Horn Island (Mississippi)
Horn Island is a long, thin barrier island off the Gulf Coast of Mississippi, south of Ocean Springs. It is part of the Gulf Islands National Seashore. Horn Island is less than a mile wide at its widest point, it occupies about 11 square kilometers. The island, in part and bounds the Mississippi Sound to its north, has a long beach on the Gulf of Mexico on its south side; the island is undeveloped, except for a small ranger station mid-island. Part of the Gulf Islands National Seashore, it is a favorite boating destination for those living on the Mississippi Gulf Coast. Horn Island has long stretches of sugar-white sand, dunes punctuated with sea oats, tall pines on small groves, saw palmettos on small groves, a few inland lagoons, it is home to varied wildlife including alligators, pelicans, ibises, ducks, raccoons, tern and other migratory birds. The Sound and the Gulf host innumerable species of sea life. From 1943 to 1945, Horn Island was closed to all public access and activity for use as a biological weapons testing site by the U.
S. Army. From 1946-1965, Walter Inglis Anderson, an artist from Ocean Springs, Mississippi visited the island to draw and paint the landscapes and life on the island. Many of his works are on display at the Walter Anderson Museum in Ocean Springs. Horn is not alone in its small island group. Similar nearby islands include Petit Bois Island to the east, Ship Island and Cat Island to the west. Of the group, Horn Island is the largest. Gruinard Island Horn Island Testing Station Plum Island
Sterilization refers to any process that eliminates, kills, or deactivates all forms of life and other biological agents present in a specified region, such as a surface, a volume of fluid, medication, or in a compound such as biological culture media. Sterilization can be achieved through various means, including: heat, irradiation, high pressure, filtration. Sterilization is distinct from disinfection and pasteurization, in that sterilization kills, deactivates, or eliminates all forms of life and other biological agents which are present. One of the first steps toward sterilization was made by Nicolas Appert who discovered that thorough application of heat over a suitable period slowed the decay of foods and various liquids, preserving them for safe consumption for a longer time than was typical. Canning of foods has helped to reduce food borne illness. Other methods of sterilizing foods include high pressure. In general, surgical instruments and medications that enter an aseptic part of the body must be sterile.
Examples of such instruments include scalpels, hypodermic needles, artificial pacemakers. This is essential in the manufacture of parenteral pharmaceuticals. Preparation of injectable medications and intravenous solutions for fluid replacement therapy requires not only sterility but well-designed containers to prevent entry of adventitious agents after initial product sterilization. Most medical and surgical devices used in healthcare facilities are made of materials that are able to go under steam sterilization. However, since 1950, there has been an increase in medical devices and instruments made of materials that require low-temperature sterilization. Ethylene oxide gas has been used since the 1950s for heat- and moisture-sensitive medical devices. Within the past 15 years, a number of new, low-temperature sterilization systems have been developed and are being used to sterilize medical devices. Steam sterilization is the most used and the most dependable. Steam sterilization is nontoxic, inexpensive microbicidal and heats and penetrates fabrics.
There are strict international rules to protect the contamination of Solar System bodies from biological material from Earth. Standards vary depending on both the type of its destination. Many components of instruments used on spacecraft cannot withstand high temperatures, so techniques not requiring excessive temperatures are used as tolerated, including heating to at least 120 °C, chemical sterilization, oxidization and irradiation; the aim of sterilization is the reduction of present microorganisms or other potential pathogens. The degree of sterilization is expressed by multiples of the decimal reduction time, or D-value, denoting the time needed to reduce the initial number N 0 to one tenth of its original value; the number of microorganisms N after sterilization time t is given by: N N 0 = 10. The D-value is a function of sterilization conditions and varies with the type of microorganism, water activity, pH etc.. For steam sterilization the temperature, in degrees Celsius, is given as an index.
Theoretically, the likelihood of the survival of an individual microorganism is never zero. To compensate for this, the overkill method is used. Using the overkill method, sterilization is performed by sterilizing for longer than is required to kill the bioburden present on or in the item being sterilized; this provides a sterility assurance level equal to the probability of a non-sterile unit. For high-risk applications, such as medical devices and injections, a sterility assurance level of at least 10−6 is required by the United States Food and Drug Administration. A used method for heat sterilization is the autoclave, sometimes called a converter or steam sterilizer. Autoclaves use steam heated to 121–134 °C under pressure. To achieve sterility, the article is placed in a chamber and heated by injected steam until the article reaches a temperature and time setpoint. All the air is removed from the chamber, because air is undesired in the moist heat sterilization process; the article is held at the temperature setpoint for a period of time which varies depending on what bioburden is present on the article being sterilized and its resistance to steam sterilization.
A general cycle would be anywhere between 3 and 15 minutes, at 121 °C at 100 kPa, sufficient to provide a sterility assurance level of 10−4 for a product with a bioburden of 106 and a D-value of 2.0 minutes. Following sterilization, liquids in a pressurized autoclave must be cooled to avoid boiling over when the pressure is released; this may be achieved by depressurizing the sterilization chamber and allowing liqui
Washington, D. C. formally the District of Columbia and referred to as Washington or D. C. is the capital of the United States. Founded after the American Revolution as the seat of government of the newly independent country, Washington was named after George Washington, first President of the United States and Founding Father; as the seat of the United States federal government and several international organizations, Washington is an important world political capital. The city is one of the most visited cities in the world, with more than 20 million tourists annually; the signing of the Residence Act on July 16, 1790, approved the creation of a capital district located along the Potomac River on the country's East Coast. The U. S. Constitution provided for a federal district under the exclusive jurisdiction of the U. S. Congress, the District is therefore not a part of any state; the states of Maryland and Virginia each donated land to form the federal district, which included the pre-existing settlements of Georgetown and Alexandria.
The City of Washington was founded in 1791 to serve as the new national capital. In 1846, Congress returned the land ceded by Virginia. Washington had an estimated population of 702,455 as of July 2018, making it the 20th most populous city in the United States. Commuters from the surrounding Maryland and Virginia suburbs raise the city's daytime population to more than one million during the workweek. Washington's metropolitan area, the country's sixth largest, had a 2017 estimated population of 6.2 million residents. All three branches of the U. S. federal government are centered in the District: Congress and the U. S. Supreme Court. Washington is home to many national monuments, museums situated on or around the National Mall; the city hosts 177 foreign embassies as well as the headquarters of many international organizations, trade unions, non-profit, lobbying groups, professional associations, including the World Bank Group, the International Monetary Fund, the Organization of American States, AARP, the National Geographic Society, the Human Rights Campaign, the International Finance Corporation, the American Red Cross.
A locally elected mayor and a 13‑member council have governed the District since 1973. However, Congress may overturn local laws. D. C. residents elect a non-voting, at-large congressional delegate to the House of Representatives, but the District has no representation in the Senate. The District receives three electoral votes in presidential elections as permitted by the Twenty-third Amendment to the United States Constitution, ratified in 1961. Various tribes of the Algonquian-speaking Piscataway people inhabited the lands around the Potomac River when Europeans first visited the area in the early 17th century. One group known as the Nacotchtank maintained settlements around the Anacostia River within the present-day District of Columbia. Conflicts with European colonists and neighboring tribes forced the relocation of the Piscataway people, some of whom established a new settlement in 1699 near Point of Rocks, Maryland. In his Federalist No. 43, published January 23, 1788, James Madison argued that the new federal government would need authority over a national capital to provide for its own maintenance and safety.
Five years earlier, a band of unpaid soldiers besieged Congress while its members were meeting in Philadelphia. Known as the Pennsylvania Mutiny of 1783, the event emphasized the need for the national government not to rely on any state for its own security. Article One, Section Eight, of the Constitution permits the establishment of a "District as may, by cession of particular states, the acceptance of Congress, become the seat of the government of the United States". However, the Constitution does not specify a location for the capital. In what is now known as the Compromise of 1790, Alexander Hamilton, Thomas Jefferson came to an agreement that the federal government would pay each state's remaining Revolutionary War debts in exchange for establishing the new national capital in the southern United States. On July 9, 1790, Congress passed the Residence Act, which approved the creation of a national capital on the Potomac River; the exact location was to be selected by President George Washington, who signed the bill into law on July 16.
Formed from land donated by the states of Maryland and Virginia, the initial shape of the federal district was a square measuring 10 miles on each side, totaling 100 square miles. Two pre-existing settlements were included in the territory: the port of Georgetown, founded in 1751, the city of Alexandria, founded in 1749. During 1791–92, Andrew Ellicott and several assistants, including a free African American astronomer named Benjamin Banneker, surveyed the borders of the federal district and placed boundary stones at every mile point. Many of the stones are still standing. A new federal city was constructed on the north bank of the Potomac, to the east of Georgetown. On September 9, 1791, the three commissioners overseeing the capital's construction named the city in honor of President Washington; the federal district was named Columbia, a poetic name for the United States in use at that time. Congress held its first session in Washington on November 17, 1800. Congress passed the District of Columbia Organic Act of 1801 that organized the District and placed the entire territory under the exclusive control of the federal
Mississippi is a state located in the southeastern region of the United States. Mississippi is the 32nd most 34th most populous of the 50 United States, it is bordered by Tennessee to the north, Alabama to the east, the Gulf of Mexico and Louisiana to the south, Arkansas and Louisiana to the west. The state's western boundary is defined by the Mississippi River. Jackson, with a population of 167,000 people, is both the state's capital and largest city; the state is forested outside the Mississippi Delta area, the area between the Mississippi and Yazoo rivers. Before the American Civil War, most development in the state was along riverfronts, as the waterways were critical for transportation. Large gangs of slaves were used to work on cotton plantations. After the war, freedmen began to clear the bottomlands to the interior, in the process selling off timber and buying property. By the end of the 19th century, African Americans made up two-thirds of the Delta's property owners, but timber and railroad companies acquired much of the land after the financial crisis, which occurred when blacks were facing increasing racial discrimination and disfranchisement in the state.
Clearing of the land for plantations altered the Delta's ecology, increasing the severity of flooding along the Mississippi by taking out trees and bushes that had absorbed excess waters. Much land is now held by agribusinesses. A rural state with agricultural areas dominated by industrial farms, Mississippi is ranked low or last among the states in such measures as health, educational attainment, median household income; the state's catfish aquaculture farms produce the majority of farm-raised catfish consumed in the United States. Since the 1930s and the Great Migration of African Americans to the North and West, the majority of Mississippi's population has been white, although the state still has the highest percentage of black residents of any U. S. state. From the early 19th century to the 1930s, its residents were majority black, before the American Civil War that population was composed of African-American slaves. Democratic Party whites retained political power through disfranchisement and Jim Crow laws.
In the first half of the 20th century, nearly 400,000 rural blacks left the state for work and opportunities in northern and midwestern cities, with another wave of migration around World War II to West Coast cities. In the early 1960s, Mississippi was the poorest state in the nation, with 86% of its non-whites living below the poverty level. In 2010, 37% of Mississippians were African Americans, the highest percentage of African Americans in any U. S. state. Since regaining enforcement of their voting rights in the late 1960s, most African Americans have supported Democratic candidates in local and national elections. Conservative whites have shifted to the Republican Party. African Americans are a majority in many counties of the Mississippi-Yazoo Delta, an area of historic slave settlement during the plantation era; the state's name is derived from the Mississippi River. Settlers named it after the Ojibwe word misi-ziibi. Mississippi is bordered to the north by Tennessee, to the east by Alabama, to the south by Louisiana and a narrow coast on the Gulf of Mexico.
In addition to its namesake, major rivers in Mississippi include the Big Black River, the Pearl River, the Yazoo River, the Pascagoula River, the Tombigbee River. Major lakes include Ross Barnett Reservoir, Arkabutla Lake, Sardis Lake, Grenada Lake with the largest lake being Sardis Lake. Mississippi is composed of lowlands, the highest point being Woodall Mountain, in the foothills of the Cumberland Mountains, 807 feet above sea level; the lowest point is sea level at the Gulf Coast. The state's mean elevation is 300 feet above sea level. Most of Mississippi is part of the East Gulf Coastal Plain; the coastal plain is composed of low hills, such as the Pine Hills in the south and the North Central Hills. The Pontotoc Ridge and the Fall Line Hills in the northeast have somewhat higher elevations. Yellow-brown loess soil is found in the western parts of the state; the northeast is a region of fertile black earth. The coastline includes large bays at Bay St. Louis and Pascagoula, it is separated from the Gulf of Mexico proper by the shallow Mississippi Sound, sheltered by Petit Bois Island, Horn Island and West Ship Islands, Deer Island, Round Island, Cat Island.
The northwest remainder of the state consists of the Mississippi Delta, a section of the Mississippi Alluvial Plain. The plain widens north of Vicksburg; the region has rich soil made up of silt, deposited by the flood waters of the Mississippi River. Areas under the management of the National Park Service include: Brices Cross Roads National Battlefield Site near Baldwyn Gulf Islands National Seashore Natchez National Historical Park in Natchez Natchez Trace National Scenic Trail in Tupelo Natchez Trace Parkway Tupelo National Battlefield in Tupelo Vicksburg National Military Park and Cemetery in Vicksburg Mississippi City Population Rankings of at least 50,000: Mississippi City Population Rankings of at least 20,000 but fewer than 50,000: Mississippi City Population Rankings of at least 10,000 but fewer than 20,000: Mississippi has a humid
Maryland is a state in the Mid-Atlantic region of the United States, bordering Virginia, West Virginia, the District of Columbia to its south and west. The state's largest city is Baltimore, its capital is Annapolis. Among its occasional nicknames are Old Line State, the Free State, the Chesapeake Bay State, it is named after the English queen Henrietta Maria, known in England as Queen Mary. Sixteen of Maryland's twenty-three counties border the tidal waters of the Chesapeake Bay estuary and its many tributaries, which combined total more than 4,000 miles of shoreline. Although one of the smallest states in the U. S. it features a variety of climates and topographical features that have earned it the moniker of America in Miniature. In a similar vein, Maryland's geography and history combines elements of the Mid-Atlantic and South Atlantic regions of the country. One of the original Thirteen Colonies of Great Britain, Maryland was founded by George Calvert, a Catholic convert who sought to provide a religious haven for Catholics persecuted in England.
In 1632, Charles I of England granted Calvert a colonial charter, naming the colony after his wife, Queen Mary. Unlike the Pilgrims and Puritans, who enforced religious conformity in their settlements, Calvert envisioned a colony where people of different religious sects would coexist under the principle of toleration. Accordingly, in 1649 the Maryland General Assembly passed an Act Concerning Religion, which enshrined this principle by penalizing anyone who "reproached" a fellow Marylander based on religious affiliation. Religious strife was common in the early years, Catholics remained a minority, albeit in greater numbers than in any other English colony. Maryland's early settlements and population centers clustered around rivers and other waterways that empty into the Chesapeake Bay, its economy was plantation-based, centered on the cultivation of tobacco. The need for cheap labor led to a rapid expansion of indentured servants, penal labor, African slaves. In 1760, Maryland's current boundaries took form following the settlement of a long-running border dispute with Pennsylvania.
Maryland was an active participant in the events leading up to the American Revolution, by 1776 its delegates signed the Declaration of Independence. Many of its citizens subsequently played key military roles in the war. In 1790, the state ceded land for the establishment of the U. S. capital of Washington, D. C. Although a slave state, Maryland remained in the Union during the U. S. Civil War, its strategic location giving it a significant role in the conflict. After the war, Maryland took part in the Industrial Revolution, driven by its seaports, railroad networks, mass immigration from Europe. Since the Second World War, the state's population has grown to six million residents, it is among the most densely populated states in the nation; as of 2015, Maryland had the highest median household income of any state, owing in large part to its close proximity to Washington, D. C. and a diversified economy spanning manufacturing, higher education, biotechnology. Maryland has been ranked as one of the best governed states in the country.
The state's central role in American history is reflected by its hosting of some of the highest numbers of historic landmarks per capita. Maryland is comparable in overall area with Belgium, it is the 42nd largest and 9th smallest state and is closest in size to the state of Hawaii, the next smaller state. The next larger state, its neighbor West Virginia, is twice the size of Maryland. Maryland possesses a variety of topography within its borders, contributing to its nickname America in Miniature, it ranges from sandy dunes dotted with seagrass in the east, to low marshlands teeming with wildlife and large bald cypress near the Chesapeake Bay, to rolling hills of oak forests in the Piedmont Region, pine groves in the Maryland mountains to the west. Maryland is bounded on its north by Pennsylvania, on its west by West Virginia, on its east by Delaware and the Atlantic Ocean, on its south, across the Potomac River, by West Virginia and Virginia; the mid-portion of this border is interrupted by District of Columbia, which sits on land, part of Montgomery and Prince George's counties and including the town of Georgetown, Maryland.
This land was ceded to the United States Federal Government in 1790 to form the District of Columbia.. The Chesapeake Bay nearly bisects the state and the counties east of the bay are known collectively as the Eastern Shore. Most of the state's waterways are part of the Chesapeake Bay watershed, with the exceptions of a tiny portion of extreme western Garrett County, the eastern half of Worcester County, a small portion of the state's northeast corner. So prominent is the Chesapeake in Maryland's geography and economic life that there has been periodic agitation to change the state's official nickname to the "Bay State", a nickname, used by Massachusetts for decades; the highest point in Maryland, with an elevation of 3,360 feet, is Hoye Crest on Backbone Mountain, in the southwest corner of Garrett County, near the bo
Richard Milhous Nixon was an American politician who served as the 37th president of the United States from 1969 to 1974. He had served as the 36th vice president of the United States from 1953 to 1961, prior to that as both a U. S. representative and senator from California. Nixon was born in California. After completing his undergraduate studies at Whittier College, he graduated from Duke University School of Law in 1937 and returned to California to practice law, he and his wife Pat moved to Washington in 1942 to work for the federal government. He subsequently served on active duty in the U. S. Navy Reserve during World War II. Nixon was elected to the House of Representatives in 1946 and to the Senate in 1950, his pursuit of the Hiss Case established his reputation as a leading anti-communist and elevated him to national prominence. He was the running mate of Dwight D. Eisenhower, the Republican Party presidential nominee in the 1952 election. Nixon served for eight years as Vice President, becoming the second-youngest vice president in history at age 40.
He waged an unsuccessful presidential campaign in 1960, narrowly losing to John F. Kennedy, lost a race for governor of California to Pat Brown in 1962. In 1968, he ran for the presidency again and was elected, defeating incumbent Vice President Hubert Humphrey. Nixon ended American involvement in the war in Vietnam in 1973 and brought the American POWs home, ended the military draft. Nixon's visit to China in 1972 led to diplomatic relations between the two nations and he initiated détente and the Anti-Ballistic Missile Treaty with the Soviet Union the same year, his administration transferred power from Washington D. C. to the states. He imposed wage and price controls for ninety days, enforced desegregation of Southern schools, established the Environmental Protection Agency and began the War on Cancer. Nixon presided over the Apollo 11 moon landing, which signaled the end of the moon race, he was reelected in one of the largest electoral landslides in U. S. history in 1972 when he defeated George McGovern.
In his second term, Nixon ordered an airlift to resupply Israeli losses in the Yom Kippur War, resulting in the restart of the Middle East peace process and an oil crisis at home. The Nixon administration supported a coup in Chile that ousted the government of Salvador Allende and propelled Augusto Pinochet to power. By late 1973, the Watergate scandal escalated. On August 9, 1974, he resigned in the face of certain impeachment and removal from office—the only time a U. S. president has done so. After his resignation, he was issued a controversial pardon by Gerald Ford. In 20 years of retirement, Nixon wrote nine books and undertook many foreign trips, helping to rehabilitate his image into that of an elder statesman, he suffered a debilitating stroke on April 18, 1994 and died four days at the age of 81. Richard Milhous Nixon was born on January 9, 1913 in Yorba Linda, California, in a house, built by his father, his parents were Francis A. Nixon, his mother was a Quaker, his father converted from Methodism to the Quaker faith.
Nixon was a descendant of the early American settler, Thomas Cornell, an ancestor of Ezra Cornell, the founder of Cornell University, as well as of Jimmy Carter and Bill Gates. Nixon's upbringing was marked by evangelical Quaker observances of the time, such as refraining from alcohol and swearing. Nixon had four brothers: Harold, Donald and Edward. Four of the five Nixon boys were named after kings who had ruled in legendary Britain. Nixon's early life was marked by hardship, he quoted a saying of Eisenhower to describe his boyhood: "We were poor, but the glory of it was we didn't know it"; the Nixon family ranch failed in 1922, the family moved to Whittier, California. In an area with many Quakers, Frank Nixon opened a grocery gas station. Richard's younger brother. At the age of twelve, a spot was found on Richard's lung, with a family history of tuberculosis, he was forbidden to play sports; the spot was found to be scar tissue from an early bout of pneumonia. Young Richard attended East Whittier Elementary School, where he was president of his eighth-grade class.
His parents believed that attending Whittier High School had caused Richard's older brother Harold to live a dissolute lifestyle before he fell ill of tuberculosis, so they sent Richard to the larger Fullerton Union High School. He had to ride a school bus for an hour each way during his freshman year, he received excellent grades, he lived with an aunt in Fullerton during the week. He played junior varsity football, missed a practice though he was used in games, he had greater success as a debater, winning a number of championships and taking his only formal tutelage in public speaking from Fullerton's Head of English, H. Lynn Sheller. Nixon remembered Sheller's words, "Remember, speaking is conversation... don't shout at people. Talk to them. Converse with them." Nixon stated. At the start of his junior year beginning in September 1928, Richard's parents permitted him to transfer to Whittier High School. At Whittier High, Nixon suffered his first electoral defeat, for student body president, he rose at 4 a.m. to drive the family truck into Los Angeles and purchase vegetables at the market.
He drove to the store to wash and display them, befo
Utah is a state in the western United States. It became the 45th state admitted to the U. S. on January 4, 1896. Utah is the 13th-largest by area, 31st-most-populous, 10th-least-densely populated of the 50 United States. Utah has a population of more than 3 million according to the Census estimate for July 1, 2016. Urban development is concentrated in two areas: the Wasatch Front in the north-central part of the state, which contains 2.5 million people. Utah is bordered by Colorado to the east, Wyoming to the northeast, Idaho to the north, Arizona to the south, Nevada to the west, it touches a corner of New Mexico in the southeast. 62% of Utahns are reported to be members of The Church of Jesus Christ of Latter-day Saints, making Utah the only state with a majority population belonging to a single church. This influences Utahn culture and daily life; the LDS Church's world headquarters is located in Salt Lake City. The state is a center of transportation, information technology and research, government services, a major tourist destination for outdoor recreation.
In 2013, the U. S. Census Bureau estimated. St. George was the fastest-growing metropolitan area in the United States from 2000 to 2005. Utah has the 14th highest median average income and the least income inequality of any U. S. state. A 2012 Gallup national survey found Utah overall to be the "best state to live in" based on 13 forward-looking measurements including various economic and health-related outlook metrics. A common folk etymology is that the name "Utah" is derived from the name of the Ute tribe, purported to mean "people of the mountains" in the Ute language. However, the word for people in Ute is'núuchiu' while the word for mountain is'káav', offering no linguistic connection to the words'Ute' or'Utah'. According to other sources "Utah" is derived from the Apache name "yuttahih" which means "One, Higher up" or "Those that are higher up". In the Spanish language it was said as "Yuta", subsequently the English-speaking people adapted the word "Utah". Thousands of years before the arrival of European explorers, the Ancestral Puebloans and the Fremont people lived in what is now known as Utah, some of which spoke languages of the Uto-Aztecan group.
Ancestral Pueblo peoples built their homes through excavations in mountains, the Fremont people built houses of straw before disappearing from the region around the 15th century. Another group of Native Americans, the Navajo, settled in the region around the 18th century. In the mid-18th century, other Uto-Aztecan tribes, including the Goshute, the Paiute, the Shoshone, the Ute people settled in the region; these five groups were present. The southern Utah region was explored by the Spanish in 1540, led by Francisco Vásquez de Coronado, while looking for the legendary Cíbola. A group led by two Catholic priests—sometimes called the Dominguez-Escalante Expedition—left Santa Fe in 1776, hoping to find a route to the coast of California; the expedition encountered the native residents. The Spanish made further explorations in the region, but were not interested in colonizing the area because of its desert nature. In 1821, the year Mexico achieved its independence from Spain, the region became known as part of its territory of Alta California.
European trappers and fur traders explored some areas of Utah in the early 19th century from Canada and the United States. The city of Provo, Utah was named for one, Étienne Provost, who visited the area in 1825; the city of Ogden, Utah was named after Peter Skene Ogden, a Canadian explorer who traded furs in the Weber Valley. In late 1824, Jim Bridger became the first known English-speaking person to sight the Great Salt Lake. Due to the high salinity of its waters, He thought. After the discovery of the lake, hundreds of American and Canadian traders and trappers established trading posts in the region. In the 1830s, thousands of migrants traveling from the Eastern United States to the American West began to make stops in the region of the Great Salt Lake known as Lake Youta. Following the death of Joseph Smith in 1844, Brigham Young, as president of the Quorum of the Twelve, became the effective leader of the LDS Church in Nauvoo, Illinois. To address the growing conflicts between his people and their neighbors, Young agreed with Illinois Governor Thomas Ford in October 1845 that the Mormons would leave by the following year.
Young and the first band of Mormon pioneers reached the Salt Lake Valley on July 24, 1847. Over the next 22 years, more than 70,000 pioneers settled in Utah. For the first few years, Brigham Young and the thousands of early settlers of Salt Lake City struggled to survive; the arid desert land was deemed by the Mormons as desirable as a place where they could practice their religion without harassment. The Mormon settlements provided pioneers for other settlements in the West. Salt Lake City became the hub of a "far-flung commonwealth" of Mormon settlements. With new church converts coming from the East and around the world, Church leaders assigned groups of church members as missionaries to establish other settlements throughout the West, they developed irrigation to support large pioneer populations along Utah's Wasatch front. Throughout the remainder of the 19th century, Mormon pioneers established hundreds of other settlements in Utah, Id
