Manti-La Sal National Forest
The Manti-La Sal National Forest covers more than 1.2 million acres and is located in the central and southeastern parts of the U. S. state of Utah and the extreme western part of Colorado. The forest is headquartered in Price, with ranger district offices in Price, Ephraim and Monticello; the maximum elevation is Mount Peale in the La Sal Mountains, reaching 12,721 feet above sea level. The La Sal Mountains are the second highest mountain range in Utah after the Uintas. Parts of the forest are included in the Bears Ears National Monument; the La Sal Mountain loop road leads from Castle Valley to Geyser Pass and back down to Moab. Scenic Oowah Lake can be found within the forest. In descending order of land area, the forest is located in parts of San Juan, Emery, Grand and Sevier counties in Utah, as well as Montrose, Mesa counties in Colorado. Forest headquarters is located in Utah. District offices are located in Ephraim, Moab and Price; the forest was established as the Manti Forest Reserve by the General Land Office on May 29, 1903 with 584,640 acres.
On July 1, 1915 Nebo National Forest was added, La Sal National Forest on November 11, 1949. On August 28, 1950 the name became Manti-La Sal National Forest. On December 28, 2016 President Barack Obama proclaimed the 1.35 million acre Bears Ears National Monument, which includes most of the Monticello Ranger District on the forest and the Dark Canyon Wilderness. Manti La Sal National Forest is popular for recreation; the northern district on the Wasatch Plateau is well known for the Skyline Drive, an unpaved road tracing along the backbone of the plateau. There is an extensive ATV trail system in the forest there; the Moab District in the La Sal Mountains contains a number of hiking trails, as well as views over the desert regions of Canyonlands National Park and Arches National Park. The Monticello District is home the Manti La Sal National Forest's only wilderness area, the Dark Canyon Wilderness, a vast, remote canyon area. List of U.

Monticello is a city located in San Juan County, is the county seat. It is the second most populous city in San Juan County, with a population of 1,958 at the 2000 census; the Monticello area was settled in July 1887 by pioneers from The Church of Jesus Christ of Latter-day Saints. Monticello, named in honor of Thomas Jefferson's estate, became the county seat in 1895 and was incorporated as a city in 1910. Monticello, along with much of San Juan County, experienced an increase in population and economic activity during the uranium boom from the late 1940s to the early 1960s. Several uranium and vanadium mines were opened in the area, a uranium processing mill was operated in Monticello by the Federal Government from 1948 to 1960. Following the uranium boom, a massive cleanup project was conducted by the U. S. Department of Energy from 1989 to 2004 to remove radioactive material from lands and buildings and to restore the land occupied by the mill. An 18-hole golf course, The Hideout, was built near the reclaimed site of the uranium mill using DOE cleanup funding in 2000.
The Hideout has been ranked No. 2 Golf Course in Utah and the No. 23 Municipal Golf Course in the U. S. In 1998, The Church of Jesus Christ of Latter-day Saints dedicated the Monticello Utah Temple, the first in a series of mini temples and the 53rd temple for the church. Monticello rests at the base of the Abajo Mountains on the Colorado Plateau; the Old Spanish Trail trade route passed through the area of Monticello from 1829 into the 1850s. Monticello was one of the many cities established by Mormon pioneers in the Utah Territory, which became the State of Utah. Farming and uranium mining have all played an important role in the economy and history of the town. Early members of The Church of Jesus Christ of Latter-day Saints began the first full-scale settling of what is now known as San Juan County, Utah. Few white residents had settled along the San Juan River prior to the arrival of the Mormon pioneers from the San Juan Expedition. After passing through Hole-In-The-Rock, the pioneers arrived in the San Juan County area and settled in Bluff on 6 April 1880.
In that year, on a journey to northern Utah from the San Juan River settlements, Apostles Erastus Snow and Brigham Young, Jr. passed through the current site of Monticello. They were quite impressed by it, this encounter was one of the key factors behind LDS settlement there a few years later. After struggling to farm along the unpredictable San Juan River, leaders began to look to settle the higher country at the base of the Abajo Mountains known as the Blue Mountains, where several streams and springs descended from the mountain. Piute Springs, Soldier’s Spring, Montezuma Creek were a few of the water sources in the area named by passersby. In March 1886, Francis A. Hammond, the LDS Stake President of San Juan County, sent scouts from Bluff to identify possible locations for settlements near the water sources of the Blue Mountains; the scouts found that a few people had begun to utilize the land. The first white man to build a cabin in the Monticello area was cattleman Patrick O'Donnell in 1879.
The North and South Forks of Montezuma Canyon, through which Montezuma Creek flows, were being utilized when the scouts arrived. The Kansas and New Mexico Cattle and Land Company, operated by Edmund and Harold Carlisle, was located a few miles north of what is now Monticello, the L. C. outfit was headquartered in the South Fork of Montezuma Canyon. Notwithstanding the fact that others were utilizing the land, Hammond sent the families of George A. Adams, Frederick I. Jones, Parley R. Butt and Charles E. Walton from Bluff to establish a new settlement at what is now Monticello, they first set up camp at Verdure near the South Fork of Montezuma Creek on March 11, 1887, six miles south of what is now Monticello. By the first part of July 1887, the men had begun to plant crops, survey an irrigation ditch, layout a townsite in the present-day Monticello area. Conflicts soon began with the Carlisle cowboys and Ute Indians over water and land rights, resulting in warning shots, heated disputes, legal battles.
Learning from lawyers that the Carlisles had little legal claim to any of the region, the Mormons claimed all the water from the South Fork and three-fourths of the water from the North Fork. In the spring of 1888, the Adams and Butt families remained in Verdure while the rest of the settlers moved to North Montezuma and began construction of the town. Early names for the settlement were North Montezuma Creek, Piute Springs, Hammond, after the stake president. In a formal meeting in 1888, three names were under consideration: North Montezuma and the biblical name, Antioch. None of the names were approved by the younger members of the community; when Hammond recommended Monticello, in honor of Thomas Jefferson’s estate, everyone approved and it was accepted. In 1903 the Utah State Agricultural College in Logan established an experimental station in Verdure where various dry-farming techniques were tested for thirteen years; this information spurred the growth of the farming industry in the area.
In 1909 the Enlarged Homestead Act was passed, which provided 320 acres of non-irrigable land for a small price. New farms began to cover the sagebrush lands east of Monticello. Dry farming was a major occupation in the area up through the 1930s and is a vital part of the local economy today; the first phone lines were installed in the community in 1906. The Blue Mountain Irrigation Company organized construction of a combined water and power system in 1917; the San Juan Record, the county newspaper, was established in Monticello by Oscar Walter McConkie in 191
Navajo Mountain is a peak in San Juan County, with its southern flank extending into Coconino County, Arizona. It holds an important place in the traditions of three local Native American tribes; the summit is the highest area on the Navajo Nation. Navajo Mountain is a prominent free-standing laccolith, a dome-shaped body of igneous rock that intruded into sedimentary layers and lifted up the overlying layer; the igneous rock at the core of the mountain is wrapped in sedimentary layers. Such igneous intrusions have been exposed by erosion and well studied in similar mountain ranges on the Colorado Plateau, such as the Henry Mountains, the Abajo Mountains, the La Sal Range; the Colorado Plateau is made of flat-lying layers of sedimentary rock that record paleoclimate extremes ranging from oceans to widespread deserts over the last 1.8 billion years. The peak of Navajo Mountain, at 10,388 feet, is made up of uplifted Dakota Sandstone deposited during the Cretaceous Period; the Navajo Mountain region has special cultural significance to the Navajo people, who know it as Naatsisʼáán.
Together with Rainbow Bridge to the northwest, Navajo Mountain figures prominently as the first settlement area in western Navajo origin stories. Following the military defeat of the Diné by United States forces in 1863, the political landscape was changed by new boundaries and major physical alterations; the establishment of Rainbow Bridge National Monument, the filling of Glen Canyon by Lake Powell in 1963, has facilitated tourism of this remote region. Access to Navajo Mountain is still regulated by the sovereign Navajo Nation, a permit is required to hike in the region. Climbing the mountain itself is forbidden. Before becoming part of the Navajo Nation, the area was inhabited by the Anasazi, or Ancestral Puebloans, their descendants, the Hopi, call Navajo Mountain Tokonave, or "Heart of the Earth". Ruins in the area of Navajo Mountain are still associated with certain Hopi clans, with priests still making pilgrimages to shrines in the area. Before 1933, when the area between the Colorado and San Juan Rivers and the Arizona border was added to the Navajo reservation, the area was known as the Paiute Strip, the mountain itself was known as Paiute Mountain, due to the population of San Juan Paiutes living between the mountain and Monument Valley.

Ute Mountain, is a peak within the Ute Mountains, a small mountain range in the southwestern corner of Colorado. It is on the northern edge of the Ute Mountain Ute Tribe Reservation; the Reservation forms the southwestern corner of Montezuma County. Nomenclature for this peak and its range varies; the highest peak is sometimes known as Sleeping Ute Mountain. All of these forms of the mountain's name and of the range's name can be found on various USGS maps and reports; the Ute Mountains, with a collective profile known as “The Sleeping Ute”, are a dense cluster of peaks 5 by 12 miles in extent and stand in isolation from other mountains. Despite being much lower than Colorado's highest peaks, Ute Mountain is the eighth most topographically prominent peak in the state, due to this isolation, it is notable for its large local relief in all directions its rise of 4,250 ft over the Montezuma Valley to the southeast. The Sleeping Ute is said to resemble a Ute Chief lying on his back with arms folded across his chest.
The mountains were valued as a sacred place by the Weeminuche Ute band. It is still a sacred place to their descendants, the Ute Mountain Ute Tribe and still plays a role in their ceremonies as indicated by the “Sundance Ground” on some topographical maps nestled between The Knees and Horse Peak; the northern part of the mountains were outside the reservation boundaries as reduced following a series of treaties in the late 19th century, but a trade of land now in Mesa Verde National Park 15 miles east, for federal land on the mountain, allowed the reservation boundary to be extended north to McElmo Creek and encompass the entire mountain range. In particular, this means that recreational access to the range by outsiders is restricted. Few roads or trails are found in the mountains, although radio towers and water tanks have been built, a road along Cottonwood Wash from Towaoc nearly reaches the summit of Ute Peak. A Ute Indian legend describes the Sleeping Ute as the sleeping form of a “Great Warrior God, known as a chief” who fell asleep while recovering from wounds received in a great battle with “the Evil Ones”.
Various other forms of the legend can be found. Recognized from many spots up to 50 miles east or west, the profile is best seen from 15 to 25 miles somewhat north of east of the mountains as in the accompanying photograph. Identified features of the profile include the following: Head - the profile of Marble Mountain provides recognized facial features while a feathered headdress can be seen tapering north from Black Mountain and Marble Mountain.. Crossed Arms – Ute Peak is the highest, the most prominent and eastern-most peak in the Ute Mountains Ribcage – Horse Mountain to the east and the twin peaks Black Mountain/Ute Mountain to the west form a recognizable ribcage. Knees – Hermano Mountain or “The Knees” are the knees of the figure. Toes – East Toe is a small and prominent igneous protrusion at the south-eastern end of the Ute Mountains proportioned and placed to complete the figure from the east. West Toe, a second protrusion, has a similar profile and is placed to complete the figure from the west.
The illusion of a reclining figure is further reinforced by its symmetry. The figure is nearly as complete seen from the west as from the east.located east of cortez Though on the southwestern fringe of the original Rocky Mountain home of the Ute Tribe, the Sleeping Ute is the most prominent feature of the high-desert Ute Mountain Ute Reservation. The only town on the Reservation, lies at the feet of the figure and is home to most of the Reservation's population; as the Reservation capital, Towaoc is the Ute Mountain Ute tribal headquarters. Cortez, the largest town in the area with a population of over 8000, lies outside the reservation 11.5 miles east-northeast of Ute Peak. The elevation of Cortez can be considered the base elevation of the Ute Mountains; the Ute Mountain Ute Tribal Park adjoins Mesa Verde National Park to the east of the mountains. The western boundary of Mesa Verde National Park is 12 miles east of Ute Peak; the Mesa and the Sleeping Ute share equal prominence as regional landmarks.
McElmo Creek and Canyon Of The Ancients National Monument form the northern terminus of the Ute Mountains and the Reservation. The Ute Mountains were formed by intrusion of igneous rocks at about 72 million years, concurrent doming, subsequent erosion; the most common type of igneous rock is porphyritic hornblende diorite, but rock types present range from gabbro to granite. Forms of intrusions include laccoliths, stocks and sills. One dike can be examined at a roadside there; the igneous rocks intrude a sedimentary section of Jurassic and Cretaceous rocks and the youngest rocks intruded are in the Point Lookout Sandstone. The intrusions are similar in form and rock type to those in other Colorado Plateau mountain ranges, such as the Henry Mountains and the La Sal Range and the Abajo Mountains, all nearby in Utah, but the intrusions at these three Utah occurrences are about 20 to 30 million years in age; the Ute Mountains and the similar Carrizo Mountains, nearby in Arizona, lie within a southwest extension of the Colorado Mineral Belt, but no ore deposits are known to be associated with these igneous rocks.
Diorite is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar, hornblende, and/or pyroxene. The chemical composition of diorite is intermediate, between that of mafic gabbro and felsic granite. Diorite is grey to dark-grey in colour, but it can be black or bluish-grey, has a greenish cast, it is distinguished from gabbro on the basis of the composition of the plagioclase species. Diorite may contain small amounts of quartz and olivine. Zircon, titanite, magnetite and sulfides occur as accessory minerals. Minor amounts of muscovite may be present. Varieties deficient in hornblende and other dark minerals are called leucodiorite; when olivine and more iron-rich augite are present, the rock grades into ferrodiorite, transitional to gabbro. The presence of significant quartz makes the rock type quartz-diorite or tonalite, if orthoclase is present at greater than 10 percent, the rock type grades into monzodiorite or granodiorite. A dioritic rock containing feldspathoid mineral/s and no quartz is termed foid-bearing diorite or foid diorite according to content.
Diorite has a phaneritic speckled, texture of coarse grain size and is porphyritic. Orbicular diorite shows alternating concentric growth bands of plagioclase and amphibole surrounding a nucleus, within a diorite porphyry matrix. Diorites may be associated with either granite or gabbro intrusions, into which they may subtly merge. Diorite results from the partial melting of a mafic rock above a subduction zone, it is produced in volcanic arcs, in cordilleran mountain building, such as in the Andes Mountains, as large batholiths. The extrusive volcanic equivalent rock type is andesite. Diorite, although not rare, underlies comparatively small areas. An orbicular variety found in Corsica is called corsite. Diorite is an hard rock, making it difficult to carve and work with, its hardness, however allows it to be worked finely and take a high polish, to provide a durable finished work. One comparatively frequent use of diorite was for inscription, as it is easier to carve in relief than in three-dimensional statuary.
The most famous diorite work extant is the Code of Hammurabi, inscribed upon a 2.23 m pillar of black diorite. The original can be seen today in Paris' Musée du Louvre; the use of diorite in art was most important among early Middle Eastern civilizations such as Ancient Egypt, Babylonia and Sumer. It was so valued in early times that the first great Mesopotamian empire—the Empire of Sargon of Akkad—listed the taking of diorite as a purpose of military expeditions. Pallavas mamallapuram is one of the great example for diorite relief sculptures. Although one can find diorite art from periods, it became more popular as a structural stone and was used as pavement due to its durability. Diorite was used by both the Inca and Mayan civilizations, but for fortress walls, etc, it was popular with medieval Islamic builders. In times, diorite was used as cobblestone. Although diorite is rough-textured in nature, its ability to take a polish can be seen in the diorite steps of St. Paul's Cathedral, where centuries of foot traffic have polished the steps to a sheen.

The Colorado Plateau known as the Colorado Plateau Province, is a physiographic and desert region of the Intermontane Plateaus centered on the Four Corners region of the southwestern United States. This province covers an area of 336, 700 km2 within western Colorado, northwestern New Mexico and eastern Utah, northern Arizona. About 90% of the area is drained by the Colorado River and its main tributaries: the Green, San Juan, Little Colorado. Most of the remainder of the plateau is drained by its tributaries; the Colorado Plateau is made up of high desert, with scattered areas of forests. In the southwest corner of the Colorado Plateau lies the Grand Canyon of the Colorado River. Much of the Plateau's landscape is related, in both appearance and geologic history, to the Grand Canyon; the nickname "Red Rock Country" suggests the brightly colored rock left bare to the view by dryness and erosion. Domes, fins, river narrows, natural bridges, slot canyons are only some of the additional features typical of the Plateau.
The Colorado Plateau has the greatest concentration of U. S. National Park Service units in the country outside the Washington, DC metropolitan area. Among its nine National Parks are Grand Canyon, Bryce Canyon, Capitol Reef, Arches, Mesa Verde, Petrified Forest. Among its 18 National Monuments are Bears Ears, Rainbow Bridge, Hovenweep, Sunset Crater Volcano, Grand Staircase-Escalante, Natural Bridges, Canyons of the Ancients, Chaco Culture National Historical Park and the Colorado National Monument; this province is bounded by the Rocky Mountains in Colorado, by the Uinta Mountains and Wasatch Mountains branches of the Rockies in northern and central Utah. It is bounded by the Rio Grande Rift, Mogollon Rim and the Basin and Range Province. Isolated ranges of the Southern Rocky Mountains such as the San Juan Mountains in Colorado and the La Sal Mountains in Utah intermix into the central and southern parts of the Colorado Plateau, it is composed of six sections: Uinta Basin Section High Plateaus Section Grand Canyon Section Canyon Lands Section Navajo Section Datil SectionAs the name implies, the High Plateaus Section is, on average, the highest section.
North-south trending normal faults that include the Hurricane, Grand Wash, Paunsaugunt separate the section's component plateaus. This fault pattern is caused by the tensional forces pulling apart the adjacent Basin and Range province to the west, making this section transitional. Occupying the southeast corner of the Colorado Plateau is the Datil Section. Thick sequences of mid-Tertiary to late-Cenozoic-aged lava covers this section. Development of the province has in large part been influenced by structural features in its oldest rocks. Part of the Wasatch Line and its various faults form the western edge of the province. Faults that run parallel to the Wasatch Fault that lies along the Wasatch Range form the boundaries between the plateaus in the High Plateaus Section; the Uinta Basin, Uncompahgre Uplift, the Paradox Basin were created by movement along structural weaknesses in the region's oldest rock. In Utah, the province includes several higher fault-separated plateaus: Awapa Plateau Aquarius Plateau Kaiparowits Plateau Markagunt Plateau Paunsaugunt Plateau Sevier Plateau Fishlake Plateau Pavant Plateau Gunnison Plateau and the Tavaputs Plateau.
Some sources include the Tushar Mountain Plateau as part of the Colorado Plateau, but others do not. The flat-lying sedimentary rock units that make up these plateaus are found in component plateaus that are between 4,900 to 11,000 feet above sea level. A supersequence of these rocks is exposed in the various cliffs and canyons that make up the Grand Staircase. Younger east-west trending escarpments of the Grand Staircase extend north of the Grand Canyon and are named for their color: Chocolate Cliffs, Vermillion Cliffs, White Cliffs, Gray Cliffs, the Pink Cliffs. Within these rocks are abundant mineral resources that include uranium, coal and natural gas. Study of the area's unusually clear geologic history has advanced that science. A rain shadow from the Sierra Nevada far to the west and the many ranges of the Basin and Range means that the Colorado Plateau receives six to sixteen inches of annual precipitation. Higher areas receive more precipitation and are covered in forests of pine and spruce.
Though it can be said that the Plateau centers on the Four Corners, Black Mesa in northern Arizona is much closer to the east-west, north-south midpoint of the Plateau Province. Lying southeast of Glen Canyon and southwest of Monument Valley at the north end of the Hopi Reservation, this remote coal-laden highland has about half of the Colorado Plateau's acreage north of it, half south of it, half west of it, half east of it; the Ancestral Puebloan People lived in the region from 2000 to 700 years ago. A party from Santa Fe led by Fathers Dominguez and Escalante, unsuccessfully seeking an overland route to California, made a five-month out-and-back trip through much of the Plateau in 1776-1777. Despite having lost one arm in the American Civil War, U. S. Army Major and geologist John Wesley Powell explored the area in 1869 and 1872. Using wooden oak boats and small groups of men the Powell Geographic Expedition charted this unknown region of the United States for the federal government. Construction of the Hoover Dam in the 1930s and the Glen Canyon Dam in the 1960s changed the character of the Colorado River.

A mountain range or hill range is a series of mountains or hills ranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form and alignment that have arisen from the same cause an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are found on many planetary mass objects in the Solar System and are a feature of most terrestrial planets. Mountain ranges are segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not have the same geologic structure or petrology, they may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, volcanic landforms resulting in a variety of rock types. Most geologically young mountain ranges on the Earth's land surface are associated with either the Pacific Ring of Fire or the Alpide Belt.
The Pacific Ring of Fire includes the Andes of South America, extends through the North American Cordillera along the Pacific Coast, the Aleutian Range, on through Kamchatka, Taiwan, the Philippines, Papua New Guinea, to New Zealand. The Andes is 7,000 kilometres long and is considered the world's longest mountain system; the Alpide belt includes Indonesia and Southeast Asia, through the Himalaya, Caucasus Mountains, Balkan Mountains fold mountain range, the Alps, ends in the Spanish mountains and the Atlas Mountains. The belt includes other European and Asian mountain ranges; the Himalayas contain the highest mountains in the world, including Mount Everest, 8,848 metres high and traverses the border between China and Nepal. Mountain ranges outside these two systems include the Arctic Cordillera, the Urals, the Appalachians, the Scandinavian Mountains, the Great Dividing Range, the Altai Mountains and the Hijaz Mountains. If the definition of a mountain range is stretched to include underwater mountains the Ocean Ridges form the longest continuous mountain system on Earth, with a length of 65,000 kilometres.
The mountain systems of the earth are characterized by a tree structure, where mountain ranges can contain sub-ranges. The sub-range relationship is expressed as a parent-child relationship. For example, the White Mountains of New Hampshire and the Blue Ridge Mountains are sub-ranges of the Appalachian Mountains. Equivalently, the Appalachians are the parent of the White Mountains and Blue Ridge Mountains, the White Mountains and the Blue Ridge Mountains are children of the Appalachians; the parent-child expression extends to the sub-ranges themselves: the Sandwich Range and the Presidential Range are children of the White Mountains, while the Presidential Range is parent to the Northern Presidential Range and Southern Presidential Range. The position of mountains influences climate, such as snow; when air masses move up and over mountains, the air cools producing orographic precipitation. As the air descends on the leeward side, it warms again and is drier, having been stripped of much of its moisture.
A rain shadow will affect the leeward side of a range. Mountain ranges are subjected to erosional forces which work to tear them down; the basins adjacent to an eroding mountain range are filled with sediments which are buried and turned into sedimentary rock. Erosion is at work while the mountains are being uplifted until the mountains are reduced to low hills and plains; the early Cenozoic uplift of the Rocky Mountains of Colorado provides an example. As the uplift was occurring some 10,000 feet of Mesozoic sedimentary strata were removed by erosion over the core of the mountain range and spread as sand and clays across the Great Plains to the east; this mass of rock was removed as the range was undergoing uplift. The removal of such a mass from the core of the range most caused further uplift as the region adjusted isostatically in response to the removed weight. Rivers are traditionally believed to be the principal cause of mountain range erosion, by cutting into bedrock and transporting sediment.
Computer simulation has shown that as mountain belts change from tectonically active to inactive, the rate of erosion drops because there are fewer abrasive particles in the water and fewer landslides. Mountains on other planets and natural satellites of the Solar System are isolated and formed by processes such as impacts, though there are examples of mountain ranges somewhat similar to those on Earth. Saturn's moon Titan and Pluto, in particular exhibit large mountain ranges in chains composed of ices rather than rock. Examples include the Mithrim Montes and Doom Mons on Titan, Tenzing Montes and Hillary Montes on Pluto; some terrestrial planets other than Earth exhibit rocky mountain ranges, such as Maxwell Montes on Venus taller than any on Earth and Tartarus Montes on Mars, Jupiter's moon Io has mountain ranges formed from tectonic processes including Boösaule Montes, Dorian Montes, Hi'iaka Montes and Euboea Montes.
