Colorado
Colorado is a state of the Western United States encompassing most of the southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. It is the 8th most extensive and 21st most populous U. S. state. The estimated population of Colorado was 5,695,564 on July 1, 2018, an increase of 13.25% since the 2010 United States Census. The state was named for the Colorado River, which early Spanish explorers named the Río Colorado for the ruddy silt the river carried from the mountains; the Territory of Colorado was organized on February 28, 1861, on August 1, 1876, U. S. President Ulysses S. Grant signed Proclamation 230 admitting Colorado to the Union as the 38th state. Colorado is nicknamed the "Centennial State" because it became a state one century after the signing of the United States Declaration of Independence. Colorado is bordered by Wyoming to the north, Nebraska to the northeast, Kansas to the east, Oklahoma to the southeast, New Mexico to the south, Utah to the west, touches Arizona to the southwest at the Four Corners.
Colorado is noted for its vivid landscape of mountains, high plains, canyons, plateaus and desert lands. Colorado is part of the western and southwestern United States, is one of the Mountain States. Denver is most populous city of Colorado. Residents of the state are known as Coloradans, although the antiquated term "Coloradoan" is used. Colorado is notable for its diverse geography, which includes alpine mountains, high plains, deserts with huge sand dunes, deep canyons. In 1861, the United States Congress defined the boundaries of the new Territory of Colorado by lines of latitude and longitude, stretching from 37°N to 41°N latitude, from 102°02'48"W to 109°02'48"W longitude. After 158 years of government surveys, the borders of Colorado are now defined by 697 boundary markers and 697 straight boundary lines. Colorado and Utah are the only states that have their borders defined by straight boundary lines with no natural features; the southwest corner of Colorado is the Four Corners Monument at 36°59'56"N, 109°2'43"W.
This is the only place in the United States where four states meet: Colorado, New Mexico and Utah. The summit of Mount Elbert at 14,440 feet elevation in Lake County is the highest point in Colorado and the Rocky Mountains of North America. Colorado is the only U. S. state that lies above 1,000 meters elevation. The point where the Arikaree River flows out of Yuma County and into Cheyenne County, Kansas, is the lowest point in Colorado at 3,317 feet elevation; this point, which holds the distinction of being the highest low elevation point of any state, is higher than the high elevation points of 18 states and the District of Columbia. A little less than half of Colorado is flat and rolling land. East of the Rocky Mountains are the Colorado Eastern Plains of the High Plains, the section of the Great Plains within Nebraska at elevations ranging from 3,350 to 7,500 feet; the Colorado plains are prairies but include deciduous forests and canyons. Precipitation averages 15 to 25 inches annually. Eastern Colorado is presently farmland and rangeland, along with small farming villages and towns.
Corn, hay and oats are all typical crops. Most villages and towns in this region boast both a grain elevator. Irrigation water is available from subterranean sources. Surface water sources include the South Platte, the Arkansas River, a few other streams. Subterranean water is accessed through artesian wells. Heavy use of wells for irrigation caused underground water reserves to decline. Eastern Colorado hosts considerable livestock, such as hog farms. 70% of Colorado's population resides along the eastern edge of the Rocky Mountains in the Front Range Urban Corridor between Cheyenne and Pueblo, Colorado. This region is protected from prevailing storms that blow in from the Pacific Ocean region by the high Rockies in the middle of Colorado; the "Front Range" includes Denver, Fort Collins, Castle Rock, Colorado Springs, Pueblo and other townships and municipalities in between. On the other side of the Rockies, the significant population centers in Western Colorado are the cities of Grand Junction and Montrose.
The Continental Divide of the Americas extends along the crest of the Rocky Mountains. The area of Colorado to the west of the Continental Divide is called the Western Slope of Colorado. West of the Continental Divide, water flows to the southwest via the Colorado River and the Green River into the Gulf of California. Within the interior of the Rocky Mountains are several large parks which are high broad basins. In the north, on the east side of the Continental Divide is the North Park of Colorado; the North Park is drained by the North Platte River, which flows north into Nebraska. Just to the south of North Park, but on the western side of the Continental Divide, is the Middle Park of Colorado, drained by the Colorado River; the South Park of Colorado is the region of the headwaters of the South Platte River. In southmost Colorado is the large San Luis Valley, where the headwaters of the Rio Grande are located; the valley sits between the Sangre De Cristo Mountains and San Juan Mountains, consists of large desert lands that run into the mountains.
The Rio Grande drains due south into New Mexico and Texas. Across the Sangre de Cristo Range to the east of the S
San Miguel River (Colorado)
The San Miguel River is a tributary of the Dolores River 81 miles long, in southwestern Colorado in the United States. It rises in the San Juan Mountains southeast of Telluride and flows northwest, along the southern slope of the Uncompahgre Plateau, past the towns of Placerville and Nucla and joins the Dolores in western Montrose County 15 miles east of the state line with Utah; the San Miguel is less free flowing. The San Miguel varies in gradient, from steep in its upper reaches to more mellow in the lower sections. All told, the San Miguel drops over 7,000 feet from an alpine ecosystem to the desert; the average flow is about 600 cu ft/s. Whitewater kayakers and boaters enjoy many sections on the San Miguel. Minimum suggested flows for small vessels is 250 cfs, with the river near Placerville becoming navigable in late April or early May. Several runs of varying length are undertaken from there to the confluence with the Dolores, near the site of Uravan; the San Miguel is considered a continuous class 2 run with several class three rapids which become more challenging at higher flows, where the river's speed can make it difficult to stop and scout.
Additional River hazards are three diversion dams that exist between Naturita and the Hwy 145 bridge East of Norwood. All of them are easy to scout and portage, however; as the river meanders through an agricultural valley just East of Naturita, several cattle fences cross the river.

Colorado Plateau
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.

Jurassic
The Jurassic period was a geologic period and system that spanned 56 million years from the end of the Triassic Period 201.3 million years ago to the beginning of the Cretaceous Period 145 Mya. The Jurassic constitutes the middle period of the Mesozoic Era known as the Age of Reptiles; the start of the period was marked by the major Triassic–Jurassic extinction event. Two other extinction events occurred during the period: the Pliensbachian-Toarcian extinction in the Early Jurassic, the Tithonian event at the end; the Jurassic period is divided into three epochs: Early and Late. In stratigraphy, the Jurassic is divided into the Lower Jurassic, Middle Jurassic, Upper Jurassic series of rock formations; the Jurassic is named after the Jura Mountains within the European Alps, where limestone strata from the period were first identified. By the beginning of the Jurassic, the supercontinent Pangaea had begun rifting into two landmasses: Laurasia to the north, Gondwana to the south; this created more coastlines and shifted the continental climate from dry to humid, many of the arid deserts of the Triassic were replaced by lush rainforests.
On land, the fauna transitioned from the Triassic fauna, dominated by both dinosauromorph and crocodylomorph archosaurs, to one dominated by dinosaurs alone. The first birds appeared during the Jurassic, having evolved from a branch of theropod dinosaurs. Other major events include the appearance of the earliest lizards, the evolution of therian mammals, including primitive placentals. Crocodilians made the transition from a terrestrial to an aquatic mode of life; the oceans were inhabited by marine reptiles such as ichthyosaurs and plesiosaurs, while pterosaurs were the dominant flying vertebrates. The chronostratigraphic term "Jurassic" is directly linked to the Jura Mountains, a mountain range following the course of the France–Switzerland border. During a tour of the region in 1795, Alexander von Humboldt recognized the limestone dominated mountain range of the Jura Mountains as a separate formation that had not been included in the established stratigraphic system defined by Abraham Gottlob Werner, he named it "Jura-Kalkstein" in 1799.
The name "Jura" is derived from the Celtic root *jor via Gaulish *iuris "wooded mountain", borrowed into Latin as a place name, evolved into Juria and Jura. The Jurassic period is divided into three epochs: Early and Late. In stratigraphy, the Jurassic is divided into the Lower Jurassic, Middle Jurassic, Upper Jurassic series of rock formations known as Lias and Malm in Europe; the separation of the term Jurassic into three sections originated with Leopold von Buch. The faunal stages from youngest to oldest are: During the early Jurassic period, the supercontinent Pangaea broke up into the northern supercontinent Laurasia and the southern supercontinent Gondwana; the Jurassic North Atlantic Ocean was narrow, while the South Atlantic did not open until the following Cretaceous period, when Gondwana itself rifted apart. The Tethys Sea closed, the Neotethys basin appeared. Climates were warm, with no evidence of a glacier having appeared; as in the Triassic, there was no land over either pole, no extensive ice caps existed.
The Jurassic geological record is good in western Europe, where extensive marine sequences indicate a time when much of that future landmass was submerged under shallow tropical seas. In contrast, the North American Jurassic record is the poorest of the Mesozoic, with few outcrops at the surface. Though the epicontinental Sundance Sea left marine deposits in parts of the northern plains of the United States and Canada during the late Jurassic, most exposed sediments from this period are continental, such as the alluvial deposits of the Morrison Formation; the Jurassic was a time of calcite sea geochemistry in which low-magnesium calcite was the primary inorganic marine precipitate of calcium carbonate. Carbonate hardgrounds were thus common, along with calcitic ooids, calcitic cements, invertebrate faunas with dominantly calcitic skeletons; the first of several massive batholiths were emplaced in the northern American cordillera beginning in the mid-Jurassic, marking the Nevadan orogeny. Important Jurassic exposures are found in Russia, South America, Japan and the United Kingdom.
In Africa, Early Jurassic strata are distributed in a similar fashion to Late Triassic beds, with more common outcrops in the south and less common fossil beds which are predominated by tracks to the north. As the Jurassic proceeded and more iconic groups of dinosaurs like sauropods and ornithopods proliferated in Africa. Middle Jurassic strata are neither well studied in Africa. Late Jurassic strata are poorly represented apart from the spectacular Tendaguru fauna in Tanzania; the Late Jurassic life of Tendaguru is similar to that found in western North America's Morrison Formation. During the Jurassic period, the primary vertebrates living in the sea were marine reptiles; the latter include ichthyosaurs, which were at the peak of their diversity, plesiosaurs and marine crocodiles of the families Teleosauridae and Metriorhynchidae. Numerous turtles could be found in rivers. In the invertebrate world, several new groups appeared, including rudists (a reef-formi
Entrada Sandstone
The Entrada Sandstone is a formation in the San Rafael Group, found in the U. S. states of Wyoming, northwest New Mexico, northeast Arizona and southeast Utah. Part of the Colorado Plateau, this formation was deposited during the Jurassic period sometime between 180 and 140 million years ago in various environments, including tidal mudflats and sand dunes; the Middle Jurassic San Rafael Group was dominantly deposited as ergs in a desert environment around the shallow Sundance Sea. This formation has been dated to the early to middle Callovian stage of the latest Middle Jurassic; the type locality and place for which the unit is named is Entrada Point, located in the northern part the San Rafael Swell in Emery County, Utah. The Entrada Sandstone was named as one of the four formations of the San Rafael Group by James Gilluly and Reeside in 1928. In the 1928 description, the Entrada is overlain by the Curtis Formation, overlies the Carmel Formation. In the Curtis Mountains region of northeastern Arizona, the Entrada is overlain by the Wanakah Formation.
Gregory and Moore worked out the geographic extent of the formation and gave an overview of it in 1931. The extent was revised several times afterwards, it was divided into the Gunsight Butte and Escalante members by Thompson and Stokes in 1970. The principal reference for the formation was written in 1988 by Peterson. Entrada members are: Cannonville Member, Cow Springs Member, Dewey Bridge Member - named after the type locality at Dewey Bridge; this brick-red layer has a blocky look to it. Escalante Member, Henrieville Member, Exeter Member, Gunsight Butte Member, Iyanbito Member, Moab Member or Moab Tongue - named after the type locality of Moab, Utah; the whitish sands from inland dunes make up this "cap rock" layer, as seen atop Delicate Arch and Broken Arch in Arches National Park. Red Mesa Member, Slick Rock Member - named for the type locality at Colorado. Entrada Sandstone is found in these geologic locations:Geologic province: Anadarko Basin Black Mesa Basin Denver Basin Great Basin province Green River Basin Las Vegas-Raton Basin Paradox Basin Piceance Basin Plateau sedimentary province San Juan Basin Sierra Grande Uplift Found in these parklands: Arches National Park Capitol Reef National Park Goblin Valley State Park Kodachrome Basin State ParkSpatial distribution: spatial distribution of Entrada Sandstone in Macrostrat Condon, S.

Cisco, Utah
Cisco is a ghost town in Grand County, United States near the junction of State Route 128 and Interstate 70. The town started in the 1880s as a saloon and water-refilling station for the Denver and Rio Grande Western Railroad; as work crews and travelers came through, stores and restaurants sprang up to accommodate them. Nearby cattle ranchers and sheep herders in the Book Cliffs north of town began using Cisco as a livestock and provisioning center. Around the turn of the 20th century, over 100,000 sheep were sheared at Cisco before being shipped to market. After oil and natural gas were discovered, people began traveling more and Cisco continued to grow; the bottom fell out. The town's decline coincided with the demise of the steam locomotive. A declining economy crashed when Interstate 70 was built; the town site contains many relics of a typical old west railroad town. Cisco survived long enough into the 20th century to be assigned a ZIP Code, 84515. For history and railroad buffs, the ghost town's easy access and proximity to the freeway have lured vandals.
The relics are damaged and the town is littered with abandoned vehicles. Oil and natural gas were discovered near Cisco in 1924. In 2005, new oil and gas wells were drilled in the nearby Cisco Oil Field by a Reno, Nevada-based company. Newly drilled wells can be seen next around the freeway. Cisco Mayor Dan Vanover was an oil and turquoise miner from 1963 until his death in 1986, his home had a large flag pole in front of it. Cisco is along the former routing of US‑6/US‑50; the town was bypassed with the completion of I‑70 through the area but is still accessible by way of Exit 204. Cisco is listed as a control city for SR‑128. Cisco is still served by the Union Pacific Railroad; the California Zephyr passenger train is not a scheduled stop. During the summer months, whitewater river rafters use Cisco as a landing site for a trip through Westwater Canyon; the Kokopelli mountain bike Trail passes through Cisco. Johnny Cash wrote the song Cisco Clifton's Fillin Station about H. Ballard Harris, a man living in Cisco.
His wife was named Maxine Harris. They owned a gas station/curio shop. In the 1980s, they were in their 70s. "The Cisco Cliftons" band is composed of one of H. Ballard Harris's grandsons and was the inspiration for the band name. Cisco was a filming location for the movies Vanishing Point and Louise, Don't Come Knocking, it was filmed by the online group "The Creatures" during their "Road to E3" online special. According to the Köppen Climate Classification system, Cisco has a semi-arid climate, abbreviated "BSk" on climate maps. Ghosttowns.com Cisco Utah Cisco Photo tour
