Mountain Home Range
The Mountain Home Range is a north-south trending mountain range in western Beaver County in southwest Utah, United States. It is part of the Basin and Range Province. It is bound by Hamlin Valley to the west, Snake Valley (part of this area known as Antelope Valley on some maps) to the north, Pine Valley to the east, and trends into the Indian Peak Range to the south. Collectively, the Mountain Home Range and Indian Peak Range are known as the Needle Mountains due to their jagged nature. The highest peak in the range, known simply as the 'Needle benchmark,' is tall. The range is very uncommonly used by humans, and is more known for wildlife and wild horses. Geology The northern part of the range is made of Paleozoic carbonate rocks which are part of a long structural trend of rocks that go through the Burbank Hills, Conger Range, and Confusion Range. This is highlighted by a massive (30 by 50 mile) syncline. The southern part of the range is made of mid-Tertiary ignimbrite ...

Carbonate Rock
Carbonate rocks are a class of sedimentary rocks composed primarily of carbonate minerals. The two major types are limestone, which is composed of calcite or aragonite (different crystal forms of CaCO3), and dolomite rock (also known as dolostone), which is composed of mineral dolomite (CaMg(CO3)2). Calcite can be either dissolved by groundwater or precipitated by groundwater, depending on several factors including the water temperature, pH, and dissolved ion concentrations. Calcite exhibits an unusual characteristic called retrograde solubility in which it becomes less soluble in water as the temperature increases. When conditions are right for precipitation, calcite forms mineral coatings that cement the existing rock grains together or it can fill fractures. Karst topography and caves develop in carbonate rocks because of their solubility in dilute acidic groundwater. Cooling groundwater or mixing of different groundwaters will also create conditions suitable for cave ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Ranges Of Utah
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Ignimbrite
Ignimbrite is a type of volcanic rock, consisting of hardened tuff. Ignimbrites form from the deposits of pyroclastic flows, which are a hot suspension of particles and gases flowing rapidly from a volcano, driven by being denser than the surrounding atmosphere. New Zealand geologist Patrick Marshall (1869-1950) coined the term ''ignimbrite'' from the Latin ''igni-'' [fire] and ''imbri-'' [rain]. Ignimbrites are made of a very poorly sorted mixture of volcanic ash (or tuff when Lithification, lithified) and pumice lapilli, commonly with scattered lithic fragments. The ash is composed of glass shards and crystal fragments. Ignimbrites may be loose and unconsolidated, or lithified (solidified) rock called lapilli-tuff. Near the volcanic source, ignimbrites often contain thick accumulations of lithic blocks, and distally, many show meter-thick accumulations of rounded cobbles of pumice. Ignimbrites may be white, grey, pink, beige, brown, or black depending on their composition and d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied. In the early d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syncline
In structural geology, a syncline is a fold with younger layers closer to the center of the structure, whereas an anticline is the inverse of a syncline. A synclinorium (plural synclinoriums or synclinoria) is a large syncline with superimposed smaller folds. Synclines are typically a downward fold (synform), termed a synformal syncline (i.e. a trough), but synclines that point upwards can be found when strata have been overturned and folded (an antiformal syncline). Characteristics On a geologic map, synclines are recognized as a sequence of rock layers, with the youngest at the fold's center or ''hinge'' and with a reverse sequence of the same rock layers on the opposite side of the hinge. If the fold pattern is circular or elongate, the structure is a basin. Folds typically form during crustal deformation as the result of compression that accompanies orogenic mountain building.

Confusion Range
The Confusion Range is a north-south trending mountain range in west-central Utah, United States. It is bounded by Snake Valley to the west, Tule Valley to the east, the Great Salt Lake Desert to the north, and the Ferguson Desert to the south. The range trends into the Burbank Hills, Mountain Home Range, and the Wah Wah Mountains to the south. In the central part of the range, an offshoot of the mountains to the west is known as the Conger Range. The Confusion Range is named for its "rugged isolation and confusing topography."Van Cott, J. W., 1990, Utah Place Names, The highest peaks in the range are Conger Mountain , which is 7,713 feet tall, and King Top , which is 8,350 feet tall. The geology of the Confusion range is deformed Silurian to Permian limestones, dolomites, and shales.Chronic, Halka, 1990, Roadside Geology of Utah, There are three main ways to travel through the Confusion Range: *Around the north end, from Callao, Utah to Sand Pass *On old Highway 6/50, ...

Conger Range (Utah)
The Conger Range, also called the Conger Mountains, is a mountain range in Quttinirpaaq National Park on Ellesmere Island, Nunavut, Canada, beginning about west of Mount Osborne. It is part of the Arctic Cordillera which is a vast dissected mountain system extending from Ellesmere Island to the northernmost tip of Labrador and northeastern Quebec. The Conger Range is a structural extension of the Garfield Range and continues into the highlands north of the head of Hare Fiord. The overall extent of the range is about . Most of its peaks are ice-covered, although nearly all of the southern slopes are ice-free. Many of the valleys between the peaks are filled with glacial tongues spilling out to the south from the Grand Land Ice Cap. Its highest point is Mount Biederbick at . The Conger Range was named by American Polar explorer Adolphus Greely Adolphus Washington Greely (March 27, 1844 – October 20, 1935) was a United States Army officer and polar explorer.

Burbank Hills
The Burbank Hills are a small northwest-southeast mountain range in western Utah, United States that lie entirely within the Hamlin-Snake Watershed, between the Snake Range and the Ferguson Desert. It is bounded by Snake Valley to the north, west, and south; and trends into the Tunnel Springs Mountains, to the southeast, opposite the Antelope Valley on its southeast border. It was named after the settlement of Burbank, Utah, and Margie Burbank Clay, the wife of local Judge E. W. Clay in the 1870s. The Burbank Hills has numerous ATV trails and fossils. Geology The structural trend of rocks in the range is similar to rocks in the northern Mountain Home Range to the southwest and Conger Range and central Confusion Range to the northeast. These are chiefly Devonian to Permian carbonate rocks arranged in a massive syncline In structural geology, a syncline is a fold with younger layers closer to the center of the structure, whereas an anticline is the inverse of a syncline. ...

Paleozoic
The Paleozoic (or Palaeozoic) Era is the earliest of three geologic eras of the Phanerozoic Eon. The name ''Paleozoic'' ( ;) was coined by the British geologist Adam Sedgwick in 1838 by combining the Greek words ''palaiós'' (, "old") and ''zōḗ'' (), "life", meaning "ancient life" ). It is the longest of the Phanerozoic eras, lasting from , and is subdivided into six geologic periods (from oldest to youngest): # Cambrian # Ordovician # Silurian # Devonian # Carboniferous # Permian The Paleozoic comes after the Neoproterozoic Era of the Proterozoic Eon and is followed by the Mesozoic Era. The Paleozoic was a time of dramatic geological, climatic, and evolutionary change. The Cambrian witnessed the most rapid and widespread diversification of life in Earth's history, known as the Cambrian explosion, in which most modern phyla first appeared. Arthropods, molluscs, fish, amphibians, reptiles, and synapsids all evolved during the Paleozoic. Life began in the ocean ...

Utah
Utah ( , ) is a state in the Mountain West subregion of the Western United States. Utah is a landlocked U.S. state bordered to its east by Colorado, to its northeast by Wyoming, to its north by Idaho, to its south by Arizona, and to its west by Nevada. Utah also touches a corner of New Mexico in the southeast. Of the fifty U.S. states, Utah is the 13th-largest by area; with a population over three million, it is the 30th-most-populous and 11th-least-densely populated. Urban development is mostly concentrated in two areas: the Wasatch Front in the north-central part of the state, which is home to roughly two-thirds of the population and includes the capital city, Salt Lake City; and Washington County in the southwest, with more than 180,000 residents. Most of the western half of Utah lies in the Great Basin. Utah has been inhabited for thousands of years by various indigenous groups such as the ancient Puebloans, Navajo and Ute.

Needle Mountains (Nevada-Utah)
The Needle Mountains are a subrange of the San Juan Mountains of the Rocky Mountains located in the southwestern part of the U.S. State of Colorado. Much of the range is protected in the Weminuche Wilderness of the San Juan National Forest. The range is notable for having some of the most rugged mountains in the state, and includes many technical climbs and scrambles. A small but dramatic east–west subrange in the northern section is known as the Grenadier Range. Geology Unlike the rest of the San Juan Mountains, which are volcanic in origin, the Needle Mountains (along with the Grenadier Range) are a mass of uplifted Precambrian rocks. They consist chiefly of quartzite, granite, and amphibolite. The mountains are referred to as the Needle Mountains Uplift. Notable peaks * Mount Eolus, 14,089 ft * Windom Peak, 14,082 ft * Sunlight Peak, 14,059 ft * Pigeon Peak, 13,972 ft * Vestal Peak, 13,864 ft (Grenadier Range) * Turret Peak, 13,835 ft * Ja ...
