Echo Park Dam
Echo Park Dam was proposed in the 1950s by the U.S. Bureau of Reclamation as a central feature of the Colorado River Storage Project. Situated on the Green River, a major tributary of the Colorado River, the dam was proposed for the Echo Park district of Dinosaur National Monument, flooding much of the Green and Yampa river valleys in the monument. The dam was bitterly opposed by preservationists, who saw the encroachment of a dam into an existing national park as another Hetch Hetchy, to be opposed as an appropriation of protected lands for development purposes. The Echo Park project was abandoned in favor of Glen Canyon Dam on the main stem of the Colorado, in lands that were not at that time protected. This was eventually regarded as a strategic mistake by conservation organizations. Project history The Echo Park Dam project was first proposed in 1941. Dinosaur National Monument was, at the time of its designation in 1915, a small park unit focused on the dinosaur fossil beds di ...

Colorado
Colorado (, other variants) is a state in the Mountain West subregion of the Western United States. It encompasses most of the Southern Rocky Mountains, as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is the eighth most extensive and 21st most populous U.S. state. The 2020 United States census enumerated the population of Colorado at 5,773,714, an increase of 14.80% since the 2010 United States census. The region has been inhabited by Native Americans and their ancestors for at least 13,500 years and possibly much longer. The eastern edge of the Rocky Mountains was a major migration route for early peoples who spread throughout the Americas. "''Colorado''" is the Spanish adjective meaning "ruddy", the color of the Fountain Formation outcroppings found up and down the Front Range of the Rocky Mountains. The Territory of Colorado was organized on February 28, 1861, and on August 1, 1876, U.S. President Ulyss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Whirlpool Canyon
A whirlpool is a body of rotating water produced by opposing currents or a current running into an obstacle. Small whirlpools form when a bath or a sink is draining. More powerful ones formed in seas or oceans may be called maelstroms ( ). ''Vortex'' is the proper term for a whirlpool that has a downdraft. In narrow ocean straits with fast flowing water, whirlpools are often caused by tides. Many stories tell of ships being sucked into a maelstrom, although only smaller craft are actually in danger. Smaller whirlpools appear at river rapids and can be observed downstream of artificial structures such as weirs and dams. Large cataracts, such as Niagara Falls, produce strong whirlpools. Notable whirlpools Saltstraumen Saltstraumen is a narrow strait located close to the Arctic Circle, south-east of the city of Bodø, Norway. It has one of the strongest tidal currents in the world. Whirlpools up to in diameter and in depth are formed when the current is at its strongest. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utah
Utah ( , ) is a state in the Mountain West subregion of the Western United States. Utah is a landlocked U.S. state bordered to its east by Colorado, to its northeast by Wyoming, to its north by Idaho, to its south by Arizona, and to its west by Nevada. Utah also touches a corner of New Mexico in the southeast. Of the fifty U.S. states, Utah is the 13th-largest by area; with a population over three million, it is the 30th-most-populous and 11th-least-densely populated. Urban development is mostly concentrated in two areas: the Wasatch Front in the north-central part of the state, which is home to roughly two-thirds of the population and includes the capital city, Salt Lake City; and Washington County in the southwest, with more than 180,000 residents. Most of the western half of Utah lies in the Great Basin. Utah has been inhabited for thousands of years by various indigenous groups such as the ancient Puebloans, Navajo and Ute.

Browns Park
Brown's Park or Browns Park, originally called Brown's Hole, is an isolated mountain valley along the Green River in Moffat County, Colorado and Daggett County, Utah in the United States. The valley begins in far eastern Utah, approximately downstream from Flaming Gorge Dam, and follows the river downstream into Colorado, ending at the Gates of Lodore in Dinosaur National Monument. Known as a haven for outlaws such as Butch Cassidy and Tom Horn during the late 19th century and the early 20th century, it is now the location of the Browns Park National Wildlife Refuge. It was also the birthplace of Ann Bassett. She and her sister Josie Bassett, were considered female outlaws and girlfriends to several of Cassidy's Wild Bunch gang. It is the location of John Jarvie Historic Ranch, where, in 1880, Scotsman John Jarvie built a ranch along the Green River. History According to Robert Redford, The earliest-known reference to Brown's Park was made in 1650 in the writings of Father Or ...

Gravity Dam
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...

Sierra Club
The Sierra Club is an environmental organization with chapters in all 50 United States, Washington D.C., and Puerto Rico. The club was founded on May 28, 1892, in San Francisco, California, by Scottish-American preservationist John Muir, who became the first president as well as the longest-serving president, at approximately 20 years in this leadership position. The Sierra Club operates only in the United States and holds the legal status of 501(c)(4) nonprofit social welfare organization. Sierra Club Canada is a separate entity. Traditionally associated with the progressive movement, the club was one of the first large-scale environmental preservation organizations in the world, and currently engages in lobbying politicians to promote environmentalist policies. Recent focuses of the club include promoting sustainable energy and mitigating global warming, as well as opposition to the use of coal, hydropower and nuclear power.

Monument Valley
Monument Valley ( nv, Tsé Biiʼ Ndzisgaii, , meaning ''valley of the rocks'') is a region of the Colorado Plateau characterized by a cluster of sandstone buttes, the largest reaching above the valley floor. It is located on the Utah-Arizona state line, near the Four Corners area. The valley is a sacred area that lies within the territory of the Navajo Nation Reservation, the Native American people of the area. Monument Valley has been featured in many forms of media since the 1930s. Director John Ford used the location for a number of his Westerns; critic Keith Phipps wrote that "its have defined what decades of moviegoers think of when they imagine the American West." Geography and geology The area is part of the Colorado Plateau. The elevation of the valley floor ranges from above sea level. The floor is largely siltstone of the Cutler Group, or sand derived from it, deposited by the meandering rivers that carved the valley. The valley's vivid red color comes from iron ...

Yellowstone National Park
Yellowstone National Park is an American national park located in the western United States, largely in the northwest corner of Wyoming and extending into Montana and Idaho. It was established by the 42nd U.S. Congress with the Yellowstone National Park Protection Act and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially the Old Faithful geyser, one of its most popular. While it represents many types of biomes, the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion. While Native Americans have lived in the Yellowstone region for at least 11,000 years, aside from visits by mountain men during the early-to-mid-19th century, organized exploration did not begin until the late 1860s. Management and control of the park ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Escalante National Monument
Escalante National Monument was proposed by Secretary of the Interior Harold Ickes in the 1930s as a unit of the U.S. National Park Service in the canyonlands of south central Utah. Centering on the canyons of the Escalante River, the proposed monument encompassed portions of present-day Canyonlands and Capitol Reef national parks, Natural Bridges and Grand Staircase-Escalante national monuments and Glen Canyon National Recreation Area. The proposed national monument was to encompass about . The Second World War interrupted Ickes initiative, which had encountered resistance from Utah politicians. The scheme was partially fulfilled with the establishment of Capitol Reef National Monument under the Antiquities Act in 1937 and Canyonlands National Park by act of Congress in 1964, and expanded with the proclamation of the Grand Staircase-Escalante National Monument by the Clinton Administration in 1996. Later proposals by the National Parks Conservation Association in the 1980s, for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
