Summit
–
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. Mathematically, a summit is a maximum in elevation. The topographic terms acme, apex, peak, and zenith are synonymous, the UIAA definition is that a summit is independent if it has a prominence of 30 metres or more, it is a mountain if it has a prominence of at least 300 metres. This can be summarised as follows, A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top, Summit may also refer to the highest point along a line, trail, or route. In many parts of the western United States, the term refers to the highest point along a road, highway. For example, the highest point along Interstate 80 in California is referred to as Donner Summit while the highest point on Interstate 5 is Siskiyou Mountain Summit, geoid Hill List of highest mountains Maxima and minima Nadir Summit accordance Peak finder

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located 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, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Texas
–
Texas is the second largest state in the United States by both area and population. Other major cities include Austin, the second most populous state capital in the U. S. Texas is nicknamed the Lone Star State to signify its former status as an independent republic, and as a reminder of the states struggle for independence from Mexico. The Lone Star can be found on the Texan state flag, the origin of Texass name is from the word Tejas, which means friends in the Caddo language. Due to its size and geologic features such as the Balcones Fault, although Texas is popularly associated with the U. S. southwestern deserts, less than 10 percent of Texas land area is desert. Most of the centers are located in areas of former prairies, grasslands, forests. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, the term six flags over Texas refers to several nations that have ruled over the territory. Spain was the first European country to claim the area of Texas, Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the United States as the 28th state, the states annexation set off a chain of events that caused the Mexican–American War in 1846. A slave state before the American Civil War, Texas declared its secession from the U. S. in early 1861, after the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation. One Texan industry that thrived after the Civil War was cattle, due to its long history as a center of the industry, Texas is associated with the image of the cowboy. The states economic fortunes changed in the early 20th century, when oil discoveries initiated a boom in the state. With strong investments in universities, Texas developed a diversified economy, as of 2010 it shares the top of the list of the most Fortune 500 companies with California at 57. With a growing base of industry, the leads in many industries, including agriculture, petrochemicals, energy, computers and electronics, aerospace. Texas has led the nation in export revenue since 2002 and has the second-highest gross state product. The name Texas, based on the Caddo word tejas meaning friends or allies, was applied by the Spanish to the Caddo themselves, during Spanish colonial rule, the area was officially known as the Nuevo Reino de Filipinas, La Provincia de Texas. Texas is the second largest U. S. state, behind Alaska, though 10 percent larger than France and almost twice as large as Germany or Japan, it ranks only 27th worldwide amongst country subdivisions by size. If it were an independent country, Texas would be the 40th largest behind Chile, Texas is in the south central part of the United States of America. Three of its borders are defined by rivers, the Rio Grande forms a natural border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south

New Mexico
–
New Mexico is a state located in the southwestern region of the United States of America. It was admitted to the Union as the 47th state on January 6,1912 and it is usually considered one of the Mountain States. New Mexico is fifth by area, the 36th-most populous, inhabited by Native Americans for thousands of years before European exploration, New Mexico was colonized by the Spanish in 1598 Imperial Spanish viceroyalty of New Spain. Later, it was part of independent Mexico before becoming a U. S. territory and eventually a U. S. state as a result of the Mexican–American War. Among U. S. states, New Mexico has the highest percentage of Hispanics, the major Native American nations in the state are Navajo, Pueblo, and Apache peoples. The demography and culture of the state are shaped by these strong Hispanic and Native American influences and its scarlet and gold colors are taken from the royal standards of Spain, along with the ancient sun symbol of the Zia, a Pueblo-related tribe. New Mexico, or Nuevo México in Spanish, is incorrectly believed to have taken its name from the nation of Mexico. The name simply stuck, even though the area had no connection to Mexico or the Mexica Indian tribes, Mexico, formerly a part of New Spain, adopted its name centuries later in 1821, after winning independence from Spanish rule. New Mexico was a part of the independent Mexican Empire and Federal Republic of Mexico for 27 years,1821 through 1848, New Mexico and Mexico developed as neighboring Spanish-speaking communities under Spanish rule, with relatively independent histories. The states total area is 121,412 square miles, the eastern border of New Mexico lies along 103° W longitude with the state of Oklahoma, and 2.2 miles west of 103° W longitude with Texas. On the southern border, Texas makes up the eastern two-thirds, while the Mexican states of Chihuahua and Sonora make up the western third, the western border with Arizona runs along the 109°03 W longitude. The southwestern corner of the state is known as the Bootheel, the 37° N latitude parallel forms the northern boundary with Colorado. The states New Mexico, Colorado, Arizona, and Utah come together at the Four Corners in the corner of New Mexico. New Mexico, although a state, has very little water. Its surface water area is about 250 square miles, the New Mexican landscape ranges from wide, rose-colored deserts to broken mesas to high, snow-capped peaks. Despite New Mexicos arid image, heavily forested mountain wildernesses cover a significant portion of the state, the Sangre de Cristo Mountains, the southernmost part of the Rocky Mountains, run roughly north-south along the east side of the Rio Grande in the rugged, pastoral north. The most important of New Mexicos rivers are the Rio Grande, Pecos, Canadian, San Juan, the Rio Grande is tied for the fourth-longest river in the United States. Tourists visiting these sites bring significant money to the state, other areas of geographical and scenic interest include Kasha-Katuwe Tent Rocks National Monument and the Gila Wilderness in the southwest of the state

El Paso, Texas
–
El Paso is the seat of El Paso County, Texas, United States. The city is situated in the far corner of the U. S. state of Texas. El Paso stands on the Rio Grande river across the Mexico–United States border from Ciudad Juárez, the region of over 2.9 million people constitutes the largest bilingual and binational work force in the Western Hemisphere. The city hosts the annual Sun Bowl college football post-season game, El Paso has a strong federal and military presence. William Beaumont Army Medical Center, Biggs Army Airfield, and Fort Bliss call the city home, Fort Bliss is one of the largest military complexes of the United States Army and the largest training area in the United States. Also headquartered in El Paso are the DEA domestic field division 7, El Paso Intelligence Center, Joint Task Force North, Border Patrol El Paso Sector, and U. S. In 2010, El Paso received an All-America City Award, El Paso has been ranked the safest large city in the U. S. for four consecutive years and has ranked in the top three since 1997. As of July 1,2015, the estimate for the city from the U. S. Census was 681,124. Its U. S. metropolitan area covers all of El Paso and Hudspeth counties in Texas, the El Paso MSA forms part of the larger El Paso–Las Cruces CSA, with a population of 1,053,267. The El Paso region has had human settlement for thousands of years, the evidence suggests 10,000 to 12,000 years of human habitation. The earliest known cultures in the region were maize farmers, when the Spanish arrived, the Manso, Suma, and Jumano tribes populated the area. These were subsequently incorporated into the Mestizo culture, along with immigrants from central Mexico, captives from Comanchería, the Mescalero Apache were also present. El Paso del Norte was founded on the bank of the Río Bravo del Norte. El Paso remained the largest settlement in New Mexico until its cession to the U. S. in 1848, the Texas Revolution was generally not felt in the region, as the American population was small, not being more than 10% of the population. However, the region was claimed by Texas as part of the treaty signed with Mexico, during this interregnum, 1836–1848, Americans nonetheless continued to settle the region. The present Texas–New Mexico boundary placing El Paso on the Texas side was drawn in the Compromise of 1850, El Paso County was established in March 1850, with San Elizario as the first county seat. The United States Senate fixed a boundary between Texas and New Mexico at the 32nd parallel, thus largely ignoring history and topography, a military post called The Post opposite El Paso was established in 1854. Further west, a settlement on Coons Rancho called Franklin became the nucleus of the future El Paso, a year later, pioneer Anson Mills completed his plan of the town, calling it El Paso

Franklin Mountains (Texas)
–
The Franklin Mountains of Texas are a small range that extend from El Paso, Texas north into New Mexico. The Franklins were formed due to crustal extension related to the Cenozoic Rio Grande rift, the highest peak is North Franklin Peak at 7,192 feet. Much of the range is part of the Franklin Mountains State Park, the mountains are composed primarily of sedimentary rock with some igneous intrusions. Geologists refer to them as tilted-block fault mountains and in them can be found 1.25 billion-year-old Precambrian rocks, trans-Pecos Chihuahuan Desert Davis Mountains Guadalupe Mountains McKittrick Canyon El Paso, Texas Beach Mountains Franklin Mountains from the Handbook of Texas Online

Rocky Mountains
–
The Rocky Mountains, commonly known as the Rockies, are a major mountain range in western North America. The Rocky Mountains stretch more than 3,000 miles from the northernmost part of British Columbia, in western Canada, to New Mexico, in the Southwestern United States. Within the North American Cordillera, the Rockies are somewhat distinct from the Pacific Coast Ranges, the Rocky Mountains were initially formed from 80 million to 55 million years ago during the Laramide orogeny, in which a number of plates began to slide underneath the North American plate. The angle of subduction was shallow, resulting in a belt of mountains running down western North America. Since then, further tectonic activity and erosion by glaciers have sculpted the Rockies into dramatic peaks, at the end of the last ice age, humans started to inhabit the mountain range. The first mention of their present name by a European was in the journal of Jacques Legardeur de Saint-Pierre in 1752, the Rocky Mountains are commonly defined as stretching from the Liard River in British Columbia south to the Rio Grande in New Mexico. The United States definition of the Rockies includes the Cabinet and Salish Mountains of Idaho and their counterparts north of the Kootenai River, the Columbia Mountains, are considered a separate system in Canada, lying to the west of the huge Rocky Mountain Trench. This runs the length of British Columbia from its beginnings in the middle Flathead River valley in western Montana to the bank of the Liard River. The Rockies vary in width from 70 to 300 miles, also west of the Rocky Mountain Trench, farther north and facing the Muskwa Range across the trench, are the Stikine Ranges and Omineca Mountains of the Interior Mountains system of British Columbia. A small area east of Prince George, British Columbia on the side of the Trench. In Canada geographers define three main groups of ranges, the Continental Ranges, Hart Ranges and Muskwa Ranges, the Muskwa and Hart Ranges together comprise what is known as the Northern Rockies. The western edge of the Rockies includes ranges such as the Wasatch near Salt Lake City, the Great Basin and Columbia River Plateau separate these sub-ranges from distinct ranges further to the west, most prominent among which are the Sierra Nevada, Cascade Range and Coast Mountains. The Rocky Mountain System within the United States is a United States physiographic region, the Rocky Mountains are notable for containing the highest peaks in central North America. The ranges highest peak is Mount Elbert located in Colorado at 14,440 feet above sea level, Mount Robson in British Columbia, at 12,972 feet, is the highest peak in the Canadian Rockies. The Continental Divide of the Americas is located in the Rocky Mountains, triple Divide Peak in Glacier National Park is so named because water that falls on the mountain reaches not only the Atlantic and Pacific, but Hudson Bay as well. Farther north in Alberta, the Athabasca and other rivers feed the basin of the Mackenzie River, see Rivers of the Rocky Mountains for a list of rivers. Human population is not very dense in the Rocky Mountains, with an average of four people per square kilometer, however, the human population grew rapidly in the Rocky Mountain states between 1950 and 1990. The 40-year statewide increases in range from 35% in Montana to about 150% in Utah

Cretaceous
–
The Cretaceous is a geologic period and system that spans 79 million years from the end of the Jurassic Period 145 million years ago to the beginning of the Paleogene Period 66 Mya. It is the last period of the Mesozoic Era, the Cretaceous Period is usually abbreviated K, for its German translation Kreide. The Cretaceous was a period with a warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites and rudists, during this time, new groups of mammals and birds, as well as flowering plants, appeared. The Cretaceous ended with a mass extinction, the Cretaceous–Paleogene extinction event, in which many groups, including non-avian dinosaurs, pterosaurs. The end of the Cretaceous is defined by the abrupt Cretaceous–Paleogene boundary, the name Cretaceous was derived from Latin creta, meaning chalk. The Cretaceous is divided into Early and Late Cretaceous epochs, or Lower and Upper Cretaceous series, in older literature the Cretaceous is sometimes divided into three series, Neocomian, Gallic and Senonian. A subdivision in eleven stages, all originating from European stratigraphy, is now used worldwide, in many parts of the world, alternative local subdivisions are still in use. As with other geologic periods, the rock beds of the Cretaceous are well identified. No great extinction or burst of diversity separates the Cretaceous from the Jurassic and this layer has been dated at 66.043 Ma. A140 Ma age for the Jurassic-Cretaceous boundary instead of the usually accepted 145 Ma was proposed in 2014 based on a study of Vaca Muerta Formation in Neuquén Basin. Víctor Ramos, one of the authors of the study proposing the 140 Ma boundary age sees the study as a first step toward formally changing the age in the International Union of Geological Sciences, due to the high sea level there was extensive space for such sedimentation. Because of the young age and great thickness of the system. Chalk is a type characteristic for the Cretaceous. It consists of coccoliths, microscopically small calcite skeletons of coccolithophores, the group is found in England, northern France, the low countries, northern Germany, Denmark and in the subsurface of the southern part of the North Sea. Chalk is not easily consolidated and the Chalk Group still consists of sediments in many places. The group also has other limestones and arenites, among the fossils it contains are sea urchins, belemnites, ammonites and sea reptiles such as Mosasaurus. In southern Europe, the Cretaceous is usually a marine system consisting of competent limestone beds or incompetent marls

United States Geological Survey
–
The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its resources. The organization has four science disciplines, concerning biology, geography, geology. The USGS is a research organization with no regulatory responsibility. The USGS is a bureau of the United States Department of the Interior, the USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, the current motto of the USGS, in use since August 1997, is science for a changing world. The agencys previous slogan, adopted on the occasion of its anniversary, was Earth Science in the Public Service. Prompted by a report from the National Academy of Sciences, the USGS was created, by a last-minute amendment and it was charged with the classification of the public lands, and examination of the geological structure, mineral resources, and products of the national domain. This task was driven by the need to inventory the vast lands added to the United States by the Louisiana Purchase in 1803, the legislation also provided that the Hayden, Powell, and Wheeler surveys be discontinued as of June 30,1879. Clarence King, the first director of USGS, assembled the new organization from disparate regional survey agencies, after a short tenure, King was succeeded in the directors chair by John Wesley Powell. Administratively, it is divided into a Headquarters unit and six Regional Units, Other specific programs include, Earthquake Hazards Program monitors earthquake activity worldwide. The National Earthquake Information Center in Golden, Colorado on the campus of the Colorado School of Mines detects the location, the USGS also runs or supports several regional monitoring networks in the United States under the umbrella of the Advanced National Seismic System. The USGS informs authorities, emergency responders, the media, and it also maintains long-term archives of earthquake data for scientific and engineering research. It also conducts and supports research on long-term seismic hazards, USGS has released the UCERF California earthquake forecast. The USGS National Geomagnetism Program monitors the magnetic field at magnetic observatories and distributes magnetometer data in real time, the USGS operates the streamgaging network for the United States, with over 7400 streamgages. Real-time streamflow data are available online, since 1962, the Astrogeology Research Program has been involved in global, lunar, and planetary exploration and mapping. USGS operates a number of related programs, notably the National Streamflow Information Program. USGS Water data is available from their National Water Information System database

Magdalena Mountains
–
The Magdalena Mountains are a regionally high, mountain range in Socorro County, in west-central New Mexico in the southwestern United States. The highest point in the range is South Baldy, at 10,783 ft, the range runs roughly north-south and is about 18 miles long. The range lies just south of the village of Magdalena, the Magdalena Mountains are an east-tilted fault-block range, superimposed on Cenozoic calderas. The complex geologic history of the range has resulted in spectacular scenery, with unusual and they form part of the western edge of the Rio Grande Rift Valley, fronting the La Jencia Basin. The mountains remain isolated and natural due to the absence of any significant human development within or near the range, the range takes its name from a volcanic peak on the west side, named Magdalena Peak, after Mary Magdalene. A talus formation and shrub growth on the east slope of Magdalena Peak is said to resemble a womans face. ”Most of the Magdalena Mountains are within the Magdalena Ranger District of the Cibola National Forest, and parts are also administered by the Bureau of Land Management. While there are no designated Wilderness areas in the range, the Ryan Hill Inventoried Roadless Area is sizeable, in 1980, Public Law 96-550 established Langmuir Research Site in the Magdalena Mountains. Congress found the mountains uniquely suited for atmospheric and astronomical research which has conducted at Langmuir Laboratory near South Baldy since the mid-1960s. The Act designated a 31,000 acre portion of the mountain as essentially roadless, there is overlap between the Ryan Hill IRA and the congressionally designated Langmuir Research Site management area. Directly adjacent to the boundary of the Ryan Hill IRA lies the Devil’s Reach Wilderness Study Area. The Devils Reach WSA and its neighboring Devil’s Backbone WSA are both managed by the BLM, the Ryan Hill IRA, Devils Reach WSA, and Devils Backbone WSA combine to form a 44, 050-acre contiguous roadless area on the southern end of the range. A well-established network of trails exists in the Magdalena Mountains, providing adundant hiking, backpacking, hunting, horseback-riding, the Forest Service notes that there are over 60 miles of trails in the Magdalenas. Over half of the trails are in the Ryan Hill Inventoried Roadless Area, the Water Canyon Campground is a developed campsite located at 6,800 ft elevation in the Magdalenas. Visiting scientists at Langmuir also study bats, hummingbirds, butterflies, the same area hosts the Magdalena Ridge Observatory Interferometer, also operated by New Mexico Tech, along with other institutions. The history of the Magdalena Mountains is intimately linked with the history of the surrounding area. Bands of Apache effectively controlled the Magdalena-Datil region from the century until they were defeated in the Apache Wars in the late nineteenth century. A mining rush followed the Apache wars – gold, silver, in fact, the last regularly used cattle trail in the United States stretched 125 miles westward from Magdalena. The route was known as the Magdalena Livestock Driveway, but more popularly known to cowboys

Organ Mountains (New Mexico)
–
The Organ Mountains are a rugged mountain range in southern New Mexico in the Southwestern United States. Organ Mountains-Desert Peaks National Monument was declared a monument on May 21,2014. They lie 10 miles east of the city of Las Cruces, the Organ Mountains are near the southern end of a long line of mountains on the east side of the Rio Grandes rift valley. The range is contiguous with the San Andres Mountains to the north and the Franklin Mountains to the south. Whereas the San Andres and Franklin Mountains are both formed from west-dipping fault blocks of sedimentary strata, the Organ Mountains are made primarily of igneous rock. Their name reflects their similarity in appearance with pipes that would be part of a pipe organ, the Franklin Mountains are separated from the Organ Mountains by a 10-mile wide low area known as Anthony Gap. Much of this land is part of Fort Bliss. The Organ Mountains are made up of three sections, On the north end is a narrow ridge of vertically-jointed Tertiary granite called The Needles. This is the most picturesque section and includes the highest point in the range, on the south side of The Needles is a much wider section of extrusive igneous rock, mostly a purplish-gray rhyolite. This section forms the bulk of the range and reaches heights nearly as great as The Needles. This section is cut in half by Soledad Canyon, which extends west from the east side of the range, separated by a low ridge and Soledad Pass from Bar Canyon on the west side. The third portion of the Organ Mountains consists of the Bishops Cap Hills on the southwest side of the range and Rattlesnake Ridge on the southeast side of the range. This third section is much smaller and lower in elevation than the sections of the range. The Organ Mountains may be the most botanically diverse mountain range in New Mexico, several of these, including the Organ Mountains evening-primrose and smooth figwort, are endemic to the mountain range and occur only in small, scattered populations. The Organ Mountains also have surprisingly high diversity in ferns, with 30 of the 56 species reported for New Mexico occurring within it. The high diversity and endemism of the range makes the Organ Mountains a very rewarding destination for the botanically-inclined, the flora differs greatly between the three sections of the mountain range, with the two igneous sections sharing relatively few species with the southern limestone portions. The first documented climbs of Organ Mountain peaks were in the early 1890s, the most prominent of these was R. L Ingraham, whose Guide to Climbing in the Organ Mountains remains a definitive reference. Technical climbing began only in the late 1940s, with some ascents by a group of German rocket scientists brought here to work at the White Sands Proving Grounds directly after the fall of Germany

A paved road spirals around the volcano and visitors can drive up to a parking lot at the rim. Hiking trails circle the rim as well as lead down into the mouth of the volcano, the monument was designated on August 9,1916 and is administered by the National Park Service. The visitor center features exhibits about the volcano and the geology, natural and cultural history. There is also a presentation about the volcano. The name capulin comes from a type of cherry, Prunus serotina. National Monument by Presidential Proclamation No, on December 31,1987, Congress changed the Monuments name from Capulin Mountain National Monument to Capulin Volcano National Monument by Public Law 100-225.
