Uinta Mountains
The Uinta Mountains ( ) are an east-west trending chain of mountains in northeastern Utah extending slightly into southern Wyoming in the United States. As a subrange of the Rocky Mountains, they are unusual for being the highest range in the contiguous United States running east to west, and lie approximately east of Salt Lake City. The range has peaks ranging from , with the highest point being Kings Peak, also the highest point in Utah. The Mirror Lake Highway crosses the western half of the Uintas on its way to Wyoming. Etymology The name "Uinta" derives from the Ute word ''Yoov-we-teuh'', meaning "pine forest" or "pine tree". Geology The Uinta Mountains are Laramide uplifted metasedimentary rocks deposited in an intracratonic basin in southwest Laurentia during the time of the breakup of the supercontinent Rodinia. The marine and fluvial metasedimentary rocks in the core of the Uinta Mountains are of Neoproterozoic age (between about 700 million and 760 million years old ...

Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Summit County, Utah
Summit County is a county in the U.S. state of Utah, occupying a rugged and mountainous area. As of the 2010 United States Census, the population was 36,324. Its county seat is Coalville, and the largest city is Park City. History The county was created by the Utah Territory legislature on January 13, 1854, with its description containing a portion of the future state of Wyoming. It was not organized then but was attached to Great Salt Lake County for administrative and judicial purposes. The county government was completed by March 4, 1861, so its attachment to the other county was terminated. The county boundaries were altered in 1856 and in 1862. In 1868 the Wyoming Territory was created by the US government, effectively de-annexing all Summit County areas falling within the new territory. The boundaries were further altered in 1872 and 1880. Its final alteration occurred on January 7, 1918, when Daggett's creation took a portion of its eastern territory. Its boundary has r ...

Fort Bridger
Fort Bridger was originally a 19th-century fur trading outpost established in 1842, on Blacks Fork of the Green River, in what is now Uinta County, Wyoming, United States. It became a vital resupply point for wagon trains on the Oregon Trail, California Trail, and Mormon Trail. The Army established a military post here in 1858 during the Utah War, until it was finally closed in 1890. A small town, Fort Bridger, Wyoming, remains near the fort and takes its name from it. Bridger's Trading Post The post was established by the mountain man Jim Bridger, after whom it is named, and Louis Vasquez. In December 1843, Bridger wrote Pierre Chouteau Jr., "I have established a small fort, with a blacksmith shop and a supply of iron in the road of emigrants on Black Fork of Green River, which promises fairly." According to Stanley Vestal, "His fort consisted simply of an eight-foot stockade, with a corral adjoining on the north. Within that stockade stood four log cabins with flat dirt roof ...

Hanging Wall
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Structural Trap
In petroleum geology, a trap is a geological structure affecting the reservoir rock and caprock of a petroleum system allowing the accumulation of hydrocarbons in a reservoir. Traps can be of two types: stratigraphic or structural. Structural traps are the most important type of trap as they represent the majority of the world's discovered petroleum resources. Structural traps A structural trap is a type of geological trap that forms as a result of changes in the structure of the subsurface, due to tectonic, diapiric, gravitational and compactional processes. Anticlinal trap An anticline is an area of the subsurface where the strata have been pushed into forming a domed shape. If there is a layer of impermeable rock present in this dome shape, then hydrocarbons can accumulate at the crest until the anticline is filled to the ''spill point'' - the highest point where hydrocarbons can escape the anticline. This type of trap is by far the most significant to the hydrocarbon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
