Heliobatis radians (stingray), Green River Formation, Fossil Butte National Monument. The Green River Formation is an Eocene geologic formation that records the sedimentation in a group of intermountain lakes in three basins along the present-day Green River in Colorado, Wyoming, and Utah. The sediments are deposited in very fine layers, a dark ...
The Green River Formation is a geological formation located in the Intermountain West of the United States, in the states of Colorado, Utah, and Wyoming.It comprises sediments deposited during the Early Eocene in a series of large freshwater lakes: Lake Gosiute, Lake Uinta, and Fossil Lake (the last containing Fossil Butte National Monument).
Meander cutoff. A meander cutoff is a natural form of a cutting or cut in a river occurs when a pronounced meander (hook) in a river is breached by a flow that connects the two closest parts of the hook to form a new channel, a full loop. The steeper drop in gradient (slope) causes the river flow gradually to abandon the meander which will silt ...
(The Green River continues flowing south through Gray Canyon.) Desolation Canyon is situated between the West Tavaputs Plateau on the west and the East Tavaputs Plateau on the east. At its deepest point, a relief of over 5,000 feet (1,500 m) exists from river level to the unseen rim of the Tavaputs Plateau. [5]
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 730 miles (1,170 km) long, beginning in the Wind River Mountains of Wyoming and flowing through ...
Sedimentation results in the formation of depositional landforms and the rocks that constitute the sedimentary record. [6] The building up of land surfaces by sedimentation, particularly in river valleys, is called aggradation. [7] The rate of sedimentation is the thickness of sediment accumulated per unit time. [8]
Flaming Gorge Dam is a concrete thin- arch dam on the Green River, a major tributary of the Colorado River, in northern Utah in the United States. Flaming Gorge Dam forms the Flaming Gorge Reservoir, which extends 91 miles (146 km) into southern Wyoming, submerging four distinct gorges of the Green River. The dam is a major component of the ...
The river basin itself is not mainly sediment, but rather consists of metamorphic rock. The humid subtropical climate provides for moderate temperatures and relatively mild winters. The precipitation for the areas around the Green River typically ranges from 100 to 140 centimeters annually.
