Lake Peace
Lake Peace was a post ice-age glacial lake in what is now the Peace River basin in northeastern British Columbia and northwestern Alberta. It formed approximately 14,000 BCE, after the Last Glacial Maximum, as the Laurentide Ice Sheet and Cordilleran Ice Sheet began to melt and retreat, and may have played an important role as an easily navigatable section of an inland human migration route from Asia to the Americas. It remains unclear how long the lake lasted, or if it was drained in a glacial lake outburst flood, similar to the Missoula Floods that occurred on the southern margins of these same ice sheets.

Peace River
The Peace River (french: links=no, rivière de la Paix) is a river in Canada that originates in the Rocky Mountains of northern British Columbia and flows to the northeast through northern Alberta. The Peace River joins the Athabasca River in the Peace-Athabasca Delta to form the Slave River, a tributary of the Mackenzie River. The Finlay River, the main headwater of the Peace River, is regarded as the ultimate source of the Mackenzie River. The combined Finlay–Peace–Slave–Mackenzie river system is the 13th longest river system in the world. History The regions along the river are the traditional home of the Danezaa people, called the Beaver by the Europeans. The fur trader Peter Pond is believed to have visited the river in 1785. In 1788 Charles Boyer of the North West Company established a fur trading post at the river's junction with the Boyer River. In 1792 and 1793, the explorer Alexander Mackenzie travelled up the river to the Continental Divide. Mackenzie r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geology Of British Columbia
The geology of British Columbia is a function of its location on the leading edge of the North American continent. The mountainous physiography and the diversity of rock types and ages hint at the complex geology, which is still undergoing revision despite a century of exploration and mapping. The country's most prominent geological features are mountain ranges, including the North American Cordillera, which stretches from Southern Mexico to Alaska. Terrane theory Terrane theory was first proposed by Jim Monger of the Geological Survey of Canada and Charlie Rouse in 1971 as an explanation for a set of fusulinid fossils found in central British Columbia. Rather than use facies changes or seaways (which were common explanations at the time), the two geologists proposed that the fossils in question had been part of an assemblage of rocks that had migrated across the Pacific Ocean to their present location. This theory was then developed by Porter Irwin and Davy Jones of the US ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lakes Of Alberta
This is a list of lakes in Alberta, Canada. Most of Alberta's lakes were formed during the last glaciation, about 12,000 years ago. There are many different types of lakes in Alberta, from glacial lakes in the Canadian Rockies to small shallow lakes in the prairies, brown water lakes in the northern boreal forest and muskeg, kettle holes and large lakes with sandy beaches and clear water in the central plains. Distribution of the lakes throughout the province of Alberta is irregular, with many water bodies in the wet boreal plains in the north, and very few in the semi-arid Palliser's Triangle in the southeast. __TOC__ River basins Most of Alberta's waters are drained in a general north or northeastern direction, with six major rivers forming four major watersheds collecting the water and removing it from the province: [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lakes Of British Columbia
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peace River Country
The Peace River Country (or Peace Country; french: Région de la Rivière-de-la-paix) is an aspen parkland region centring on the Peace River in Canada. It extends from northwestern Alberta to the Rocky Mountains in northeastern British Columbia, where a certain portion of the region is also referred to as the Peace River Block. Geography The Peace River Country includes the incorporated communities of Fort St. John, Dawson Creek, Tumbler Ridge and Chetwynd in British Columbia. Major communities in the Alberta portion of the Peace Country include Grande Prairie, Peace River, High Level and Fairview.

Peace River Regional District
The Peace River Regional District is a regional district in northeastern British Columbia, Canada. The regional district comprises seven municipalities and four electoral areas. Its member municipalities are the cities of Fort St. John and Dawson Creek, the district municipalities of Tumbler Ridge, Chetwynd, Taylor, and Hudson's Hope, and the village of Pouce Coupe. The district's administrative offices are in Dawson Creek. The regional district also has four regional district electoral areas: B, C, D and E. Six Indian reserves and one Indian settlement are located within the regional district's boundaries, but are not governed by the regional district. Its modern boundaries were established on October 31, 1987, when the Peace River-Liard Regional District was divided in two. The separated northern territories became the Fort Nelson-Liard Regional District, now the Northern Rockies Regional Municipality. Located east of the Rockies, the regional district is characterize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Lakes Of Canada
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period wi ...

Missoula Floods
The Missoula floods (also known as the Spokane floods or the Bretz floods or Bretz's floods) were cataclysmic glacial lake outburst floods that swept periodically across eastern Washington and down the Columbia River Gorge at the end of the last ice age. These floods were the result of periodic sudden ruptures of the ice dam on the Clark Fork River that created Glacial Lake Missoula. After each ice dam rupture, the waters of the lake would rush down the Clark Fork and the Columbia River, flooding much of eastern Washington and the Willamette Valley in western Oregon. After the lake drained, the ice would reform, creating Glacial Lake Missoula again. These floods have been researched since the 1920s. During the last deglaciation that followed the end of the Last Glacial Maximum, geologists estimate that a cycle of flooding and reformation of the lake lasted an average of 55 years and that the floods occurred several times over the 2,000-year period between 15,000 and 13,000 year ...

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
