Flourmill Volcanoes
The Flourmill Volcanoes, also known as The Flourmills, are a small volcano range near the west boundary of Wells Gray Provincial Park in east-central British Columbia, Canada. Located north of Mahood Lake and west of the Clearwater River, they form part of the Wells Gray-Clearwater volcanic field. Geography Two volcanic centres form the range, namely ''Flourmill Centre'' and ''Spanish Lake Centre''. During volcanic activity 3,000 years ago, the craters of two cinder cones were breached, and lava flowed out the south side into the pass between Spanish Creek and Flourmill Creek. The lava then dammed Spanish Creek, creating Spanish Lake, occupying about of the Spanish valley to the southwest. This lava flow averages thick.Neave, Roland (2015). ''Exploring Wells Gray Park'', 6th edition. Wells Gray Tours, Kamloops, BC. . Both cones were built upon unweathered glacial material. Spanish Lake Centre Situated east of Spanish Lake is the northerly Spanish Lake Centre with an elevation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cariboo Land District
The Cariboo Land District is a cadastral survey subdivision of the province of British Columbia, Canada, created with rest of those on Mainland British Columbia via the Lands Act of the Colony of British Columbia in 1860. The British Columbia government's BC Names system, a subdivision of GeoBC, defines a land district as "a territorial division with legally defined boundaries for administrative purposes" All land titles and surveys use the Land District system as the primary point of reference, and entries in BC Names for placenames and geographical objects are so listed. Description The Cariboo Land District is one of the original Land Districts of the province, its northern portion having been split off as the Peace River Land District, which is to its north. To is south is the Lillooet Land District and a small northerly extension of the Kamloops Subdivision Yale Land District. On its west are Ranges 3, 4 and 5 of the Coast Land District and part of the southeastern flank of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Block
A volcanic block is a fragment of rock that measures more than in diameter and is erupted in a solid condition. Blocks are formed from material from previous eruptions or from country rock and are therefore mostly accessory or accidental in origin. Blocks also occur due to the impact and breakage of volcanic bombs (a bomb is a block with streamlined appearance, often expelled in a molten state). Bombs can also occur due to the disruption of the crust of a lava dome that has formed up or over a vent during an eruption. Features Blocks are nearly always angular to sub-angular and roughly equidimensional. If the parent rock is flow-foliated lava, sedimentary material or schistose metamorphic rocks, the blocks may have a plate-like or slab-like form. In other cases, blocks derived from great depths may resemble polished water-worn pebbles and are cobbled due to fluidisation and upwards transport. Blocks can be enormous and may be transported great distances from the volcanic vent. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rathtrevor Beach Provincial Park
Rathtrevor Beach Provincial Park is a provincial park in Parksville, British Columbia, Canada. Located at the east end of the town, the 347-hectare park features a two-kilometre long stretch of sandy beach, a stand of old-growth Douglas fir trees and 174 vehicle-accessible and 25 walk-in camping spaces. Popular year-round, the park is easily accessible from Highway 19. The sandy beach is the main attraction. At low tide, it stretches nearly a kilometre out into the Strait of Georgia. Wildlife The park is an important stopover area for migratory birds, notably brant geese, which use the beach as a staging area from March 1 to April 15. Deer, raccoons, minks and squirrels have been seen occupying the park during spring migrations. Furthermore, aquatic animals such as otters use the park. Origin of the name Rathtrevor takes its name from the Rath family who homesteaded on the land in the late 19th century. The family eventually established a private campground on the site, adding ...

Vancouver Island
Vancouver Island is an island in the northeastern Pacific Ocean and part of the Canadian Provinces and territories of Canada, province of British Columbia. The island is in length, in width at its widest point, and in total area, while are of land. The island is the largest by area and the most populous along the west coasts of the Americas. The southern part of Vancouver Island and some of the nearby Gulf Islands are the only parts of British Columbia or Western Canada to lie south of the 49th parallel north, 49th parallel. This area has one of the warmest climates in Canada, and since the mid-1990s has been mild enough in a few areas to grow Mediterranean Sea, Mediterranean crops such as olives and lemons. The population of Vancouver Island was 864,864 as of 2021. Nearly half of that population (~400,000) live in the metropolitan area of Greater Victoria, the capital city of British Columbia. Other notable cities and towns on Vancouver Island include Nanaimo, Port Alberni, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Hunter (Canadian Politician)
Joseph Hunter (May 7, 1839 – April 8, 1935) was a Scottish-born surveyor, civil engineer and political figure in British Columbia. He represented Cariboo from 1871 to 1875 and from 1900 to 1904 and Comox from 1890 to 1898 in the Legislative Assembly of British Columbia. He was born in Aberdeen in 1839 and educated there, concluding his studies at the University of Aberdeen. Hunter came to Victoria, British Columbia in 1864. From 1872, he worked performing surveys for the Canadian Pacific Railway. In 1875, he was employed by the Canadian government to establish a boundary between the province of British Columbia and the state of Alaska on the Stikine River. In 1883, he became chief engineer for the Esquimalt and Nanaimo Railway The Island Rail Corridor, previously the Esquimalt & Nanaimo Railway (E&N Railway), is a railway operation on Vancouver Island and is the only remaining railway on Vancouver Island after the closure of the Englewood Railway in November 2017.

Canadian Pacific Survey
The Canadian Pacific Survey or Canadian Pacific Railway Survey comprised many distinct geographical surveys conducted during the 1870s and 1880s, designed to determine the ideal route of the Canadian Pacific Railway. Although much of the survey's activity focused on locating suitable mountain passes through the Canadian Rockies, Selkirk Mountains, Monashee Mountains, Canadian Cascades and Coast Mountains of western Canada, locating the best route across the rugged terrain of the Canadian Shield north of Lake Superior was also a primary goal. The survey played an important role in the exploration of Canada, especially in the mapping of hitherto-uncharted parts of British Columbia. In British Columbia, survey work was overseen by Walter Moberly, a former Colony of British Columbia land official and cabinet member, and involved steamboat support vessels on the Arrow Lakes and Columbia River, and on Kootenay Lake, Shuswap Lake, Seton Lake and others. The survey entailed the first d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scoria
Scoria is a pyroclastic, highly vesicular, dark-colored volcanic rock that was ejected from a volcano as a molten blob and cooled in the air to form discrete grains or clasts.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. It is typically dark in color (generally dark brown, black or purplish-red), and basaltic or andesitic in composition. Scoria is relatively low in density as a result of its numerous macroscopic ellipsoidal vesicles, but in contrast to pumice, all scoria has a specific gravity greater than 1, and sinks in water. The holes or vesicles form when gases that were dissolved in the magma come out of solution as it erupts, creating bubbles in the molten rock, some of which are frozen in place as the rock cools and solidifies. Scoria may form as part of a lava flow, typically near its surface, or as fragmental ejecta (lapilli, blocks and bombs), for inst ...

Breadcrust Bomb
A volcanic bomb or lava bomb is a mass of partially molten rock (tephra) larger than 64 mm (2.5 inches) in diameter, formed when a volcano ejects viscous fragments of lava during an eruption. Because volcanic bombs cool after they leave the volcano, they are extrusive igneous rocks. Volcanic bombs can be thrown many kilometres from an erupting vent, and often acquire aerodynamic shapes during their flight. Bombs can be extremely large; the 1935 eruption of Mount Asama in Japan expelled bombs measuring 5–6 m (16-20 ft) in diameter up to from the vent. Volcanic bombs are a significant volcanic hazard, and can cause severe injuries and death to people in an eruption zone. One such incident occurred at Galeras volcano in Colombia in 1993; six people near the summit were killed and several seriously injured by lava bombs when the volcano erupted unexpectedly. On July 16, 2018, 23 people were injured on a tour boat near the Kilauea volcano as a result of a basketb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lava Lake
Lava lakes are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. The term is used to describe both lava lakes that are wholly or partly molten and those that are solidified (sometimes referred to as ''frozen lava lakes''). Formation Lava lakes can form in three ways: *from one or more vents in a crater that erupts enough lava to partially fill the crater; or *when lava pours into a crater or broad depression and partially fills the crater; or *atop a new vent that erupts lava continuously for a period of several weeks or more and slowly builds a crater progressively higher than the surrounding ground. Behaviors Lava lakes occur in a variety of volcanic systems, ranging from the basaltic Erta Ale lake in Ethiopia and the basaltic andesite volcano of Villarrica, Chile, to the unique phonolitic lava lake at Mt. Erebus, Antarctica. Lava lakes have been observed to exhibit a range of behaviours. A "constantly circulat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vesicular Texture
Vesicular texture is a volcanic rock texture characterized by a rock being pitted with many cavities (known as vesicles) at its surface and inside. This texture is common in aphanitic, or glassy, igneous rocks that have come to the surface of the earth, a process known as extrusion. As magma rises to the surface the pressure on it decreases. When this happens gasses dissolved in the magma are able to come out of solution, forming gas bubbles (the cavities) inside it. When the magma finally reaches the surface as lava and cools, the rock solidifies around the gas bubbles and traps them inside, preserving them as holes filled with gas called vesicles. A related texture is amygdaloidal in which the volcanic rock, usually basalt or andesite, has cavities, or vesicles, that are filled with secondary minerals, such as zeolites, calcite, quartz, or chalcedony. Individual cavity fillings are termed amygdules (American usage) or amygdales (British usage). Sometimes these can be source ...
