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

Arizona
–
Arizona is a state in the southwestern region of the United States. It is also part of the Western United States and the Mountain West states and it is the sixth largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix, Arizona is one of the Four Corners states. It has borders with New Mexico, Utah, Nevada, California, and Mexico, Arizonas border with Mexico is 389 miles long, on the northern border of the Mexican states of Sonora and Baja California. Arizona is the 48th state and last of the states to be admitted to the Union. Historically part of the territory of Alta California in New Spain, after being defeated in the Mexican–American War, Mexico ceded much of this territory to the United States in 1848. The southernmost portion of the state was acquired in 1853 through the Gadsden Purchase, Southern Arizona is known for its desert climate, with very hot summers and mild winters. There are ski resorts in the areas of Flagstaff, Alpine, in addition to the Grand Canyon National Park, there are several national forests, national parks, and national monuments. To the European settlers, their pronunciation sounded like Arissona, the area is still known as alĭ ṣonak in the Oodham language. Another possible origin is the Basque phrase haritz ona, as there were numerous Basque sheepherders in the area, There is a misconception that the states name originated from the Spanish term Árida Zona. See also lists of counties, islands, rivers, lakes, state parks, national parks, Arizona is in the Southwestern United States as one of the Four Corners states. Arizona is the sixth largest state by area, ranked after New Mexico, of the states 113,998 square miles, approximately 15% is privately owned. The remaining area is public forest and park land, state trust land, Arizona is well known for its desert Basin and Range region in the states southern portions, which is rich in a landscape of xerophyte plants such as the cactus. This regions topography was shaped by volcanism, followed by the cooling-off. Its climate has hot summers and mild winters. The state is well known for its pine-covered north-central portion of the high country of the Colorado Plateau. Like other states of the Southwest United States, Arizona has an abundance of mountains, despite the states aridity, 27% of Arizona is forest, a percentage comparable to modern-day France or Germany. The worlds largest stand of pine trees is in Arizona

Mountain range
–
A mountain range is a geographic area containing numerous geologically related mountains. A mountain system or system of ranges, sometimes is used to combine several geological features that are geographically related. Mountain ranges are usually segmented by highlands or mountain passes and valleys, individual mountains within the same mountain range do not necessarily 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, most geologically young mountain ranges on the Earths land surface are associated with either the Pacific Ring of Fire or the Alpide Belt. The Andes is 7,000 kilometres long and is considered the worlds longest mountain system. The Alpide belt includes Indonesia and southeast Asia, through the Himalaya, the belt also includes other European and Asian mountain ranges. The Himalayas contain the highest mountains in the world, including Mount Everest, mountain ranges outside of these two systems include the Arctic Cordillera, the Urals, the Appalachians, the Scandinavian Mountains, the Altai Mountains and the Hijaz Mountains. If the definition of a range is stretched to include underwater mountains. The mountain systems of the earth are characterized by a tree structure, the sub-range relationship is often 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, and the White Mountains and the Blue Ridge Mountains are children of the Appalachians. The position of mountains influences climate, such as rain or snow, when air masses move up and over mountains, the air cools producing orographic precipitation. As the air descends on the side, it warms again and is drier. Often, a shadow will affect the leeward side of a range. Mountain ranges are constantly subjected to forces which work to tear them down. Erosion is at work while the mountains are being uplifted and long after until the mountains are reduced to low hills, rivers are traditionally believed to be the principle erosive factor on mountain ranges, with their ability of bedrock incision and sediment transport. The rugged topography of a range is the product of erosion. The basins adjacent to a mountain range are filled with sediments which are buried and turned into sedimentary rock. The early Cenozoic uplift of the Rocky Mountains of Colorado provides an example and this mass of rock was removed as the range was actively undergoing uplift

The Tucson Mountains are a minor mountain range west of Tucson, Arizona. The Tucson Mountains, including Wasson Peak, are one of four mountain ranges surrounding the Tucson Basin. The Santa Catalina Mountains lie to the northeast, the Rincon Mountains are to the east of Tucson, the Arizona-Sonora Desert Museum is located on the west flank of the Tucson Mountains. Much of the range is protected by Saguaro National Park and Tucson Mountain County Park, old Tucson Studios are located just west of the Tucson Mountains. Tucson Mountain Park was established April 1929, the Pima County Parks Commission, with C. B. Brown as its chairman, was established to oversee the park. At approximately 20,000 acres, the park is one of the largest natural resource areas owned and managed by a government in the U. S. The park has approximately 62 miles of non-motorized shared-use trails, the area is popular with hikers, mountain bikers, and equestrians. Saguaro National Park was created as a National Monument in 1933, the Tucson Mountain District of Saguaro National Park ranges from an elevation of 2,180 ft to 4,687 ft and contains 2 biotic communities, desert scrub, and desert grassland. Average annual precipitation is approximately 10.27 in, common wildlife include the coyote, Gambel’s quail, and desert tortoise. Kinney who worked with Brown in the creation of the park and McCain Loop was named for J. C. McCain, the first park ranger.

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

Santa Cruz River (Arizona)
–
The Santa Cruz River is a river in southern Arizona and northern Sonora, Mexico. It is approximately 184 miles long, between Nogales and Tucson the river valley is flanked by the San Cayetano and Santa Rita Mountains on the east and the Atascosa, Tumacacori, and Sierrita Mountains on the west. Most of the Santa Cruz River is usually a dry riverbed and this was not always the case, as it was a combination of human errors and natural catastrophes in the late nineteenth century that led to the decline of the Santa Cruz. The city of Nogales, Sonora, has been releasing treated sewage into the Santa Cruz River and this has resulted in the revival of several miles of riverbank within and north of the city of Nogales, Arizona. The Juan Bautista de Anza National Historic Trail parallels much of the Santa Cruz, in Marana, there are approximately ten paved miles of multi-use recreational path along the Santa Cruz, located on Tangerine Road and through the Gladden Farms community park

The University of Arizona is a public research university in Tucson, Arizona, United States. Founded in 1885, the UA was the first university in the Arizona Territory, the university operates two medical schools and is affiliated with the regions only academic medical centers. The university is home to the James E. Rogers College of Law and numerous other nationally ranked graduate. During the 2015-2016 academic year, there was an enrollment of 43,088 students. The University of Arizona is governed by the Arizona Board of Regents, the University of Arizona is one of the elected members of the Association of American Universities and is the only representative from the state of Arizona to this group. Known as the Arizona Wildcats, the teams are members of the Pac-12 Conference of the NCAA. UA athletes have won titles in several sports, most notably mens basketball, baseball. The official colors of the university and its teams are UA Red. After the passage of the Morrill Land-Grant Act of 1862, the push for a university in Arizona grew, the University of Arizona was approved by the Arizona Territorys Thieving Thirteenth Legislature in 1885, which also selected the city of Tucson to receive the appropriation to build the university. Tucson had hoped to receive the appropriation for the mental hospital. Tucson was largely disappointed with receiving what was viewed as an inferior prize. Construction of Old Main, the first building on campus, began on October 27,1887, and classes met for the first time in 1891 with 32 students in Old Main, which is still in use today. Because there were no schools in Arizona Territory, the university maintained separate preparatory classes for the first 23 years of operation. The University of Arizona offers 334 fields of study leading to bachelors, masters, doctoral, academic departments and programs are organized into colleges and schools. Currently, grades are given on a strict 4-point scale with A worth 4, B worth 3, C worth 2, D worth 1 and E worth zero points. In 2004, there were discussions with students and faculty that may lead the UA towards eventual usage of the grading system in future years. As of December 2015, the university uses the 4-points scale. The Center for World University Rankings in 2015 ranked Arizona 68th in the world, the 2015–16 Times Higher Education World University Rankings rated University of Arizona 163rd in the world and the 2016/17 QS World University Rankings ranked it 233rd

Basalt
–
Basalt is a common extrusive igneous rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of a planet or moon. Flood basalt describes the formation in a series of basalt flows. By definition, basalt is an igneous rock with generally 45-55% silica and less than 10% feldspathoid by volume. Basalt commonly features a very fine-grained or glassy matrix interspersed with visible mineral grains, the average density is 3.0 gm/cm3. Basalt is defined by its content and texture, and physical descriptions without mineralogical context may be unreliable in some circumstances. Basalt is usually grey to black in colour, but rapidly weathers to brown or rust-red due to oxidation of its mafic minerals into hematite, although usually characterized as dark, basaltic rocks exhibit a wide range of shading due to regional geochemical processes. Due to weathering or high concentrations of plagioclase, some basalts can be quite light-coloured and these phenocrysts usually are of olivine or a calcium-rich plagioclase, which have the highest melting temperatures of the typical minerals that can crystallize from the melt. Basalt with a texture is called vesicular basalt, when the bulk of the rock is mostly solid. Gabbro is often marketed commercially as black granite and these ultramafic volcanic rocks, with silica contents below 45% are usually classified as komatiites. Agricola applied basalt to the black rock of the Schloßberg at Stolpen. Tholeiitic basalt is relatively rich in silica and poor in sodium, included in this category are most basalts of the ocean floor, most large oceanic islands, and continental flood basalts such as the Columbia River Plateau. Basalt rocks are in some cases classified after their content in High-Ti and Low-Ti varieties. High-Ti and Low-Ti basalts have been distinguished in the Paraná and Etendeka traps and it has greater than 17% alumina and is intermediate in composition between tholeiite and alkali basalt, the relatively alumina-rich composition is based on rocks without phenocrysts of plagioclase. Alkali basalt is relatively poor in silica and rich in sodium and it is silica-undersaturated and may contain feldspathoids, alkali feldspar and phlogopite. Boninite is a form of basalt that is erupted generally in back-arc basins. Ocean island basalt Lunar basalt On Earth, most basalt magmas have formed by melting of the mantle. Basalt commonly erupts on Io, the third largest moon of Jupiter, and has formed on the Moon, Mars, Venus. The crustal portions of oceanic tectonic plates are composed predominantly of basalt, produced from upwelling mantle below, the mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene

Eusebio Kino
–
Eusebio Francisco Kino, was an Italian Jesuit, missionary, geographer, explorer, cartographer and astronomer. For the last 24 years of his life he worked in the then known as the Pimería Alta, modern-day Sonora in Mexico. He explored the region and worked with the indigenous Native American population, including primarily the Tohono OOdham, Sobaipuri and he proved that the Baja California Peninsula is not an island by leading an overland expedition there. By the time of his death he had established 24 missions, Kino was born Eusebius Chinus in the village of Segno, then in the sovereign Prince-bishopric of Trent, a part of the Holy Roman Empire. Other sources cite his name as Eusebio Francesco Chini and his parents were Franciscus Chinus and Margherita Luchi. The exact date of his birth is unknown but he was baptized on 10 August 1645 in the parish church, Kino was educated in Innsbruck, Austria, and after recuperating from a serious illness, he joined the Society of Jesus on 20 November 1665. From 1664-69, he received training as a member of the Society at Freiburg, Ingolstadt. After completing a stage of training in the Society, during which he taught mathematics in Ingolstadt. Although Kino wanted to go to the Orient, he was sent to New Spain, due to travel delays while crossing Europe, he missed the ship on which he was to travel and had to wait a year for another ship. While waiting in Cádiz, Spain, he wrote some observations, done during late 1680 and early 1681, about his study of a comet, which he published as the Exposición astronómica de el cometa. This publication was later the subject of a sonnet by the noted colonial nun and poet of New Spain, Sor Juana Inés de la Cruz, kinos first assignment was to lead the Atondo expedition to the Baja California peninsula of Las Californias Province of New Spain. He established the Misión San Bruno in 1683, after a prolonged drought there in 1685, Kino and the Jesuit missionaries were forced to abandon the mission and return to the viceregal capital of Mexico City. See also Spanish missions in the Sonoran Desert Father Kino began his career in the Pimería Alta on the morning of 14 March 1687,24 years and this was the morning he left Cucurpe, a town once considered the Rim of Christendom. Once Father Kino arrived in the Pimería Alta, at the request of the natives, subsequently Kino traveled across northern Mexico, and to present day California and Arizona. He followed ancient trading routes established millennia prior by the natives and these trails were later expanded into roads. His many expeditions on horseback covered over 50,000 square miles, Kino was important in the economic growth of the area, working with the already agricultural indigenous native peoples and introducing them to European seed, fruits, herbs and grains. He also taught them to raise cattle, sheep and goats, kinos initial mission herd of twenty cattle imported to Pimería Alta grew during his period to 70,000. Historian Herbert Bolton referred to Kino as Arizonas first rancher, in his travels in the Pimería Alta, Father Kino interacted with 16 different tribes
