Jasper Palisade
The Jasper Palisade is a geologic formation of Jasper National Park, Alberta, Canada. It is so named because it has a sheer cliff face and vertical markings, reminiscent of palisade walls used as a protective enclosure around forts. The Palisade can be seen along Alberta Highway 16 (the Yellowhead Highway) in the west as the highway first crosses the Athabasca River approximately east of Jasper townsite. The Palisade was once home to a forest fire lookout A fire lookout (partly also called a fire watcher) is a person assigned the duty to look for fire from atop a building known as a fire lookout tower. These towers are used in remote areas, normally on mountain tops with high elevation and a ... station, as it afforded a clear view of much of the Athabasca River Valley. The fire lookout has since been abandoned as more modern techniques of fire detection have become available. However, the clear view of the Athabasca River Valley remains, and one can hike to the crest o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geologic Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob We ...

Jasper National Park
Jasper National Park is a national park in Alberta, Canada. It is the largest national park within Alberta's Rocky Mountains spanning . It was established as a national park in 1930 and declared a UNESCO World Heritage Site in 1984. Its location is north of Banff National Park and west of Edmonton. The park contains the glaciers of the Columbia Icefield, springs, lakes, waterfalls and mountains. History First Nations The territory encompassed by what is now Jasper National Park has been inhabited since time immemorial by Nakoda, Cree, Secwépemc, and Dane-zaa peoples. Plainview projectile points have been found at the head of Jasper Lake, dating back to between 8000 and 7000 BCE. In the centuries between then and the establishment of the park, First Nations land use has fluctuated according to climatic variations over the long term, and according to cyclical patterns of ungulate population numbers, particularly elk, moose, mule deer, and occasionally caribou.

Alberta
Alberta ( ) is one of the thirteen provinces and territories of Canada. It is part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to the west, Saskatchewan to the east, the Northwest Territories (NWT) to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada (Saskatchewan being the other). The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds. Alberta is the fourth largest province by area at , and the fourth most populous, being home to 4,262,635 people. Alberta's capital is Edmonton, while Calgary is its largest city. The two are Alberta's largest census metropolitan areas. More tha ... [...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 ...

Palisade
A palisade, sometimes called a stakewall or a paling, is typically a fence or defensive wall made from iron or wooden stakes, or tree trunks, and used as a defensive structure or enclosure. Palisades can form a stockade. Etymology ''Palisade'' derives from ''pale'', from the Latin word ', meaning stake, specifically when used side by side to create a wood defensive wall. Typical construction Typical construction consisted of small or mid-sized tree trunks aligned vertically, with as little free space in between as possible. The trunks were sharpened or pointed at the top, and were driven into the ground and sometimes reinforced with additional construction. The height of a palisade ranged from around a metre to as high as 3–4 m. As a defensive structure, palisades were often used in conjunction with earthworks. Palisades were an excellent option for small forts or other hastily constructed fortifications. Since they were made of wood, they could often be quickly and easi ...

Fort
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acte ...

Alberta Highway 16
Alberta Provincial Highway No. 16, commonly referred to as Highway 16, is a major east–west highway in central Alberta, Canada, connecting Jasper to Lloydminster via Edmonton. It forms a portion of the Yellowhead Highway, a major interprovincial route of the Trans-Canada Highway system that stretches from Masset, British Columbia, to Portage la Prairie, Manitoba, near Winnipeg. Highway 16 spans approximately from Alberta's border with British Columbia in the west to its border with Saskatchewan in the east. As of 2010, all but less than of the route was divided, with a minimum of two lanes in each direction. It is designated a core route in Canada's National Highway System. Route description Jasper National Park British Columbia Highway 16 becomes Alberta Highway 16 as it crosses the Continental Divide and Yellowhead Pass into Alberta, entering Jasper National Park. It travels in an easterly direction through the Municipality of Jasper unt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellowhead Highway
The Yellowhead Highway (french: Route Yellowhead) is a major interprovincial highway in Western Canada that runs from Winnipeg to Graham Island off the coast of British Columbia via Saskatoon and Edmonton. It stretches across the four western Canadian provinces of British Columbia, Alberta, Saskatchewan, and Manitoba and is part of the Trans-Canada Highway system and the larger National Highway System, but should not be confused with the more southerly, originally-designated Trans-Canada Highway. The highway was officially opened in 1970. Beginning in 1990, the green and white Trans-Canada logo was used to designate the roadway. The highway is named for the Yellowhead Pass, the route chosen to cross the Canadian Rockies. The pass and the highway are named after a fur trader and explorer named Pierre Bostonais. He had yellow streaks in his hair, and was nicknamed "Tête Jaune" (Yellowhead). Almost the entire length of the highway is numbered as 16, except for the section in ...

Athabasca River
The Athabasca River (French: ''Rivière Athabasca'') is a river in Alberta, Canada, which originates at the Columbia Icefield in Jasper National Park and flows more than before emptying into Lake Athabasca. Much of the land along its banks is protected in national and provincial parks, and the river is designated a Canadian Heritage River for its historical and cultural importance. The scenic Athabasca Falls is located about upstream from Jasper. Etymology The name ''Athabasca'' comes from the Woods Cree word , which means "herethere are plants one after another", likely a reference to the spotty vegetation along the river. Course The Athabasca River originates in Jasper National Park, in an unnamed lake at the toe of the Columbia Glacier within the Columbia Icefield, between Mount Columbia, Snow Dome, and the Winston Churchill Range, at an elevation of approximately . It travels before draining into the Peace-Athabasca Delta near Lake Athabasca south of Fort Chipew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jasper, Alberta
Jasper is a specialized municipality and townsite in western Alberta within the Canadian Rockies. The townsite is in the Athabasca River valley and is the commercial centre of Jasper National Park. History Established in 1813, Jasper House was first a fur trade outpost of the North West Company, and later Hudson's Bay Company, on the York Factory Express trade route to what was then called "New Caledonia" (now British Columbia) and Fort Vancouver on the lower Columbia River. Jasper House was 35 km north of today's town of Jasper. Jasper Forest Park was established in 1907. The railway siding at the location of the future townsite was established by the Grand Trunk Pacific Railway in 1911 and originally named Fitzhugh after a Grand Trunk vice president (along the Grand Trunk's "alphabet" line). The Canadian Northern Railway began service to its ''Jasper Park'' station in 1912, about 700 m from GTP's Fitzhugh station. The townsite was surveyed in 1913 by H. ...

Fire Lookout
A fire lookout (partly also called a fire watcher) is a person assigned the duty to look for fire from atop a building known as a fire lookout tower. These towers are used in remote areas, normally on mountain tops with high elevation and a good view of the surrounding terrain, to spot smoke caused by a wildfire. Once a possible fire is spotted, "Smoke Reports", or "Lookout Shots" are relayed to the local Emergency Communications Center (ECC), often by radio or phone. A fire lookout can use a device known as an Osborne Fire Finder to obtain the radial in degrees off the tower, and the estimated distance from the tower to the fire. Part of the lookout's duties include taking weather readings and reporting the findings to the Emergency Communications Center throughout the day. Often several lookouts will overlap in coverage areas and each will “cross” the same smoke, allowing the ECC to use triangulation from the radials to achieve an accurate location of the fire. On ...
