Ausable River (Lake Huron)
The Ausable River is a river in southwestern Ontario Canada which empties into Lake Huron at Port Franks, Ontario. The Ausable's initial source is in a moraine near the community of Staffa, Ontario located in the municipality of West Perth, Ontario at a point above sea level. Although the river has a total measured length of over , because of its meandering course, the mouth in actuality is only from its source near Staffa. The Ausable drains of land, and falls in elevation from source to outlet. In 1875, engineers of the Canada Company engaged in a large scale drainage project, referred to locally as "The Cut", which altered the course of the river dramatically and permitted the draining of several local small lakes and wetlands for agricultural purposes. Before that time the Ausable passed through the village of Grand Bend, where it made an abrupt curve toward the south, paralleling the Lake Huron shoreline for several kilometers, before entering the lake at Port Franks. ...

Provinces And Territories Of Canada
Within the geographical areas of Canada, the ten provinces and three territories are sub-national administrative divisions under the jurisdiction of the Constitution of Canada, Canadian Constitution. In the 1867 Canadian Confederation, three provinces of British North America—New Brunswick, Nova Scotia, and the Province of Canada (which upon Confederation was divided into Ontario and Quebec)—united to form a federation, becoming a fully independent country over the next century. Over its history, Canada's international borders have changed several times as it has added territories and provinces, making it the List of countries and dependencies by area, world's second-largest country by area. The major difference between a Canadian province and a territory is that provinces receive their power and authority from the ''Constitution Act, 1867'' (formerly called the ''British North America Acts, British North America Act, 1867''), whereas territorial governments are creatures of ...

Moraine
A moraine is any accumulation of unconsolidated debris ( regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines ( till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Pr ...

Hydroelectric
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominat ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure t ...

Arkona, Ontario
Arkona is a community located in the municipality of Lambton Shores in southwestern Ontario near the Lambton–Middlesex county line, situated beside the Ausable River, on Former Kings Highway 79 (now Lambton County Road 79), Arkona is roughly halfway between Thedford, and Watford. History Prehistory The site of the village is at the base of the Wyoming Moraine which formed along the shores of ancient Lake Arkona during the retreat of the Wisconsin Glacier some 16,000 years ago. Rich deposits of fossils are revealed at nearby Hungry Hollow. Evidence of early human habitation exists at the site of Paleo hunting camps which were found just a kilometre south of Arkona dating back some 11,000 years. Subsequent migrations of Archaic and Woodland peoples moved into the area as the climate and vegetation changed. Evidence of this long-standing habitation is frequently discovered in the fields surrounding the current village. Arrival of European settlers The first known p ...

Canyon
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examples of mountain-type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiny Softshell Turtle
The spiny softshell turtle (''Apalone spinifera'') is a species of softshell turtle, one of the largest freshwater turtle species in North America. Both the common name, spiny softshell, and the specific name, ''spinifera'' (spine-bearing), refer to the spiny, cone-like projections on the leading edge of the carapace, which are not scutes (scales). Description The spiny softshell turtle's scientific name is very descriptive of the animal. ''Apalone'' comes from the Greek word ''apalos'', meaning soft or tender, and ''spinifera'' is of Latin origin; ''spina-'' referring to thorn or spine and ''-ifer'' meaning bearing. This species is a member of the family Trionychidae, and one of the most distinguishing features of members in this family is the presence of a leathery, moderately flexible carapace. This is caused by loss of keratinized scutes and some bony tissue loss. Spiny softshell turtles have webbed feet, each with three claws. Another distinguishing feature of softshell tur ...

Mussel
Mussel () is the common name used for members of several families of bivalve molluscs, from saltwater and freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval. The word "mussel" is frequently used to mean the bivalves of the marine family Mytilidae, most of which live on exposed shores in the intertidal zone, attached by means of their strong byssal threads ("beard") to a firm substrate. A few species (in the genus '' Bathymodiolus'') have colonised hydrothermal vents associated with deep ocean ridges. In most marine mussels the shell is longer than it is wide, being wedge-shaped or asymmetrical. The external colour of the shell is often dark blue, blackish, or brown, while the interior is silvery and somewhat nacreous. The common name "mussel" is also used for many freshwater bivalves, including the freshwater pearl mussels. Freshwater mussel specie ...

Old Ausable Channel
The Old Ausable Channel is a self-contained waterway in Lambton County, Ontario, Canada that runs through the Pinery Provincial Park and the community of Grand Bend. It is a 14 kilometre long river channel that was isolated from the Ausable River by the digging of canals for drainage in the late nineteenth century. Part of the Pinery Provincial Park's rare oak savanna, the channel is an important part of the region's ecosystem. History The Ausable River source is a moraine near Staffa, Ontario and it empties into Lake Huron at Port Franks. Starting in the 1870s, the Canada Company engaged in large-scale drainage projects within its watershed and adjacent lakes to prepare the land for vegetable agriculture. In 1875-1876, a drainage canal called "The Cut" was dug, draining the Thedford Marsh and Lake Burwell, diverting the course of the Ausable. In 1892, a second 400 yard trench was created to outlet Parkhill Creek (a tributary of the Ausable) into Lake Huron at Grand Bend, O ...

Pinery Provincial Park
Pinery Provincial Park is a provincial park located on Lake Huron near Grand Bend, Ontario. It occupies an area of 25.32 square kilometres (6,330 acres). It is a natural environment-class Provincial Park created to help preserve oak savannah and the beach dune ecology. It has 1,275 sites of which 404 have electrical hookups. These include the yurt camping area and the group camping sites. The initial package of land for the park was purchased from the Canada Company in 1957. In 1966, the park saw a 433-acre addition, adding 200 campsites to the park's existing 1,075 to accommodate the growth of the park patronage, which had reached peaks of 1,500 campers per day, causing many to be packed into overflow areas. Visitors to Pinery Provincial Park may access free wireless internet at the Visitor Centre provided by the Friends of Pinery Park.

Grand Bend, Ontario
Grand Bend is a community located on the shores of Lake Huron in Southwestern Ontario, Canada. It is part of the Municipality of Lambton Shores in Lambton County. History Grand Bend is situated on the traditional territory of the Attawandaron and Ojibwe/Chippewa First Nations. It was ceded to the crown as part of a parcel called the Huron Tract, in Treaty 27, 1829. In the 1830s a group of English and Scottish settlers bought lots from the Canada Company, a land development firm. One of the original settlers, Benjamin Brewster gave his name to the village after he and his business partner David Smart secured rights to dam the Ausable River and started a sawmill in 1832. The villagers were mainly the families of the millhands and fishermen. Their homesteads were situated on the south side of the present village, but Grand Bend was originally founded and discovered by Frank Salter, who was a very well-known Lake resort owner and country club developer. For twenty years Brewster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
