Kostal Volcano
Kostal Cone, also called Kostal Volcano and Fire Mountain, is a young cinder cone in Wells Gray Provincial Park in east-central British Columbia, Canada. It rises from the northeast shore of Kostal Lake in the Cariboo Mountains. With an elevation of , Kostal Cone is one of the lowest volcanoes in the Wells Gray-Clearwater volcanic field. There has been activity at this site as recently as 7,600 years ago, though more likely less than 1,000 years ago. Kostal Cone is too young for the commonly used potassium-argon dating technique (usable on specimens over 100,000 years old), and no charred organic material for radiocarbon dating has been found. However, the uneroded structure of the cone with the existence of trees on its flanks and summit have it an area for dendrochronology studies, which reveals the growth of tree-ring patterns. Tree-growth data has revealed an age of 400 years for Kostal Cone, making it the youngest volcano in the Wells Gray-Clearwater volcanic field and one of ...

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] |
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 ...

Holocene Volcanoes
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.

Mahood Lake
Mahood Lake is a lake in the South Cariboo region of the Interior of British Columbia in Wells Gray Provincial Park. It is drained by the Mahood River, a tributary of the Clearwater River which has cut a deep canyon into Cambrian rocks and Pleistocene glacial moraines. Mahood Lake is fed by the short Canim River, which drains nearby Canim Lake to the west via Canim Falls and Mahood Falls.Neave, Roland (2015). ''Exploring Wells Gray Park'', 6th edition. Wells Gray Tours, Kamloops, BC. . The lake is 629 metres in elevation, 197 metres deep at its deepest point, approximately 33.5 km² in area, in length (east to west) and a maximum of in width. Mount Mahood is immediately south of the lake and rises to . Discovery and naming There are no written records about First Nations visits to Mahood Lake, but they did use this valley because pictographs can be seen about halfway along the south shore. The Mahood Lake area was the centre of considerable attention between 1872 and 187 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Dragon Cone
Dragon Cone is a monogenetic cinder cone located in Wells Gray Provincial Park in east-central British Columbia. It is the source of a long lava flow, called Dragon's Tongue. This lava covered the floor of narrow Falls Creek Valley and terminated at the Clearwater River, damming it to a height of and raising the level of existing Clearwater Lake upstream. Geologists have recovered some peat buried by the lava and radiocarbon dating produced an age of 7560 years plus or minus 100 years.Hickson, Cathie with Hollinger, Jason (2014). ''Wells Gray Rocks''. Thompson Rivers University, Kamloops, BC. Flows from nearby Flourmill Cone, Kostal Cone and Spanish Lake Cones rest on glaciated bedrock without an intervening paleosol, suggesting an early Holocene age. Visits to Dragon Cone are very rare due to difficult access. The nearest trail is the overgrown Kostal Lake Trail, over to the south. Falls Creek is impassable for boats.
