Itasca State Park
–
Itasca State Park is a state park of Minnesota, United States, and contains the headwaters of the Mississippi River. The park spans 32,690 acres of northern Minnesota, and is located about 21 miles north of Park Rapids, Minnesota and 25 miles from Bagley, Minnesota. The park is part of Minnesotas Pine Moraines and Outwash Plains Ecological Subsection and is contained within Clearwater, Hubbard, Henry Schoolcraft determined Lake Itasca as the rivers source in 1832. It was named as a National Natural Landmark in 1965, and was added to the National Register of Historic Places in 1973, about 500,000 people visit Itasca State Park annually. Approximately 7–8,000 years ago, Native American hunters pursued wild animals for food in the Itasca State Park region and these early people ambushed bison, deer, and moose at watering sites and killed them with stone–tipped spears. The bison kill site along Wilderness Drive in the park gives visitors historical insight about this period, a few thousand years later, a group of people of the Woodland Period arrived at Lake Itasca. They lived in larger, more permanent settlements and made a variety of stone, wood, burial mounds from this era can be seen today at the Itasca Indian Cemetery. In 1832 Anishinaabe guide Ozawindib led explorer Henry Schoolcraft to the source of the Mississippi River at Lake Itasca and it was on this journey that Schoolcraft, with the help of an educated missionary companion, created the name Itasca from the Latin words for truth and head. In the late 19th century, Jacob V. Brower, historian, anthropologist and land surveyor, Brower saw this region being quickly transformed by logging, and was determined to protect some of the pine forests for future generations. Through his conservation work and the efforts of others throughout the decades. Established in 1909, Itasca Biological Station and Labs is one of the oldest and largest continuously-operated inland field training centers in the United States and this site serves as a research facility and a site for summer-session undergraduate field biology courses for the University of Minnesota College of Biological Sciences. Lake Itasca, the source of the Mississippi River and a scenic area of northern Minnesota, has remained relatively unchanged from its natural state. Most of the area has a growth of timber that includes virgin red pine. Some of the red pine in Itasca are over 200 years old, the Itasca terrain is sometimes referred to as knob and kettle. The knobs are mounds of debris deposited directly by the ice near the edge of glaciers or by streams flowing on or under the glaciers surface. The kettles are depressions, usually filled with water, formed by dormant ice masses buried or partially buried under glacial debris that later melted. The retreat of the ice around 10,000 years ago left behind 157 lakes of varying size that cover 3,000 acres of Itasca State Park. The glaciers deposited a moraine, a combination of silt, clay, sand, the park also integrates 27,500 acres of upland and 1,500 acres of swamp

Minnesota

Minnesota is a state in the midwestern and northern regions of the United States. Minnesota was admitted as the 32nd U. S. state on May 11,1858, the state has a large number of lakes, and is known by the slogan Land of 10,000 Lakes. Its official motto is LÉtoile du Nord, Minnesota is the 12th largest in area and the 21st most populous of the U. S. Minnesota is known for its progressive political orientation and its high rate of civic participation and voter turnout. Until European settlement, Minnesota was inhabited by the Dakota and Ojibwe/Anishinaabe, in recent decades, immigration from Asia, the Horn of Africa, and Latin America has broadened its historic demographic and cultural composition. Minnesotas standard of living index is among the highest in the United States, Native Americans demonstrated the name to early settlers by dropping milk into water and calling it mnisota. Many places in the state have similar names, such as Minnehaha Falls, Minneiska, Minneota, Minnetonka, Minnetrista, and Minneapolis, a combination of mni and polis, Minnesota is the second northernmost U. S. state. Its isolated Northwest Angle in Lake of the Woods county is the part of the 48 contiguous states lying north of the 49th parallel. The state is part of the U. S. region known as the Upper Midwest and it shares a Lake Superior water border with Michigan and a land and water border with Wisconsin to the east. Iowa is to the south, North Dakota and South Dakota are to the west, with 86,943 square miles, or approximately 2.25 percent of the United States, Minnesota is the 12th-largest state. Minnesota has some of the Earths oldest rocks, gneisses that are about 3.6 billion years old. About 2.7 billion years ago, basaltic lava poured out of cracks in the floor of the primordial ocean, the roots of these volcanic mountains and the action of Precambrian seas formed the Iron Range of northern Minnesota. Following a period of volcanism 1, in more recent times, massive ice sheets at least one kilometer thick ravaged the landscape of the state and sculpted its terrain. The Wisconsin glaciation left 12,000 years ago and these glaciers covered all of Minnesota except the far southeast, an area characterized by steep hills and streams that cut into the bedrock. This area is known as the Driftless Zone for its absence of glacial drift, much of the remainder of the state outside the northeast has 50 feet or more of glacial till left behind as the last glaciers retreated. Gigantic Lake Agassiz formed in the northwest 13,000 years ago and its bed created the fertile Red River valley, and its outflow, glacial River Warren, carved the valley of the Minnesota River and the Upper Mississippi downstream from Fort Snelling. Minnesota is geologically quiet today, it experiences earthquakes infrequently, the states high point is Eagle Mountain at 2,301 feet, which is only 13 miles away from the low of 601 feet at the shore of Lake Superior. Notwithstanding dramatic local differences in elevation, much of the state is a rolling peneplain. Two major drainage divides meet in Minnesotas northeast in rural Hibbing, forming a triple watershed, precipitation can follow the Mississippi River south to the Gulf of Mexico, the Saint Lawrence Seaway east to the Atlantic Ocean, or the Hudson Bay watershed to the Arctic Ocean

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Body of Water is a musical conceived by Tony Kienitz and Tanna Herr with music by Jim Walker. It entails the life of fourteen teens left behind in a war crisis. The show was the production of A Theatre Near U. The show was adapted from music written by Jim Walker, the music for the show was nominated for Best Original Music by the San Francisco Bay Area Critics Circle Excellence in Theatre Awards. The album is available on iTunes here, the overall reception of Body of Water was positive. He also praised the music by Jim Walker as wonderfully raw, cryptic, richard Conema of Talkin Broadway and member of the Bay Area Theatre Critics Circle agreed with Jarrett on the music and choreography. He also said that the actors of the show are the adult performers of the future. These young people are doing work and many aspire to be professional actors. He also commended producing theatre company A Theatre Near U, saying that A Theatre Near U may have just fired the first shot in a revolution to determine the future of Youth Theatre

Glacial Lake
–
A glacial lake is a lake with origins in a melted glacier. They are formed when a glacier erodes the land, and then melts, near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes and this is apparent in the Lake District in Northwestern England where post-glacial sediments are normally between 4 and 6 metres deep. These lakes are surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations. The scouring action of the glaciers pulverizes minerals in the rock over which the glacier passes and these pulverized minerals become sediment at the bottom of the lake, and some of the rock flour becomes suspended in the water column. These suspended minerals support a population of algae, making the water appear green. These lakes are visible in aerial photos of landforms in regions that were glaciated during the last ice age. The coastlines near these areas are very irregular, reflecting the same geological process. By contrast, other areas have fewer lakes that often appear attached to rivers and these areas were carved more by water erosion. As seen in the English Lake District, the layers of the sediments at the bottom of the lakes contain evidence of the rate of erosion. The elemental make up of the sediments are not associated with the lakes themselves, the distribution of these elements, within the lake bed, are attributed to the condition of the drainage basin and the chemical composition of the water. The amount halogens and boron found in the sediments accompanies a change in erosional activity, the rate of deposition reflects the amount of halogen and boron in the deposited sediments.

Inflow (hydrology)
–
In hydrology, the inflow of a body of water is the source of the water in the body of water. It can also refer to the volume of incoming water in unit time. All bodies of water have multiple inflows, but often, one inflow may predominate, however, in many cases, no single inflow will predominate and there will be multiple primary inflows. For a lake, the inflow may be a river or stream that flows into the lake. Inflow may also be, strictly speaking, not flows, but rather precipitation, inflow can also be used to refer to groundwater recharge. The dictionary definition of inflow at Wiktionary

Discharge (hydrology)
–
In hydrology, discharge is the volume rate of water flow that is transported through a given cross-sectional area. It includes any suspended solids, dissolved chemicals, or biologic material in addition to the water itself, GH Dury and MJ Bradshaw are two hydrologists who devised the models showing the relationship between discharge and other variables in a river. The units that are used to express discharge include m³/s, ft³/s and/or acre-feet per day. For example, the discharge of the Rhine river in Europe is 2,200 cubic metres per second or 190,000,000 cubic metres per day. A commonly applied methodology for measuring, and estimating, the discharge of a river is based on a form of the continuity equation. In storm hydrology, an important consideration is the streams discharge hydrograph, the stream rises to a peak flow after each precipitation event, then falls in a slow recession. Because the peak flow also corresponds to the water level reached during the event. The amount of precipitation correlates to the volume of water that flows out of the river. The relationship between the discharge in the stream at a given cross-section and the level of the stream is described by a rating curve, average velocities and the cross-sectional area of the stream are measured for a given stream level. The velocity and the give the discharge for that level. After measurements are made for different levels, a rating table or rating curve may be developed. Once rated, the discharge in the stream may be determined by measuring the level, if a continuous level-recording device is located at a rated cross-section, the streams discharge may be continuously determined. Larger flows can transport more sediment and larger particles downstream than smaller flows due to their greater force, larger flows can also erode stream banks and damage public infrastructure

Mississippi River
–
The Mississippi River is the chief river of the largest drainage system on the North American continent. Flowing entirely in the United States, it rises in northern Minnesota, with its many tributaries, the Mississippis watershed drains all or parts of 31 U. S. states and 2 Canadian provinces between the Rocky and Appalachian Mountains. The Mississippi ranks as the fourth longest and fifteenth largest river in the world by discharge, the river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Native Americans long lived along the Mississippi River and its tributaries, most were hunter-gatherers, but some, such as the Mound Builders, formed prolific agricultural societies. The arrival of Europeans in the 16th century changed the way of life as first explorers, then settlers. The river served first as a barrier, forming borders for New Spain, New France, and the early United States, and then as a vital transportation artery and communications link. Formed from thick layers of the silt deposits, the Mississippi embayment is one of the most fertile agricultural regions of the country. In recent years, the river has shown a shift towards the Atchafalaya River channel in the Delta. The word itself comes from Messipi, the French rendering of the Anishinaabe name for the river, see below in the History section for additional information. In addition to historical traditions shown by names, there are at least two measures of a rivers identity, one being the largest branch, and the other being the longest branch. Using the largest-branch criterion, the Ohio would be the branch of the Lower Mississippi. Using the longest-branch criterion, the Middle Mississippi-Missouri-Jefferson-Beaverhead-Red Rock-Hellroaring Creek River would be the main branch and its length of at least 3,745 mi is exceeded only by the Nile, the Amazon, and perhaps the Yangtze River among the longest rivers in the world. The source of this waterway is at Browers Spring,8,800 feet above sea level in southwestern Montana and this is exemplified by the Gateway Arch in St. Louis and the phrase Trans-Mississippi as used in the name of the Trans-Mississippi Exposition. It is common to qualify a regionally superlative landmark in relation to it, the New Madrid Seismic Zone along the river is also noteworthy. These various basic geographical aspects of the river in turn underlie its human history and present uses of the waterway, the Upper Mississippi runs from its headwaters to its confluence with the Missouri River at St. Louis, Missouri. The source of the Upper Mississippi branch is traditionally accepted as Lake Itasca,1,475 feet above sea level in Itasca State Park in Clearwater County, however, the lake is in turn fed by a number of smaller streams. From its origin at Lake Itasca to St. Louis, Missouri, fourteen of these dams are located above Minneapolis in the headwaters region and serve multiple purposes, including power generation and recreation. The remaining 29 dams, beginning in downtown Minneapolis, all locks and were constructed to improve commercial navigation of the upper river

Drainage basin
–
A drainage basin or catchment area is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water. Drainage basins connect into other drainage basins at elevations in a hierarchical pattern, with smaller sub-drainage basins. Other terms used to describe drainage basins are catchment, catchment basin, drainage area, river basin and water basin. In closed drainage basins the water converges to a point inside the basin, known as a sink, which may be a permanent lake. The drainage basin acts as a funnel by collecting all the water within the covered by the basin. Each drainage basin is separated topographically from adjacent basins by a perimeter, drainage basins are similar but not identical to hydrologic units, which are drainage areas delineated so as to nest into a multi-level hierarchical drainage system. Hydrologic units are defined to allow multiple inlets, outlets, or sinks, in a strict sense, all drainage basins are hydrologic units but not all hydrologic units are drainage basins. Drainage basins of the oceans and seas of the world. Grey areas are endorheic basins that do not drain to the oceans, the following is a list of the major ocean basins, About 48. 7% of the worlds land drains to the Atlantic Ocean. The two major mediterranean seas of the world also flow to the Atlantic, The Caribbean Sea and Gulf of Mexico basin includes most of the U. S. The Mediterranean Sea basin includes much of North Africa, east-central Africa, Southern, Central, and Eastern Europe, Turkey, and the areas of Israel, Lebanon. Just over 13% of the land in the world drains to the Pacific Ocean, the Indian Oceans drainage basin also comprises about 13% of Earths land. It drains the eastern coast of Africa, the coasts of the Red Sea and the Persian Gulf, the Indian subcontinent, Burma, antarctica comprises approximately eight percent of the Earths land. The five largest river basins, from largest to smallest, are the basins of the Amazon, the Río de la Plata, the Congo, the Nile, and the Mississippi. The three rivers that drain the most water, from most to least, are the Amazon, Ganga, endorheic drainage basins are inland basins that do not drain to an ocean. Around 18% of all land drains to endorheic lakes or seas or sinks, the largest of these consists of much of the interior of Asia, which drains into the Caspian Sea, the Aral Sea, and numerous smaller lakes. Some of these, such as the Great Basin, are not single drainage basins but collections of separate, in endorheic bodies of standing water where evaporation is the primary means of water loss, the water is typically more saline than the oceans. An extreme example of this is the Dead Sea, drainage basins have been historically important for determining territorial boundaries, particularly in regions where trade by water has been important

Headwaters
–
The source or headwaters of a river or stream is the furthest place in that river or stream from its estuary or confluence with another river, as measured along the course of the river. As an example of the definition above, the USGS at times considers the Missouri River as a tributary of the Mississippi River. But it also follows the first definition above in using the combined Missouri - lower Mississippi length figure in lists of lengths of rivers around the world. This definition, from geographer Andrew Johnston of the Smithsonian Institution, is used by the National Geographic Society when pinpointing the source of rivers such as the Amazon or Nile. A definition given by the state of Montana agrees, stating that a source is never a confluence but is in a location that is the farthest, along water miles. Under this definition neither a lake nor a confluence of tributaries can be a river source. Likewise, the source of the Amazon River has been determined this way, when not listing river lengths, however, alternative definitions may be used. In the case of the Missouri River, Lewis and Clark would have had to travel to the east. to reach the source. Sometimes the source of the most remote tributary may be in an area that is more marsh-like, for example, the source of the River Tees is marshland. The furthest stream is often called the headstream. Headwaters are often small streams with cool waters because of shade and they may also be glacial headwaters, waters formed by the melting of glacial ice. Headwater areas are the areas of a watershed, as opposed to the outflow or discharge of a watershed. The river source is often but not always on or quite near the edge of the watershed, for example, the source of the Colorado River is at the Continental Divide separating the Atlantic Ocean and Pacific Ocean watersheds of North America. A river is considered a geographic feature, with only one mouth. For an example, note how the Mississippi River and Missouri River sources are officially defined, U. S. Geological Survey Geographic Names Information System, Mississippi River, Length,2,340 miles, Source, 47°14′22″N 95°12′29″W U. S. For example, The River Thames rises in Gloucestershire, the White Nile rises in the Great Lakes region of central Africa. The word source, when applied to lakes rather than rivers or streams, refers to the lakes inflow

Anishinaabe language
–
Ojibwe /oʊˈdʒɪbweɪ/, also known as Chippewa or Otchipwe, is an Indigenous language of North America of the Algonquian language family. Ojibwe is characterized by a series of dialects that have local names, there is no single dialect that is considered the most prestigious or most prominent, and no standard writing system that covers all dialects. The relative autonomy of the dialects of Ojibwe is associated with an absence of linguistic or political unity among Ojibwe-speaking groups. The latter two cover approximately the territory as Central Ojibwa, which he does not recognize. Ojibwe is a relatively healthy indigenous language, the Waadookodaading Ojibwe Language Immersion School teaches all classes to children in Ojibwe only. The Algonquian language family of which Ojibwe is a member is itself a member of the Algic language family, other Algic languages being Wiyot, Ojibwe is sometimes described as a Central Algonquian language, along with Fox, Cree, Menominee, Miami-Illinois, Potawatomi, and Shawnee. The most general indigenous designation for the language is Anishinaabemowin speaking the language, with varying spellings. Some speakers use the term Ojibwemowin, the general term in Oji-Cree is Anihshininiimowin, although Anishinaabemowin is widely recognized by Severn speakers. Some speakers of Saulteaux Ojibwe refer to their language as Nakawemowin, the Ottawa dialect is sometimes referred to as Daawaamwin, although the general designation is Nishnaabemwin, with the latter term also applied to Jibwemwin or Eastern Ojibwe. Other local terms are listed in Ojibwe dialects, English terms include Ojibwe, with variants including Ojibwa and Ojibway. The related term Chippewa is more commonly employed in the United States, Ojibwe and Potawatomi are frequently viewed as being more closely related to each other than to other Algonquian languages. A discussion of Algonquian family subgroups indicates that Ojibwe–Potawatomi is another possibility that awaits investigation, in a proposed consensus classification of Algonquian languages, Goddard classifies Ojibwa and Potawatomi as Ojibwayan, although no supporting evidence is adduced. The Central languages share a significant number of common features, groups of speakers of the Ottawa dialect migrated to Kansas and Oklahoma during the historical period, with a small amount of linguistic documentation of the language in Oklahoma. The presence of Ojibwe in British Columbia has been noted, current census data indicate that all varieties of Ojibwe are spoken by approximately 56,531 people. This figure reflects census data from the 2000 United States census, the Red Lake, White Earth, and Leech Lake reservations are known for their tradition of singing hymns in the Ojibwe language. As of 2011, Ojibwe is the language of Red Lake. Because the dialects of Ojibwe are at least partly mutually intelligible, Ojibwe is usually considered to be a language with a number of dialects. Conventionally regarded as a language consisting of a continuum of dialectal varieties since

He is also noted for his major six-volume study of American Indians in the 1850s. She taught him the Ojibwe language and much about her maternal culture and they had several children, two of whom survived past childhood. She is now recognized as the first Native American literary writer in the United States, in 1846 the widower Schoolcraft was commissioned by Congress for a major study, known as Indian Tribes of the United States, which was published in six volumes from 1851 to 1857. He married again in 1847, to Mary Howard, from a family in South Carolina. In 1860 she published the bestselling The Black Gauntlet, an anti-Uncle Toms Cabin novel, Schoolcraft was born in 1793 in Guilderland, Albany County, New York, the son of Lawrence Schoolcraft and Anne Barbara Schoolcraft. He entered Union College at age 15 and later attended Middlebury College and he was especially interested in geology and mineralogy. His father was a glassmaker, and Henry initially studied and worked in the same industry, Schoolcraft wrote his first paper on the topic, Vitreology. After working in several works in New York, Vermont and New Hampshire. From November 18 to February 1819, Schoolcraft and his companion Levi Pettibone made an expedition from Potosi, Missouri and they traveled further down the White River into Arkansas, making a survey of the geography, geology, and mineralogy of the area. Schoolcraft published this study in A View of the Lead Mines of Missouri, in this book he correctly identified the potential for lead deposits in the region, Missouri eventually became the number one lead-producing state. He also published Journal of a Tour into the Interior of Missouri and Arkansaw and this expedition and his resulting publications brought Schoolcraft to the attention of the Secretary of War, John C. Calhoun, who saw him as a man of industry, ambition, beginning in the spring of 1820, Schoolcraft served as a geologist on the Lewis Cass expedition. The expedition was intended to establish the source of the Mississippi River, the expedition traveled as far upstream as Upper Red Cedar Lake in present-day Minnesota. Since low water precluded navigating farther upstream, the lake was designated the rivers headwaters, Schoolcrafts account of the expedition was published as A Narrative Journal of Travels Through the Northwestern Regions. to the Sources of the Mississippi River. In 1821 he was a member of another government expedition that traveled through Illinois, Indiana, in 1832, he led a second expedition to the headwaters of the Mississippi River. Arriving a month earlier than had the 1820 expedition, he was able to take advantage of water to navigate to Lake Itasca. Schoolcraft met his first wife soon after being assigned in 1822 to Sault Ste, marie, Michigan, as its first US Indian agent. Two years before, the government had built Fort Brady and wanted to establish a presence to forestall any renewed British threat following the War of 1812

Latin

Latin is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets, Latin was originally spoken in Latium, in the Italian Peninsula. Through the power of the Roman Republic, it became the dominant language, Vulgar Latin developed into the Romance languages, such as Italian, Portuguese, Spanish, French, and Romanian. Latin, Italian and French have contributed many words to the English language, Latin and Ancient Greek roots are used in theology, biology, and medicine. By the late Roman Republic, Old Latin had been standardised into Classical Latin, Vulgar Latin was the colloquial form spoken during the same time and attested in inscriptions and the works of comic playwrights like Plautus and Terence. Late Latin is the language from the 3rd century. Later, Early Modern Latin and Modern Latin evolved, Latin was used as the language of international communication, scholarship, and science until well into the 18th century, when it began to be supplanted by vernaculars. Ecclesiastical Latin remains the language of the Holy See and the Roman Rite of the Catholic Church. Today, many students, scholars and members of the Catholic clergy speak Latin fluently and it is taught in primary, secondary and postsecondary educational institutions around the world. The language has been passed down through various forms, some inscriptions have been published in an internationally agreed, monumental, multivolume series, the Corpus Inscriptionum Latinarum. Authors and publishers vary, but the format is about the same, volumes detailing inscriptions with a critical apparatus stating the provenance, the reading and interpretation of these inscriptions is the subject matter of the field of epigraphy. The works of several hundred ancient authors who wrote in Latin have survived in whole or in part and they are in part the subject matter of the field of classics. The Cat in the Hat, and a book of fairy tales, additional resources include phrasebooks and resources for rendering everyday phrases and concepts into Latin, such as Meissners Latin Phrasebook. The Latin influence in English has been significant at all stages of its insular development. From the 16th to the 18th centuries, English writers cobbled together huge numbers of new words from Latin and Greek words, dubbed inkhorn terms, as if they had spilled from a pot of ink. Many of these words were used once by the author and then forgotten, many of the most common polysyllabic English words are of Latin origin through the medium of Old French. Romance words make respectively 59%, 20% and 14% of English, German and those figures can rise dramatically when only non-compound and non-derived words are included. Accordingly, Romance words make roughly 35% of the vocabulary of Dutch, Roman engineering had the same effect on scientific terminology as a whole

River source
–
The source or headwaters of a river or stream is the furthest place in that river or stream from its estuary or confluence with another river, as measured along the course of the river. As an example of the definition above, the USGS at times considers the Missouri River as a tributary of the Mississippi River. But it also follows the first definition above in using the combined Missouri - lower Mississippi length figure in lists of lengths of rivers around the world. This definition, from geographer Andrew Johnston of the Smithsonian Institution, is used by the National Geographic Society when pinpointing the source of rivers such as the Amazon or Nile. A definition given by the state of Montana agrees, stating that a source is never a confluence but is in a location that is the farthest, along water miles. Under this definition neither a lake nor a confluence of tributaries can be a river source. Likewise, the source of the Amazon River has been determined this way, when not listing river lengths, however, alternative definitions may be used. In the case of the Missouri River, Lewis and Clark would have had to travel to the east. to reach the source. Sometimes the source of the most remote tributary may be in an area that is more marsh-like, for example, the source of the River Tees is marshland. The furthest stream is often called the headstream. Headwaters are often small streams with cool waters because of shade and they may also be glacial headwaters, waters formed by the melting of glacial ice. Headwater areas are the areas of a watershed, as opposed to the outflow or discharge of a watershed. The river source is often but not always on or quite near the edge of the watershed, for example, the source of the Colorado River is at the Continental Divide separating the Atlantic Ocean and Pacific Ocean watersheds of North America. A river is considered a geographic feature, with only one mouth. For an example, note how the Mississippi River and Missouri River sources are officially defined, U. S. Geological Survey Geographic Names Information System, Mississippi River, Length,2,340 miles, Source, 47°14′22″N 95°12′29″W U. S. For example, The River Thames rises in Gloucestershire, the White Nile rises in the Great Lakes region of central Africa. The word source, when applied to lakes rather than rivers or streams, refers to the lakes inflow

Gulf of Mexico
–
The Gulf of Mexico is an ocean basin largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U. S. states of Alabama, Florida, Louisiana, Mississippi and Texas border the Gulf on the north, Atlantic and Pacific coasts, or sometimes the south coast, in juxtaposition to the Great Lakes region being the north coast. One of the seven main areas is the Gulf of Mexico basin. The Gulf of Mexico formed approximately 300 million years ago as a result of plate tectonics, the Gulfs basin is roughly oval and is approximately 810 nautical miles wide and floored by sedimentary rocks and recent sediments. It is connected to part of the Atlantic Ocean through the Florida Straits between the U. S. and Cuba, and with the Caribbean Sea via the Yucatan Channel between Mexico and Cuba, with the narrow connection to the Atlantic, the Gulf experiences very small tidal ranges. The size of the Gulf basin is approximately 1.6 million km2, almost half of the basin is shallow continental shelf waters. The basin contains a volume of roughly 2,500 quadrillion liters, the consensus among geologists who have studied the geology of the Gulf of Mexico, is that prior to the Late Triassic, the Gulf of Mexico did not exist. It was created by the collision of plates that formed Pangea. As interpreted by Roy Van Arsdale and Randel T. Cox, geologists and other Earth scientists agree in general that the present Gulf of Mexico basin originated in Late Triassic time as the result of rifting within Pangea. The rifting was associated with zones of weakness within Pangea, including sutures where the Laurentia, South American, first, there was a Late Triassic-Early Jurassic phase of rifting during which rift valleys formed and filled with continental red beds. Second, as rifting progressed through Early and Middle Jurassic time and it was at this time that tectonics first created a connection to the Pacific Ocean across central Mexico and later eastward to the Atlantic Ocean. This flooded the basin created by rifting and crustal thinning to create the Gulf of Mexico. While the Gulf of Mexico was a basin, the subsiding transitional crust was blanketed by the widespread deposition of Louann Salt. Initially, during the Late Jurassic, continued rifting widened the Gulf of Mexico and progressed to the point that sea-floor spreading, at this point, sufficient circulation with the Atlantic Ocean was established that the deposition of Louann Salt ceased. During the Late Jurassic through Early Cretaceous, the occupied by the Gulf of Mexico experienced a period of cooling. The subsidence was the result of a combination of stretching, cooling. Initially, the combination of stretching and cooling caused about 5–7 km of tectonic subsidence of the central thin transitional

Nile River
–
The Nile is a major north-flowing river in northeastern Africa. It is generally regarded as the longest river in the world, in particular, the Nile is the primary water source of Egypt and Sudan. The Nile has two tributaries, the White Nile and Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself, the Blue Nile, however, is the source of most of the water and silt. The White Nile is longer and rises in the Great Lakes region of central Africa and it flows north through Tanzania, Lake Victoria, Uganda and South Sudan. The Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast, the two rivers meet just north of the Sudanese capital of Khartoum. The northern section of the river flows north almost entirely through the Sudanese desert to Egypt, then ends in a large delta, Egyptian civilization and Sudanese kingdoms have depended on the river since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of Aswan, in the ancient Egyptian language, the Nile is called Ḥpī or Iteru, meaning river. In Coptic, the words piaro or phiaro meaning the river come from the ancient name. The English name Nile and the Arabic names en-Nîl and an-Nîl both derive from the Latin Nilus and the Ancient Greek Νεῖλος, beyond that, however, the etymology is disputed. One possible etymology derives it from a Semitic Nahal, meaning river, the standard English names White Nile and Blue Nile, to refer to the rivers source, derive from Arabic names formerly applied only to the Sudanese stretches which meet at Khartoum. Above Khartoum, the Nile is also known as the White Nile, at Khartoum the river is joined by the Blue Nile. The White Nile starts in equatorial East Africa, and the Blue Nile begins in Ethiopia, both branches are on the western flanks of the East African Rift. The drainage basin of the Nile covers 3,254,555 square kilometers, the source of the Nile is sometimes considered to be Lake Victoria, but the lake has feeder rivers of considerable size. It is either the Ruvyironza, which emerges in Bururi Province, Burundi, or the Nyabarongo, the two feeder rivers meet near Rusumo Falls on the Rwanda-Tanzania border. Gish Abay is reportedly the place where the water of the first drops of the Blue Nile develop. The Nile leaves Lake Nyanza at Ripon Falls near Jinja, Uganda and it flows north for some 130 kilometers, to Lake Kyoga. For the remaining part it flows westerly through the Murchison Falls until it reaches the very northern shores of Lake Albert where it forms a significant river delta

Amazon River

The Amazon River, usually abbreviated to Amazon, in South America is the largest river by discharge of water in the world and, according to some authors, the longest in length. Brazilians call this section the Solimões River above its confluence with the Rio Negro to form what Brazilians call the Amazon at the Meeting of Waters at Manaus, the rivers largest city. The Amazon basin is the largest drainage basin in the world, the portion of the rivers drainage basin in Brazil alone is larger than any other rivers basin. The Amazon enters Brazil with only one-fifth of the flow it finally discharges into the Atlantic Ocean, during what many archaeologists call the formative stage, Amazonian societies were deeply involved in the emergence of South Americas highland agrarian systems. Early human settlements were based on low-lying hills or mounds. Shell mounds were the earliest evidences of inhabitation, they represent piles of refuse and are mainly dated between 7500 and 4000 years BP. They are associated with ceramic age cultures, no preceramic shell mounds have been documented so far by archaeologists, artificial earth platforms for entire villages are the second type of mounds. They are best represented by the Marajoara culture, figurative mounds are the most recent types of occupation. There is ample evidence that the surrounding the Amazon River were home to complex and large-scale indigenous societies, mainly chiefdoms who developed large towns. Archeologists estimate that by the time the Spanish conquistador De Orellana travelled across the Amazon in 1541 and these pre-Columbian settlements created highly developed civilizations. For instance, pre-Columbian indigenous people on the island of Marajó may have developed social stratification, in order to achieve this level of development, the indigenous inhabitants of the Amazon rainforest altered the forests ecology by selective cultivation and the use of fire. Scientists argue that by burning areas of the forest repetitiously, the people caused the soil to become richer in nutrients. This created dark soil areas known as terra preta de índio, further research has hypothesized that this practice began around 11,000 years ago. Some say that its effects on forest ecology and regional climate explain the otherwise inexplicable band of rainfall through the Amazon basin. Many indigenous tribes engaged in constant warfare, james Stuart Olson wrote, The Munduruku expansion dislocated and displaced the Kawahíb, breaking the tribe down into much smaller groups. First came to the attention of Europeans in 1770 when they began a series of attacks on Brazilian settlements along the Amazon River. In March 1500, Spanish conquistador Vicente Yáñez Pinzón was the first documented European to sail up the Amazon River. Pinzón called the stream Río Santa María del Mar Dulce, later shortened to Mar Dulce, literally, sweet sea, because of its fresh water pushing out into the ocean

Lewis Cass
–
During his long political career, Cass served as an American ambassador to France, and as a U. S. A Mason from his years as a man in Ohio, Cass was co-founder of the Grand Lodge of Michigan. Cass was nationally known in the antebellum period as a leading spokesman for the controversial Doctrine of Popular Sovereignty. It proposed allowing voters in the United States territories to determine whether to allow slavery in each jurisdiction rather than having Congress determine this, in 1848 Cass ran as a presidential candidate for the Democratic Party but lost to Zachary Taylor. Lewis Cass was born in 1782 in Exeter, New Hampshire and he attended the private Phillips Exeter Academy. His parents were Major Jonathan Cass, a Revolutionary War veteran, in 1800 the family moved to Marietta, Ohio, part of a wave of westward migration after the end of the war and defeat of Native Americans in the Northwest Indian War. Cass became an attorney, practicing in Zanesville, Ohio, on May 26,1806, Cass married Elizabeth Spencer. That same year, he was elected to the Ohio House of Representatives, the following year, President Thomas Jefferson appointed Cass as the U. S. He achieved his Fellowcraft degree on April 2,1804, on June 24,1805, he was admitted as Charter member of Lodge of Amity 105, Zanesville. He served as the first Worshipful Master of Lodge of Amity in 1806, Cass was one of the founders of the Grand Lodge of Ohio, representing Lodge of Amity at the first meeting on January 4,1808. He was elected Deputy Grand Master on January 5,1809, and Grand Master on January 3,1810, January 8,1811, when the War of 1812 began against Great Britain, he took command of the 3rd Ohio Volunteer Regiment. He became colonel of the 27th United States Infantry Regiment on February 20,1813, soon after, he was promoted to brigadier general in the Regular Army on March 12,1813. Cass took part in the Battle of the Thames, a defeat of British Canadian forces, Cass resigned from the Army on May 1,1814. Overall, the war closed in, essentially, a draw, as a reward for his military service, Cass was appointed Governor of the Michigan Territory by President James Madison on October 29,1813, serving until 1831. As he was traveling on business, several territorial secretaries often acted as governor in his place. During this period, he helped negotiate and implement treaties with Native American tribes in Michigan, some were given small reservations in the territory. This helped open up areas of Michigan to settlement by European Americans and that same year, Cass was named to serve as Secretary of War under President James Monroe, but he declined the honor. In 1820, Cass led an expedition to the part of the Michigan Territory

Cass Lake (Minnesota)
–
Cass Lake is a glacially-formed lake in north central Minnesota in the United States. In the Ojibwe language, it is called Gaa-miskwaawaakokaag, and was known to early explorers and traders in French as Lac du Cedre Rouge and it is the 11th largest lake in Minnesota, and the 8th largest lake lying entirely within the borders of the state. The lake contains five islands, including Star Island, Cedar Island, the Mississippi River flows through the lake from west to east. A second major stream, the Turtle River, enters the lake from the north, the lake has a large littoral area, particularly around Cedar Island. Star Island is notable in that it contains the 199 acres -sized Lake Windigo, in July 1820, an expedition led by General Lewis Cass visited the lake. In June 1832, Henry Schoolcraft, who had been a member of the 1820 expedition, designated the source of the river as being further upstream at Lake Itasca, the source of the perennial stream. Subsequent to the Cass Expedition of 1820, the lake was renamed Cass Lake in order to distinguish it from Red Cedar Lake in Aitkin County, the lake is popular destination for recreational fishing, boating, and swimming. The lake is known for its walleye, northern pike, muskellunge, there are numerous campgrounds and resorts located on its shores. The southern and eastern shores of the lake, as well as all the islands, are protected within the Ten Section Area of the Chippewa National Forest. Norway Beach recreation area is located at the southeast corner of the lake, and contains Norway Beach Lodge, the city of Cass Lake sits near the southwestern side of the lake. Formerly, the played a important role in the lumber industry. Log booms were towed across the lake by steamboat from surrounding lakes and streams to either be sawed into lumber at local mills, historically, Cass Lake was considered to be much larger. Pike Bay is a 4,760 acres lake lying to the south of Cass Lake, formerly, the two lakes were connected by a 0.6 mi wide shallow narrows. Beginning in 1898, construction of a railroad, and later highway and pipeline, across the narrows led to decreased currents through, the two bodies of water are now generally considered separate lakes, although Pike Bay retains its old name. The lake level is maintained and stabilized by Knutson Dam, built in 1924 to replace earlier brush, Knutson Dam is one of the few dams managed by the U. S. Forest Service. On the small isthmus between Cass Lake and neighboring Buck Lake lies Camp Chippewa, a camp founded in 1935. Another camp, UniStar, lies on a portion of Star Island, Schoolcraft River Lake Bemidji List of Minnesota lakes Camp Chippewa Camp UniStar

Channel (geography)
–
In physical geography, a channel is a type of landform consisting of the outline of a path of relatively shallow and narrow body of fluid, most commonly the confine of a river, river delta or strait. The word is cognate to canal, and sometimes shows in this form, most examples of this are fjords in the Pacific Northwest, a notable exception is the Casiquiare canal. All likely share borrowing from Spanish, Portuguese or French, channels can be either natural or human-made. A channel is typically outlined in terms of its bed and banks, Channel initiation refers to the site on a mountain slope where water begins to flow between identifiable banks. This site is referred to as the head and it marks an important boundary between hillslope processes and fluvial processes. The channel head is the most upslope part of a network and is defined by flowing water between defined identifiable banks. A channel head forms as overland flow and/or subsurface flow accumulate to a point where shear stress can overcome resistance of the ground surface. Channel heads are associated with colluvium, hollows and landslides. Overland flow is a factor in channel initiation where saturation overland flow deepens to increase shear stress. Overland flows converge in topographical depressions where channel initiation begins, soil composition, vegetation, precipitation, and topography dictate the amount and rate of overland flow. The composition of a soil determines how quickly saturation occurs and cohesive strength retards the entrainment of material from overland flows, vegetation slows infiltration rates during precipitation events and plant roots anchor soil on hillslopes. Subsurface flow destabilizes soil and resurfaces on hillslopes where channel heads are often formed and this often results in abrupt channel heads and landslides. Natural channels are formed by fluvial process and are found across the Earth and these are mostly formed by flowing water from the hydrological cycle, though can also be formed by other fluids such as flowing lava. Channels also describe the course through a reef, sand bar, bay. One example is the Columbia River, a located in the US states of Washington and Oregon. A stream channel is the confine of a stream consisting of a bed. Stream channels exist in a variety of geometries, Stream channel development is controlled by both water and sediment movement. There is a difference between low gradient streams and high gradient streams, a wide variety of stream channel types can be distinguished

Civilian Conservation Corps
–
The Civilian Conservation Corps was a public work relief program that operated from 1933 to 1942 in the United States for unemployed, unmarried men from relief families as part of the New Deal. Originally for young men ages 18–25, it was expanded to young men ages 17–28. Robert Fechner was the head of the agency, the CCC was designed to provide jobs for young men, and to relieve families who had difficulty finding jobs during the Great Depression in the United States. At the same time, it implemented a general natural resource conservation program in every state, maximum enrollment at any one time was 300,000. Over the course of its nine years in operation,3 million young men participated in the CCC, which provided them shelter, clothing. The American public made the CCC the most popular of all the New Deal programs, principal benefits of an individuals enrollment in the CCC included improved physical condition, heightened morale, and increased employability. The CCC operated separate programs for veterans and Native Americans, approximately 15,000 Native Americans participated in the program, helping them weather the Great Depression. Despite its popular support, the CCC was never a permanent agency and it depended on emergency and temporary Congressional legislation and funding to operate. By 1942, with World War II and the draft in operation, the need for work relief declined, as governor of New York, Roosevelt had run a similar program on a much smaller scale. He promised this law would provide 250,000 young men with meals, housing, uniforms, the Emergency Conservation Work Act was introduced to Congress the same day and enacted by voice vote on March 31. Roosevelt issued Executive Order 6101 on April 5,1933 which established the CCC organization and appointed a director, Robert Fechner, the organization and administration of the CCC was a new experiment in operations for a federal government agency. A CCC Advisory Council was composed of a representative each of the supervising departments. In addition, the Office of Education and Veterans Administration participated in the program, to end the opposition from labor unions Roosevelt chose Robert Fechner, vice president of the American Machinists Union, as director of the corps. William Green, head of the American Federation of Labor, was taken to the first camp to demonstrate that there would be no job training involved beyond simple manual labor. Reserve officers from the U. S. Army were in charge of the camps, General Douglas MacArthur was placed in charge of the program but said that the number of Army officers and soldiers assigned to the camps was affecting the readiness of the Regular Army. But the Army also found benefits in the program. When the draft began in 1940, the policy was to make CCC alumni corporals, CCC also provided command experience to Organized Reserve Corps officers. Through the CCC, the Regular Army could assess the performance of both Regular and Reserve Officers

The Real-Time Automated Personnel Identification System is a United States Department of Defense system used to issue the definitive credential within DoD. RAPIDS uses information stored in the DoD Defense Enrollment and Eligibility Reporting System when providing these credentials, used together, these two systems are commonly referred to as a DEERS/RAPIDS system or DEERS/RAPIDS infrastructure. These include, but are not limited to, Photographs Fingerprints The information is stored solely in the DEERS System, other redundant systems or repositories shall not be utilized without compelling justification for their need. RAPIDS provides distinct identification that is used as proof of identity and it may be used as a Geneva Convention Card in accordance with DoD Instruction 1000.13. It may also act as a card for Uniformed Services benefits. Ex, usage of the commissary on military installations or application for insurance discounts for veterans, DD FORM 1172-2, FEB2011, Application for Uniformed Services Identification Card/DEERS EnrollmentDoD Directive 1000.25 - DoD Personnel Identity Protection Program

Tourism is travel for pleasure or business, also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. Tourism may be international, or within the travellers country, Tourism can be domestic or international, and international tourism has both incoming and outgoing implications on a countrys balance of payments. Today, tourism is a source of income for many countries. International tourism receipts grew to US$1.03 trillion in 2011, the ITB Berlin is the worlds leading tourism trade fair. The word tourist was used by 1772 and tourism by 1811. It is formed from the tour, which is derived from Old English turian, from Old French torner, from Latin tornare, to turn on a lathe. Tourism is an important, even vital, source of income for many regions and it also creates opportunities for employment in the service sector of the economy associated with tourism. This is in addition to goods bought by tourists, including souvenirs, in 1936, the League of Nations defined a foreign tourist as someone traveling abroad for at least twenty-four hours. Its successor, the United Nations, amended this definition in 1945 and it includes movements for all purposes. In 1981, the International Association of Scientific Experts in Tourism defined tourism in terms of particular activities chosen and undertaken outside the home, in this context, travel has a similar definition to tourism, but implies a more purposeful journey. The terms tourism and tourist are sometimes used pejoratively, to imply a shallow interest in the cultures or locations visited, by contrast, traveler is often used as a sign of distinction. The sociology of tourism has studied the values underpinning these distinctions. International tourist arrivals reached 1.035 billion in 2012, up from over 996 million in 2011, the World Tourism Organization reports the following ten destinations as the most visited in terms of the number of international travellers in 2016. International tourism receipts grew to US$1.2 trillion in 2014, based upon air traffic, the MasterCard Global Destination Cities Index reports the following cities as the top ten most popular destinations of international tourism worldwide. MasterCard reports the following cities as the top ten biggest earners on international tourism worldwide in 2015, as early as Shulgi, however, kings praised themselves for protecting roads and building waystations for travelers. During the Roman Republic, spas and coastal resorts such as Baiae were popular among the rich, pausanias wrote his Description of Greece in the 2nd century AD. In ancient China, nobles sometimes made a point of visiting Mount Tai and, on occasion, the Islamic hajj is still central to its faith and Chaucers Canterbury Tales and Wu Chengens Journey to the West remain classics of English and Chinese literature. The 10th- to 13th-century Song dynasty also saw secular travel writers such as Su Shi, under the Ming, Xu Xiake continued the practice

Indigenous peoples of the Americas
–
The indigenous peoples of the Americas are the pre-Columbian peoples of the Americas and their descendants. The term Amerindian is used in Quebec, the Guianas, Indigenous peoples of the United States are commonly known as Native Americans or American Indians, and Alaska Natives. Application of the term Indian originated with Christopher Columbus, who, in his search for Asia, eventually, the Americas came to be known as the West Indies, a name still used to refer to the islands of the Caribbean Sea. This led to the blanket term Indies and Indians for the indigenous inhabitants, although some indigenous peoples of the Americas were traditionally hunter-gatherers—and many, especially in the Amazon basin, still are—many groups practiced aquaculture and agriculture. The impact of their agricultural endowment to the world is a testament to their time, although some societies depended heavily on agriculture, others practiced a mix of farming, hunting, and gathering. In some regions the indigenous peoples created monumental architecture, large-scale organized cities, chiefdoms, states, and empires. Many parts of the Americas are still populated by peoples, some countries have sizable populations, especially Belize, Bolivia, Chile, Ecuador, Greenland, Guatemala, Mexico. At least a different indigenous languages are spoken in the Americas. Some, such as the Quechuan languages, Aymara, Guaraní, Mayan languages, many also maintain aspects of indigenous cultural practices to varying degrees, including religion, social organization, and subsistence practices. Like most cultures, over time, cultures specific to many indigenous peoples have evolved to incorporate traditional aspects, some indigenous peoples still live in relative isolation from Western culture and a few are still counted as uncontacted peoples. The specifics of Paleo-Indian migration to and throughout the Americas, including the dates and routes traveled, are the subject of ongoing research. According to archaeological and genetic evidence, North and South America were the last continents in the world with human habitation. During the Wisconsin glaciation, 50–17,000 years ago, falling sea levels allowed people to move across the bridge of Beringia that joined Siberia to northwest North America. Alaska was a glacial refugium because it had low snowfall, allowing a small population to exist, the Laurentide Ice Sheet covered most of North America, blocking nomadic inhabitants and confining them to Alaska for thousands of years. Indigenous genetic studies suggest that the first inhabitants of the Americas share a single population, one that developed in isolation. The isolation of these peoples in Beringia might have lasted 10–20,000 years, around 16,500 years ago, the glaciers began melting, allowing people to move south and east into Canada and beyond. These people are believed to have followed herds of now-extinct Pleistocene megafauna along ice-free corridors that stretched between the Laurentide and Cordilleran Ice Sheets. Another route proposed involves migration - either on foot or using primitive boats - along the Pacific Northwest coast to the south, archeological evidence of the latter would have been covered by the sea level rise of more than 120 meters since the last ice age

USS Bancroft (1892)
–
USS Bancroft was a United States Navy steel gunboat, was laid down in 1891 at Elizabethport, New Jersey by Samuel L. Moore & Sons Shipyard and launched on 30 April 1892. She was commissioned on 3 March 1893 at the New York Navy Yard with Miss Mary Frances Moore as sponsor, Bancroft was designated as a training ship for the United States Naval Academy midshipmen and stationed at Annapolis, Maryland. Between 1893 and 1896, she cruised along the east coast visiting various shipyards with groups of midshipmen embarked, Naval expansion brought a corresponding increase on the Naval Academys enrollment, and the Bancroft quickly proved to be too small. After the practice cruise of 1896 it was converted to a gunboat with a reduced armament. On 15 September 1896, she sailed to join the European Squadron, called home when Congress declared war upon Spain, Bancroft reached Boston, Massachusetts, on 4 April 1898 and served with the North Atlantic Squadron from 9 May–9 August. She convoyed troop transports to Cuba and was on duty at Havana. On 28 July, Bancroft seized the small schooner Ensenada de Cortez, Bancroft returned to Boston on 2 September and was placed out of commission on 30 September 1898. During 1904 she returned to duties in the West Indies. On 29 January 1905 Bancroft departed San Juan, Puerto Rico, on 24 February she arrived at Norfolk, Virginia where she subsequently was placed out of commission on 2 March. Bancroft was transferred to the Revenue Cutter Service on 30 June 1906, initially homeported at Curtis Bay, Maryland, she made her first summer training cruise to Europe and the Mediterranean in 1907, also visiting Puerto Rico and the Virgin Islands. In 1909 the summer cruise included ports-of-call in Spain and Italy, when she was not being used as a training ship, Itasca was assigned relief duties for other Atlantic Coast cutters requiring yard availability for repairs. On 6 April 1917, the day Congress declared war on Germany, Itasca was in the harbor at San Juan, Puerto Rico and prevented the interned German ship KD-III from being scuttled by her crew. Heroic efforts by the division of Itasca managed to block the sabotaged sea valves in the engine room of KD-III even though the valves were under several feet of seawater. With the flooding finally under control, there was 14 ft of water in the hold and 18 ft in the forward hold. Secretary of the Navy Josephus Daniels commended the Itasca salvage team and gave the leader of the team and she was assigned patrol duties from the southern New Jersey coast to the entrance of Delaware Bay based out of Cold Spring, New Jersey. After the armistice, Itasca returned to the academy as a training vessel and her last training cruise was completed during the summer of 1920 arriving in New London on 3 October. A replacement training vessel, the former barkentine-rigged gunboat USS Vicksburg was acquired from the Navy on 1 July 1921, Itasca was decommissioned and sold in Baltimore, Maryland for $8250.00 on 11 May 1922 to Mr. Charles A. Jarding. Footnotes Citations References cited When was the Coast Guard established, canney, Donald L. U. S. Coast Guard and Revenue Cutters, 1790–1935

USCGC Itasca (1929)
–
The USCGC Itasca was a Lake-class cutter of the United States Coast Guard launched on 16 November 1929 and commissioned 12 July 1930. It acted as picket ship supporting Amelia Earharts 1937 world flight attempt, Itasca, stationed at Howland Island, tried to keep in radio contact with her. However, due to a series of misunderstandings or mishaps, two-way radio contact was never established, Itasca was decommissioned on lend lease to the United Kingdom where she received a name change, becoming HMS Gorleston after the East Anglian port of Gorleston on 30 May 1941. Gorlestone then resumed escorting eastern Atlantic and Mediterranean convoys until refit in Wales in December 1943, after refit, Gorleston escorted eastern Mediterranean convoys from March 1944 until assigned to the Kilindini Escort Force in August 1944. Gorleston escorted Arabian Sea convoys until transferred to Colombo in June 1945, Gorleston spent the remainder of the war escorting Bay of Bengal convoys in support of Operation Zipper.

Julius Chambers, F. R. G. S. was an American author, editor, journalist, travel writer, and activist against psychiatric abuse. Julius Chambers was born in Bellefontaine, Ohio in 1850, the son of Joseph, when he was only eleven years old, he began working as a printers devil in his uncles newspaper office. He first attended Ohio Wesleyan University, and later, Cornell University, at Cornell, he was a member of the Irving Literary Society. Around 1880, while working as a journalist he spent some time reading law with Attorney General Brewster in Philadelphia, after leaving Cornell, he became a reporter on the New York Tribune. While on sick leave on June 4,1872, he discovered Elk Lake, adjoining Lake Itasca, in the Lake District of Northwestern Minnesota, for this he was made a Fellow of the Royal Geographical Society. This led to a series of articles and the book The Mississippi River. Later in 1872, he returned to work and undertook an investigation of Bloomingdale Asylum, having himself committed with the help of some of his friends. His intent was to obtain information about alleged abuse of inmates, after ten days, his collaborators on the project had him released. This later led to the publication of the book A Mad World, from this time onward, Chambers was frequently invited to speak on the rights of the mentally ill and the need for proper facilities for their accommodation, care and treatment. In 1873, he joined the staff of the New York Herald, in 1887, his editor-in-chief sent him to Paris to launch the Paris Herald. In 1889, Chambers became the editor of the New York World on the invitation of Joseph Pulitzer. The charges were dismissed by the court and this sort of criminal action was common at the time and both Pulitzer and Chambers were indicted in a number of cases, in some of which they were acquitted, in others convicted. Chambers also wrote a column for the Brooklyn Daily Eagle, from 1904 onwards, called Walks and Talks and he continued his travel writing and lectured in journalism at Cornell University from 1903 to 1904, and at New York University in 1910. In addition to his works of fiction, he published over a short stories and had two plays produced in New York, both comedies. For years he was a member of the Lotos Club, New York, a Mad World and Its People a. k. a.

Minnesota Historical Society
–
The Minnesota Historical Society is a nonprofit educational and cultural institution dedicated to preserving the history of the U. S. state of Minnesota. It was founded by the legislature in 1849, almost a decade before statehood. The Society is named in the Minnesota Constitution and it is headquartered in the Minnesota History Center in downtown St. Paul. Although its focus is on Minnesota history it is not constrained by it and its work on the North American fur trade has been recognized in Canada as well. The Minnesota Historical Society operates 31 historic sites and museums,26 of which are open to the public, MNHS manages 14 sites directly and 10 in partnerships where the society maintains the resources and provides funding. Five sites are being held for preservation but are closed to public access, seven of the sites are National Historic Landmarks and 16 others are on the National Register of Historic Places. Seven sites lie within Minnesota state parks, and three are elements of the Mississippi National River and Recreation Area, journals and other documents of the Minnesota Historical Society.

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

Source (river or stream)
–
The source or headwaters of a river or stream is the furthest place in that river or stream from its estuary or confluence with another river, as measured along the course of the river. As an example of the definition above, the USGS at times considers the Missouri River as a tributary of the Mississippi River. But it also follows the first definition above in using the combined Missouri - lower Mississippi length figure in lists of lengths of rivers around the world. This definition, from geographer Andrew Johnston of the Smithsonian Institution, is used by the National Geographic Society when pinpointing the source of rivers such as the Amazon or Nile. A definition given by the state of Montana agrees, stating that a source is never a confluence but is in a location that is the farthest, along water miles. Under this definition neither a lake nor a confluence of tributaries can be a river source. Likewise, the source of the Amazon River has been determined this way, when not listing river lengths, however, alternative definitions may be used. In the case of the Missouri River, Lewis and Clark would have had to travel to the east. to reach the source. Sometimes the source of the most remote tributary may be in an area that is more marsh-like, for example, the source of the River Tees is marshland. The furthest stream is often called the headstream. Headwaters are often small streams with cool waters because of shade and they may also be glacial headwaters, waters formed by the melting of glacial ice. Headwater areas are the areas of a watershed, as opposed to the outflow or discharge of a watershed. The river source is often but not always on or quite near the edge of the watershed, for example, the source of the Colorado River is at the Continental Divide separating the Atlantic Ocean and Pacific Ocean watersheds of North America. A river is considered a geographic feature, with only one mouth. For an example, note how the Mississippi River and Missouri River sources are officially defined, U. S. Geological Survey Geographic Names Information System, Mississippi River, Length,2,340 miles, Source, 47°14′22″N 95°12′29″W U. S. For example, The River Thames rises in Gloucestershire, the White Nile rises in the Great Lakes region of central Africa. The word source, when applied to lakes rather than rivers or streams, refers to the lakes inflow

Missouri River

The Missouri River is the longest river in North America. Rising in the Rocky Mountains of western Montana, the Missouri flows east and south for 2,341 miles before entering the Mississippi River north of St. Louis, Missouri. The river takes drainage from a populated, semi-arid watershed of more than half a million square miles. When combined with the lower Mississippi River, it forms the fourth longest river system. For over 12,000 years, people have depended on the Missouri River and its tributaries as a source of sustenance and transportation. More than ten major groups of Native Americans populated the watershed, most leading a nomadic lifestyle, the Missouri River was one of the main routes for the westward expansion of the United States during the 19th century. The growth of the fur trade in the early 1800s laid much of the groundwork as trappers explored the region, pioneers headed west en masse beginning in the 1830s, first by covered wagon, then by the growing numbers of steamboats entering service on the river. Former Native American lands in the watershed were taken over by settlers, leading to some of the most longstanding, during the 20th century, the Missouri River basin was extensively developed for irrigation, flood control and the generation of hydroelectric power. Fifteen dams impound the main stem of the river, with more on tributaries. Meanders have been cut and the river channelized to improve navigation, from the Rocky Mountains of Montana and Wyoming, three streams rise to form the headwaters of the Missouri River. The longest begins near Browers Spring,9,100 feet above sea level, on the southeastern slopes of Mount Jefferson in the Centennial Mountains. Flowing west then north, it runs first in Hell Roaring Creek, then west into the Red Rock, swings northeast to become the Beaverhead and these two streams then flow north and northwest into Montana. The Missouri River officially starts at the confluence of the Jefferson and Madison in Missouri Headwaters State Park near Three Forks, Montana, the Missouri then passes through Canyon Ferry Lake, a reservoir west of the Big Belt Mountains. Issuing from the mountains near Cascade, the flows northeast to the city of Great Falls, where it drops over the Great Falls of the Missouri. Farther on, the passes through the Fort Peck Dam, and immediately downstream. At the confluence, the Yellowstone is actually the larger river, the Missouri then meanders east past Williston and into Lake Sakakawea, the reservoir formed by Garrison Dam. Below the dam the Missouri receives the Knife River from the west and flows south to Bismarck, the capital of North Dakota and it slows into the Lake Oahe reservoir just before the Cannonball River confluence. While it continues south, eventually reaching Oahe Dam in South Dakota, the Missouri makes a bend to the southeast as it winds through the Great Plains, receiving the Niobrara River and many smaller tributaries from the southwest

Montana

Montana /mɒnˈtænə/ is a state in the Western region of the United States. The states name is derived from the Spanish word montaña, Montana has several nicknames, although none official, including Big Sky Country and The Treasure State, and slogans that include Land of the Shining Mountains and more recently The Last Best Place. Montana has a 545-mile border with three Canadian provinces, British Columbia, Alberta, and Saskatchewan, the state to do so. It also borders North Dakota and South Dakota to the east, Wyoming to the south, Montana is ranked 4th in size, but 44th in population and 48th in population density of the 50 United States. The western third of Montana contains numerous mountain ranges, smaller island ranges are found throughout the state. In total,77 named ranges are part of the Rocky Mountains, the eastern half of Montana is characterized by western prairie terrain and badlands. The economy is based on agriculture, including ranching and cereal grain farming. Other significant economic activities include oil, gas, coal and hard rock mining, lumber, the health care, service, and government sectors also are significant to the states economy. Millions of tourists annually visit Glacier National Park, the Little Bighorn Battlefield National Monument, the name Montana comes from the Spanish word Montaña and the Latin word Montana, meaning mountain, or more broadly, mountainous country. Montaña del Norte was the name given by early Spanish explorers to the mountainous region of the west. The name was changed by Representatives Henry Wilson and Benjamin F. Harding, when Ashley presented a bill to establish a temporary government in 1864 for a new territory to be carved out of Idaho, he again chose Montana Territory. This time Rep. Samuel Cox, also of Ohio, objected to the name, Cox complained that the name was a misnomer given most of the territory was not mountainous and that a Native American name would be more appropriate than a Spanish one. Other names such as Shoshone were suggested, but it was decided that the Committee on Territories could name it whatever they wanted, with an area of 147,040 square miles, Montana is slightly larger than Japan. It is the fourth largest state in the United States after Alaska, Texas, and California, the largest landlocked U. S. state, and the worlds 56th largest national state/province subdivision. To the north, Montana shares a 545-mile border with three Canadian provinces, British Columbia, Alberta, and Saskatchewan, the state to do so. It borders North Dakota and South Dakota to the east, Wyoming to the south, the states topography is roughly defined by the Continental Divide, which splits much of the state into distinct eastern and western regions. Most of Montanas 100 or more named mountain ranges are in the western half. The Absaroka and Beartooth ranges in the states south-central part are part of the Central Rocky Mountains
