Cariboo Plateau
The Cariboo Plateau is a volcanic plateau in south-central British Columbia, Canada. It is part of the Fraser Plateau that itself is a northward extension of the North American Plateau. The southern limit of the plateau is the Bonaparte River although some definitions include the Bonaparte Plateau between that river and the Thompson, but it properly is a subdivision of the Thompson Plateau. The portion of the Fraser Plateau west of the Fraser River is properly known as the Chilcotin Plateau but is often mistakenly considered to be part of the Cariboo Plateau, which is east of the Fraser. As a region and historical identity, the Cariboo is sometimes considered to extend to the Thompson River to the south of that, and to border on the city of Kamloops at its southeastern corner and even as far as Lytton, at the confluence of the Fraser and Thompson Rivers. The town of Lillooet is generally considered to be in the Cariboo, while the Bridge River Country to its west was sometimes ref ...

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] |
Cariboo Gold Rush
The Cariboo Gold Rush was a gold rush in the Colony of British Columbia, which later joined the Canadian province of British Columbia. The first gold discovery was made at Hills Bar in 1858, followed by more strikes in 1859 on the Horsefly River, and on Keithley Creek and Antler Creek in 1860. The actual rush did not begin until 1861, when these discoveries were widely publicized. By 1865, following the strikes along Williams Creek, the rush was in full swing. Towns grew up, the most famous of these being Barkerville, now preserved as a heritage site and tourist attraction. Other important towns of the Cariboo gold rush era were Keithley Creek, Quesnel Forks or simply "the Forks", Antler, Richfield, Quesnellemouthe (which would later be shortened to Quesnel), Horsefly and, around the site of the Hudson's Bay Company's fort of the same name, Alexandria. Williams Creek Richfield Richfield was the first strike on Williams Creek, and became the seat of government in the regio ...

Coast Mountains
The Coast Mountains (french: La chaîne Côtière) are a major mountain range in the Pacific Coast Ranges of western North America, extending from southwestern Yukon through the Alaska Panhandle and virtually all of the Coast of British Columbia south to the Fraser River. The mountain range's name derives from its proximity to the sea coast, and it is often referred to as the Coast Range. The range includes volcanic and non-volcanic mountains and the extensive ice fields of the Pacific and Boundary Ranges, and the northern end of the volcanic system known as the Cascade Volcanoes. The Coast Mountains are part of a larger mountain system called the Pacific Coast Ranges or the Pacific Mountain System, which includes the Cascade Range, the Insular Mountains, the Olympic Mountains, the Oregon Coast Range, the California Coast Ranges, the Saint Elias Mountains and the Chugach Mountains. The Coast Mountains are also part of the American Cordilleraa Spanish term for an extensive chain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garibaldi Volcanic Belt
The Garibaldi Volcanic Belt is a northwest–southeast trending volcanic chain in the Pacific Ranges of the Coast Mountains that extends from Watts Point in the south to the Ha-Iltzuk Icefield in the north. This chain of volcanoes is located in southwestern British Columbia, Canada. It forms the northernmost segment of the Cascade Volcanic Arc, which includes Mount St. Helens and Mount Baker. Most volcanoes of the Garibaldi chain are dormant stratovolcanoes and subglacial volcanoes that have been eroded by glacial ice. Less common volcanic landforms include cinder cones, volcanic plugs, lava domes and calderas. These diverse formations were created by different styles of volcanic activity, including Peléan and Plinian eruptions. Eruptions along the length of the chain have created at least three major volcanic zones. The first began in the Powder Mountain Icefield 4.0 million years ago. Mount Cayley began its formation during this period. Multiple eruptions from 2.2& ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Rock
Volcanic rock (often shortened to volcanics in scientific contexts) is a rock formed from lava erupted from a volcano. In other words, it differs from other igneous rock by being of volcanic origin. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these reasons, in geology, volcanics and shallow hypabyssal rocks are not always treated as distinct. In the context of Precambrian shield geology, the term "volcanic" is often applied to what are strictly metavolcanic rocks. Volcanic rocks and sediment that form from magma erupted into the air are called "volcaniclastics," and these are technically sedimentary rocks. Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate boundaries and in flood basalt provinces. It has been estimated t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chilcotin Group
The Chilcotin Group, also called the Chilcotin Plateau Basalts, is a large area of basaltic lava that forms a volcanic plateau running parallel with the Garibaldi Volcanic Belt in south-central British Columbia, Canada. Predominantly, during Miocene and Pliocene times, a medium-sized volcanic field of overlapping vents occurred in British Columbia's Interior Plateau. The distribution is assumed to engulf up to 50,000 km2 of the Pacific Northwest, forming a medium-sized large igneous province, of volume 3300 km3. Retrieved on 2012-09-22 Volcanism occurred as late as Oligocene time, but continues sporadically up to present. Eruptions were most vigorous 6- ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flood Basalt
A flood basalt (or plateau basalt) is the result of a giant volcanic eruption or series of eruptions that covers large stretches of land or the ocean floor with basalt lava. Many flood basalts have been attributed to the onset of a hotspot reaching the surface of the earth via a mantle plume. Flood basalt provinces such as the Deccan Traps of India are often called '' traps'', after the Swedish word ''trappa'' (meaning "staircase"), due to the characteristic stairstep geomorphology of many associated landscapes. Michael R. Rampino and Richard Stothers (1988) cited eleven distinct flood basalt episodes occurring in the past 250 million years, creating large igneous provinces, lava plateaus, and mountain ranges. However, more have been recognized such as the large Ontong Java Plateau, and the Chilcotin Group, though the latter may be linked to the Columbia River Basalt Group. Large igneous provinces have been connected to five mass extinction events, and may be associated with b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fraser River
The Fraser River is the longest river within British Columbia, Canada, rising at Fraser Pass near Blackrock Mountain in the Rocky Mountains and flowing for , into the Strait of Georgia just south of the City of Vancouver. The river's annual discharge at its mouth is or , and it discharges 20 million tons of sediment into the ocean. Naming The river is named after Simon Fraser, who led an expedition in 1808 on behalf of the North West Company from the site of present-day Prince George almost to the mouth of the river. The river's name in the Halqemeylem (Upriver Halkomelem) language is , often seen archaically as Staulo, and has been adopted by the Halkomelem-speaking peoples of the Lower Mainland as their collective name, . The river's name in the Dakelh language is . The ''Tsilhqot'in'' name for the river, not dissimilar to the ''Dakelh'' name, is , meaning Sturgeon ''()'' River ''()''. Course The Fraser drains a area.

100 Mile House
100 Mile House is a district municipality located in the South Cariboo region of central British Columbia, Canada. History 100 Mile House was originally known as Bridge Creek House, named after the creek running through the area. Its origins as a settlement go back to the time when Thomas Miller owned a collection of ramshackle buildings serving the traffic of the gold rush as a resting point for travellers moving between Kamloops and Fort Alexandria, which was north of 100 Mile House farther along the Hudson's Bay Brigade Trail. It acquired its current name during the Cariboo Gold Rush where a roadhouse was constructed in 1862 at the mark up the Old Cariboo Road from Lillooet. In 1930, Lord Martin Cecil left England to come to 100 Mile House and manage the estate owned by his father, the 5th Marquess of Exeter. The estate's train stop on the Pacific Great Eastern (now BC Rail leased and operated by Canadian National) railway is to the west of town and called Exeter. Th ...
