Lake Stanley
Lake Stanley, also called the ''Stanley unconformity'', is a postglacial freshwater lake that occupied part of what is now the basin of Lake Huron during a hydrologically significant period from 10,000 years Before Present (B.P.). The lake’s surface level was approximately 70 meters below the current lake’s water surface. The lake, although geographically smaller than the current Lake Huron, was fed from a large Lake Chippewa watershed that included the basin of what is now Lake Michigan. During this period, the water from Lake Stanley drained through an outlet or outlets adjacent to what is now North Bay, Ontario North Bay is a city in Northeastern Ontario, Canada. It is the seat of Nipissing District, and takes its name from its position on the shore of Lake Nipissing. North Bay developed as a railroad centre, and its airport was an important military ....

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Great Lakes
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the mid-east region of North America that connect to the Atlantic Ocean via the Saint Lawrence River. There are five lakes, which are Superior, Michigan, Huron, Erie, and Ontario and are in general on or near the Canada–United States border. Hydrologically, lakes Michigan and Huron are a single body joined at the Straits of Mackinac. The Great Lakes Waterway enables modern travel and shipping by water among the lakes. The Great Lakes are the largest group of freshwater lakes on Earth by total area and are second-largest by total volume, containing 21% of the world's surface fresh water by volume. The total surface is , and the total volume (measured at the low water datum) is , slightly less than the volume of Lake Baikal (, 22–23% of the world's surface fresh water). Because of their sea-like characteristics, such as rolling waves, sustained wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Chippewa
Lake Chippewa was a prehistoric proglacial lake. The basin is now Lake Michigan. It formed about 10,600 years before present (YBP). The lake occupied the depression left by the Michigan Lobe of the Laurentide Ice Sheet.University of Wisconsin, Green Bay, Dept of Geology Origin The lake formed from glacial Lake Algonquin as water levels dropped, occupying only the deepest parts of the Lake Michigan basin. The waters drained through the Straits of Mackinac, then across Lake Stanley into either Lake Hough and then to the St. Lawrence River by way of the Ottawa River valley, or through the St. Clair and Detroit rivers to an Early Lake Erie and out the Niagara River towards the St. Lawrence. Around 10,300 YBP, Lake Chippewa’s levels continued to drop, and the basin was a self-contained body of water without an outlet. Levels returned and Lake Chippewa again flowed through the canyon at Mackinac until around 7,500 YBP. At that time, the Nipissing Great Lakes mer ...

French River (Ontario)
The French River (french: Rivière des Français, oj, Wemitigoj-Sibi) is a river in Central Ontario, Canada. It flows from Lake Nipissing west to Georgian Bay. The river largely follows the boundary between the Parry Sound District and the Sudbury District, and in most contexts is considered the dividing line between Northern and Southern Ontario. The French River was designated a Canadian Heritage River in 1986. Geography The French River flows through typical Canadian Shield country, in many places exposing rugged glaciated rock but also through heavily forested areas on the upper portion. The mouth of the river contains countless islands and numerous channels which vary from narrow, enclosed steep-walled gorges, falls and rapids, to broad expanses of open water. Tributaries of this river include the: *Wanapitei River *Pillow River * Murdock River *Wolseley River *Little French River * Pickerel River * Restoule River * Hall River History It was used as a transportation ...

Lake Huron
Lake Huron ( ) is one of the five Great Lakes of North America. Hydrologically, it comprises the easterly portion of Lake Michigan–Huron, having the same surface elevation as Lake Michigan, to which it is connected by the , Straits of Mackinac. It is shared on the north and east by the Canadian province of Ontario and on the south and west by the U.S. state of Michigan. The name of the lake is derived from early French explorers who named it for the Huron people inhabiting the region. The Huronian glaciation was named from evidence collected from Lake Huron region. The northern parts of the lake include the North Channel and Georgian Bay. Saginaw Bay is located in the southwest corner of the lake. The main inlet is the St. Marys River, and the main outlet is the St. Clair River. Geography By surface area, Lake Huron is the second-largest of the Great Lakes, with a surface area of —of which lies in Michigan; and lies in Ontario—making it the third-largest fre ...

North Bay, Ontario
North Bay is a city in Northeastern Ontario, Canada. It is the seat of Nipissing District, and takes its name from its position on the shore of Lake Nipissing. North Bay developed as a railroad centre, and its airport was an important military location during the Cold War. History The site of North Bay is part of a historic canoe route where Samuel de Champlain took a party up the Ottawa River, through present-day Mattawa, on to Trout Lake and via the La Vase Creek to Lake Nipissing. Apart from Indigenous people, voyageurs and surveyors, there was little activity in the Lake Nipissing area until the arrival of the Canadian Pacific Railway (CPR) in 1882. That was the point where the Canada Central Railway (CCR) extension ended. The CCR was owned by Duncan McIntyre who amalgamated it with the CPR and became one of the handful of officers of the newly formed CPR. The CCR started in Brockville and extended to Pembroke. It then followed a westward route along the Ottawa River ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Former Lakes Of The United States
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the a ...
