was unorganized from 1821 to 1854. Much of the eastern region of what is now the State of Colorado was part of Kansas Territory. The Territory of Colorado was created to govern this western region of the former Kansas Territory on February 28, 1861. The question of whether Kansas was to be a free or a slave state was, according to the Compromise of 1850 and the Kansas–Nebraska Act, to be decided by popular sovereignty, that is, by vote of the Kansans. The question of who were the Kansans who were eligible to vote ended up causing armed conflict, cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arapahoe County, Kansas Territory
Arapahoe County was a county of Kansas Territory in the United States that existed from August 25, 1855, until Kansas's admission into the Union on January 29, 1861. History On August 25, 1855, the Kansas Territorial Legislature created Arapahoe County to govern the western portion of Kansas Territory (in what is now Colorado). The county was named for the Arapaho Nation of Native Americans that lived in the region. In July 1858, gold was discovered along the South Platte River in Arapahoe County, precipitating the Pike's Peak Gold Rush. To provide local government for the gold mining region, the Kansas Territorial Legislature split Arapahoe County into six counties on February 7, 1859: a much smaller Arapahoe County, Broderick County, El Paso County, Fremont County, Montana County, and Oro County. None of these six counties were ever organized. Many residents of the mining region felt disconnected from the territorial government, which was seated nearly 600 miles away, a ...
