Expedition Island
Expedition Island is an island in the Green River (Colorado River), Green River at downtown Green River, Wyoming. The island, now mostly taken up by a public park, is the place where Major John Wesley Powell and Vitaly Develvis started an expedition down the Green River (Colorado River), Green River and Colorado River in 1871. The park is also believed to mark where Major Powell started his earlier expedition down the two rivers in 1869. Expedition Island was designated a National Historic Landmark for this historic association on November 24, 1968. and Description and history Expedition Island is located in the Green River, which flows roughly east–west south of downtown Green River. The island was originally larger, having been divided into two by subsequent erosive river actions. The northern island is undeveloped and overgrown, and is not believed to be the site of historic activity. The southern island is now a public park, with a recreation center and parking ar ...

Green River (Colorado River)
The Green River, located in the western United States, is the chief tributary of the Colorado River. The watershed of the river, known as the Green River Basin, covers parts of the U.S. states of Wyoming, Utah, and Colorado. The Green River is long, beginning in the Wind River Mountains of Wyoming and flowing through Wyoming and Utah for most of its course, except for a short segment of in western Colorado. Much of the route traverses the arid Colorado Plateau, where the river has carved some of the most spectacular canyons in the United States. The Green is slightly smaller than Colorado when the two rivers merge but typically carries a larger load of silt. The average yearly mean flow of the river at Green River, Utah is per second. The status of the Green River as a tributary of the Colorado River came about mainly for political reasons. In earlier nomenclature, the Colorado River began at its confluence with the Green River. Above the confluence, Colorado was called the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green River, Wyoming
Green River is a city in and the county seat of Sweetwater County, Wyoming, United States, in the southwestern part of the state. The population was 12,515 at the 2010 census. History The townsite of Green River, Dakota Territory was platted by the Union Pacific Railroad in 1867. Although the Territory of Wyoming was created on July 25, 1868, the Town of Green River was incorporated on August 21,1868 under the laws of the previous Territory of Dakota since the laws of the Wyoming Territory had yet to be written. The Town of Green River was re-incorporated on June 10, 1891 under the laws of the State of Wyoming to remove any ambiguity. The Union Pacific Railroad reached Green River on October 1, 1868 and was supposed to be the site of a division point for the railroad. Railroad officials were surprised to find that a town of 2000 residents and permanent adobe buildings had been established there, likely requiring costly negotiations for railroad land. They moved th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Wesley Powell
John Wesley Powell (March 24, 1834 – September 23, 1902) was an American geologist, U.S. Army soldier, explorer of the American West, professor at Illinois Wesleyan University, and director of major scientific and cultural institutions. He is famous for his 1869 geographic expedition, a three-month river trip down the Green and Colorado rivers, including the first official U.S. government-sponsored passage through the Grand Canyon. Powell was appointed by US President James A. Garfield to serve as the second director of the U.S. Geological Survey (1881–1894) and proposed, for development of the arid West, policies that were prescient for his accurate evaluation of conditions. Two years prior to his service as director of the U.S. Geological Survey, Major Powell had become the first director of the Bureau of Ethnology at the Smithsonian Institution where he supported linguistic and sociological research and publications.

Colorado River
The Colorado River ( es, Río Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern Mexico. The river drains an expansive, arid drainage basin, watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the Mexico–United States border, international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora. Known for its dramatic canyons, whitewater rapids, and eleven National parks of the United States, U.S. National Parks, the Colorado River and its tributaries are a v ...

National Historic Landmark
A National Historic Landmark (NHL) is a building, district, object, site, or structure that is officially recognized by the United States government for its outstanding historical significance. Only some 2,500 (~3%) of over 90,000 places listed on the country's National Register of Historic Places are recognized as National Historic Landmarks. A National Historic Landmark District may include contributing properties that are buildings, structures, sites or objects, and it may include non-contributing properties. Contributing properties may or may not also be separately listed. Creation of the program Prior to 1935, efforts to preserve cultural heritage of national importance were made by piecemeal efforts of the United States Congress. In 1935, Congress passed the Historic Sites Act, which authorized the Interior Secretary authority to formally record and organize historic properties, and to designate properties as having "national historical significance", and gave the Nation ...

Kibibyte
The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as The Internet Protocol () refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The first bit is number 0, making the eighth bit number 7. The size of the byte has historically been hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six-bit character code was an often-used implementation in early encoding systems, and computers using six-bit and nine-bit bytes were common in the 1960s. These systems often had memory words ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Canyon
The Grand Canyon (, yuf-x-yav, Wi:kaʼi:la, , Southern Paiute language: Paxa’uipi, ) is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is long, up to wide and attains a depth of over a mile (). The canyon and adjacent rim are contained within Grand Canyon National Park, the Kaibab National Forest, Grand Canyon–Parashant National Monument, the Hualapai Indian Reservation, the Havasupai Indian Reservation and the Navajo Nation. President Theodore Roosevelt was a major proponent of the preservation of the Grand Canyon area and visited it on numerous occasions to hunt and enjoy the scenery. Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted.

Continental United States
The contiguous United States (officially the conterminous United States) consists of the 48 adjoining U.S. states and the Federal District of the United States of America. The term excludes the only two non-contiguous states, Alaska and Hawaii (also the last ones admitted to the Union), and all other offshore insular areas, such as American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands. The colloquial term "Lower48" is used also, especially in relation to just Alaska (Hawaii is farther south). The related but distinct term continental United States includes Alaska (which is also on the continent of North America but separated from the 48 states by British Columbia and Yukon of Canada), but excludes the Hawaiian Islands and all U.S. territories in the Caribbean and the Pacific. The greatest distance (on a great-circle route) entirely within the contiguous U.S. is 2,802 miles (4,509 km), between Florida and the State of Washington; th ...

European-American
European Americans (also referred to as Euro-Americans) are Americans of European ancestry. This term includes people who are descended from the first European settlers in the United States as well as people who are descended from more recent European arrivals. European Americans have been the largest panethnic group in the United States since about the 17th century. The Spaniards are thought to be the first Europeans to establish a continuous presence in what is now the contiguous United States, with Martín de Argüelles ( 1566) in St. Augustine, then a part of Spanish Florida, and the Russians were the first Europeans to settle in Alaska, establishing Russian America. The first English child born in the Americas was Virginia Dare, born August 18, 1587. She was born in Roanoke Colony, located in present-day North Carolina, which was the first attempt, made by Queen Elizabeth I, to establish a permanent English settlement in North America. In the 2016 American Communit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wyoming Territory
The Territory of Wyoming was an organized incorporated territory of the United States that existed from July 25, 1868, until July 10, 1890, when it was admitted to the Union as the State of Wyoming. Cheyenne was the territorial capital. The boundaries of the Wyoming Territory were identical to those of the modern State of Wyoming. Background Because of Wyoming's location as part of the Louisiana Purchase, the Oregon Country, and the Mexican Cession, the land which became Wyoming has a complicated history of territorial relationships. Portions of the territory, which eventually fell under Wyoming's jurisdiction, were at various points associated with the territories of Washington, Oregon, Idaho, Dakota, Nebraska, and Utah, and had previously belonged to the independent states of Great Britain, France, Spain, Mexico, and Texas. The portion of the Wyoming Territory east of the continental divide was acquired by the U.S. in the 1803 Louisiana Purchase and organized into the Nebras ...
