City
–
A city is a large and permanent human settlement. Cities generally have complex systems for sanitation, utilities, land usage, housing, a big city or metropolis usually has associated suburbs and exurbs. Such cities are associated with metropolitan areas and urban areas. Once a city expands far enough to another city, this region can be deemed a conurbation or megalopolis. Damascus is arguably the oldest city in the world, in terms of population, the largest city proper is Shanghai, while the fastest-growing is Dubai. There is not enough evidence to assert what conditions gave rise to the first cities, some theorists have speculated on what they consider suitable pre-conditions and basic mechanisms that might have been important driving forces. The conventional view holds that cities first formed after the Neolithic revolution, the Neolithic revolution brought agriculture, which made denser human populations possible, thereby supporting city development. The advent of farming encouraged hunter-gatherers to abandon nomadic lifestyles and to settle near others who lived by agricultural production, the increased population density encouraged by farming and the increased output of food per unit of land created conditions that seem more suitable for city-like activities. In his book, Cities and Economic Development, Paul Bairoch takes up position in his argument that agricultural activity appears necessary before true cities can form. According to Vere Gordon Childe, for a settlement to qualify as a city, it must have enough surplus of raw materials to support trade and a relatively large population. To illustrate this point, Bairoch offers an example, Western Europe during the pre-Neolithic, when the cost of transport is taken into account, the figure rises to 200,000 square kilometres. Bairoch noted that this is roughly the size of Great Britain, the urban theorist Jane Jacobs suggests that city formation preceded the birth of agriculture, but this view is not widely accepted. In his book City Economics, Brendan OFlaherty asserts Cities could persist—as they have for thousands of years—only if their advantages offset the disadvantages, OFlaherty illustrates two similar attracting advantages known as increasing returns to scale and economies of scale, which are concepts usually associated with businesses. Their applications are seen in more basic economic systems as well, increasing returns to scale occurs when doubling all inputs more than doubles the output an activity has economies of scale if doubling output less than doubles cost. To offer an example of these concepts, OFlaherty makes use of one of the oldest reasons why cities were built, in this example, the inputs are anything that would be used for protection and the output is the area protected and everything of value contained in it. OFlaherty then asks that we suppose the protected area is square, the advantage is expressed as, O = s 2, where O is the output and s stands for the length of a side. This equation shows that output is proportional to the square of the length of a side, the inputs depend on the length of the perimeter, I =4 s, where I stands for the quantity of inputs. So there are increasing returns to scale, O = I2 /16 and this equation shows that with twice the inputs, you produce quadruple the output

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

ZIP Code
–
ZIP Codes are a system of postal codes used by the United States Postal Service since 1963. The term ZIP, an acronym for Zone Improvement Plan, was chosen to suggest that the travels more efficiently, and therefore more quickly. The basic format consists of five numerical digits, an extended ZIP+4 code, introduced in 1983, includes the five digits of the ZIP Code, a hyphen, and four additional digits that determine a more specific location within a given ZIP Code. The term ZIP Code was originally registered as a servicemark by the U. S. Postal Service, USPS style for ZIP is all caps and the c in code is also capitalized, although style sheets for some publications use sentence case or lowercase. The early history and context of postal codes began with postal district/zone numbers, the United States Post Office Department implemented postal zones for numerous large cities in 1943. For example, Mr. John Smith 3256 Epiphenomenal Avenue Minneapolis 16, by the early 1960s a more organized system was needed, and on July 1,1963, non-mandatory five-digit ZIP Codes were introduced nationwide. Three months later, on October 1,1963, the U. S, an earlier list in June had proposed capitalized abbreviations ranging from two to five letters. The abbreviations have remained unchanged, with one exception, according to the historian of the U. S. Robert Moon, an employee of the post office, is considered the father of the ZIP Code, he submitted his proposal in 1944 while working as a postal inspector. The post office gives credit to Moon only for the first three digits of the ZIP Code, which describe the sectional center facility or sec center, an SCF is a central mail processing facility with those three digits. The SCF sorts mail to all post offices with those first three digits in their ZIP Codes, the mail is sorted according to the final two digits of the ZIP Code and sent to the corresponding post offices in the early morning. Sectional centers do not deliver mail and are not open to the public, Mail picked up at post offices is sent to their own SCF in the afternoon, where the mail is sorted overnight. The United States Post Office used a character, which it called Mr. ZIP. He was often depicted with a such as USE ZIP CODE in the selvage of panes of stamps or on labels contained in, or the covers of. In 1983, the U. S. Postal Service introduced an expanded ZIP Code system that it called ZIP+4, often called plus-four codes, add-on codes, or add ons. But initial attempts to promote use of the new format met with public resistance. For Post Office Boxes, the rule is that each box has its own ZIP+4 code. However, there is no rule, so the ZIP+4 Code must be looked up individually for each box. It is common to use add-on code 9998 for mail addressed to the postmaster,9999 for general delivery, for a unique ZIP Code, the add-on code is typically 0001

Minneapolis
–
Minneapolis is the county seat of Hennepin County, and the larger of the Twin Cities, the 16th-largest metropolitan area in the United States. As of 2015, Minneapolis is the largest city in the state of Minnesota, Minneapolis and Saint Paul anchor the second-largest economic center in the Midwest, after Chicago. Minneapolis lies on both banks of the Mississippi River, just north of the confluence with the Minnesota River, and adjoins Saint Paul. It was once the worlds flour milling capital and a hub for timber, the city and surrounding region is the primary business center between Chicago and Seattle, with Minneapolis proper containing Americas fifth-highest concentration of Fortune 500 companies. As an integral link to the economy, Minneapolis is categorized as a global city. Noted for its music and performing arts scenes, Minneapolis is home to both the award-winning Guthrie Theater and the historic First Avenue nightclub. The name Minneapolis is attributed to Charles Hoag, the citys first schoolteacher, who combined mni, a Dakota Sioux word for water, and polis, Dakota Sioux had long been the regions sole residents when French explorers arrived around 1680. For a time relations were based on fur trading, gradually more European-American settlers arrived, competing for game and other resources with the Dakota. In the early 19th century, the United States acquired this territory from France, fort Snelling was built in 1819 by the United States Army, and it attracted traders, settlers and merchants, spurring growth in the area. The United States government pressed the Mdewakanton band of the Dakota to sell their land, the Minnesota Territorial Legislature authorized present-day Minneapolis as a town in 1856 on the Mississippis west bank. Minneapolis incorporated as a city in 1867, the rail service began between Minneapolis and Chicago. It later joined with the city of St. Anthony in 1872. Minneapolis developed around Saint Anthony Falls, the highest waterfall on the Mississippi River, forests in northern Minnesota were a valuable resource for the lumber industry, which operated seventeen sawmills on power from the waterfall. By 1871, the west river bank had twenty-three businesses, including mills, woolen mills, iron works, a railroad machine shop, and mills for cotton, paper, sashes. Due to the hazards of milling, six local sources of artificial limbs were competing in the prosthetics business by the 1890s. The farmers of the Great Plains grew grain that was shipped by rail to the citys thirty-four flour mills, a father of modern milling in America and founder of what became General Mills, Cadwallader C. Some ideas were developed by William Dixon Gray and some acquired through industrial espionage from the Hungarians by William de la Barre, pillsbury Company across the river were barely a step behind, hiring Washburn employees to immediately use the new methods. The hard red spring wheat that grows in Minnesota became valuable, not until later did consumers discover the value in the bran that Minneapolis

Sioux
–
The Sioux /ˈsuː/ are groups of Native American tribes and First Nations peoples in North America. The term can refer to any group within the Great Sioux Nation or to any of the nations many language dialects. The Sioux comprise three major divisions based on divisions, the Dakota, Lakota, and Nakota. The Santee Dakota reside in the extreme east of the Dakotas, Minnesota, the Yankton and Yanktonai Dakota, collectively also referred to by the endonym Wičhíyena, reside in the Minnesota River area. They are considered to be the middle Sioux, and have in the past been erroneously classified as Nakota, the actual Nakota are the Assiniboine and Stoney of Western Canada and Montana. The Lakota, also called Teton, are the westernmost Sioux, known for their hunting, the name Sioux was adopted in English by the 1760s from French. It is abbreviated from Nadouessioux, first attested by Jean Nicolet in 1640, the name is sometimes said to be derived from an Ojibwe exonym for the Sioux meaning little snakes. The spelling in -x is due to the French plural marker, the Proto-Algonquian form *na·towe·wa, meaning Northern Iroquoian, has reflexes in several daughter languages that refer to a small rattlesnake. An alternative explanation is derivation from an exonym na·towe·ssiw, from a verb meaning to speak a foreign language. The current Ojibwe term for the Sioux and related groups is Bwaanag, presumably, this refers to the style of cooking the Sioux used in the past. The alternative English spelling of Ogallala is considered improper, the historical Sioux referred to the Great Sioux Nation as the Očhéthi Šakówiŋ, meaning Seven Council Fires. Each fire was a symbol of an oyate, the seven nations that comprise the Sioux are, Bdewákaŋthuŋwaŋ, Waȟpéthuŋwaŋ, Waȟpékhute, Sisíthuŋwaŋ, the Iháŋkthuŋwaŋ, Iháŋkthuŋwaŋna, and the Thítȟuŋwaŋ. The Seven Council Fires would assemble each summer to hold council, renew kinships, decide tribal matters, the seven divisions would select four leaders known as Wičháša Yatápika from among the leaders of each division. The last meeting of the Seven Council Fires was in 1850, today the Teton, Santee and the Minnesota Dakota, and Yankton/Yanktonai are usually known, respectively, as the Lakota, Eastern Dakota, or Western Dakota. In any of the three dialects, Lakota or Dakota translate to mean friend or ally, referring to the alliance that once bound the Great Sioux Nation. The Dakota are first recorded to have resided at the source of the Mississippi River during the seventeenth century, by 1700 some had migrated to present-day South Dakota. Late in the 17th century, the Dakota entered into an alliance with French merchants, the French were trying to gain advantage in the struggle for the North American fur trade against the English, who had recently established the Hudsons Bay Company. The first recorded encounter between the Sioux and the French occurred when Radisson and Groseilliers reached what is now Wisconsin during the winter of 1659–60

U.S. Route 212
–
U. S. Route 212 is a spur of U. S. Route 12. It does not intersect U. S.12 now, but it once had a terminus at U. S.12 in St. Paul. It runs for 949 miles from Minnesota Highway 62 at Edina, U. S.212 passes through the states of Minnesota, South Dakota, Wyoming, and Montana. It goes through the cities of Watertown, South Dakota and Billings, the western terminus of Highway 212 is at the Montana/Wyoming state line within Yellowstone National Park. Within the park it is contiguous with Northeast Entrance Road, which has its terminus on the Grand Loop within the Wyoming portion of the park. Highway 212 passes through Cooke City, Montana, then crosses the Wyoming state line, the section of Highway 212 between Cooke City and Red Lodge is known as the Beartooth Highway. Rising to an elevation of 10,974 feet above sea level at Beartooth Pass, in his book Dateline America published in 1979, the late CBS correspondent Charles Kuralt referred to the highway as the most beautiful drive in America. Running northeast from the Beartooth Mountains, Highway 212 joins U. S. Route 310 before passing into the town of Laurel, here Highway 212 joins Interstate 90 eastbound, while Highway 310 ends. Together, Highway 212 and I-90 run east through Billings, Montana to the town of Crow Agency, within the Crow Indian Reservation, Highway 212 leaves I-90 and runs east and southeast through the high plains of Montana. It is the main east–west road through the Northern Cheyenne Indian Reservation, southeast of Alzada, Montana, Highway 212 recrosses the Wyoming state line, after about 20.3 miles, Highway 212 enters South Dakota. For the entire length of Highway 212 in Montana between I-90 and the Wyoming state line, it is known as the Warrior Trail Highway. Highway 212 enters South Dakota near the junction of the Montana, Wyoming and South Dakota state lines, here it intersects with U. S Route 85, and then continues eastward, skirting the southern end of the Belle Fourche Reservoir. It continues east, passing the town of Nisland, until connecting with SD-79 south of Newell and it runs north into Newell, then turns generally east again, passing through the town of Faith and entering the Cheyenne River Indian Reservation. It then passes through Dupree and North Eagle Butte, finally crossing the Missouri River, continuing east, it then intersects with U. S. Route 83 near Gettysburg, and then continues eastward, passing through Gettysburg and Faulkton. It intersects with SD-45, where it is cosigned for a southern leg, before turning eastward again and passing through Rockham, Zell and Redfield. Continuing east, it passes through Clark, before entering Watertown, just east of Watertown, it intersects with Interstate 29, and continues east to the Minnesota state line. Legally, the South Dakota section of U. S.212 is defined at South Dakota Codified Laws § 31-4-206, the 160 miles of US212 in Minnesota are officially designated Minnesota Veterans Memorial Highway. Yellowstone Trail is the name designation for this same stretch of US212 from the auto trail days

Marriage
–
The definition of marriage varies according to different cultures, but it is principally an institution in which interpersonal relationships, usually sexual, are acknowledged. In some cultures, marriage is recommended or considered to be compulsory before pursuing any sexual activity, when defined broadly, marriage is considered a cultural universal. Individuals may marry for several reasons, including legal, social, libidinal, emotional, financial, spiritual, whom they marry may be influenced by socially determined rules of incest, prescriptive marriage rules, parental choice and individual desire. In some areas of the world, arranged marriage, child marriage, polygamy, conversely, such practices may be outlawed and penalized in parts of the world out of concerns for womens rights and because of international law. These trends coincide with the human rights movement. Marriage can be recognized by a state, an organization, an authority, a tribal group. It is often viewed as a contract, Marriages can be performed in a secular civil ceremony or in a religious setting via a wedding ceremony. The act of marriage usually creates normative or legal obligations between the individuals involved, and any offspring they may produce, some cultures allow the dissolution of marriage through divorce or annulment. In some areas, child marriages and polygamy may occur in spite of laws against the practice. For example, the number of marriages in Europe decreased by 30% from 1975 to 2005 and these changes have occurred primarily in Western countries. The word marriage derives from Middle English mariage, which first appears in 1250–1300 CE and this in turn is derived from Old French, marier, and ultimately Latin, marītāre, meaning to provide with a husband or wife and marītāri meaning to get married. The adjective marīt-us -a, -um meaning matrimonial or nuptial could also be used in the form as a noun for husband. Anthropologists have proposed several competing definitions of marriage in an attempt to encompass the wide variety of marital practices observed across cultures, even within Western culture, definitions of marriage have careened from one extreme to another and everywhere in between. The anthropological handbook Notes and Queries defined marriage as a union between a man and a such that children born to the woman are the recognized legitimate offspring of both partners. In recognition of a practice by the Nuer people of Sudan allowing women to act as a husband in certain circumstances, Kathleen Gough suggested modifying this to a woman, none of these men had legal rights to the womans child. Economic anthropologist Duran Bell has criticized the definition on the basis that some societies do not require marriage for legitimacy. He argued that a definition of marriage is circular in societies where illegitimacy has no other legal or social implications for a child other than the mother being unmarried. In 1955 article in Man, Leach argued that no one definition of marriage applied to all cultures and he offered a list of ten rights associated with marriage, including sexual monopoly and rights with respect to children, with specific rights differing across cultures

Public Land Survey System
–
The Public Land Survey System is the surveying method developed and used in the United States to plat, or divide, real property for sale and settling. Beginning with the Seven Ranges, in present-day Ohio, the PLSS has been used as the survey method in the United States. Following the passage of the Northwest Ordinance, in 1787, the Surveyor General of the Northwest Territory platted lands in the Northwest Territory. The Surveyor General was later merged with the General Land Office, today, the BLM controls the survey, sale, and settling of the new lands, and manages the State Plane Coordinate System. The government wished both to land to Revolutionary War soldiers in reward for their services, as well as to sell land as a way of raising money for the nation. Before this could happen, the land needed to be surveyed, the Land Ordinance of 1785 marks the beginning of the Public Land Survey System. The Continental Congress was deeply in debt following the Declaration of Independence, with little power to tax, the federal government decided to use the sale of the Western Territories to pay off American Revolutionary War debt. The original colonies continued the British system of metes and bounds and this system describes property lines based on local markers and bounds drawn by humans, often based on topography. Particularly in New England, this system was supplemented by drawing town plats, the metes-and-bounds system was used to describe a town of a generally rectangular shape,4 to 6 miles on a side. Within this boundary, a map or plat was maintained that all the individual lots or properties. There are some difficulties with this system, Irregular shapes for properties make for more complex descriptions. Over time, these descriptions become problematic as trees die or streams move by erosion and it wasnt useful for the large, newly surveyed tracts of land being opened in the west, which were being sold sight unseen to investors. In addition this system didnt work there were already people on the ground to maintain records. In the 1783 Treaty of Paris recognizing the United States, Britain also recognized American rights to the south of the Great Lakes. The Continental Congress passed the Land Ordinance of 1785 and then the Northwest Ordinance in 1787 to control the survey, sale, the original 13 colonies donated their western lands to the new Union, for the purpose of giving land for new states. These include the lands formed the Northwest Territory, Kentucky, Tennessee, Alabama. The state that gave up the most was Virginia, whose original claim included most of the Northwest Territory and Kentucky, the first surveys under the new rectangular system were in eastern Ohio in an area called the Seven Ranges. The Beginning Point of the U. S, Public Land Survey is located at a point on the Ohio-Pennsylvania border between East Liverpool, Ohio and the Pittsburgh metropolitan area, on private property

Precipitation
–
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, rain, sleet, snow, graupel, Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and precipitates. Thus, fog and mist are not precipitation but suspensions, because the vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated, Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers, moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain. This process is active when freezing rain is occurring. A stationary front is often present near the area of freezing rain, provided necessary and sufficient atmospheric moisture content, the moisture within the rising air will condense into clouds, namely stratus and cumulonimbus. Eventually, the droplets will grow large enough to form raindrops. Lake-effect snowfall can be locally heavy, thundersnow is possible within a cyclones comma head and within lake effect precipitation bands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation, on the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. The movement of the trough, or intertropical convergence zone. Precipitation is a component of the water cycle, and is responsible for depositing the fresh water on the planet. Approximately 505,000 cubic kilometres of water falls as precipitation each year,398,000 cubic kilometres of it over the oceans and 107,000 cubic kilometres over land. Given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres, Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Precipitation may occur on celestial bodies, e. g. when it gets cold, Mars has precipitation which most likely takes the form of frost. Precipitation is a component of the water cycle, and is responsible for depositing most of the fresh water on the planet. Approximately 505,000 km3 of water falls as precipitation each year,398,000 km3 of it over the oceans, given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres. Mechanisms of producing precipitation include convective, stratiform, and orographic rainfall, Precipitation can be divided into three categories, based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or ice

Population density
–
Population density is a measurement of population per unit area or unit volume, it is a quantity of type number density. It is frequently applied to living organisms, and most of the time to humans and it is a key geographical term. Population density is population divided by land area or water volume. Low densities may cause a vortex and lead to further reduced fertility. This is called the Allee effect after the scientist who identified it, commonly this may be calculated for a county, city, country, another territory, or the entire world. The worlds population is around 7,000,000,000, therefore, the worldwide human population density is around 7,000,000,000 ÷510,000,000 =13.7 per km2. If only the Earths land area of 150,000,000 km2 is taken into account and this includes all continental and island land area, including Antarctica. If Antarctica is also excluded, then population density rises to over 50 people per km2, thus, this number by itself does not give any helpful measurement of human population density. Several of the most densely populated territories in the world are city-states, microstates, cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Most of the most densely populated cities are in Southeast Asia, though Cairo, for instance, Milwaukee has a greater population density when just the inner city is measured, and the surrounding suburbs excluded. Arithmetic density, The total number of people / area of land, physiological density, The total population / area of arable land. Agricultural density, The total rural population / area of arable land, residential density, The number of people living in an urban area / area of residential land. Urban density, The number of people inhabiting an urban area / total area of urban land, ecological optimum, The density of population that can be supported by the natural resources. S.

Hennepin County, Minnesota
–
Hennepin County /ˈhɛnəpɪn kaʊnti/ is a county in the U. S. state of Minnesota. As of the 2010 census the population was 1,152,425 and it is the most populous county in Minnesota and the 34th-most populous county in the United States, more than one in five Minnesotans live in Hennepin County. Its county seat is Minneapolis, the states most populous city, the county is named in honor of the 17th-century explorer Father Louis Hennepin. Hennepin County is included in the Minneapolis-St. Paul-Bloomington, MN-WI Metropolitan Statistical Area, the center of population of Minnesota is in Hennepin County, in the city of Minneapolis. Hennepin County was created in 1852 by the Minnesota Territorial Legislature, Father Louis Hennepins name was chosen because he originally named St. Anthony Falls and recorded some of the earliest accounts of the area for the Western world. Hennepin Countys early history is linked to the establishment of the cities of Minneapolis. The history of Hennepin County is cataloged at the Hennepin History Museum, according to the U. S. Census Bureau, the county has a total area of 607 square miles, of which 554 square miles is land and 53 square miles is water. Hennepin is one of 17 Minnesota counties with more savanna soils than prairie or forest soils.
