The Uinta Basin (also known as the Uintah Basin) —a tributary of the Colorado River. The Uinta Mountains forms the northern border of the Uinta Basin. They contain the highest point in Utah, Kings Peak, with a summit 13,528 feet (4123 metres) above sea level. The climate of the Uinta Basin is semi-arid, with occasionally severe winter cold.is a physiographic section of the larger Colorado Plateaus province, which in turn is part of the larger Intermontane Plateaus physiographic division. It is also a geologic structural basin in eastern Utah, east of the Wasatch Mountains and south of the Uinta Mountains. The Uinta Basin is fed by creeks and rivers flowing south from the Uinta Mountains. Many of the principal rivers (Strawberry River, Currant Creek, Rock Creek, Lake Fork River, and Uintah River) flow into the Duchesne River which feeds the Green River
Father Escalante's expedition visited the Uinta Basin in September 1776. 1822–1840 French Canadian trappers Étienne Provost, François le Clerc, and Antoine Robidoux entered the Uinta Basin by way of the Old Spanish Trail and made their fortunes by trapping the many beaver and trading with the Uintah tribe. The Northern Ute Indian Reservation was established in 1861 by presidential decree. The United States opened the reservation for homesteading by non-Native Americans in 1905. During the early decades of the twentieth century, both Native and non-Native irrigation systems were constructed—the Uinta Indian Irrigation Project, the Moon Lake Project, and the Central Utah Project.
The largest community in the Utah part of the Uinta Basin is Vernal. According to the U.S. Census, the community's population in 2010 was 9,089. Other communities in the Utah part of the region include Duchesne, Roosevelt, Altamont, Tabiona, and a number of small unincorporated communities. The Uinta Basin is also the location of the Uintah and Ouray Indian Reservation, home to the Ute Tribe of the Uintah and Ouray Agency (also known as the Northern Ute Tribe). The Ute Tribe is the source of Utah's state name.
Local attractions include Dinosaur National Monument, Starvation Reservoir State Park, Flaming Gorge National Recreation Area, Raven Ridge and Fantasy Canyon.
The local economy, once based on agriculture and mining, has diversified, and energy extraction and tourism are now major industries as well. In order to move oil out of the region, a new railroad is proposed to be constructed into the basin. In addition, Utah State University operates Branch campuses at Vernal and Roosevelt, expanding educational opportunities in a previously underserved region of Utah.
The Uinta Basin is the most northerly section of the Colorado Plateau sections. The basin is 5,000 to 10,000 feet (1,500 to 3,000 m) above sea level and corresponding to this depression is a broad east-west strip of higher plateau that rises sharply above the denuded country to the south. On the south side of the plateau the descent of 3,000 feet (910 m), to the general level of eastern Utah on the south, is made in two steps. The first is the Roan Cliffs and the second, the Book Cliffs. Eastward in Colorado the two lines of cliffs are poorly distinguished. The Green River flows southward out of the Uinta Mountains to the north, crossing the Uinta Basin, and flows in a 5,000 feet (1,500 m) deep gorge known as Desolation Canyon. The Colorado River crosses the eastern portion of this section, cutting off an area of some 40 miles (64 kilometres) in diameter in which are preserved fragments of a lofty lava cap forming Grand Mesa and Battlement Mesa.
The Uinta Basin forms a geologic structural basin, and is the source of commercial oil and gas production. Separated from the Piceance Basin by the Douglas Creek Arch, both basins formed during the Laramide Orogeny, and are bounded by the Charleston-Nebo thrust fault, the Uinta Basin boundary fault, and the Grand Hogback monocline. The Uinta Basin includes the Wasatch Plateau. According to the USGS Uinta-Piceance Assessment Team, "The black-shale facies of the Green River Formation is the main petroleum system of Tertiary age whereas the Mahogany zone of the Green River Formation is a minor component. The Cretaceous Mancos Group and equivalent rocks are the main source of Cretaceous oil and a major contributor of gas in the basin, whereas the Upper Cretaceous Mesaverde is a lesser contributor of oil but a significant source for gas. Ferron Sandstone coals are known to be a source of coalbed methane. The most prominent source of oil from Paleozoic rocks is the Permian Phosphoria Formation.
During the Laramide Orogeny along the Wasatch Mountains, the north-south trending coast during the Late Cretaceous was receding eastward, at the same time the area where the basin is located was subsiding, creating a lacustrine environment. A clastic wedge consisting of the North Horn, Colton, and Wasatch was deposited northwards. These sediments interfingered with organic-rich lacustrine clays and carbonate muds of the Green River and Flagstaff facies. Later, deposits originated from the Uinta Mountains from the north, forming a southward-thinning clastic wedge. A carbonate sediment consisting of an organic-rich oil shale was deposited from the middle Eocene into the Oligocene. The basin is also known for solid-hydrocarbon-filled fractures consisting of ozocerite, gilsonite, and wurtzilite.
In 1948, oil was discovered in the Paleozoic portion of the basin at Ashley Valley. Tertiary discoveries followed in 1948 at Roosevelt, and then the Red Wash Field and Duchesne Field in 1951. The Bluebell Field was discovered in 1967 and the Altamont Field in 1970. The Altamont-Bluebell structural trap occurs where the Wasatch sandstone pinches out.

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 Wyoming, Utah, and Colorado. The Green River is 730 miles (1,170 km) long, beginning in the Wind River Mountains of Wyoming and flowing through Wyoming and Utah for most of its course, except for 40 miles (64 km) into western Colorado. Much of the route is through the Colorado Plateau and through some of the most spectacular canyons in the United States. It is only slightly smaller than the 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 6,121 cubic feet (173.3 m3) per second.
The Colorado Plateau, also known as the Colorado Plateau Province, is a physiographic and desert region of the Intermontane Plateaus, roughly centered on the Four Corners region of the southwestern United States. This province covers an area of 336,700 km2 (130,000 mi2) within western Colorado, northwestern New Mexico, southern and eastern Utah, northern Arizona, and a tiny fraction in the extreme southeast of Nevada. About 90% of the area is drained by the Colorado River and its main tributaries: the Green, San Juan, and Little Colorado. Most of the remainder of the plateau is drained by the Rio Grande and its tributaries.
Ute are the indigenous people of the Ute tribe and culture among the Indigenous peoples of the Great Basin. They have lived in the regions of present-day Utah and Colorado in the Southwestern United States for many centuries. The state of Utah is named after the Ute tribe.
The Uintah and Ouray Indian Reservation is located in northeastern Utah, United States. It is the homeland of the Ute Indian Tribe, and is the largest of three Indian reservations inhabited by members of the Ute Tribe of Native Americans.
The Ute Indian Tribe of the Uinta and Ouray Reservation is a Federally Recognized Tribe of Indians in northeastern Utah, United States. Three bands of Utes comprise the Ute Indian Tribe: the Whiteriver Band, the Uncompahgre Band and the Uintah Band. The Tribe has a membership of more than three thousand individuals, with over half living on the Uintah and Ouray Indian Reservation. The Ute Indian Tribe operates its own tribal government and oversees approximately 1.3 million acres of trust land which contains significant oil and gas deposits.
The Piceance Basin is a geologic structural basin in northwestern Colorado, in the United States. It includes geologic formations from Cambrian to Holocene in age, but the thickest section is made up of rocks from the Cretaceous Period. The basin contains reserves of coal, natural gas, and oil shale. The name likely derives from the Shoshoni word /piasonittsi/ meaning “tall grass”.
The Central Utah Project is a US federal water project that was authorized for construction under the Colorado River Storage Project Act of April 11, 1956, as a participating project. In general, the Central Utah Project develops a portion of Utah's share of the yield of the Colorado River, as set out in the Colorado River Compact of 1922.
The Northern Ute Tribe is one of three ethnically-related Ute Tribes. The Northern Ute Tribe occupies and administers the Uintah and Ouray Indian Reservation in northeastern Utah. The population of the Northern Ute Tribe is approximately 3,500.
In Section 203(a) of the Central Utah Project Completion Act, the United States Congress authorized a federally authorized and funded replacement project to replace the Uinta and Upalco Units of the Central Utah Project (CUP) which were not constructed. The replacement project is the Uinta Basin Replacement Project (UBRP). The UBRP will provide: 2,500 acre feet (3,100,000 m3) of irrigation water; 3,000 acre feet (3,700,000 m3) of municipal and industrial water; reduced wilderness impacts; increased instream flows; and improved recreation. Design work began in 2002. Construction began in 2004 and is anticipated to be completed in 2011. The Central Utah Water Conservancy District is responsible for construction. The United States Department of the Interior oversees funding and compliance with law and environmental regulation.
The Duchesne River, located in the Uintah Basin region of Utah in the western United States, is a tributary of the Green River. The watershed of the river covers the Northeastern corner of Utah. The Duchesne River is 115 miles (185 km) long, and drains a total land area of 3,790 square miles (9,800 km2).
The Uintah tribe, once a small band of the Ute people, and now is a tribe of multiple bands of Utes that were classified as Uintahs by the U.S. government when they were relocated to the Ute Indian Tribe of the Uintah and Ouray Reservation. The bands included the San Pitch, Pahvant, Seuvartis, Timpanogos and Cumumba Utes.
Ouray is an unincorporated community in west‑central Uintah County, Utah, United States.
The Wasatch Formation (Tw) is an extensive highly fossiliferous geologic formation stretching across several basins in Idaho, Montana Wyoming, Utah and western Colorado. It preserves fossils dating back to the Early Eocene period. The formation defines the Wasatchian or Lostcabinian, a period of time used within the NALMA classification, but the formation ranges in age from the Clarkforkian to Bridgerian.
The Duchesne River Formation is a geologic formation in the Uintah Basin of northeastern Utah. It was originally named the Duchesne Formation by Carnegie Museum paleontologist OA Peterson, and modified to the Duchesne River Formation by Carnegie Museum paleontologist JL Kay because Duschesne Formation was previously used for a Jurassic limestone. In naming the formation, no type section was given, only that it is named for the Duchesne River, which flows roughly southeast and east to join the Green River.
The Mesaverde Group is a Late Cretaceous stratigraphic group found in areas of Colorado, New Mexico, Utah, and Wyoming, in the Western United States.
