Four Corners
Four Corners is a region of the Southwestern United States consisting of the southwestern corner of Colorado, southeastern corner of Utah, northeastern corner of Arizona, and northwestern corner of New Mexico. Most of the Four Corners region belongs to semi-autonomous Native American nations, the largest of which is the Navajo Nation, followed by Hopi, Ute, and Zuni tribal reserves and nations. The Four Corners region is part of a larger region known as the Colorado Plateau and is mostly rural, rugged, and arid. The Four Corners area is named after the quadripoint at the intersection of approximately 37° north latitude with 109° 03′ west longitude, where the boundaries of the four states meet, and is marked by the Four Corners Monument. It is the only location in the United States where four states meet. In addition to the monument, commonly visited areas within Four Corners include Monument Valley, Mesa Verde National Park, Chaco Canyon, Canyons of the Ancients ...

Four Corners Monument
The Four Corners Monument marks the quadripoint in the Southwestern United States where the U.S. state, states of Arizona, Colorado, New Mexico, and Utah meet. It is the only point in the United States shared by four states, leading to the area being named the Four Corners region. The monument also marks the boundary between two semi-autonomous Native Americans in the United States, Native American governments, the Navajo Nation, which maintains the monument as a tourist attraction, and the Ute Mountain Ute Tribe Reservation. The origins of the state boundaries marked by the monument occurred just prior to, and during, the American Civil War, when the United States Congress acted to form governments in the area to combat the spread of Slavery in the United States, slavery to the region. When the early territories were formed, their boundaries were designated along Geographic coordinate system, meridian and parallel lines. Beginning in the 1860s, these lines were surveyed and mar ...

Text File
A text file (sometimes spelled textfile; an old alternative name is flat file) is a kind of computer file that is structured as a sequence of lines of electronic text. A text file exists stored as data within a computer file system. In operating systems such as CP/M, where the operating system does not keep track of the file size in bytes, the end of a text file is denoted by placing one or more special characters, known as an end-of-file (EOF) marker, as padding after the last line in a text file. In modern operating systems such as DOS, Microsoft Windows and Unix-like systems, text files do not contain any special EOF character, because file systems on those operating systems keep track of the file size in bytes. Some operating systems, such as Multics, Unix-like systems, CP/M, DOS, the classic Mac OS, and Windows, store text files as a sequence of bytes, with an end-of-line delimiter at the end of each line. Other operating systems, such as OpenVMS and OS/360 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oil Exploration
Hydrocarbon exploration (or oil and gas exploration) is the search by petroleum geologists and geophysicists for hydrocarbon deposits, particularly petroleum and natural gas, in the Earth's crust using petroleum geology. Exploration methods Visible surface features such as oil seeps, natural gas seeps, pockmarks (underwater craters caused by escaping gas) provide basic evidence of hydrocarbon generation (be it shallow or deep in the Earth). However, most exploration depends on highly sophisticated technology to detect and determine the extent of these deposits using exploration geophysics. Areas thought to contain hydrocarbons are initially subjected to a gravity survey, magnetic survey, passive seismic or regional seismic reflection surveys to detect large-scale features of the sub-surface geology. Features of interest (known as ''leads'') are subjected to more detailed seismic surveys which work on the principle of the time it takes for reflected sound waves to travel t ...

Colorado Territory
The Territory of Colorado was an organized incorporated territory of the United States that existed from February 28, 1861, until August 1, 1876, when it was admitted to the Union as the 38th State of Colorado. The territory was organized in the wake of the Pike's Peak Gold Rush of 1858–1862, which brought the first large concentration of white settlement to the region. The organic legislative act creating the free Territory of Colorado was passed by the United States Congress and signed by 15th President James Buchanan into law on February 28, 1861. This was during the onset of the American Civil War of April 1861 to June 1865. The boundaries of the newly designated Colorado Territory were essentially identical with those of the modern State of Colorado, with lands taken from the four surrounding previous Federal territories of Nebraska, Kansas, New Mexico, and Utah established during the 1850s. The organization of the new territory helped solidify Union cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Mexico Territory
The Territory of New Mexico was an organized incorporated territory of the United States from September 9, 1850, until January 6, 1912. It was created from the U.S. provisional government of New Mexico, as a result of '' Nuevo México'' becoming part of the American frontier after the Treaty of Guadalupe Hidalgo. It existed with varying boundaries until the territory was admitted to the Union as the U.S. state of New Mexico in 1912. This jurisdiction was an organized, incorporated territory of the US for nearly 62 years, the longest period of any territory in the contiguous United States. Before the territory was organized In 1846, during the Mexican–American War, the United States established a provisional government of New Mexico. Territorial boundaries were somewhat ambiguous. After the Mexican Republic formally ceded the region to the United States in 1848, this temporary wartime/military government operated until September 9, 1850. Earlier in 1850, organizers pr ...

Arizona Territory
The Territory of Arizona, commonly known as the Arizona Territory, was a territory of the United States that existed from February 24, 1863, until February 14, 1912, when the remaining extent of the territory was admitted to the Union as the state of Arizona. It was created from the western half of the New Mexico Territory during the American Civil War. History Following the expansion of the New Mexico Territory in 1853, as a result of the Gadsden Purchase, several proposals for a division of the territory and the organization of a separate Territory of Arizona in the southern half of the territory were advanced as early as 1856. These proposals arose from concerns about the ability of the territorial government in Santa Fe to effectively administer the newly acquired southern portions of the territory. The first proposal dates from a conference held in Tucson that convened on August 29, 1856. The conference issued a petition to the U.S. Congress, signed by 256 people ...

Mexican–American War
The Mexican–American War (Spanish language, Spanish: ''guerra de Estados Unidos-México, guerra mexicano-estadounidense''), also known in the United States as the Mexican War, and in Mexico as the United States intervention in Mexico, (April 25, 1846 – February 2, 1848) was an invasion of Second Federal Republic of Mexico, Mexico by the United States Army. It followed the 1845 American annexation of Texas, which Mexico still considered its territory because it refused to recognize the Treaties of Velasco, signed by President Antonio López de Santa Anna after he was captured by the Texian Army during the 1836 Texas Revolution. The Republic of Texas was ''de facto'' an independent country, but most of its Anglo-American citizens who had moved from the United States to Texas after 1822 wanted to be annexed by the United States. Sectional politics over slavery in the United States had previously prevented annexation because Texas would have been admitted as a slave state ...
