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

John Wesley Powell
–
John Wesley Wes Powell was a U. S. soldier, geologist, explorer of the American West, professor at Illinois Wesleyan University, and director of major scientific and cultural institutions. He is famous for the 1869 Powell Geographic Expedition, a river trip down the Green and Colorado rivers. Powell served as director of the U. S. Geological Survey and proposed, for development of the arid West. Powell was born in Mount Morris, New York, in 1834 and his father, a poor itinerant preacher, had emigrated to the U. S. from Shrewsbury, England, in 1830. His family moved westward to Jackson, Ohio, then Walworth County, Wisconsin, before settling in rural Boone County, as a young man he undertook a series of adventures through the Mississippi River valley. In 1855, he spent four months walking across Wisconsin, during 1856, he rowed the Mississippi from St. Anthony, Minnesota, to the sea. In 1857, he rowed down the Ohio River from Pittsburgh to the Mississippi River, in 1858 he rowed down the Illinois River, then up the Mississippi and the Des Moines River to central Iowa. At age 25, he was elected in 1859 to the Illinois Natural History Society, Powell studied at Illinois College, Illinois Institute, and Oberlin College, over a period of seven years while teaching, but was unable to attain his degree. During his studies Powell acquired a knowledge of Ancient Greek and Latin, Powell had a restless nature and a deep interest in the natural sciences. This desire to learn natural sciences was against the wishes of his father. In 1860 when Powell was on a tour he decided that the Civil War was inevitable, he decided to study military science. Powells loyalties remained with the Union and the cause of abolishing slavery, on May 8,1861, he enlisted at Hennepin, Illinois, as a private in the 20th Illinois Infantry. He was described as age 27, height 5 6-1/2 tall, light complected, gray eyes, auburn hair and he was elected sergeant-major of the regiment, and when the 20th Illinois was mustered into the Federal service a month later, Powell was commissioned a second lieutenant. He enlisted in the Union Army as a cartographer, topographer, during the Civil War, he served first with the 20th Illinois Volunteers. While stationed at Cape Girardeau, Missouri, he recruited a company that became Battery F of the 2nd Illinois Light Artillery with Powell as captain. On November 28,1861, Powell took a leave to marry the former Emma Dean. At the Battle of Shiloh, he lost most of his arm when struck by a minie ball while in the process of giving the order to fire. The raw nerve endings in his arm would continue to cause him pain for the rest of his life

Newport, Rhode Island
–
Newport is a seaside city on Aquidneck Island in Newport County, Rhode Island, United States. The City of Newport is located approximately 37 miles southeast of Providence,21 miles south of Fall River and it is known as a New England summer resort and famous for its mansions. It was a major 18th-century port city and also contains a number of surviving buildings from the colonial era of the United States. The city is the county seat of Newport County and it was known for being the city of some of the Summer White Houses during the administrations of Presidents Dwight D. Eisenhower and John F. Kennedy. The population was 24,027 as of 2013 and its eight founders and first officers were Nicholas Easton, William Coddington, John Clarke, John Coggeshall, William Brenton, Jeremy Clark, Thomas Hazard, and Henry Bull. They left Portsmouth, Rhode Island after a fallout with Anne Hutchinson. As part of the agreement, Coddington and his followers took control of the side of the island. They were soon joined by Nicholas Easton, who had recently expelled from Massachusetts Bay Colony for holding heretical beliefs. The settlement grew to be the largest of the four settlements of Rhode Island. Many of the first colonists in Newport became Baptists, and the second Baptist congregation in Rhode Island was formed in 1640 under the leadership of John Clarke, peace did not last long in Newport, as many did not like Coddingtons autocratic style. As a result, a counter-faction was formed by 1650, led by Nicholas Easton, Newport became the most important port in colonial Rhode Island, and a public school was established in 1640. In 1658, a group of Jews were allowed to settle in Newport who were fleeing the Inquisition in Spain, the Newport congregation is now referred to as Congregation Jeshuat Israel and is the second-oldest Jewish congregation in the United States. It meets in Touro Synagogue, the oldest standing synagogue in the United States, in 1663, the colony of Rhode Island and Providence Plantations received its Royal Charter, and Benedict Arnold was elected its first Governor at Newport. The commercial activity which raised Newport to its fame as a port was begun by a second wave of Portuguese Jews who settled there about the middle of the 18th century. They brought with them experience and connections, capital. Most prominent among those were Jacob Rodrigues Rivera who arrived in 1745, Rivera introduced into America the manufacture of sperm oil, which became one of the leading industries and made Newport rich. Newports inhabitants who were engaged in whaling developed 17 manufactories of oil and candles, Aaron Lopez fled to Newport from Lisbon in 1752 and is credited with making Newport an important center of trade. To him in a degree than to any one else was due the rapid commercial development which made Newport for a quarter of a century afterward the most formidable rival of New York

Phoenix, Arizona
–
Phoenix is the capital and most populous city of the U. S. state of Arizona. Phoenix is the anchor of the Phoenix metropolitan area, also known as the Valley of the Sun, the metropolitan area is the 12th largest by population in the United States, with approximately 4.3 million people as of 2010. Settled in 1867 as a community near the confluence of the Salt and Gila Rivers. Located in the reaches of the Sonoran Desert, Phoenix has a subtropical desert climate. Despite this, its canal system led to a farming community, many of the original crops remaining important parts of the Phoenix economy for decades, such as alfalfa, cotton, citrus. The city averaged a four percent annual growth rate over a 40-year period from the mid-1960s to the mid-2000s. This growth rate slowed during the Great Recession of 2007–09, and has rebounded slowly, Phoenix is the cultural center of the Valley of the Sun, as well as the entire state. For more than 2,000 years, the Hohokam people occupied the land that would become Phoenix, the Hohokam created roughly 135 miles of irrigation canals, making the desert land arable. Paths of these canals would later used for the modern Arizona Canal, Central Arizona Project Canal. The Hohokam also carried out trade with the nearby Anasazi, Mogollon and Sinagua. It is believed that between 1300 and 1450, periods of drought and severe floods led to the Hohokam civilizations abandonment of the area. After the departure of the Hohokam, groups of Akimel Oodham, Tohono Oodham and Maricopa tribes began to use the area, as well as segments of the Yavapai and Apache. The Oodham were offshoots of the Sobaipuri tribe, who in turn were thought to be the descendants of the formerly urbanized Hohokam and their crops included corn, beans, and squash for food, while cotton and tobacco were also cultivated. Mostly a peaceful group, they did together with the Maricopa for their mutual protection against incursions by both the Yuma and Apache tribes. The Tohono Oodham lived in the region as well, but their concentration was to the south. Living in small settlements, the Oodham were seasonal farmers who took advantage of the rains and they also hunted local game such as deer, rabbit, and javalina for meat. When the Mexican–American War ended in 1848, Mexico ceded its northern zone to the United States, the Phoenix area became part of the New Mexico Territory. In 1863 the mining town of Wickenburg was the first to be established in what is now Maricopa County, at the time Maricopa County had not yet been incorporated, the land was within Yavapai County, which included the major town of Prescott to the north of Wickenburg

Yale University
–
Yale University is an American private Ivy League research university in New Haven, Connecticut. Founded in 1701 in Saybrook Colony to train Congregationalist ministers, it is the third-oldest institution of education in the United States. The Collegiate School moved to New Haven in 1716, and shortly after was renamed Yale College in recognition of a gift from British East India Company governor Elihu Yale. Originally restricted to theology and sacred languages, the curriculum began to incorporate humanities and sciences by the time of the American Revolution. In the 19th century the school introduced graduate and professional instruction, awarding the first Ph. D. in the United States in 1861 and organizing as a university in 1887. Yale is organized into fourteen constituent schools, the undergraduate college, the Yale Graduate School of Arts and Sciences. While the university is governed by the Yale Corporation, each schools faculty oversees its curriculum, the universitys assets include an endowment valued at $25.4 billion as of June 2016, the second largest of any U. S. educational institution. The Yale University Library, serving all constituent schools, holds more than 15 million volumes and is the third-largest academic library in the United States, Yale College undergraduates follow a liberal arts curriculum with departmental majors and are organized into a social system of residential colleges. Almost all faculty teach courses, more than 2,000 of which are offered annually. Students compete intercollegiately as the Yale Bulldogs in the NCAA Division I – Ivy League, Yale has graduated many notable alumni, including five U. S. Presidents,19 U. S. Supreme Court Justices,20 living billionaires, and many heads of state. In addition, Yale has graduated hundreds of members of Congress,57 Nobel laureates,5 Fields Medalists,247 Rhodes Scholars, and 119 Marshall Scholars have been affiliated with the University. Yale traces its beginnings to An Act for Liberty to Erect a Collegiate School, passed by the General Court of the Colony of Connecticut on October 9,1701, the Act was an effort to create an institution to train ministers and lay leadership for Connecticut. Soon thereafter, a group of ten Congregationalist ministers, Samuel Andrew, Thomas Buckingham, Israel Chauncy, Samuel Mather, the group, led by James Pierpont, is now known as The Founders. Originally known as the Collegiate School, the institution opened in the home of its first rector, Abraham Pierson, the school moved to Saybrook, and then Wethersfield. In 1716 the college moved to New Haven, Connecticut, the feud caused the Mathers to champion the success of the Collegiate School in the hope that it would maintain the Puritan religious orthodoxy in a way that Harvard had not. Cotton Mather suggested that the school change its name to Yale College, meanwhile, a Harvard graduate working in England convinced some 180 prominent intellectuals that they should donate books to Yale. The 1714 shipment of 500 books represented the best of modern English literature, science, philosophy and it had a profound effect on intellectuals at Yale. Undergraduate Jonathan Edwards discovered John Lockes works and developed his original theology known as the new divinity

Sierra Nevada (U.S.)
–
The Sierra Nevada is a mountain range in the Western United States, between the Central Valley of California and the Basin and Range Province. The vast majority of the lies in the state of California. The Sierra runs 400 miles north-to-south, and is approximately 70 miles across east-to-west, the Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite, Sequoia, and Kings Canyon National Parks, the character of the range is shaped by its geology and ecology. More than one hundred years ago during the Nevadan orogeny. The range started to uplift four M. A. ago, the uplift caused a wide range of elevations and climates in the Sierra Nevada, which are reflected by the presence of five life zones. Uplift continues due to faulting caused by forces, creating spectacular fault block escarpments along the eastern edge of the southern Sierra. The Sierra Nevada has a significant history, the California Gold Rush occurred in the western foothills from 1848 through 1855. Due to inaccessibility, the range was not fully explored until 1912, the Sierra Nevada lies in Central and Eastern California, with a very small but historically important spur extending into Nevada. West-to-east, the Sierra Nevadas elevation increases gradually from 1,000 feet in the Central Valley to an height of about 10,500 feet at its crest only 50–75 miles to the east. The east slope forms the steep Sierra Escarpment, unlike its surroundings, the range receives a substantial amount of snowfall and precipitation due to orographic lift. The Sierra Nevada stretches from the Susan River and Fredonyer Pass in the north to Tehachapi Pass in the south and it is bounded on the west by Californias Central Valley and on the east by the Basin and Range Province. The geographical boundary between the Sierra and the Cascades is virtually indistinguishable, with the Fredonyer Pass designation being traditional, physiographically, the Sierra is a section of the Cascade-Sierra Mountains province, which in turn is part of the larger Pacific Mountain System physiographic division. The range is drained on its western slope by the Central Valley watershed, the northern third of the western Sierra is part of the Sacramento River watershed, and the middle third is drained by the San Joaquin River. The eastern slope watershed of the Sierra is much narrower, its rivers flow out into the endorheic Great Basin of eastern California and western Nevada. Although none of the eastern rivers reach the sea, many of the streams from Mono Lake southwards are diverted into the Los Angeles Aqueduct which provides water to Southern California, the height of the mountains in the Sierra Nevada increases gradually from north to south. Between Fredonyer Pass and Lake Tahoe, the range from 5,000 feet to more than 9,000 feet. The crest near Lake Tahoe is roughly 9,000 feet high, farther south, the highest peak in Yosemite National Park is Mount Lyell

Geology
–
Geology is an earth science concerned with the solid Earth, the rocks of which it is composed, and the processes by which they change over time. Geology can also refer generally to the study of the features of any terrestrial planet. Geology gives insight into the history of the Earth by providing the evidence for plate tectonics, the evolutionary history of life. Geology also plays a role in engineering and is a major academic discipline. The majority of data comes from research on solid Earth materials. These typically fall into one of two categories, rock and unconsolidated material, the majority of research in geology is associated with the study of rock, as rock provides the primary record of the majority of the geologic history of the Earth. There are three types of rock, igneous, sedimentary, and metamorphic. The rock cycle is an important concept in geology which illustrates the relationships between three types of rock, and magma. When a rock crystallizes from melt, it is an igneous rock, the sedimentary rock can then be subsequently turned into a metamorphic rock due to heat and pressure and is then weathered, eroded, deposited, and lithified, ultimately becoming a sedimentary rock. Sedimentary rock may also be re-eroded and redeposited, and metamorphic rock may also undergo additional metamorphism, all three types of rocks may be re-melted, when this happens, a new magma is formed, from which an igneous rock may once again crystallize. Geologists also study unlithified material which typically comes from more recent deposits and these materials are superficial deposits which lie above the bedrock. Because of this, the study of material is often known as Quaternary geology. This includes the study of sediment and soils, including studies in geomorphology, sedimentology and this theory is supported by several types of observations, including seafloor spreading, and the global distribution of mountain terrain and seismicity. This coupling between rigid plates moving on the surface of the Earth and the mantle is called plate tectonics. The development of plate tectonics provided a basis for many observations of the solid Earth. Long linear regions of geologic features could be explained as plate boundaries, mid-ocean ridges, high regions on the seafloor where hydrothermal vents and volcanoes exist, were explained as divergent boundaries, where two plates move apart. Arcs of volcanoes and earthquakes were explained as convergent boundaries, where one plate subducts under another, transform boundaries, such as the San Andreas Fault system, resulted in widespread powerful earthquakes. Plate tectonics also provided a mechanism for Alfred Wegeners theory of continental drift and they also provided a driving force for crustal deformation, and a new setting for the observations of structural geology

Mountaineering
–
The term mountaineering describes the sport of mountain climbing, including ski mountaineering. Hiking in the mountains can also be a form of mountaineering when it involves scrambling, or short stretches of the more basic grades of rock climbing. All require experience, athletic ability, and technical knowledge to maintain safety, mountaineering is often called Alpinism, especially in European languages, which implies climbing with difficulty such high and often snow and ice-covered mountains as the Alps. A mountaineer with such great skill is called an Alpinist, historically, many cultures have harbored superstitions about mountains, which they often regarded as sacred due to their proximity with heaven, such as Mount Olympus for the Ancient Greeks. In 1492 Antoine de Ville, lord of Domjulien and Beaupré, was the first to ascend the Mont Aiguille, in France, with a team, using ladders. It appears to be the first recorded climb of any technical difficulty, in 1573 Francesco De Marchi and Francesco Di Domenico ascended Corno Grande, the highest peak in the Apennine Mountains. During the Enlightenment, as a product of the new spirit of curiosity for the natural world, in 1741 Richard Pococke and William Windham made a historic visit to Chamonix. By the early 19th century many of the peaks were reached, including the Grossglockner in 1800, the Ortler in 1804, the Jungfrau in 1811, the Finsteraarhorn in 1812. In 1808 Marie Paradis became the first female to climb Mont Blanc and this inaugurated what became known as the Golden age of alpinism, with the first mountaineering club - the Alpine Club - being founded in 1857. Well-known guides of the era include Christian Almer, Jakob Anderegg, Melchior Anderegg, J. J. Bennen, Michel Croz, in the early years of the golden age, scientific pursuits were intermixed with the sport, such as by the physicist John Tyndall. In the later years, it shifted to a more competitive orientation as pure sportsmen came to dominate the London-based Alpine Club and this ascent is generally regarded as marking the end of the mountaineering golden age. By this point the sport of mountaineering had largely reached its modern form, with a body of professional guides, equipment, mountaineering in the Americas became popular in the 1800s. In North America, Pikes Peak in the Colorado Rockies was first climbed by Edwin James, though lower than Pikes Peak, the heavily glaciated Fremont Peak in Wyoming was thought to be the tallest mountain in the Rockies when it was first climbed by John C. Frémont and two others in 1842, pico de Orizaba, the tallest peak in Mexico and third tallest in North America, was first climbed by U. S. military personnel which included William F. Raynolds and a half dozen other climbers in 1848. Heavily glaciated and more technical climbs in North American were not achieved until the late 19th, in 1897 Mount Saint Elias on the Alaska-Yukon border was summitted by the Duke of the Abruzzi and party. But it was not until 1913 that Mount Mckinley, the tallest peak in North America was successfully climbed by Hudson Stuck, Mount Logan, the tallest peak in Canada was first summitted by a half dozen climbers in 1925 in an expedition that took more than two months. In 1879-1880 the exploration of the highest Andes in South America began when English mountaineer Edward Whymper climbed Chimborazo, the summit of Aconcagua was finally reached on January 14,1897 by Swiss mountaineer Matthias Zurbriggen during an expedition led by Edward FitzGerald that began in December 1896. The Andes of Bolivia were first explored by Sir William Martin Conway in 1898 and it took until the late 19th century for European explorers to penetrate Africa

Sheffield Scientific School
–
Sheffield Scientific School was founded in 1847 as a school of Yale College in New Haven, Connecticut for instruction in science and engineering. Originally named the Yale Scientific School, it was renamed in 1861 in honor of Joseph E. Sheffield, the school was incorporated in 1871. The Sheffield Scientific School helped establish the model for the transition of U. S. higher education from a model to one which incorporated both the sciences and the liberal arts. Following World War I, however, its curriculum gradually became completely integrated with Yale College, the Sheff ceased to function as a separate entity in 1956. After technological developments in the nineteenth century such as the electric telegraph. Harvard established the Lawrence Scientific School in 1846 and Dartmouth began the Chandler Scientific School in 1852, the stage was set at Yale for the transition in education beginning in 1846, when professorships of agricultural chemistry and practical chemistry were established. In 1847, the School of Applied Chemistry became part of a newly created Department of Philosophy, classes and labs were hosted in the Second Presidents House on Yales Old Campus until funding and a suitable facility could be found. Norton died in 1852 and was replaced by John Addison Porter, Applied chemistry was followed in 1852 by a professorship of civil engineering establishing a school of engineering. These programs made up the Yale Scientific School, in 1853 and 1854, science and engineering courses were listed in the Yale College course catalog as offered by the Yale Scientific School. Porter elicited help from his father-in-law, Joseph Earl Sheffield, and in 1858, Sheffield donated funds, the old Yale Medical School building on the northeast corner of Grove and Prospect Streets was renovated and renamed Sheffield Hall. Sheffields building reinforced the division of Hillhouse Avenue into an upper, residential section, in 1861, the school became the Sheffield Scientific School in recognition of his generosity devoted to the promotion of the study of the natural, physical, and mathematical sciences. Sheffield was one of Yales greatest benefactors and continued to support the school throughout his life, Yale also received US$591,000 from his will as well as his house, the Sheffield mansion, designed and originally owned by Ithiel Town. The school also benefited from the Morrill Act starting in 1863, land grant status, however, was transferred to the Storrs Agricultural School in 1893 after arguments by the state grange that the school was not a proper farm school. A series of lectures, later known as the Sheffield Lectures was instituted by the school in 1866, professor Othniel Charles Marsh of the school led four Yale scientific expeditions in search of fossils in 1870-3. The Sheffield School innovated with a course offering science and mathematics as well as economics, English, geography, history, modern languages, philology. Unlike Yale College students at the time, Sheffield students had no dorms, no required chapel, no disciplinary marks, the Academical Department of Yale and Sheffield became rivals. The Ac students studied liberal arts and would look down on the practical Sheff students, the Yale Scientific Magazine was founded at Sheffield in 1894, the first student magazine devoted to the sciences. In 1872–73, Sheffield Scientific Schools first new building, North Sheffield Hall was built, designed by Josiah Cleaveland Cady and this was followed by Winchester Hall and Sheffield Chemical

Lake Champlain
–
Lake Champlain /ʃæmˈpleɪn/ is a natural freshwater lake in North America mainly within the borders of the United States but partially situated across the Canada–U. S. Border, in the Canadian province of Quebec, the New York portion of the Champlain Valley includes the eastern portions of Clinton County and Essex County. Most of this area is part of the Adirondack Park, there are recreational opportunities in the park and along the relatively undeveloped coastline of Lake Champlain. The cities of Plattsburgh, New York and Burlington, Vermont are on the western and eastern shores, respectively. The Quebec portion is in the county municipalities of Le Haut-Richelieu. There are a number of islands in the lake, the largest include Grand Isle, Isle La Motte, and North Hero, all part of Grand Isle County, Vermont. The Champlain Valley is the northernmost unit of a system known as the Great Appalachian Valley. The Champlain Valley is a section of the larger Saint Lawrence Valley. Lake Champlain is one of large lakes scattered in an arc through Labrador, in Canada, the northern United States. Although it is smaller than each of the Great Lakes, Lake Champlain is a body of fresh water. Approximately 1,269 km2 in area, the lake is roughly 201 km long and 23 km across at its widest point, the lake varies seasonally from about 95 to 100 ft above mean sea level. Lake Champlain drains nearly half of Vermont, and approximately 250,000 people get their water from the lake. The lake is fed in Vermont by the LaPlatte, Lamoille, Missisquoi, Poultney, and Winooski rivers, along with Lewis Creek, Little Otter Creek, and Otter Creek. In New York, it is fed by the Ausable, Boquet, Great Chazy, La Chute, Little Ausable, Little Chazy, Salmon, in Quebec, it is fed by the Pike River. It is connected to the Hudson River by the Champlain Canal, parts of the lake freeze each winter, and in some winters the entire lake surface freezes, referred to as closing. In July and August, the temperature reaches an average of 70 °F. The Chazy Reef is an extensive Ordovician carbonate rock formation extends from Tennessee to Quebec. It occurs in prominent outcropping at Goodsell Ridge, Isle La Motte, the oldest reefs are around The Head of the south end of the island, slightly younger reefs are found at the Fisk Quarry, and the youngest are in fields to the north

Mount Shasta
–
Mount Shasta is a potentially active volcano at the southern end of the Cascade Range in Siskiyou County, California. At an elevation of 14,179 feet, it is the second highest peak in the Cascades, Mount Shasta has an estimated volume of 85 cubic miles, which makes it the most voluminous stratovolcano in the Cascade Volcanic Arc. The mountain and its area are managed by the U. S. Forest Service as part of the Shasta–Trinity National Forest. Mount Shasta is connected to nearby Shastina, and they dominate the northern California landscape and it rises abruptly and stands nearly 10,000 ft above the surrounding terrain. On a clear day, snowy Mount Shasta can be seen from the floor of the Central Valley 140 miles to the south. The mountain has attracted the attention of poets, authors, if Shastina were a separate mountain, it would rank as the fourth-highest peak of the Cascade Range. Mount Shastas surface is free of deep glacial erosion except, paradoxically. This is the largest glacial valley on the volcano, although it not now have a glacier in it. There are seven named glaciers on Mount Shasta, with the four largest radiating down from high on the summit cone to below 10,000 ft primarily on the north. The Whitney Glacier is the longest, and the Hotlum is the most voluminous glacier in the state of California. Three of the smaller named glaciers occupy cirques near and above 11,000 ft on the south and southeast sides, including the Watkins, Konwakiton, and Mud Creek glaciers. The oldest known human habitation in the dates to about 7,000 years ago. The historic eruption of Mount Shasta in 1786 may have been observed by Lapérouse, although perhaps first seen by Spanish explorers, the first reliably reported land sighting of Mount Shasta by a European or American was by Peter Skene Ogden in 1826. In 1827, the name Sasty or Sastise was given to nearby Mount McLoughlin by Ogden, the name was transferred to present-day Mount Shasta in 1841, partly as a result of work by the United States Exploring Expedition. Beginning in the 1820s, Mount Shasta was a prominent landmark along what became known as the Siskiyou Trail, the Siskiyou Trail was on the track of an ancient trade and travel route of Native American footpaths between Californias Central Valley and the Pacific Northwest. The California Gold Rush brought the first Euro-American settlements into the area in the early 1850s, including at Yreka, California, the first recorded ascent of Mount Shasta occurred in 1854, after several earlier failed attempts. In 1856, the first women reached the summit, by the 1860s and 1870s, Mount Shasta was the subject of scientific and literary interest. A book by California pioneer and entrepreneur James Hutchings, titled Scenes of Wonder and Curiosity in California, the summit was achieved by John Muir, Josiah Whitney, Clarence King, and John Wesley Powell

Louis Agassiz
–
Agassiz grew up in Switzerland, and studied and received Doctor of Philosophy and medical degrees at Erlangen and Munich, respectively. After further studies with Cuvier and Humboldt in Paris, Agassiz proceeded with leading to his appointment as professor of natural history at University of Neuchâtel. He made vast institutional and scientific contributions to zoology, geology, nevertheless, his reputation has suffered somewhat in hindsight by the evidence of his resistance to Darwinian evolution, and his later writings on human polygenism. Louis Agassiz was born in Môtier in the canton of Fribourg, educated first at home, then spending four years of secondary school in Bienne, he completed his elementary studies in Lausanne. In 1829 he received the degree of doctor of philosophy at Erlangen, moving to Paris he came under the tutelage of Alexander von Humboldt Humboldt and Georges Cuvier launched him on his careers of geology and zoology respectively. Previously he had not paid attention to the study of ichthyology. Spix, who died in 1826, did not live enough to work out the history of these fish. He at once threw himself into the work with an enthusiasm which characterized him to the end of his busy life, the task of describing the Brazilian fish was completed and published in 1829. This was followed by research into the history of the found in Lake Neuchâtel. Enlarging his plans, in 1830 he issued a prospectus of a History of the Freshwater Fish of Central Europe and it was only in 1839, however, that the first part of this publication appeared, and it was completed in 1842. In 1832 he was appointed professor of history in the University of Neuchâtel. The fossil fish there soon attracted his attention, the fossil-rich stones furnished by the slates of Glarus and the limestones of Monte Bolca were known at the time, but very little had been accomplished in the way of scientific study of them. Agassiz, as early as 1829, planned the publication of the work which, more than any other, five volumes of his Recherches sur les poissons fossiles appeared at intervals from 1833 to 1843. They were magnificently illustrated, chiefly by Joseph Dinkel, in gathering materials for this work Agassiz visited the principal museums in Europe, and meeting Cuvier in Paris, he received much encouragement and assistance from him. They had known him for seven years at the time, Agassiz found that his palaeontological labors made necessary a new basis of ichthyological classification. The fossils rarely exhibited any traces of the tissues of fish. They consisted chiefly of the teeth, scales and fins, with the bones being perfectly preserved in comparatively few instances. He therefore adopted a classification which divided fish into four groups, Ganoids, Placoids, Cycloids and Ctenoids, based on the nature of the scales, while Agassiz did much to improve fish taxonomy, his classification has been superseded by later work
