At first it was a natural barrier to the West.  In addition, with the Ordinance of 1763 "pioneers" were banned from the Ohio Valley.  Following the American Revolution, westward movement was once again encouraged -- the birth of Manifest Destiny.  When Andrew Jackson won the Battle of New Orleans in 1819, the port was freed from the French and the Mississippi became a major waterway for trade and transportation, thus opening the areas to the west of it for greater settlement.  With that, Manifest Destiny was in full swing.

Yes, they migrate south, along the thermal currents rising from the highlands of New England, down to Hawk Mountain in Pennsylvania. They continue riding these thermals down the Appalachians to the southeast then west to Texas and into Mexico and Central America. They often migrate in large groups, spiraling up and down - it's an awesome sight!

That's a great question to ask, and historians have been debating that one for some time.  A good historian to look into on this is Thomas Dublin (who, incidentally, is a really cool professor and for a well-regarded scholar has very little ego), who did a lot of early work on this topic.  \n\nI personally would say benefit.  Certainly the mill girls gained experiences that they never would have had otherwise and made money.  They also in many cases found husbands in the area.  They were taken care of, did not fall prey to rogues and scammers, and did get intellectual benefits as well. They even put out their own newsletter and worked together for economic justice and gains.

It was for colonization.  People were wanting to move farther into the country and they were mostly farmers.

It was kind of  quiet up there with a few Russian settlements and a lot of coastal indian tribes eking out a living by fishing - or hunting in the mountains. A few Spanish horses had migrated into the area and the Indians were becoming more mobile. Then around 1805. There was the rare whaling vessel that put into Oregon or Washington bays. From 1805 it was a matter of only a few years before the mountain men came in. following them were settlers. In the meantime the Indian populations shrank from european diseases.  As of 1840 there was still no gold rush - it was a slow and steady settlement. There was some testing of rights by British, Russian and American interests, but the Americans took control faster.

The word Mississippi comes from the Ojibwa name for the river, "Messipi" (or Misi-ziibi in contemporary spelling), which means great river, or from the Algonquin Missi Sepe, "great river," poetically, "father of waters." The Ojibwe called Lake Itasca Omashkoozo-zaaga'igan (Elk Lake) and the river flowing out of it Omashkoozo-ziibi (Elk River). After flowing into Lake Bemidji, the Ojibwe called the river Bemijigamaa-ziibi (River from the Traversing Lake). After flowing into Cass Lake, the name of the river again changed to Miskwaawaakokaa-ziibi (Red Cedar River) and then to Gichi-ziibi (Big River) after flowing into Lake Winnibigoshish. The Ojibwe name Misi-ziibi applied only to the portion below the Crow Wing River, but the ever-changing names of the river seemed illogical to the English speakers, so after the expedition by Henry Schoolcraft, the longest stream above the juncture of the Crow Wing River and Gichi-ziibi was named "Mississippi River".

River morphology (shape) is controlled by a number of characteristics. River channels can be broken into three types, straight rivers, single channel meandering rivers, and braided rivers (multi-channel). The amount and size of the sediment the river carries, the slope of the river channel, and the amount of water in the river determine the shape of the river channel. \n\nStraight rivers tend to have the lowest sediment load and the lowest slope. Meandering rivers have slightly more slope, and much more sediment load, and braided rivers have both the highest slopes and greatest sediment loads. \n\nRiver channels in cross section often have a cup-like  shape with the deepest portion, known as the thalweg, found on one side or the other. This thalweg has the highest flow velocity and because it flows faster it can cut into the bank it is closest to, while the shallow part of the river slows down and drops sediment. This action causes both meandering rivers and braided rivers to move their channels from side to side in a valley over time. Straight channel rivers also have thalwegs that move but the effect is much less. \n\nAs rivers go from mountainous terrain to nearly flat valleys they change from braided streams and rivers to meandering rivers. As they approach sea level they form deltas where the flow often separates into separate branching channels. A great deal of the sediment load of the river is deposited on the delta, and as the river flows into the ocean it builds the delta outward. Rivers like the Mississippi have built deltas far out into the ocean with sediment piles that are several miles deep.

Trekboers and migrations\n- as noted earlier, some white farmers had taken to pastoralism as their main economic activity about the beginning of the 18th C. They had developed the tradition that if they needed more or better land, moving farther was the way to acquire it. These treks or journeys were undertaken by small groups or families.\n\n- by the early 19th C, these treks had ceased because of\n\n    * confrontation with the Xhosa to the east;\n    * a law by British authorities in Cape Town forbidding migration north of the Orange River.\n\n- for reasons we shall discuss, a series of coordinated, large treks were undertaken beginning in 1837. These collectively came to be called ‘The Great Trek’. Traditionally, it was said to have ended in 1847 (the bulk of the migration happened in the first years up to 1840), although small scale migration continued afterwards.\n- for a short article on the suedafrika site, see .... Great Trek\n- one estimate is that 6,000 whites left the Cape Colony up to 1840 (the suedafrika article says about 10,000 during the entire period of the Great Trek). Another estimate is that over 15,000 people in total left in that period; however, this includes non-whites who made up at least half of the total. Although they are given little recognition in the Afrikaner nationalist hagiography, a great many servants and employees (mostly Coloureds) also were part of the ‘Great Trek’. One reason for the designation ‘great’ is this size and scale of the migration.\n\n- later, as Afrikaner identity and nationalism began to grow, this series of events (including the battles with various indigenous peoples), came to be regarded as an heroic and defining moment in the history of the Afrikaner ‘nation’. The white participants began to be regarded as larger-than-life heroes who had preserved the Afrikaner ‘nation’ from Anglicization and assimilation. They came to be called ‘Voortrekkers’ meaning those trekkers who went before—i.e., the first Afrikaner nationalists. They have tended to be venerated (like saints or like Americans regard their ‘founding fathers’).\n\n- as noted, the Great Trek was composed of a number of individual ‘treks’. The latter were a bit like wagon trains during the 19th C in the U.S. Some treks had several hundred white people, at least an equal number of servants, large numbers of ox wagons (bigger and much heavier than ‘prairie schooners’ in the U.S.), and huge herds of cattle and livestock. Most treks were organised by and around a particular leader. Moreover, as was shown repeatedly over the next 30 years or so, loyalty was usually to individual leaders rather than to the mystical entity, the ‘nation’.\n\nInterpretations\n- the Great Trek has been the subject of disparate interpretations.\n\n   1. Flight from bondage in the land of Egypt\n      - this was the line taken by the Voortrekkers themselves. They complained of a number of grievances and ‘injustices’ under British rule. The list was long: the Black circuit, Slaughter’s Nek, anglicization policies, immoral and impious overturning of divine order by imposing equality between ‘Christians’ and ‘heathens’, the abolition of slavery with inadequate compensation, maligning of Boers by missionaries and other malicious persons, refusal to allow all cattle and land confiscations from Xhosa in the wars that whites argued were their due, etc.). The government in Cape Town was likened to the government of the pharaohs.\n\n   2. Meddling busybodies and do-gooders in London\n      - this was the line taken by the British settlers and the ‘settler’ school of historians who had their own axes to grind.\n      - the Great Trek was seen as the consequences of the pernicious influence of Exeter Hall (this was the auditorium in London where the anti-slavery organisations and Aborigines Protection Society held their large rallies and meetings) and the meddling of ignorant do-gooders in White

the missisippi doesnt normally but it has before. sometime in the early 1900's (i cant remember when) a large earthquake, i think in the mossouri region, actually shifted the earths crust enough for it to run backwards for a short time. this was isolated however and has only happened once in recorded history

The headwaters for a stream may start at relatively high elevations fed by ice cold snow melt and springs.  Velocity is greatest moving down a mountain slope and purity may also be greatest in runoff water.  Further downstream, the velocity may be less due to a smaller gradient but volume may increase because of tributaries and additional springs.  Mineral contant may increase downstream because of contributions from groundwater.  Sediment and silt may become finer downstream due to less gradient and veloocity.  Temperature may increase downstream because of solar energy heating inflow.  Biological load may increase downstream as the stream passes fertile terrain with organic matter including decayed materials.  Polution may increase downstream because of the influence of man including farms and factories and municipal sewage treatment outflows.

People migrate for economic reasons, better livelihood, better healthcare, better education, basically progression in life.\n\nThe advantage is that people send money home and people develop new skills abroad that may better the people

Also called "misfit river"--river is much smaller than expected for the width of its valleys--very common in areas that were once glaciated.  \nIn the United States and Canada, several rivers are much smaller now  than when they  received vast outflow of water from glacial melts during the Ice Ages when there were vast continental glaciers covering Canada and the Great Lakes area. So, during Pleistocene time, the river systems cut wide valleys that seem not to "fit" the current volume of water flowing through the rivers. \nMinnesota River: "Some 9,000 to 12,000 years ago, the Glacial River Warren flowed with great volumes of meltwater from the southern end of the Glacial Lake Agassiz. Those icy currents carved the wide, trough-like, loam-covered valley of the Minnesota River that we see today."\nhttp://www.environmentaleducationohio.org/Biosphere/Case%20Studies/minnesota.html\nMilk River: "Most of the canyon cutting took place when virtually all of the runoff from southwestern Alberta was being diverted into the Milk River as a result of blockage by ice of drainage to the northeast. With recession of the Laurentide glacier out of the region and opening of a route around the Cypress Hills, evolution of the modern South Saskatchewan drainage began, waters that previously were feeding the Milk River became incorporated into the Hudson Bay catchment basin" (Beaty, 1975)." http://www.uleth.ca/vft/milkriver/milk_river.html\nIllinois River:"the old valley is exceptionally wide for the size of the new river. After the last glacier retreat ed, the Illinois permanently shrank to a much smaller river, fed only by rainfall and seepage from underground aquifers. The pulse of the river changed. In years with average rainfall, backwater lakes rose and expanded, temporary ponds developed, and grass lands became marshes in late winter and early spring. The water then drained out slowly; by midsummer the river flowed only in the main channel and much of the floodplain was dry again. "\nhttp://dnr.state.il.us/orep/c2000/assessments/lower_sangamon/page4.htm.\nUpper Mississippi River.\n\nYou can imagine drought, stream capture, and similar phenomenon causing a decline in flow.

When the river enters the sea carrying with it a lot of water,  many minerals and chemicals dissolved in it, a large amount of gravel and sand are deposited in the course of the river. The  river spreads into a vast area and and its velocity and force is reduced and a large amount of sand is deposited in the  estuary.  With the accumulation of the sand and the minerals the height of the shore is raised and the river is prevented from entering the sea and stagnates. With the weight of more and more deposits of sand and other particles sediments are formed and block the entrance to sea.

I am a petroleum engineer and i will answer u from my experience:(2 months....... ;))\n\n-Long distance of travel= More rounded and well sorted\n-short distance= more angular and less sorted\n\nTravelling agent:\n-Rivers= very small grained rocks at the end of the river...and coarser grains while approaching the begin of the river....due to settling\n\n-Wind=fine grain (Sand size) but more angular\n\n- Waves= The same effect like rivers but coarser grains at shores due to harsh environment...very fine at overseas and deep depths due to very calm water there so small particels can settle........ \n\nBye..hope that i did not forget something..and hope to contact u for overseas friendship......;)
