The Anahim Volcanic Belt is a 600 km (373 mi) long volcanic belt, stretching from just north of Vancouver Island to near Quesnel, British Columbia, Canada. The Anahim Volcanic Belt has had three main magmatic episodes: 15–13 Ma, 9–6 Ma, and 3–1 Ma. The volcanoes generally become younger eastward at a rate of 2 cm (0.8 in) to 3.3 cm (1.3 in) a year. The Nazko Cone, which last erupted only 7,200 years ago, is the youngest Anahim volcano. These volcanoes are thought to have formed as a result of the North American Plate sliding westward over a long-lived center of upwelling magma called the Anahim hotspot. The hotspot is thought to be similar to the one feeding the Hawaiian Islands.
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.
The Chilcotin River is a 241-kilometre (150 mi) long tributary of the Fraser River in southern British Columbia, Canada. It drains the Chilcotin Plateau, which lies between the Fraser River and the Coast Mountains. It starts northeast of Itcha Mountain and flows generally southeast to join the Fraser about 22 km upstream from Gang Ranch.
The Interior Plateau comprises a large region of the Interior of British Columbia, and lies between the Cariboo and Monashee Mountains on the east, and the Hazelton Mountains, Coast Mountains and Cascade Range on the west. The continuation of the plateau into the United States is known there as the Columbia Plateau.
The Rainbow Range, formerly gazetted as the Rainbow Mountains, is a mountain range in British Columbia, Canada, located 40 kilometres (25 mi) northwest of Anahim Lake. Located on the western edge of the Chilcotin Plateau, the range adjoins the Coast Mountains Pacific Ranges to the south, and the Kitimat Ranges to the north. In some classification systems it is considered part of the Coast Mountains. It lies north of the Bella Coola and Atnarko Rivers and south and west of the Dean River, which curves around its north flank, and is relatively drier in climate and easier of terrain than more mountainous areas immediately west.
The Homathko River is one of the major rivers of the southern Coast Mountains of the Canadian province of British Columbia. It is one of the few rivers that penetrates the range from the interior Chilcotin Country to the coastal inlets of the Pacific Ocean. The Homathko River reaches the sea at the head of Bute Inlet, just west of the mouth of the Southgate River.
The Chilcotin Plateau is part of the Fraser Plateau, a major subdivision of the Interior Plateau of British Columbia. The Chilcotin Plateau is physically near-identical with the region of the same name, i.e. "the Chilcotin", which lies between the Fraser River and the southern Coast Mountains and is defined by the basin of the Chilcotin River and so includes montane areas beyond the plateau. East of the Chilcotin Plateau, across the Fraser River, is the Cariboo Plateau, while to the north beyond the West Road (Blackwater) River is the Nechako Plateau. West and south of the Chilcotin Plateau are various subdivisions of the Coast Mountains, including the Chilcotin Ranges which lie along the plateau's southwest.
Big Creek Provincial Park is a provincial park in British Columbia, Canada.
Itcha Ilgachuz Provincial Park is a provincial park in the Chilcotin Country of British Columbia, Canada. The park is 111,977 hectares in size and contains Far Mountain and Mount Downton, its two most prominent peaks.
Tsintsunko Lakes Provincial Park is a 333-hectare provincial park in British Columbia, Canada, located south of the Deadman River between Kamloops (SE) and Bonaparte Lake (NW). It is located on the Bonaparte Plateau. It was established April 30, 1996.
The Spectrum Range, formerly called the Spectrum Mountains and the Rainbow Mountains, is a subrange of the Tahltan Highland in the Stikine Country of northwestern British Columbia, 20 km west of the Stewart-Cassiar Highway, south of Mount Edziza and north of the Arctic Lake Plateau. The Spectrum Range falls within Mount Edziza Provincial Park. The range is lightly glaciated, as compared to the other ranges to the west. It is accessible only by foot or via helicopter; there are no roads to the range.
Tsitsutl Peak is the highest volcanic peak of the Rainbow Range in British Columbia, Canada, located within Tweedsmuir South Provincial Park, 43 km (27 mi) northwest of Anahim Lake and 44 km (27 mi) northeast of Thunder Mountain.
The Itcha Range, also known as the Itchas, is a small isolated mountain range in the West-Central Interior of British Columbia, Canada. It is located 40 km (25 mi) northeast of the community of Anahim Lake. With a maximum elevation of 2,375 m (7,792 ft), it is the lowest of three mountain ranges on the Chilcotin Plateau extending east from the Coast Mountains. Two mountains are named in the Itcha Range; Mount Downton and Itcha Mountain. A large provincial park surrounds the Itcha Range and other features in its vicinity. More than 15 animal species are known to exist in the Itcha Range area, as well as a grassland community that is limited only to this location of British Columbia. The Itcha Range is within territory which has been occupied by aboriginal peoples for millennia. This area has a relatively dry environment compared to the Coast Mountains in the west.
The Ilgachuz Range is a name given to an extinct shield volcano in British Columbia, Canada. It is not a mountain range in the normal sense, because it was formed as a single volcano that has been eroded for the past 5 million years. It lies on the Chilcotin Plateau, located some 350 kilometres (220 mi) north-northwest of Vancouver and 30 km north of Anahim Lake. The highest peak of the range is Far Mountain. The range supports a unique grassland ecosystem. This type of grassland has not been seen anywhere else in central and southern British Columbia. The climate is cool and dry; typical of higher elevations of the Interior Plateau.
Itcha Mountain is one of the two named volcanic peaks of the Itcha Range, which is located in the Chilcotin District of the Central Interior of British Columbia, Canada. It is in the Anahim Volcanic Belt, which formed when the North American Plate moved over a hotspot, similar to the one feeding the Hawaiian Islands. The Anahim Volcanic Belt includes other immediately nearby ranges, the Rainbow and Ilgachuz Ranges. Itcha Mountain is located 42 km (26 mi) northeast of Anahim Lake and 2 km (1 mi) northeast of Mount Downton, another peak of the Itcha Range. Both of these peaks are located within Itcha Ilgachuz Provincial Park, as is Far Mountain, the park's highest peak.
Far Mountain is the highest of over 13 peaks in the Ilgachuz Range in the Anahim Volcanic Belt in British Columbia, Canada. The Ilgachuz Range is one of the three major shield volcanoes that formed the Anahim Volcanic Belt when the North American Plate moved over a hotspot. This is similar to the one which feeds the Hawaiian Islands. The mountain is located in the western part of Itcha Ilgachuz Provincial Park.
Mount Downton is the highest summit of the 10 km (6 mi) diameter Itcha Range, located 40 km (25 mi) northeast of Anahim Lake and 33 km (21 mi) east of Far Mountain in the Chilcotin District of the Central Interior of British Columbia, Canada. It lies within Itcha Ilgachuz Provincial Park.
The Fraser Plateau is an intermontane plateau. It is one of the main subdivisions of the Interior Plateau located in the Central Interior of British Columbia.
South Chilcotin Mountains Provincial Park is a provincial park in British Columbia, Canada, located northwest of Lillooet, British Columbia. The park, which is 56,796 ha. in size, was established in 2010. It was created out of a portion of the Spruce Lake Protected Area.
There are 20 lakes named Long Lake in British Columbia, Canada.
