Green River, Utah
Green River is a city in Emery County, Utah. The population was 847 at the 2020 census. History The city of Green River is located in ancestral Ute lands, in the home locale of the Seuvarits/Sheberetch band of Ute people. The Old Spanish Trail trade route passed across the Green River in the area of modern Green River from 1829 into the 1850s. John Wesley Powell embarked on the first of two voyages down the Green River in May 1869 and floated the river to its confluence with the Colorado and beyond. Powell left a detailed account of the river and the surrounding landscape and prepared the first thorough maps of the river basin. Powell left his mark in other ways as well. He and his men named most of the canyons, geographic features, and rapids along the Green River during his two voyages in 1869 and 1871. Powell also paved the way for later generations of explorers and scientists interested in the unique geology of the basin of the Green River. The settlement of the Green Riv ...

City
A city is a human settlement of notable size.Goodall, B. (1987) ''The Penguin Dictionary of Human Geography''. London: Penguin.Kuper, A. and Kuper, J., eds (1996) ''The Social Science Encyclopedia''. 2nd edition. London: Routledge. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution. Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for g ...

Old Spanish Trail (trade Route)
The Old Spanish Trail ( es, Viejo Sendero Español) is a historical trade route that connected the northern New Mexico settlements of (or near) Santa Fe, New Mexico with those of Los Angeles, California and southern California. Approximately long, the trail ran through areas of high mountains, arid deserts, and deep canyons. It is considered one of the most arduous of all trade routes ever established in the United States. Explored, in part, by Spanish explorers as early as the late 16th century, the trail was extensively used by traders with pack trains from about 1830 until the mid-1850s. The name of the trail comes from the publication of John C. Frémont’s Report of his 1844 journey for the U.S. Topographical Corps, guided by Kit Carson, from California to New Mexico. The name acknowledges the fact that parts of the trail had been known and used by the Spanish since the 16th century. Frémont's report identified a trail that had already been in use for about 15 years. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canyonlands National Park
Canyonlands National Park is an American national park located in southeastern Utah near the town of Moab. The park preserves a colorful landscape eroded into numerous canyons, mesas, and buttes by the Colorado River, the Green River, and their respective tributaries. Legislation creating the park was signed into law by President Lyndon Johnson on September 12, 1964. The park is divided into four districts: the Island in the Sky, the Needles, the Maze, and the combined rivers—the Green and Colorado—which carved two large canyons into the Colorado Plateau. While these areas share a primitive desert atmosphere, each retains its own character. Author Edward Abbey, a frequent visitor, described the Canyonlands as "the most weird, wonderful, magical place on earth—there is nothing else like it anywhere." History In the early 1950s, Bates Wilson, then superintendent of Arches National Monument, began exploring the area to the south and west of Moab, Utah. After seeing what is ...

San Rafael Swell
The San Rafael Swell is a large geologic feature located in south-central Utah, United States about west of Green River. The San Rafael Swell, measuring approximately , consists of a giant dome-shaped anticline of sandstone, shale, and limestone that was pushed up during the Paleocene Laramide Orogeny 60–40 million years ago. Since that time, infrequent but powerful flash floods have eroded the sedimentary rocks into numerous valleys, canyons, gorges, mesas, buttes, and badlands. The swell is part of the Colorado Plateau physiographic region. Geography Interstate 70 divides the Swell into northern and southern sections, and provides the only interstate access to the region. The swell lies entirely within Emery County. The northern Swell is drained mainly by the San Rafael River, while the southern Swell is drained mainly by Muddy Creek, which eventually joins the Fremont River to become Dirty Devil River northeast of Hanksville, Utah. The Dirty Devil River flows southward ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

White Sands Missile Range
White Sands Missile Range (WSMR) is a United States Army military testing area and firing range located in the US state of New Mexico. The range was originally established as the White Sands Proving Ground on 9July 1945. White Sands National Park is located within the range. Significant events *The first atomic bomb (code named Trinity) was test detonated at Trinity Site near the northern boundary of the range on 16 July 1945, seven days after the White Sands Proving Ground was established. *After the conclusion of World War II, 100 long-range German V-2 rockets that were captured by U.S. military troops were brought to WSMR. Of these, 67 were test-fired between 1946 and 1951 from the White Sands V-2 Launching Site. (This was followed by the testing of American rockets, which continues to this day, along with testing other technologies.) *NASA's Space Shuttle Columbia landed on the Northrop Strip at WSMR on 30 March 1982 as the conclusion to mission STS-3.

Green River Launch Complex
The Utah Launch Complex was a Cold War military subinstallation of White Sands Missile Range for USAF and US Army rocket launches. In addition to firing Pershing missiles, the complex launched Athena RTV missiles with subscale (test) warheads of the Advanced Ballistic Re-entry System to reentry speeds and impact at the New Mexico range. From 1964 to 1975 there were 244 Green River launches, including 141 Athena launches and 60 Pershing 1 and Pershing 1a launches to 281 kilometers altitude. " Utah State Route 19 runs through the Green River Launch Complex, which is south of the town and eponym of Green River." Facilities Originally , the installation had several separated areas: ;Cantonment area: The post area had the entrance, headquarters and other offices, a fire station, telephone exchange, housing, and maintenance facilities.

Lake Powell
Lake Powell is an artificial reservoir on the Colorado River in Utah and Arizona, United States. It is a major vacation destination visited by approximately two million people every year. It is the second largest artificial reservoir by maximum water capacity in the United States behind Lake Mead, storing of water when full. However, Lake Mead has fallen below Lake Powell in size several times during the 21st century in terms of volume of water, depth and surface area. Lake Powell was created by the flooding of Glen Canyon by the Glen Canyon Dam, which also led to the 1972 creation of Glen Canyon National Recreation Area, a popular summer destination of public land managed by the National Park Service. The reservoir is named for John Wesley Powell, a civil war veteran who explored the river via three wooden boats in 1869. It primarily lies in parts of Garfield, Kane, and San Juan counties in southern Utah, with a small portion in Coconino County in northern Arizona. The northe ...

Henry Mountains
The Henry Mountains is a mountain range located in the southeastern portion of the U.S. state of Utah that runs in a generally north-south direction, extending over a distance of about . They were named by Almon Thompson in honor of Joseph Henry, the first secretary of the Smithsonian Institution. The nearest town of any size is Hanksville, Utah, which is north of the mountains. The Henry Mountains were the last mountain range to be added to the map of the 48 contiguous U.S. states (1872), and before their official naming by Thompson were sometimes referred to as the "Unknown Mountains." In Navajo, the range is still referred to as ''Dził Bizhiʼ Ádiní'' ("mountain whose name is missing"). The great majority of the land within the Henry Mountains is owned by the U.S. Bureau of Land Management. A herd of 350 American Bison roams freely in the Henrys. Geography and geology The range is clustered into two main groups, with Highway 276 dividing the two portions. The northern ...

Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
