Echo Park (Colorado)
Echo Park is a remote river bottom surrounded by canyon walls on the Green River, just downstream from the confluence with the Yampa River and across the stream from the dramatic southern end of Steamboat Rock in Dinosaur National Monument. Description The valley was first mapped and given its name by the Powell Geographic Expedition in 1869. A proposed dam at Echo Park turned into a nationwide environmental controversy in the early 1950s. The Sierra Club and other conservationist groups helped forge a compromise in Congress that eliminated the Echo Park Dam from the Colorado River Storage Project Act of 1956. See also * Dinosaur National Monument Dinosaur National Monument is an American national monument located on the southeast flank of the Uinta Mountains on the border between Colorado and Utah at the confluence of the Green and Yampa rivers.

Green River Steamboat Rock NPS1
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, while red was r ...

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] |
Yampa River
The Yampa River flows through northwestern Colorado in the United States. Rising in the Rocky Mountains, it is a tributary of the Green River (Colorado River), Green River and a major part of the Colorado River system. The Yampa is one of the few free-flowing rivers in the western United States, with only a few small dams and diversions. The name is derived from the Snake Indians word for the Perideridia plant, which has an edible root. John C. Frémont was among the first to record the name 'Yampah' in entries of hijournal from 1843 as he found the plant was particularly abundant in the watershed. Course The headwaters of the Yampa are in the Park Range (Colorado), Park Range in Routt County, Colorado as the confluence of the Bear River (Colorado), Bear River and Phillips Creek, near the town of Yampa, Colorado, Yampa. The Bear River, larger of the two, flows from a source of at Derby Peak in the Flat Tops Wilderness. The Yampa River then flows north through a high mountain v ...

Steamboat Rock (Dinosaur National Monument)
Steamboat Rock, reaching an elevation of 6,074 ft (1,851 m) is a promontory located in the eastern Uinta Mountains, in Moffat County of northwest Colorado, United States. This iconic landmark of Dinosaur National Monument is situated at the confluence of the Green River and Yampa River. Precipitation runoff from this feature drains into the Green River. This geographical formation was originally named "Echo Rock" in John Wesley Powell's 1875 report, '' The Exploration of the Colorado River and Its Canyons''. The Steamboat name first appeared on a 1941 United States Geological Survey map of Dinosaur National Monument. The area around it still retains the Echo Park name applied by Powell during the Powell Geographic Expedition of 1869. Geology Steamboat Rock is a mile-long, 1,000-ft high, slender peninsular ridge within a meander of the Green River. It is composed almost entirely of Permian- Pennsylvanian Weber Sandstone, with a thin layer of Park City Formation caprock. It is loc ...

Dinosaur National Monument
Dinosaur National Monument is an American national monument located on the southeast flank of the Uinta Mountains on the border between Colorado and Utah at the confluence of the Green and Yampa rivers. Although most of the monument area is in Moffat County, Colorado, the Dinosaur Quarry is located in Utah, north of the town of Jensen, Utah. The nearest Colorado town is Dinosaur while the nearest city is Vernal, Utah. Originally preserved in 1915 to protect its famous Dinosaur Quarry, the monument was greatly expanded in 1938 to include its wealth of natural history. The park's wild landscapes, topography, geology, paleontology, and history make it a unique resource for both science and recreation. The park contains over 800 paleontological sites and has fossils of dinosaurs including ''Allosaurus'', ''Deinonychus'', '' Abydosaurus'', and various sauropods. The ''Abydosaurus'' consists of a nearly complete skull, the lower jaw, and first four neck vertebrae. The specimen was fo ...

Powell Geographic Expedition
The Powell Geographic Expedition of 1869, led by American naturalist John Wesley Powell, was the first thorough cartographic and scientific investigation of long segments of the Green and Colorado rivers in the southwestern United States, including the first recorded passage of white men through the entirety of the Grand Canyon. The expedition, which lasted approximately three months during the summer of 1869, embarked from Green River Station, Wyoming Territory and traveled downstream through parts of the present-day states of Colorado and Utah before reaching the confluence of the Colorado and Virgin rivers in present-day Arizona and Nevada . Despite a series of hardships, including losses of boats and supplies, near-drownings, and the eventual departures of several crew members, the voyage produced the first detailed descriptions of much of the previously unexplored canyon country of the Colorado Plateau. Powell retraced part of the 1869 route on a second expedition in the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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. The club is known for its political endorsements, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Colorado River Storage Project
The Colorado River Storage Project is a United States Bureau of Reclamation project designed to oversee the development of the upper Colorado River basin. The project provides hydroelectric power, flood control and water storage for participating states along the upper portion of the Colorado River and its major tributaries. Since its inception in 1956, the project has grown to include the participation of several related water management projects throughout the river's basin. The project's original scope, and primary focus, are the upper Colorado River itself, the Green River, the San Juan River, and the Gunnison River. Participating states are Arizona, Utah, New Mexico, Colorado and Wyoming. History Attempts at managing the water supply in the upper Colorado River basin were first recorded in 1854 at Fort Supply in Wyoming, when water was diverted from Blacks Fork to irrigate local lands. Subsequent diversions of the waters in the Colorado basin led to preliminary investig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Colorado
The geography of the United States, U.S. Colorado, State of Colorado is diverse, encompassing both rugged mountainous terrain, vast plains, desert lands, desert canyons, and mesas. Colorado is a landlocked U.S. state. In 1861, the Thirty-sixth United States Congress, United States Congress defined the boundaries of the new Territory of Colorado exclusively by lines of latitude and longitude, stretching from 37th parallel north, 37°N to 41st parallel north, 41°N latitude, and from 25th meridian west from Washington, 102°02'48"W to 32nd meridian west from Washington, 109°02'48"W longitude (25th meridian west from Washington, 25°W to 32nd meridian west from Washington, 32°W from the Washington Meridian). Starting in 1868, official surveys demarcated the boundaries, deviating from the parallels and meridians in several places. Later surveys attempted to correct some of these mistakes but in 1925 the Supreme Court of the United States, U.S. Supreme Court affirmed that the ear ...

Geography Of Moffat County, Colorado
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
