Mount Ray (British Columbia)
Mount Ray, also known as Ray Mountain, is a subglacial mound in Wells Gray Provincial Park, British Columbia, Canada. Mount Ray last erupted during the Pleistocene. It is part of the Wells Gray-Clearwater volcanic field. The lava flows were restricted by larger masses of ice in the valleys on either side of Mount Ray, so the lava did not extend any great distance from its origin.Neave, Roland (2015). ''Exploring Wells Gray Park'', 6th edition. Wells Gray Tours, Kamloops, BC. .Hickson, Cathie with Hollinger, Jason (2014). ''Wells Gray Rocks''. Thompson Rivers University, Kamloops, BC. Mount Ray was named for John Bunyan Ray, the first settler in the Clearwater Valley. He was born in 1878 in North Carolina and came to the Valley in 1909. He cleared land and established a farm in the wilderness south of Clearwater Lake. He married Alice Ludtke in 1932 and they raised three children, Nancy, Doug and Bob. The Ray family decided to move to the North Thompson Valley in 1946, mainly so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
North Thompson River
The North Thompson River is the northern branch of the Thompson River, the largest tributary of the Fraser River, in the Canadian province of British Columbia. It originates at the toe of the Thompson Glacier in the Premier Range of the Cariboo Mountains, west of the community of Valemount. The river flows generally south through the Shuswap Highland towards Kamloops where it joins the South Thompson River to form the main stem Thompson River. For most of its length, the river is paralleled by Highway 5, and the Canadian National Railway (both of which cross the river a couple of times). The North Thompson passes by several small communities, the most notable being Blue River, Clearwater, and Barriere. Tributaries of the North Thompson River include Canvas Creek, the Albreda River, Thunder River, Mud Creek, Blue River, Mad River, Raft River, Clearwater River, and Barrière River. The North Thompson's largest tributary is the Clearwater River, which joins at the town of Cle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene Volcanoes
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...

Two-thousanders Of British Columbia
Two-thousanders are mountains that have a height of at least 2,000 metres above sea level, but less than 3,000 metres. The term is used in Alpine circles, especially in Europe (e.g. German: ''Zweitausender''). The two photographs show two typical two-thousanders in the Alps that illustrate different types of mountain. The Säuling (top) is a prominent, individual peak, whereas the Schneeberg (bottom) is an elongated limestone massif. In ranges like the Allgäu Alps, the Gesäuse or the Styrian-Lower Austrian Limestone Alps the mountain tour descriptions for mountaineers or hikers commonly include the two-thousanders, especially in areas where only a few summits exceed this level. Examples from these regions of the Eastern Alps are: * the striking Nebelhorn (2,224 m) near Oberstdorf or the Säuling (2,047 m) near Neuschwanstein, * the Admonter Reichenstein (2,251 m), Eisenerzer Reichenstein (2,165 m), Großer Pyhrgas (2,244 m) or Hochtor (2,369&n ...

Volcanoes Of British Columbia
British Columbia is the westernmost province of Canada, bordered by the Pacific Ocean. With an area of it is Canada's third-largest province. The province is almost four times the size of the United Kingdom and larger than every United States state except Alaska. It is bounded on the northwest by the U.S. state of Alaska, directly north by Yukon and the Northwest Territories, on the east by Alberta, and on the south by the U.S. states of Washington, Idaho, and Montana. Formerly part of the British Empire, the southern border of British Columbia was established by the 1846 Oregon Treaty. The province is dominated by mountain ranges, among them the Canadian Rockies but dominantly the Coast Mountains, Cassiar Mountains, and the Columbia Mountains. Most of the population is concentrated on the Pacific coast, notably in the area of Vancouver, located on the southwestern tip of the mainland, which is known as the Lower Mainland. It is the most mountainous province of Canada. Statist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fissure Vent
A fissure vent, also known as a volcanic fissure, eruption fissure or simply a fissure, is a linear volcanic vent through which lava erupts, usually without any explosive eruption, explosive activity. The vent is often a few metres wide and may be many kilometres long. Fissure vents can cause large flood basalts which run first in lava channels and later in lava tubes. After some time, the eruption tends to become focused at one or more spatter cones. Small fissure vents may not be easily discernible from the air, but the crater rows (see Laki) or the canyons (see Eldgjá) built up by some of them are. The Dike_(geology)#Magmatic_dikes, dikes that feed fissures reach the surface from depths of a few kilometers and connect them to deeper magma chamber, magma reservoirs, often under volcanic centers. Fissures are usually found in or along rifts and rift zones, such as Iceland and the East African Rift. Fissure vents are often part of the structure of shield volcanoes. Icelan ...

Volcanism Of Canada
Volcanic activity is a major part of the geology of Canada and is characterized by many types of volcanic landform, including lava flows, volcanic plateaus, lava domes, cinder cones, stratovolcanoes, shield volcanoes, submarine volcanoes, calderas, diatremes, and maars, along with less common volcanic forms such as tuyas and subglacial mounds. Though Canada's volcanic history dates back to the Precambrian eon, at least 3.11 billion years ago, when its part of the North American continent began to form, volcanism continues to occur in Western and Northern Canada in modern times, where it forms part of an encircling chain of volcanoes and frequent earthquakes around the Pacific Ocean called the Pacific Ring of Fire. Because volcanoes in Western and Northern Canada are in relatively remote and sparsely populated areas and their activity is less frequent than with other volcanoes around the Pacific Ocean, Canada is commonly thought to occupy a gap in the Ring of Fire between the ...

Kostal Lake
Kostal Lake is a lake located in Wells Gray Provincial Park, east-central British Columbia, Canada. It is located west of Murtle Lake and east of Clearwater Lake. Naming Kostal Lake was named by Angus Horne in 1936 for Frank Kostal, one of the many trappers and prospectors who visited this remote region during the first quarter of the 20th century. Kostal had a cabin by the lake which he used when collecting animals from his trapline on Kilpill Mountain. Access Visits to Kostal Lake are rare due to difficult access. A trail from Clearwater Lake Campground was built in 1971 and originally extended to McDougall Lake and the west arm of Murtle Lake. The section beyond Kostal Lake has been impassable since the mid-1980s. The rest of the trail was permanently closed by B.C. Parks in 2013 and only the first from the campground as far as the Dragon's Tongue lava flow can still be used. A rigorous access route is still possible by canoe up File Creek, then a cross-country hike over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clearwater Lake (British Columbia)
Clearwater Lake is one of six large lakes in Wells Gray Provincial Park in east-central British Columbia, Canada,. The Clearwater River enters the lake at its north end, flowing from Hobson Lake and Azure Lake, and also drains the lake. There are several small streams that flow into Clearwater Lake, but it has no significant tributaries.Neave, Roland (2015). ''Exploring Wells Gray Park'', 6th edition. Wells Gray Tours, Kamloops, BC. . Formation The basin occupied by Clearwater Lake was scoured by glaciers during several ice ages, including the Wisconsin Ice Age which ended in this region about 10,000 years ago. The basin subsequently filled with meltwater, but its depth has never been measured reliably. The deepest point is believed to be just east of Diver's Bluff. When Dragon Cone erupted about 8,500 years ago, the lava flowed southwest to the Clearwater River, damming it to a height of and raising the level of existing Clearwater Lake just upstream. This flow is just one ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
