Black Hawk War
The Black Hawk War was a brief conflict between the United States and Native Americans led by Black Hawk, a Sauk leader. The war erupted soon after Black Hawk and a group of Sauks and Kickapoos, known as the "British Band", crossed the Mississippi River, into the U. S. state of Illinois, from Iowa Indian Territory in April 1832. Black Hawk's motives were ambiguous, but he was hoping to avoid bloodshed while resettling on tribal land, ceded to the United States in the disputed 1804 Treaty of St. Louis. U. S. officials, convinced that the British Band was hostile, mobilized a frontier militia and opened fire on a delegation from the Native Americans on May 14, 1832. Black Hawk responded by attacking the militia at the Battle of Stillman's Run, he led his band to a secure location in what is now southern Wisconsin and was pursued by U. S. forces. Meanwhile, other Native Americans conducted raids against forts and settlements unprotected with the absence of U. S. troops. Some Ho-Chunk and Potawatomi warriors with grievances against European-Americans took part in these raids, although most tribe members tried to avoid the conflict.
The Menominee and Dakota tribes at odds with the Sauks and Meskwakis, supported the U. S. Commanded by General Henry Atkinson, the U. S. troops tracked the British Band. Militia under Colonel Henry Dodge caught up with the British Band on July 21 and defeated them at the Battle of Wisconsin Heights. Black Hawk's band was weakened by hunger and desertion and many native survivors retreated towards the Mississippi. On August 2, U. S. soldiers attacked the remnants of the British Band at the Battle of Bad Axe, killing many or capturing most who remained alive. Black Hawk and other leaders escaped, but surrendered and were imprisoned for a year; the Black Hawk War gave the young captain Abraham Lincoln his brief military service, although he never participated in a battle. Other participants who became famous included Winfield Scott, Zachary Taylor, Jefferson Davis; the war gave impetus to the U. S. policy of Indian removal, in which Native American tribes were pressured to sell their lands and move west of the Mississippi River and stay there.
In the 18th century, the Sauk and Meskwaki Native American tribes lived along the Mississippi River in what are now the U. S. states of Iowa. The two tribes had become connected after having been displaced from the Great Lakes region in conflicts with New France and other Native American tribes after the so-called Fox Wars ended in the 1730s. By the time of the Black Hawk War, the population of the two tribes was about 6,000 people; as the United States expanded westward in the early 19th century, government officials sought to buy as much Native American land as possible. In 1804, territorial governor William Henry Harrison negotiated a treaty in St. Louis in which a group of Sauk and Meskwaki leaders sold their lands east of the Mississippi for more than $2,200, in goods and annual payments of $1,000 in goods; the treaty became controversial because the Native leaders had not been authorized by their tribal councils to cede lands. Historian Robert Owens argued that the chiefs did not intend to give up ownership of the land, that they would not have sold so much valuable territory for such a modest price.
Historian Patrick Jung concluded that the Sauk and Meskwaki chiefs intended to cede a little land, but that the Americans included more territory in the treaty's language than the Natives realized. According to Jung, the Sauks and Meskwakis did not learn the true extent of the cession until years later; the 1804 treaty allowed the tribes to continue using the ceded land until it was sold to American settlers by the U. S. government. For the next two decades, Sauks continued to live at Saukenuk, their primary village, located near the confluence of the Mississippi and Rock Rivers. In 1828, the U. S. government began to have the ceded land surveyed for white settlement. Indian agent Thomas Forsyth informed the Sauks that they should vacate Saukenuk and their other settlements east of the Mississippi; the Sauks were divided about. Most Sauks decided to relocate west of the Mississippi rather than become involved in a confrontation with the United States; the leader of this group was Keokuk, who had helped defend Saukenuk against the Americans during the War of 1812.
Keokuk was not a chief, but as a skilled orator, he spoke on behalf of the Sauk civil chiefs in negotiations with the Americans. Keokuk regarded the 1804 treaty as a fraud, but after having seen the size of American cities on the east coast in 1824, he did not think the Sauks could oppose the United States. Although the majority of the tribe decided to follow Keokuk's lead, about 800 Sauks—roughly one-sixth of the tribe—chose instead to resist American expansion. Black Hawk, a war captain who had fought against the United States in the War of 1812 and was now in his 60s, emerged as the leader of this faction in 1829. Like Keokuk, Black Hawk was not a civil chief, but he became Keokuk's primary rival for influence within the tribe. Black Hawk had signed a treaty in May 1816 that affirmed the disputed 1804 land cession, but he insisted that what had been written down was different from what had been spoken at the treaty conference. According to Black Hawk, the "whites were in the habit of saying one thing to the Indians and putting another thing down on paper."
Black Hawk was determined to hold onto Saukenuk, where he had been born. When the Sauks returned to the village in 1829 after their annual winter hunt in the west, they found that it had been occupied by white squatters who were anticipating the sale of
Time in the United States
Time in the United States, by law, is divided into nine standard time zones covering the states and its possessions, with most of the United States observing daylight saving time for the spring and fall months. The time zone boundaries and DST observance are regulated by the Department of Transportation. Official and precise timekeeping services are provided by two federal agencies: the National Institute of Standards and Technology; the clocks run by these services are kept synchronized with each other as well as with those of other international timekeeping organizations. It is the combination of the time zone and daylight saving rules, along with the timekeeping services, which determines the legal civil time for any U. S. location at any moment. Before the adoption of four standard time zones for the continental United States, many towns and cities set their clocks to noon when the sun passed their local meridian, pre-corrected for the equation of time on the date of observation, to form local mean solar time.
Noon occurred at different times but time differences between distant locations were noticeable prior to the 19th century because of long travel times and the lack of long-distance instant communications prior to the development of the telegraph. The use of local solar time became awkward as railways and telecommunications improved. American railroads maintained many different time zones during the late 1800s; each train station set its own clock making it difficult to coordinate train schedules and confusing passengers. Time calculation became a serious problem for people traveling by train, according to the Library of Congress; every city in the United States used a different time standard so there were more than 300 local sun times to choose from. Time zones were therefore a compromise, relaxing the complex geographic dependence while still allowing local time to be approximate with mean solar time. Railroad managers tried to address the problem by establishing 100 railroad time zones, but this was only a partial solution to the problem.
Weather service chief Cleveland Abbe had needed to introduce four standard time zones for his weather stations, an idea which he offered to the railroads. Operators of the new railroad lines needed a new time plan that would offer a uniform train schedule for departures and arrivals. Four standard time zones for the continental United States were introduced at noon on November 18, 1883, when the telegraph lines transmitted time signals to all major cities. In October 1884, the International Meridian Conference at Washington DC adopted a proposal which stated that the prime meridian for longitude and timekeeping should be one that passes through the centre of the transit instrument at the Greenwich Observatory in the United Kingdom; the conference therefore established the Greenwich Meridian as the prime meridian and Greenwich Mean Time as the world's time standard. The US time-zone system grew from this, in which all zones referred back to GMT on the prime meridian. In 1960, the International Radio Consultative Committee formalized the concept of Coordinated Universal Time, which became the new international civil time standard.
UTC is, within about 1 second, mean solar time at 0°. UTC does not observe daylight saving time. For most purposes, UTC is considered interchangeable with GMT, but GMT is no longer defined by the scientific community. UTC is one of several related successors to GMT. Standard time zones in the United States are defined at the federal level by law 15 USC §260; the federal law establishes the transition dates and times at which daylight saving time occurs, if observed. It is the authority of the Secretary of Transportation, in coordination with the states, to determine which regions will observe which of the standard time zones and if they will observe daylight saving time; as of August 9, 2007, the standard time zones are defined in terms of hourly offsets from UTC. Prior to this they were based upon the mean solar time at several meridians 15° apart west of Greenwich. Only the full-time zone names listed below are official. View the standard time zone boundaries here; the United States uses nine standard time zones.
As defined by US law they are: From east to west, the four time zones of the contiguous United States are: Eastern Time Zone, which comprises the states on the Atlantic coast and the eastern two thirds of the Ohio Valley. Central Time Zone, which comprises the Gulf Coast, Mississippi Valley, most of the Great Plains. Mountain Time Zone, which comprises the states and portions of states that include the Rocky Mountains and the western quarter of the Great Plains. Pacific Time Zone, which comprises the states on the Pacific coast, plus Nevada and the Idaho panhandle. Alaska Time Zone, which comprises most of the state of Alaska. Hawaii-Aleutian Time Zone, which includes Hawaii and most of the length of the Aleutian Islands chain. Samoa Time Zone, which comprises American Samoa. Chamorro Time Zone, which comprises Guam and the Northern Mariana Islands. Atlantic Time Zone, which comprises Puerto Rico and the US Virgin Islands; some United States Minor Outlying Islands are outside the time zones defined by 15 U.

Interstate 90 is an east–west transcontinental freeway, the longest Interstate Highway in the United States at 3,020.54 miles. Its western terminus is in Seattle, at State Route 519 near T-Mobile Park and CenturyLink Field, its eastern terminus is in Boston, at Route 1A near Logan International Airport; the western portion of I-90 crosses the Continental Divide over Homestake Pass just east of Butte, connecting major cities such as Spokane, Washington. Between Seattle and the Wisconsin-Illinois state line, I-90 is a toll-free Interstate. East of that border, much of I-90 follows several toll roads, many of which predate the Interstate Highway system; these include the Jane Addams Memorial Tollway, Chicago Skyway, Indiana Toll Road, Ohio Turnpike, New York State Thruway, the Massachusetts Turnpike. The Interstate is not tolled through some segments in downtown Chicago; the western I-90 terminus is in the SoDo neighborhood of Seattle. I-90 eastbound begins at exit 2B, Edgar Martínez Drive S and 4th Avenue S. I-90 westbound exit 2B ends at Edgar Martínez Dr and 4th Ave near T-Mobile Park, as well as 4th Ave just north of S.
Royal Brougham Way near CenturyLink Field, about a block east of the entrance to the Port of Seattle's container shipping terminal at Pier 46. The tunnel that carries I-90 under the Mount Baker Ridge is on the National Register of Historic Places; the east portal of the tunnel is constructed as a bas relief concrete sculpture. I-90 incorporates two of the longest floating bridges in the world, the Lacey V. Murrow Memorial Bridge and the Homer M. Hadley Memorial Bridge, which cross Lake Washington from Seattle to Mercer Island, they are the fifth longest such bridges, respectively. Forty miles east of Bellevue, I-90 traverses the Cascade Range's Snoqualmie Pass, elevation 3,022 feet, it intersects I-82 shortly after exiting the mountains and crosses the Columbia River on the Vantage Bridge at mile post 137. After entering Spokane near mile post 279, it enters Idaho eighteen miles later. Since 1980, I-90 from Seattle to Thorp was designated the Mountains to Sound Greenway to protect its outstanding scenic and cultural resources.
The Washington section of I-90 is defined in the Revised Code of Washington. The small town of Wallace still prides itself on having what was the last stop light in the Rocky Mountains on I-90, its downtown has many historical buildings, which would have been wiped out by the original planned route of the freeway, so in 1976, city leaders had the downtown placed on the National Register of Historic Places. As a result, the federal government was forced, at great expense, to reroute the freeway to the northern edge of downtown and elevate it; that section of I-90 opened in September 1991. A bicycle path is routed beneath part of that segment. In the period between 1995 and 1999, there was no numbered speed limit on I-90 in Montana; the speed limit was defined as "reasonable and prudent" as determined on a case-by-case basis by the Montana Highway Patrol. The speed limit in Montana is now 80 mph. From the west I-90 enters Montana on the summit of Lookout Pass, it passes next to Missoula and runs through Butte, where it connects with I-15 for close to eight miles, before crossing the continental divide just east of Butte where it goes over Homestake Pass, 6,329 feet in elevation, the highest point for the Interstate.
It passes between the Gallatin and Bridger mountain ranges over Bozeman Pass between Bozeman and Livingston. It follows the Yellowstone River from Livingston to Billings where it connects the suburbs of Laurel and Lockwood with the rest of the Billings area. In Lockwood it turns south. South of Hardin it passes the site of the Battle of the Little Bighorn at Crow Agency on the Crow Indian Reservation. Montana boasts the longest stretch of I-90. I-90 enters the state of Wyoming from the north after splitting off from I-94 in Montana; the first major town is Sheridan. It follows the foothills of the Bighorn Mountains between Sheridan and Buffalo where it intersects with I-25, where the route goes from a north–south orientation to an east–west orientation, it goes across the Powder River Basin toward Gillette and Sundance where it shares alignments with both US 14 and US 16. Near the Black Hills, I-90 leaves Wyoming and enters South Dakota between Sundance and Spearfish, South Dakota where it proceeds southeast toward Rapid City, South Dakota.
Near Rapid City at the Wyoming border I-90 is a four-lane divided highway with a grass median. In the Sioux Falls area, I-90 continues east a short distance to Minnesota. I-90 is the longest east–west thoroughfare in South Dakota; this interstate goes through Mitchell, Sioux Falls, Rapid City. It does not go through the state capital of Pierre; the South Dakota section of I-90 is defined at South Dakota Codified Laws § 31-4-184. The Minnesota section of I-90 is defined as Route 391 in Minnesota Statutes § 161.12. I-90 crosses southern Minnesota from the South Dakota border near Beaver Creek, Minnesota, to the Mississippi River near La Crosse, Wisconsin. On most of its length in the state, it is close to the Iowa border and parallel with it. In southeast Minnesota, it curves north to Winona; the wayside rest area near Blue Earth, Minnesota is where Minnesota's east-building and
2010 United States Census
The 2010 United States Census is the twenty-third and most recent United States national census. National Census Day, the reference day used for the census, was April 1, 2010; the census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired; the population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 Census. This was the first census in which all states recorded a population of over half a million, as well as the first in which all 100 largest cities recorded populations of over 200,000; as required by the United States Constitution, the U. S. census has been conducted every 10 years since 1790. The 2000 U. S. Census was the previous census completed. Participation in the U. S. Census is required by law in Title 13 of the United States Code. On January 25, 2010, Census Bureau Director Robert Groves inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, a resident of Noorvik, Alaska.
More than 120 million census forms were delivered by the U. S. Post Office beginning March 15, 2010; the number of forms mailed out or hand-delivered by the Census Bureau was 134 million on April 1, 2010. Although the questionnaire used April 1, 2010 as the reference date as to where a person was living, an insert dated March 15, 2010 included the following printed in bold type: "Please complete and mail back the enclosed census form today." The 2010 Census national mail participation rate was 74%. From April through July 2010, census takers visited households that did not return a form, an operation called "non-response follow-up". In December 2010, the U. S. Census Bureau delivered population information to the U. S. President for apportionment, in March 2011, complete redistricting data was delivered to states. Identifiable information will be available in 2082; the Census Bureau did not use a long form for the 2010 Census. In several previous censuses, one in six households received this long form, which asked for detailed social and economic information.
The 2010 Census used only a short form asking ten basic questions: How many people were living or staying in this house, apartment, or mobile home on April 1, 2010? Were there any additional people staying here on April 1, 2010 that you did not include in Question 1? Mark all that apply: Is this house, apartment, or mobile home – What is your telephone number? What is Person 1's name? What is Person 1's sex? What is Person 1's age and Person 1's date of birth? Is Person 1 of Hispanic, Latino, or Spanish origin? What is Person 1's race? Does Person 1 sometimes live or stay somewhere else? The form included space to repeat all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, nor was the form available for download. Detailed socioeconomic information collected during past censuses will continue to be collected through the American Community Survey; the survey provides data about communities in the United States on a 1-year or 3-year cycle, depending on the size of the community, rather than once every 10 years.
A small percentage of the population on a rotating basis will receive the survey each year, no household will receive it more than once every five years. In June 2009, the U. S. Census Bureau announced. However, the final form did not contain a separate "same-sex married couple" option; when noting the relationship between household members, same-sex couples who are married could mark their spouses as being "Husband or wife", the same response given by opposite-sex married couples. An "unmarried partner" option was available for couples; the 2010 census cost $13 billion $42 per capita. Operational costs were $5.4 billion under the $7 billion budget. In December 2010 the Government Accountability Office noted that the cost of conducting the census has doubled each decade since 1970. In a detailed 2004 report to Congress, the GAO called on the Census Bureau to address cost and design issues, at that time, had estimated the 2010 Census cost to be $11 billion. In August 2010, Commerce Secretary Gary Locke announced that the census operational costs came in under budget.
Locke credited the management practices of Census Bureau director Robert Groves, citing in particular the decision to buy additional advertising in locations where responses lagged, which improved the overall response rate. The agency has begun to rely more on questioning neighbors or other reliable third parties when a person could not be reached at home, which reduced the cost of follow-up visits. Census data for about 22% of U. S. househol
