The Ottawa Valley is the valley of the Ottawa River, along the boundary between Eastern Ontario and Odawa, Canada. The valley is the transition between the Saint Lawrence Lowlands and the Canadian Shield. Because of the surrounding shield, the valley is narrow at its western end, then becomes increasingly wide (mainly on the Southern Ontario side of the river) as it progresses eastward. The underlying geophysical structure is the Ottawa-Bonnechere Graben. Approximately 1.3 million people reside in the valley (''and along its tributaries''), of these the majority, around 80%, reside in Ottawa, the remainder on the north side of the Ottawa River, in Quebec. The total area of the Ottawa Valley is 2.4 million hectares (6 million acres). The National Capital Region area has just over 1.4 million inhabitants in both provinces. Near the city of Ottawa, the Ottawa Valley merges with the St. Lawrence Valley to the south to create a delta of flat farmland stretching unbroken from the Ottawa River to the Saint Lawrence River as far east as the island of Montreal, where the two rivers meet. This area is sometimes referred to as the "Lower Ottawa Valley", in contrast with the "Upper Ottawa Valley" west of Ottawa, but the name is not common, and most people think of the Ottawa Valley as only the upper portion. From west to east, the major Ottawa Valley communities are Mattawa, Deep River (with nearby Chalk River, the site of Canada's nuclear reactor program), Petawawa (a major Canadian military base), Pembroke (where Samuel de Champlain landed briefly), Fort Coulonge, Shawville, Renfrew, Quyon, Arnprior, Ottawa (the nation's capital), Rockland, L'Orignal, Hawkesbury, and Rigaud. ==History== The entire Ottawa Valley is Algonquin traditional territory and, like most populated areas of Canada, is presently under land claim.〔(【引用サイトリンク】title=Algonquin Land Claim Map )〕 As a relatively recent adaptation resulting from the economic pressures of the encroachment of non-native settling of the valley, the Algonquin First Nation is unevenly distributed within their territory. A majority of Algonquins reside on the Quebec side of the border, where all but two Algonquin communities are located.〔(【引用サイトリンク】title=Algonquin Land Claim with Ontario )〕 However, there are many Algonquin communities and individuals not recognized as such by the Government of Canada under the Indian Act. These individuals are referred to as 'Non-Status Indians'. Ardoch Algonquin First Nation is one such community located in the Ottawa Valley fighting for the return of their land. After the arrival of European settlers in North America, the first major industry of the Ottawa Valley was fur trading. The valley was part of the major cross-country route for French-Canadian Voyageurs, who would paddle canoes up the Ottawa River as far as Mattawa and then portage west through various rivers and lakes to Georgian Bay on Lake Huron. Later, lumber became the valley's major industry, and it is still important in the far western part where the valley is narrow and little farmland is available. Today, the vast majority of the valley's residents live at its eastern end in Ottawa and its suburbs, where government and technology are major industries. In the areas of Morrison’s Island and the Allumette Island there were many archaeological sites found from the earlier years of the Algonquin First Nations tribes. Many of these sites were found by the late Clyde C. Kennedy, who was a student of history; he was very interested in history and worked hard while researching the sites. The items found on the different sites are dated from about five thousand years ago to about two thousand years ago, and are a range of different things from native copper, to spear heads. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ottawa Valley」の詳細全文を読む スポンサード リンク
