Mattawa River
The Mattawa River is a river in central Ontario, Canada. It flows east from Trout Lake east of North Bay and enters the Ottawa River at the town of Mattawa. Counting from the head of Trout Lake, it is 76 km in length. The river's name comes from the Algonquin word for "meeting of waterways". Two provincial parks are located along it: the Mattawa River Provincial Park stretches along both sides of the river's banks for almost its full length; and Samuel de Champlain Provincial Park, located about 10 km from the river's end. Geography The river flows inside a graben through the Algonquin highlands. This valley is an offshoot arm of ancient rift valley, called the Ottawa-Bonnechere Graben, which still causes minor earthquakes in the area.Canadian Heritage Rivers System: Mattawa River fact sheet, Ministry of Natural ResourcesOnline version) From Lake Talon to Mattawa the river flows through a rock-walled canyon up to in places.

Algonquin Language
Algonquin (also spelled Algonkin; in Algonquin: or ) is either a distinct Algonquian language closely related to the Ojibwe language or a particularly divergent Ojibwe dialect. It is spoken, alongside French and to some extent English, by the Algonquin First Nations of Quebec and Ontario. As of 2006, there were 2,680 Algonquin speakers,. less than 10% of whom were monolingual. Algonquin is the language for which the entire Algonquian language subgroup is named; the similarity among the names often causes considerable confusion. Like many Native American languages, it is strongly verb-based, with most meaning being incorporated into verbs instead of using separate words for prepositions, tense, etc. Classification Omà mìwininìmowin (Algonquin) is an Algonquian language, of the Algic family of languages, and is descended from Proto-Algonquian. It is considered a particularly divergent dialect of Ojibwe by many. But, although the speakers call themselves '' Omà mìwininà ...

Ottawa-Bonnechere Graben
The Ottawa-Bonnechere Graben (also known as the Ottawa Graben) is a geological structure that coincides with a wide topographic depression extending from near Montréal through Ottawa. It is part of the Saint Lawrence rift system that also includes the seismically active Saguenay graben. This rift valley was formed when the Earth's crust moved downward about a kilometre between two major fault zones known as the Mattawa and Petawawa faults. Geography The Ottawa-Bonnechere Graben measures about , running from the Montreal area on the east to near Sudbury and Lake Nipissing on the west. On the east, it joins the Saint Lawrence rift system, a half-graben which extends more than 1000 km along the Saint Lawrence River valley and links the Ottawa and Saguenay Graben. The segment of the Ottawa-Bonnechere Graben west of Ottawa was the first to be recognized as a graben. Since then, it has been traced west to Lake Nipissing, and northwestwards from the confluence of the Mattawa a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canoe
A canoe is a lightweight narrow water vessel, typically pointed at both ends and open on top, propelled by one or more seated or kneeling paddlers facing the direction of travel and using a single-bladed paddle. In British English, the term ''canoe'' can also refer to a kayak, while canoes are called Canadian or open canoes to distinguish them from kayaks. Canoes were developed by cultures all over the world, including some designed for use with sails or outriggers. Until the mid-19th century, the canoe was an important means of transport for exploration and trade, and in some places is still used as such, sometimes with the addition of an outboard motor. Where the canoe played a key role in history, such as the Northern United States, Canada, and New Zealand, it remains an important theme in popular culture. Canoes are now widely used for competition and pleasure, such as racing, whitewater, touring and camping, freestyle and general recreation. Canoeing has been part ...

Fur Trade
The fur trade is a worldwide industry dealing in the acquisition and sale of animal fur. Since the establishment of a world fur market in the early modern period, furs of boreal, polar and cold temperate mammalian animals have been the most valued. Historically the trade stimulated the exploration and colonization of Siberia, northern North America, and the South Shetland and South Sandwich Islands. Today the importance of the fur trade has diminished; it is based on pelts produced at fur farms and regulated fur-bearer trapping, but has become controversial. Animal rights organizations oppose the fur trade, citing that animals are brutally killed and sometimes skinned alive. Fur has been replaced in some clothing by synthetic imitations, for example, as in ruffs on hoods of parkas. Continental fur trade Russian fur trade Before the European colonization of the Americas, Russia was a major supplier of fur pelts to Western Europe and parts of Asia. Its trade developed in ...

Lake Superior
Lake Superior in central North America is the largest freshwater lake in the world by surface areaThe Caspian Sea is the largest lake, but is saline, not freshwater. and the third-largest by volume, holding 10% of the world's surface fresh water. The northern and westernmost of the Great Lakes of North America, it straddles the Canada–United States border with the province of Ontario to the north and east, and the states of Minnesota to the northwest and Wisconsin and Michigan to the south. It drains into Lake Huron via St. Marys River, then through the lower Great Lakes to the St. Lawrence River and the Atlantic Ocean. Name The Ojibwe name for the lake is ''gichi-gami'' (in syllabics: , pronounced ''gitchi-gami'' or ''kitchi-gami'' in different dialects), meaning "great sea".

Étienne Brûlé
Étienne Brûlé (; – c. June 1633) was the first European explorer to journey beyond the St. Lawrence River into what is now known as Canada. He spent much of his early adult life among the Hurons, and mastered their language and learned their culture. Brûlé became an interpreter and guide for Samuel de Champlain, who later sent Brûlé on a number of exploratory missions, among which he is thought to have preceded Champlain to the Great Lakes, reuniting with him upon Champlain's first arrival at Lake Huron. Among his many travels were explorations of Georgian Bay and Lake Huron, as well as the Humber and Ottawa Rivers. Champlain agreed to send Brûlé, at his own request, as an interpreter to live among the Onontchataron, an Algonquin people, in 1610. In 1629, during the Anglo-French War, he escaped after being captured by the Seneca tribe. Brûlé was killed by the Bear tribe of the Huron people, who believed he had betrayed them to the Seneca.

Waterfall
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which Erosion, erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Pothole
A pothole is a depression in a road surface, usually asphalt pavement, where traffic has removed broken pieces of the pavement. It is usually the result of water in the underlying soil structure and traffic passing over the affected area. Water first weakens the underlying soil; traffic then fatigues and breaks the poorly supported asphalt surface in the affected area. Continued traffic action ejects both asphalt and the underlying soil material to create a hole in the pavement. Formation According to the US Army Corps of Engineers's Cold Regions Research and Engineering Laboratory, pothole formation requires two factors to be present at the same time: water and traffic. Water weakens the soil beneath the pavement while traffic applies the loads that stress the pavement past the breaking point. Potholes form progressively from fatigue of the road surface which can lead to a precursor failure pattern known as crocodile (or alligator) cracking. Eventually, chunks of pavement b ...

Ochre
Ochre ( ; , ), or ocher in American English, is a natural clay earth pigment, a mixture of ferric oxide and varying amounts of clay and sand. It ranges in colour from yellow to deep orange or brown. It is also the name of the colours produced by this pigment, especially a light brownish-yellow. A variant of ochre containing a large amount of hematite, or dehydrated iron oxide, has a reddish tint known as "red ochre" (or, in some dialects, ruddle). The word ochre also describes clays coloured with iron oxide derived during the extraction of tin and copper. Earth pigments Ochre is a family of earth pigments, which includes yellow ochre, red ochre, purple ochre, sienna, and umber. The major ingredient of all the ochres is iron(III) oxide-hydroxide, known as limonite, which gives them a yellow colour. * Yellow ochre, , is a hydrated iron hydroxide (limonite) also called gold ochre. * Red ochre, , takes its reddish colour from the mineral hematite, which is an anhydrous iron ...
