Alluvial fans are triangular-shaped deposits of water-transported material referred to as alluvium. They are an example of an unconsolidated sedimentary deposit and tend to be larger and more prominent in arid to semi-arid regions; these alluvial fans form in elevated or mountainous regions where there is a rapid change in slope from a high to low gradient. The river or stream carrying the sediment flows at a high velocity due to the high slope angle, why coarse material is able to remain in the flow; when the slope decreases into a plain or plateau, the stream loses the energy it needs to move its sediment. Deposition subsequently occurs and the sediment spreads out, creating an alluvial fan. Three primary zones occur within an alluvial fan which includes the proximal fan, medial fan, the distal fan. Alluvial fans can exist on a wide spectrum of size scale. For example, alluvial fans can be on the order of only a few meters at its base and can be as large as 150 kilometers with a slope of 1.5-25 degrees.
When numerous rivers/streams converge into a single plain, the fans can combine to form a continuous apron. In arid to semi-arid environments, this is referred to as a bajada and in humid climates the continuous fan apron is called piedmont alluvial fans; as a stream's gradient decreases, it drops coarse-grained material. It makes swagger of the channel and forces it to change direction and build up a mounded or shallow conical fan shape; the deposits are poorly sorted. This fan shape can be explained with a thermodynamic justification: the system of sediment introduced at the apex of the fan will tend to a state which minimizes the sum of the transport energy involved in moving the sediment and the gravitational potential of material in the fan. There will be iso-transport energy lines forming concentric arcs about the discharge point at the apex of the fan, thus the material will tend to be deposited about these lines, forming the characteristic fan shape. The sediment that results from erosion in elevated or mountainous regions flows into the primary streams in the region where the streams act as a drainage system and carries the sediment to the alluvial plain.
Due to the high degree of slope, the river/streams are classified as straight channels. Directly at the mouth of the feeder stream in the alluvial plain, the fan is narrow and is still subjected to high energy from the high degree of slope. Once the sediment exits the feeder stream, the sediment is no longer confined to the channel walls. With this unconfinement, the sediments begin to fan out; the alluvial fan becomes wider with increasing distance from the mouth of the canyon. When there is enough space in the alluvial plain for all of the sediment deposits to fan out without contacting other valleys walls or rivers, an unconfined alluvial fan develops. Unconfined alluvial fans allow sediments to fan out and the shape of the fan is not influenced by other topological features; when the alluvial plain is narrow or short parallel to depositional flow, the fan shape is affected. The biggest natural hazard on alluvial fans are floods and debris flows. Floods on alluvial fans are flash floods: they occur with little to no warning have high velocities and sediment-transporting capability, are of short duration.
Debris flows are a type of landslide, defined as a spatially continuous moving mass of water and material, composed of coarse debris. A modern occurrence of an alluvial fan is photographed in Figure 1 in the semi-arid region between the Kunlun and Altun mountain ranges that form the southern border of the Taklamakan Desert in northwest China; this particular fan is 60 kilometers in total length and is of significance because one part of the alluvial fan is still considered active. An alluvial fan is considered active when there is still a sediment source continually feeding the fan sediment. One portion of the fan has flowing streams that are continually depositing sediment and the fan is still prograding into the alluvial plain; the feeder channels consist of straight channels as well as instances of braided channels because of the large volume of sediment sourced from the local uplands. Various environmental and geologic factors exhibit control on the deposition of alluvial fan deposits; the primary factor in alluvial fan environments is sediment supply.
The sediment that comprise the bedload and suspended load of the regional streams is sourced from the erosion of the associated highlands in the area. Therefore, a high erosion rate corresponds to an increase in sediment in the streams which affects stream morphology. For example, a high sediment load is associated with braided streams entering and within the alluvial plain. Medium to low sediment loads in the feeder stream results in straight channels.4 Alluvial fans are built in response to erosion induced by tectonic uplift to create nearby mountain ranges/highlands. This uplift is necessary for a source of erosion where the sediments are deposited in an alluvial fan regime in the alluvial plain. Tectonics can affect the degree of stream gradients and cause changes in base level which may lead to incision into fan surfaces in the distal zone of the deposit. An increase in precipitation would allow a higher water level in the streams which would allow for a greater amount of sediment to be carried along with it to be deposited in the alluvial plain.
There are three primary zones, or facies, that exist within an alluvial fan deposit which include the proximal fan, medial fan, distal fan with an overal
Box Elder County, Utah
Box Elder County is a county at the northwestern corner of Utah, United States. As of 2017, the estimated population is 54,079, its county seat and largest city is Brigham City. The county was named for the box elder trees. Box Elder County is part of the Ogden-Clearfield, UT Metropolitan Statistical Area, included in the Salt Lake City-Provo-Orem, UT Combined Statistical Area; the county was created by the Utah Territory legislature on January 5, 1856, with territory partitioned from Weber County. Its boundaries were altered in 1862 by adjustments between counties, in 1866 when all its area in the now-existent state of Nevada was formally partitioned; the county boundaries were altered in 1880 by adjustments between Salt Lake and Weber counties. Its boundary has remained unchanged since 1880; the California Trail followed Goose Creek from a point just north of the Idaho/Utah border southwest across northwestern Box Elder County to Little Goose Creek in northeastern Elko County, Nevada. The link-up of the first transcontinental railroad occurred at Promontory Summit, Utah in 1869.
The famous Spiral Jetty was built on the north shore of the Great Salt Lake in Box Elder County in 1970. Box Elder County lies at the NW corner of Utah, its west border abuts the east border of the state of Nevada and its north border abuts the south border of the state of Idaho. Its territory includes large tracts of barren desert, contrasted by forested mountains; the Wasatch Front lies along the south-eastern border. The terrain slopes to the south, although the NW corner of the county slopes to the north, allowing runoff from that area to flow to the Snake River drainage; the county's highest point is a mountain ridge near the NW corner, at 9,180' ASL. The county has a total area of 6,729 square miles, of which 5,746 square miles is land and 984 square miles is water, it is the fourth-largest county in Utah by area. In the east lie the Wellsville Mountains, a branch of the Wasatch Range. In the west is a large uninhabited desert area; the Great Salt Lake lies in the southeastern corner of the county.

The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
The Pilot Range is a mountain range straddling the border of Box Elder County and Elko County, United States. Lying 50 miles west of the Great Salt Lake, the range forms part of the north-west border of the Great Salt Lake Desert; the range reaches a maximum elevation of 10,716 feet at the summit of Pilot Peak. Most of the range thus has no access restrictions, its principal uses are mining, livestock grazing, seasonal elk and deer hunting. The Pilot Range begins about 15 miles north of the community of West Wendover, continues north-northeastwards for 30 miles; the abandoned railroad town of Lucin, Utah lay two miles north-east. The range runs SSW to NNE, with various canyons spurring west off a prominent ridgeline, it covers an area of about 51,200 acres. Elevation varies from a base of 5,000 feet feet to ] to 10,716 foot Pilot Peak. Other significant summits in the range are Copper Mountain, Bald Eagle Mountain, Rhyolite Butte. To the east of the range lie Pilot Valley Playa and its springs. Several fresh and salty springs flow from the base of the alluvial fans at the base of the range.
The largest is a habitat for the threatened Lahontan cutthroat trout. Vegetation varies from Engelmann Spruce and Limber Pine in the highest elevations, pinyon pine, mountain mahogany, juniper in the middle elevations and grass in the south-face slopes and ridge-tops, rabbitbrush and greasewood in the lower elevations; the Pilot Range cinquefoil is a rare species of plant which can be found in the Pilot Range and a few other ranges nearby.

Great Basin Desert
The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range. The desert is a geographical region that overlaps the Great Basin shrub steppe defined by the World Wildlife Fund, the Central Basin and Range ecoregion defined by the U. S. Environmental Protection Agency and United States Geological Survey, it is a temperate desert with snowy winters. The desert spans a large part of the state of Nevada, extends into western Utah, eastern California, Idaho; the desert is one of the four biologically defined deserts in North America, in addition to the Mojave and Chihuahuan Deserts. Basin and range topography characterizes the desert: wide valleys bordered by parallel mountain ranges oriented north-south. There are more than 33 peaks within the desert with summits higher than 9,800 feet, but valleys in the region are high, most with elevations above 3,900 feet; the biological communities of the Great Basin Desert vary according to altitude: from low salty dry lakes, up through rolling sagebrush valleys, to pinyon-juniper forests.
The significant variation between valleys and peaks has created a variety of habitat niches, which has in turn led to many small, isolated populations of genetically unique plant and animal species throughout the region. According to Grayson, more than 600 species of vertebrates live in the floristic Great Basin, which has a similar areal footprint to the ecoregion. Sixty-three of these species have been identified as species of conservation concern due to contracting natural habitats; the ecology of the desert varies across geography, also. The desert’s high elevation and location between mountain ranges influences regional climate: the desert formed by the rain shadow of the Sierra Nevada that blocks moisture from the Pacific Ocean, while the Rocky Mountains create a barrier effect that restricts moisture from the Gulf of Mexico. Different locations in the desert have different amounts of precipitation, depending on the strength of these rain shadows; the environment is influenced by Pleistocene lakes that dried after the last ice age: Lake Lahontan and Lake Bonneville.
Each of these lakes left different amounts of alkalinity. The Great Basin Desert is defined by its animals and plants. Scientists have different definitions of the Great Basin Desert, which are defined by negatives. J. Robert Macey defines the "Great Basin scrub desert as lacking creosote bush." The Great Basin Desert includes several arid basins lacking Larrea tridentata such as the "Chalfant, Hammil and Queen valleys," as well as all but the southeast portion of the Owens Valley. Conversely, the "Panamint and Eureka valleys" have creosote bush, unlike the Deep Springs Valley which includes part of the Great Basin scrub desert; the study and definition of ecoregions can indicate the boundaries of the Great Basin Desert. In 1987, J. M. Omernik defined a desert ecoregion between the Sierra Nevada and Wasatch Range, naming it the "Northern Basin and Range" ecoregion. In 1999, the U. S. EPA renamed the "Northern Basin and Range" to "Central Basin and Range" and the " High Desert" to the "Northern Basin and Range".
The World Wildlife Fund adopted the Basin and Range ecoregions from Omernik, but excised a small region of high-altitude areas which contain Holocene refugia, from the former "Northern Basin and Range" ecoregion and renamed it the "Great Basin Shrub Steppe". Although the EPA had refined the boundaries of the Central Basin and Range ecoregion by 2003, when USGS geographer Christopher Soulard wrote his reports on the region, his maps used the 1999 boundary for the "Central Basin and Range", the same as the "Great Basin Shrub Steppe", he states. This article describes the general ecology of the region, including the high-elevation areas, does not rely on minor differences in the definitions of the ecoregion or desert. See Great Basin montane forests for more specific details on the high-elevation ecoregion; the climate of the Great Basin desert is characterized by extremes: hot, dry summers and cold, snowy winters. This is the climate of the high desert; the Great Basin desert climate begins with the Sierra Nevada in eastern California.
Rising 14,000 feet above sea level, this mountain range casts a large rain shadow over the desert. Weather coming in from the Pacific Ocean loses its moisture as rain and snow as it is forced up and over the steep mountains. By the time it reaches the east side of the mountains, little moisture is left to bring to the desert; the rain shadow effect is more pronounced closer to the Sierra Nevada, with yearly precipitation in the Great Basin desert averaging 9 inches in the west and 12 inches inches in the east. Moisture that manages to reach the ecoregion tends to precipitate as rain and snow in higher elevations over the region’s long, parallel mountains. Any precipitation that falls within the desert fails to drain either to the Atlantic Ocean or to the Pacific Ocean. Instead, precipitation drains to ephemeral or saline lakes via streams, or disappears via evaporation or absorption into the soil; the desert is the coldest of the deserts in North America. On any given day, the weather across the Great Basin desert is variable.
The region is mountainous, the temperatures vary depending on the elevation. In general, temperature decreases 3.6 degrees F for every 10
Fish Springs Range
The Fish Springs Range is a 16-mile long narrow, north-trending mountain range located in center-west Juab County, Utah. The northeast of the range borders the Fish Springs National Wildlife Refuge; the Fish Springs Range lies at the south of the Great Salt Lake Desert. The sequence of these landforms west-to-east, are Snake Valley, Confusion Range, Tule Valley-, House Range, Whirlwind Valley, Drum Mountains; the south of the range borders the north of Tule Valley. The Fish Springs Range is north-south trending, narrow, the range is veryslightly "arc-shaped", curved, to the west. A small sub-range, Middle Range, lies 6.5-mi southwest, towards the Confusion Range. Southeast lies the extreme north foothills of the House Range. Fish Springs Flat borders the east of the range, west of the range lies a satellite sub-peak, The Honeycombs, 5,686 feet; the highpoint of the range in the center-south is George H. Hansen Peak, 5,686 feet; the Fish Springs Range and wildlife refuge can be accessed from the west from Trout Creek.
From the east, access can be from the Dugway Range region by unimproved roads, southeast by the same from Delta, Utah State Route 174. George H. Hansen Peak, mountainzone Fish Springs & Fish Springs Range, Fish Springs Range
Great Salt Lake
The Great Salt Lake, located in the northern part of the U. S. state of Utah, is the largest salt water lake in the Western Hemisphere, the eighth-largest terminal lake in the world. In an average year the lake covers an area of around 1,700 square miles, but the lake's size fluctuates due to its shallowness. For instance, in 1963 it reached its lowest recorded size at 950 square miles, but in 1988 the surface area was at the historic high of 3,300 square miles. In terms of surface area, it is the largest lake in the United States, not part of the Great Lakes region; the lake is the largest remnant of Lake Bonneville, a prehistoric pluvial lake that once covered much of western Utah. The three major tributaries to the lake, the Jordan and Bear rivers together deposit around 1.1 million tons of minerals in the lake each year. As it is endorheic, it has high salinity and its mineral content is increasing. Due to the high density resulting from its mineral content, swimming in the Great Salt Lake is similar to floating.
Its shallow, warm waters cause frequent, sometimes heavy lake-effect snows from late fall through spring. Although it has been called "America's Dead Sea", the lake provides habitat for millions of native birds, brine shrimp and waterfowl, including the largest staging population of Wilson's phalarope in the world; the Great Salt Lake is a remnant of a much larger prehistoric lake called Lake Bonneville. At its greatest extent, Lake Bonneville spanned 22,400 square miles, nearly as large as present-day Lake Michigan, ten times the area of the Great Salt Lake today. Bonneville reached 923 ft at its deepest point, covered much of present-day Utah and small portions of Idaho and Nevada during the ice ages of the Pleistocene Epoch. Lake Bonneville existed until about 16,800 years ago, when a large portion of the lake was released through the Red Rock Pass in Idaho. With the warming climate, the remaining lake began to dry, leaving the Great Salt Lake, Utah Lake, Sevier Lake, Rush Lake behind; the Shoshone and Paiute have lived near the Great Salt Lake for thousands of years.
At the time of Salt Lake City's founding, the valley was within the territory of the Northwestern Shoshone. One of the local Shoshone tribes, the Western Goshute tribe, referred to the lake as Pi'a-pa, meaning "big water", or Ti'tsa-pa, meaning "bad water"; the Great Salt Lake entered written European history through the records of Silvestre Vélez de Escalante, who learned of its existence from the Timpanogos Utes in 1776. No European name was given to it at the time, it was not shown on the map by Bernardo Miera y Pacheco, the cartographer for the expedition. In 1824, it was observed independently, by Jim Bridger and Etienne Provost. Shortly thereafter other trappers walked around it. Most of the trappers, were illiterate and did not record their discoveries; as oral reports of their findings made their way to those who did make records, some errors were made. Escalante had been on the shores of Utah Lake, it was the larger of the two lakes. Other cartographers charted Lake Timpanogos as the largest lake in the region.
As people came to know of the Great Salt Lake, they interpreted the maps to think that "Timpanogos" referred to the Great Salt Lake. On some maps the two names were used synonymously. In time "Timpanogos" was dropped from the maps and its original association with Utah Lake was forgotten. In 1843, John C. Fremont led the first scientific expedition to the lake, but with winter coming on, he did not take the time to survey the entire lake; that happened in 1850 under the leadership of Howard Stansbury. John Fremont's overly glowing reports of the area were published shortly after his expedition. Stansbury published a formal report of his survey work which became popular, his report of the area included a discussion of Mormon religious practices based on Stansbury's interaction with the Mormon community in Great Salt Lake City, established three years earlier in 1847. Beginning in November 1895, artist and author Alfred Lambourne spent a year living on the remote Gunnison Island, where he wrote a book of musing and poetry, Our Inland Sea.
From November 1895 to March 1896, he was alone. In March, a few guano sifters arrived to harvest and sell the guano of the nesting birds as fertilizer. Lambourne included musings about these guano sifters in his work. Lambourne left the island early in the winter of 1896 along with the first group of guano sifters; the Great Salt Lake lends its name to Salt Lake City named "Great Salt Lake City" by the president of The Church of Jesus Christ of Latter-day Saints Brigham Young, who led a group of Mormon pioneers to the Salt Lake Valley southeast of the lake on July 24, 1847. The lake lies in parts of five counties: Box Elder, Tooele and Salt Lake. Salt Lake City and its suburbs are located to the south-east and east of the lake, between the lake and the Wasatch Mountains, but land around the north and west shores are uninhabited; the Bonneville Salt Flats are to the west, the Oquirrh and Stansbury Mountains rise to the south. The Great Salt Lake is fed by several minor streams; the three major rivers are each fed directly or indirectly from the Uinta Mountain range in northeastern Utah.
The Bear River starts on the north slope of the Uintas and flows nort
