RCAF Station Cranberry Portage
Royal Canadian Air Force Station Cranberry Portage (also RCAF Station Cranberry Portage) was a military installation located in Cranberry Portage, Manitoba. Located on Athapapuskow Lake, RCAF Cranberry Portage was one of eight Sector Control Stations (SCS 700) on the Mid-Canada Line system of early warning radar stations. Each SCS received signals from a series of unmanned doppler transmitters located approximately 50 km apart. In Cranberry Portage, radio wave signals were transmitted along the chain of stations to the SCS, then to RCAF Station North Bay by land line. The radar station achieved full strength in April 1957 and was supported by RCAF Station Winnipeg. The Mid-Canada Line operations ceased in January 1964 and RCAF Station Cranberry Portage was turned over by the Department of National Defence (Canada), Department of National Defence to the Government of Manitoba for civilian use. Civilian use The residential and other facilities were used by the Frontier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mid-Canada Line
The Mid-Canada Line (MCL), also known as the McGill Fence, was a line of radar stations running east–west across the middle of Canada, used to provide early warning of a Soviet bomber attack on North America. It was built to supplement the Pinetree Line, which was located farther south. The majority of Mid-Canada Line stations were used only briefly from the late 1950s to the mid-1960s, as the attack threat changed from bombers to ICBMs. As the MCL was closed down, the early warning role passed almost entirely to the newer and more capable DEW Line farther north. The MCL was based on the bistatic radar principle, using separated transmitters and receivers. An aircraft flying anywhere between the stations would reflect some of the transmitted signal towards the receiver, where it would mix with the signal travelling directly from the transmitter. The mixing of the two signals produces a pattern that is very easy to detect using simple electronics. As the transmitter is not pul ...

Cranberry Portage, Manitoba
Cranberry Portage is an unincorporated community recognized as a local urban district located in the Rural Municipality of Kelsey, Manitoba. It was an important part of the pre-European contact trade routes of the Cree and Assiniboine peoples. Long before the fur trade with the Bay and during the Fur Trade, this location was used as a campsite and portage between Grassy River, at the head of a number of well-used routes from Hudson Bay, and Lake Athapapuskow, which connected to the Saskatchewan River system. Once on the Saskatchewan routes were open through the prairies to the foothills of the Rocky Mountains. History The area has been inhabited since prehistoric times. Archaeological digs on Lake Athapapuskow revealed pottery, arrowheads, and other artifacts which were at least 2,500 years old and indicated regular habitation by the "Shield Archaic Culture", who hunted caribou in the area as far back as 7000 years ago. They were eventually supplanted by the Woodland Cree who we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Frontier School Division
Frontier School Division is the largest geographical school division in Manitoba, Canada, covering most schools in northern Manitoba. With 41 schools operating across Manitoba, the Frontier School Division provides educational services to a larger geographical area than any other school division in Canada. A unique organization, the Frontier School Division operates schools in small Manitoba communities that are often only accessible by boat, air (float plane), rail, or winter ice road. The widespread geography has necessitated that this single school division be sub-divided into five "areas", with the main division office located in Winnipeg, Manitoba. Located at the Frontier Collegiate Institute campus is the Frontier Collegiate Residence, where high school students from around Area Four and isolated communities that do not have student populations to warrant the operation of a high school program are housed in dormitories so that they may complete their secondary schooling. ...

Frontier Collegiate Institute
A frontier is the political and geographical area near or beyond a boundary. A frontier can also be referred to as a "front". The term came from French in the 15th century, with the meaning "borderland"—the region of a country that fronts on another country (see also marches). Unlike a border—a rigid and clear-cut form of state boundary—in the most general sense a frontier can be fuzzy or diffuse. For example, the frontier between the Eastern United States and the Old West in the 1800s was an area where European American settlements gradually thinned out and gave way to Native American settlements or uninhabited land. The frontier was not always a single continuous area, as California and various large cities were populated before the land that connected those to the East. Frontiers and borders also imply different geopolitical strategies. In Ancient Rome, the Roman Republic experienced a period of active expansion and creating new frontiers. From the reign of Augus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Defence Radar Stations
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention ( greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
