The '''Green River''', located in the western United States, is the chief [[Earth:Tributary|tributary]] of the [[Earth:Colorado River|Colorado River]]. The [[Earth:Drainage basin|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 {{convert|730|mi|km}} 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 {{convert|40|mi|km}} in western Colorado. Much of the route traverses the arid [[Earth:Colorado Plateau|Colorado Plateau]], where the river has carved some of the most spectacular [[Earth:Canyon|canyon]]s in the United States. The Green is slightly smaller than Colorado when the two rivers merge but typically carries a larger load of [[Earth:Silt|silt]]. The average yearly mean flow of the river at Green River, Utah is {{convert|6121|cuft|m3}} per second.<ref name="enright" />

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 Grand River. In 1921, U.S. Representative Edward T. Taylor of Colorado petitioned the Congressional Committee on Interstate and Foreign Commerce to rename the Grand River as the Colorado River. On July 25, 1921, the name change was made official in House Joint Resolution 460 of the 66th Congress, over the objections of representatives from Wyoming and Utah and the United States Geological Survey, which noted that the drainage basin of the Green River was more extensive than that of the Grand River,<ref>[http://www.summitdaily.com/article/20031223/OPINION/312230302 Many years ago, the Colorado River was just Grand], retrieved January 5, 2008.</ref> although the Grand carried a higher volume of water at its confluence with the Green.

The headwaters of the Green River is in western Wyoming, in northern Sublette County, on the western side of the Continental Divide in the Wind River Range and the Bridger–Teton National Forest. It flows south through Sublette County and western Wyoming in an area known as the Upper Green River Valley, then southwest and is joined by the Big Sandy River in western Sweetwater County. At the town of La Barge, it flows into Fontenelle Reservoir, formed by Fontenelle Dam. Below the dam, it flows through open sage-covered rolling prairie where it is crossed by the Oregon, California and Mormon emigration trails, and then further south past the town of Green River, Wyoming and into the Flaming Gorge Reservoir in southwestern Wyoming, formed by the Flaming Gorge Dam in northeastern Utah. Before the reservoir's creation, the Blacks Fork joined the Green River south of the town of Green River, but today the mouth of Blacks Fork is submerged by the reservoir.

South of the dam, it is forced to turn sharply eastward by the uplift of the [[Earth:Uinta Mountains|Uinta Mountains]], looping around the eastern tip of the range as it travels from Utah into northwestern Colorado and through Browns Park before turning west and then south into [[Earth:Dinosaur National Monument|Dinosaur National Monument]], where it passes through the Canyon of the Lodore (otherwise known as the Gates of Lodore) and is joined by the Yampa River at [[Earth:Steamboat Rock (Dinosaur National Monument)|Steamboat Rock]]. It turns westward back into Utah along the southern edge of the Uintas in Whirlpool Canyon. In Utah, it meanders southwest across the Yampa Plateau and through the Uintah and Ouray Indian Reservation and the Ouray National Wildlife Refuge. Two miles south of Ouray, Utah, it is joined by the Duchesne River, and three miles (5&nbsp;km) farther downstream by the White River. Ten miles farther downstream, it is joined by the Willow River.

South of the plateau, it is joined by Nine Mile Creek, then enters the [[Earth:Roan Cliffs|Roan Cliffs]] where it flows south through the back-to-back Desolation and Gray canyons, with a combined length of 120&nbsp;mi (192&nbsp;km). In Gray Canyon, it is joined by the Price River. South of the canyon, it passes the town of Green River, Utah and is joined by the San Rafael River in southern Emery County. In eastern Wayne County it meanders through [[Earth:Canyonlands National Park|Canyonlands National Park]], where it joins Colorado.<ref>[https://pubs.usgs.gov/bul/1291/report.pdf GEOLOGIC STORY of UINTA MOUNTAINS] By  Wallace R.

The Flaming Gorge Dam in Utah is a significant regional source of water for irrigation and mining, as well as for hydroelectric power. Begun in the 1950s and finished in 1963, it was highly controversial and opposed by conservationists.  Originally, a dam was to be built in Whirlpool Canyon, but the conservationist movement traded the Flaming Gorge Dam for halting that proposal.

The Green is a large, deep, powerful river. It ranges from 100 to 300 feet (30 to 100 m) wide in the upper course and from {{convert|300|to|1500|ft|m}} wide in its lower course, and from {{convert|3|to|50|ft|m}} in depth. It is navigable by small craft throughout its course and by large motorboats upstream to Flaming Gorge Dam. Near the areas where the Oregon Trail crosses the river, it is {{convert|400|to|500|ft|m}} wide and averages about {{convert|20|ft|m}} deep at normal flow.

[[Earth:Archaeology|Archaeological]] evidence indicates that the tributary canyons and sheltered areas in the river valley were home to the Fremont Culture, which flourished from the 7th century to the 13th century. The Fremont were semi-nomadic people who lived in pithouses and are best known for the rock art on canyon walls and in sheltered overhangs.

In later centuries, the river basin was home to the Shoshone and Ute peoples, both nomadic hunters. The Shoshone inhabited the river valley north of the [[Earth:Uinta Mountains|Uinta Mountains]], whereas the Utes lived to the south. The current reservation of the Utes is in the [[Earth:Uintah Basin|Uintah Basin]]. The Shoshone called the river the ''Seeds-kee-dee-Agie'', meaning "Prairie Hen River."

In 1776, the Spanish friars Silvestre Vélez de Escalante and Francisco Atanasio Domínguez crossed the river near present-day Jensen, naming it the Rio de San Buenaventura. The map-maker of the expedition, Captain Bernardo Miera y Pacheco, erroneously indicated that the river flowed southwest to what is now known as Sevier Lake. Later cartographers extended the error, representing the Buenaventura River as flowing into the [[Earth:Pacific Ocean|Pacific Ocean]]. At least one charted the Buenaventura as draining the Great Salt Lake. Later, Spanish and Mexican explorers adopted the name Rio Verde, meaning "Green River" in [[Social:Spanish language|Spanish]]. Exactly when the Spanish started using this name and why is unknown. Explanations of the name "Green" include ideas about the color of the water (though it is usually just as red as that of the Colorado), the color of soapstone along its banks, the color of the vegetation, and the name of a trapper. No explanation can be verified.[http://historytogo.utah.gov/utah_chapters/the_land/greenriver.html] {{Webarchive|url=https://web.archive.org/web/20110628200404/http://historytogo.utah.gov/utah_chapters/the_land/greenriver.html |date=2011-06-28 }} Wilson Hunt of John Jacob Astor's Pacific Fur Company called it The Spanish River in 1811.<ref>{{cite web|url=http://www.waymarking.com/waymarks/WM18ZM|title=Seeds-Kee-Dee-Agie - Wyoming Historical Markers on Waymarking.com|website=www.waymarking.com|access-date=27 January 2018}}</ref> By that time it was clear to the trappers that Miera's map<ref name=miera>An image of Miera's map is viewable at the Wikipedia site for Buenaventura River (legend)</ref> (if they had seen it) was wrong, for they had learned from the Native Americans that the Green River drained to the Colorado River and the Gulf of California. When Jedediah Smith reached the lower Colorado in 1826, he first called it the Seedskeedee, as the Green/Colorado River was commonly known among the trappers. By the time of Bonneville's expedition in 1832, the names "Seeds-kee-dee", "Spanish River", "Green River", and even "Colorado River" were used interchangeably by the trappers and American explorers.<ref>{{cite web |url=http://www-lib.uwyo.edu/temp/wyshs/WT-HS-PR-AN17n2.htm |access-date=2008-11-04 |title=University of Wyoming }}</ref>

While it was known that the Green River drained to Colorado, the exact course was not known. Miera's map showed the Colorado River branching into two major streams – the Nabajoo (San Juan) and the Zaguananas. It also showed the Zaguananas branching into four heads, including the Dolores and the Rafael (the latter of which Escalante's journal equates with Colorado per information from the Native Americans).<ref>[http://www.mith2.umd.edu/eada/gateway/diario/diary.html Escalante's Journal] {{webarchive|url=https://web.archive.org/web/20110928071254/http://www.mith2.umd.edu/eada/gateway/diario/diary.html |date=2011-09-28 }} September 5</ref> A map of 1847 redirects the course of the Rafael to the north and labels it as Green River.<ref>{{cite web|url=http://hdl.loc.gov/loc.gmd/g4410.ct000127|title=Mapa de los Estados Unidos de Méjico : segun lo organizado y definido por las varias actas del congreso de dicha républica y construido por las mejores autoridades.|access-date=27 January 2018}}</ref> It would be some time before the true confluence of the Green and Colorado Rivers would be known.

The [[Earth:Old Spanish Trail (trade route)|Old Spanish Trail]] from New Mexico to {{wipe|California}} crossed the river just above the present-day town of Green River, Utah.

In the early 19th century, the upper river in Wyoming was part of the disputed Oregon Country. It was explored by trappers from the North West Company and Hudson's Bay Company, such as Donald Mackenzie who pioneered the area from 1819. In 1825, the American William Ashley and a party of American explorers floated down the river from north of the Uintah Mountains to the mouth of the White River. The valley of the river became increasingly used as a wintering ground for American trappers in the next decades, with trading posts established at the mouth of the White near Whiterocks, Utah, and Browns Park. The Upper Green River Rendezvous Site near Pinedale, Wyoming was a popular location for annual [[Social:Mountain man|mountain man]] rendezvous during the 1820s and 1830s, with as many as 450 to 500 trappers attending during its heyday in the 1830s.

The region was explored by John C. Fremont on several of his expeditions in the 1840s. Fremont corrected the cartographic error of Miera, establishing firmly that the river did not drain the Great Salt Lake. In 1869, the river was surveyed and mapped by John Wesley Powell as part of the first of his two expeditions to the region.  During his two voyages in 1869 and 1871, he and his men gave most of the current names of the canyons, geographic features, and rapids along the river. For example, "we sweep around another great bend to the left, making a circuit of nine miles, and come back to a point within 600 feet of the beginning of the bend. In the two circuits, we describe almost in figure 8. The men call it a `bowknot' of a river; so we name it '''Bowknot Bend'''." (Powell, 1869)

From the 1840s through the 1860s, hundreds of thousands of emigrants made their way west along the Oregon, California, and Mormon emigration trails.  Nearly all primary emigration routes had to cross the Green River.  The main trail crossed near where the Big Sandy River joins the Green River in Wyoming.  The river is too big and much too deep to ford at any time of the year and is the largest, most dangerous river crossed by the Oregon Trail. For that reason, ferries were commonly run on this stretch of the river. Some popular ferries included the Lombard and Robinson ferries at the main crossing and the Mormon, Mountain Man, and Names Hill ferries where the popular Sublette-Greenwood cutoff crossed the river further upstream.

In 1878 the first permanent settlement in the river valley was founded at Vernal  by a party of [[Religion:Mormonism|Mormons]] led by Jeremiah Hatch. The settlement survived a [[Medicine:Diphtheria|diphtheria]] epidemic its first winter, as well as a panic caused by the Meeker Massacre in Colorado.

Most of the land in the valley of the river today is owned and controlled by the federal government. Private holdings are largely limited to bottoms. Until the 1940s, the valley's economy was based largely on ranching.  Tourism has emerged as the dominant industry in the region in the last several decades.

A proposed nuclear power plant, the Blue Castle Project, is set to begin construction near Green River in 2023.<ref name="emery county progress 20170124">{{cite web |url=http://www.ecprogress.com/index.php?tier=1&article_id=19985 |title=Update on the Nuclear Power Plant for Green River |first=Patsy |last=Stoddard |date=January 24, 2017 |publisher=Emery County Progress |location=Castle Dale, Utah |access-date=February 9, 2017 |archive-date=February 11, 2017 |archive-url=https://web.archive.org/web/20170211075715/http://www.ecprogress.com/index.php?tier=1&article_id=19985 |url-status=dead }}</ref> The plant will use {{convert|53500|acre-ft}} of water annually from the Green River once both reactors are commissioned.

The La Barge oil field was discovered in 1924.  Oil was produced from [[Earth:Tertiary|Tertiary]] [[Earth:Sandstone|sandstone]]s ([[Earth:Wasatch Formation|Wasatch Formation]] and [[Earth:Green River Formation|Green River Formation]]), within an [[Earth:Anticline|anticline]] 600 to 1200 feet deep.  The Big Piney-La Barge complex has produced gas since 1956 and oil since 1960.  Cumulative production by 1976 was 65 million bbl of oil and over 1.2 Tcf (trillion cubic feet) of gas.

The discovery of [[Chemistry:Petroleum|petroleum]] at the Ashley Field after [[Social:World War II|World War II]] has led to the exploitation of oil and [[Chemistry:Natural gas|natural gas]] in the region.

The Green River Basin contains the world's largest known deposit of [[Chemistry:Trona|trona]] ore near Green River, Wyoming. Soda ash mining from trona veins 900 and 1600 feet (300 and 500 m) deep is a major industrial activity in the area, employing over 2000 persons at four mines. The mining operation is less expensive for the production of soda ash in the United States than the synthetic [[Chemistry:Solvay process|Solvay process]], which predominates in the rest of the world.{{cn|date=January 2023}}

The area has been mined for [[Chemistry:Uranium|uranium]].{{cn|date=January 2023}}
