Loss Creek (Canada)
Loss Creek is a stream in the Capital Regional District of British Columbia, Canada. Located on southern Vancouver Island, it flows through a long, steep-sided valley to the Strait of Juan de Fuca on the Pacific Ocean. Geology The stream mostly follows an unusually long, straight, narrow, and steep-sided valley, between the Jordan Ridge to the south and the San Juan Ridge to the north. This valley is the surface trace of the Leech River Fault, a major regional fault that marks the contact between the oceanic basalts of the Crescent Terrane (part of Siletzia) to the south, and the metamorphic rocks of the Pacific Rim Terrane to the north. The Leech River fault is straight because it was originally a strike-slip fault (moving horizontally), but now it is being thrust under Vancouver Island. As the Pacific Rim rock is uplifted and exposed it rapidly erodes; this releases the occasional gold deposit, which then collects in placer deposits in Loss Creek. Natural history The lower r ...

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] |
Siletzia
Siletzia is a massive formation of early to middle Eocene epoch marine basalts and interbedded sediments in the forearc of the Cascadia subduction zone, on the west coast of North America. It forms the basement rock under western Oregon and Washington and the southern tip of Vancouver Island. It is now fragmented into the Siletz and Crescent terranes. Siletzia corresponds geographically to the Coast Range Volcanic Province (or Coast Range basalts), but is distinguished from slightly younger basalts that erupted after Siletzia accreted to the continent and differ in chemical composition. The Siletzia basalts are tholeiitic, a characteristic of mantle-derived magma erupted from a spreading ridge between plates of oceanic crust. The younger basalts are alkalic or calc-alkaline, characteristic of magmas derived from a subduction zone. This change of composition reflects a change from marine to continental volcanism that becomes evident around 48 to 42 Ma (millions of y ...

Rivers Of Vancouver Island
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as Stream#Creek, creek, Stream#Brook, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to Geographical feature, geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "Burn (landform), burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from Precipitation (meteorology), precipitation through a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Renfrew
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhou ...

Juan De Fuca Marine Trail
The Juan de Fuca Marine Trail is a rugged wilderness hiking trail located within Juan de Fuca Provincial Park along the southwestern coast of Vancouver Island. The trail stretches from China Beach, 35 km west of Sooke, to Botanical Beach, just outside Port Renfrew. Panoramic views of the coastline, Juan de Fuca Strait and the Olympic Mountains can be seen from many points along this rainforest trail. Lucky are those who spot a pod of whales, but it is not uncommon to view sea lions, bald eagles, herons and other wildlife. It is a stunning trail of moderate difficulty. The trail can be hiked in part, as a day hike, or backpacked in its entirety in four to six days. Unlike the longer West Coast Trail (), the Juan de Fuca Trail does not require a reservation; however, there is a backcountry camping fee of $10 per person/per night. It is also suggested to plan ahead if travelling with a large group. Some campsites are quite small and so arriving early to guarantee a spot i ...

British Columbia Highway 14
British Columbia Highway 14, named the West Coast (Sooke) Highway is the southernmost numbered route in the province of British Columbia. An east-west highway on the southwestern coast of Vancouver Island in the Capital Regional District, it is sometimes known as the ''Juan de Fuca Highway'', as well as ''Sooke Road'', Sooke being one of the largest communities that the highway passes through. Highway 14 first opened in 1953, extending west from Colwood, a suburb of Victoria, to the coastal community of Jordan River, and was extended all the way west to the remote community of Port Renfrew by 1975. The highway's eastern terminus was relocated to northern Langford in 2002. Outside of urban areas the route has exceptionally winding, curving and hilly stretches. Some of the sharper corners have oversized, freeway-style, jersey barriers instead of the more typical steel crash rails, mostly to prevent an out-of-control vehicle from falling off a cliff into the Strait of Juan de Fu ...

Jordan River, British Columbia
Jordan River, founded as and still officially gazetted as River Jordan, is a small settlement on the west coast of Vancouver Island, British Columbia, Canada, located approximately west of Victoria. Established as a logging camp in the late 19th century, Jordan River has Vancouver Island's second hydroelectric power plant. It is popular amongst winter surfers. The eastern terminus of the Juan de Fuca Trail is at China Beach, west of Jordan River. History In 1790, the Spanish navigator and explorer Lieutenant Francisco de Eliza rebuilt a Spanish fort at Nootka Sound and subsequently explored the area between Nootka Sound and present day Victoria, BC. Originally named Rio Hermoso by his Sub-Lieutenant Manuel Quimper on June 14, 1790, the name was changed later that year to Rio Jordan when the Carta Reducida was made by Gonzalo López de Haro. The name change from Rio Hermoso to Rio Jordan is attributed to Francisco de Eliza's chaplain, Alejandro Jordan. Subsequent charting ...

Juan De Fuca Provincial Park
Juan de Fuca Provincial Park is a provincial park located on the west coast of Vancouver Island in British Columbia, Canada. The park was established on April 4, 1996 by combining three former parks - China Beach, Loss Creek, and Botanical Beach - into one provincial park. It is the location of the majority of the Juan de Fuca Marine Trail, which is a southern compliment to the West Coast Trail within Pacific Rim National Park Reserve. History The region was recognized as biologically significant, and Josephine Tilden of the University of Minnesota installed the first marine research station in the Pacific Northwest at Botanical Beach in 1901. The University of Minnesota maintained a research station here for five years, but they left in 1906. Conway MacMillan resigned from the University of Minnesota after the university refused to take ownership of land in a different country. After the departure of the University of Minnesota, the University of British Columbia, University o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strike-slip
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Leech River Fault
The Leech River Fault extends across the southern tip of Vancouver Island in British Columbia, Canada, creating the distinctively straight, narrow, and steep-sided valley, occupied by Loss Creek and two reservoirs, that runs from Sombrio Point (southeast of Port Renfrew and Sombrio Beach) due east to the Leech River, and then turns southeast to run past Victoria. It is a thrust fault that marks the northernmost exposure of the Crescent Terrane (part of Siletzia), where basalt of the Metchosin Igneous Complex (correlative with the Crescent Formation on the Olympic Peninsula) is dragged under Vancouver Island by the subducting Juan de Fuca Plate. About ten kilometers north the nearly parallel ''San Juan Fault'' marks the southern limit of rock of the Wrangellia terrane, which underlies most of Vancouver Island. Between these two northeast-dipping thrust faults are the ''Leech River Complex'' and (near Port Renfrew, but also outcrops near Victoria) the ''Pandora Peak Unit''. T ...
