The Kitsu Plateau is a lava plateau in northern British Columbia, Canada, located east of Mess Lake in Mount Edziza Provincial Park. [1] It is named in association with Kitsu Peak and Kitsu Creek. Kitsu in the Tahltan language is the word for the northern lights. [2]
Mount Edziza, sometimes called Edziza Mountain or Edziza Peak, is a stratovolcano in Cassiar Land District of northwestern British Columbia, Canada. It is located on the Big Raven Plateau of the Tahltan Highland which extends along the western side of the Stikine Plateau. The mountain has an elevation of 2,786 metres, making it the highest volcano of the Mount Edziza volcanic complex. However, it had an elevation of at least 3,396 metres before its original summit was likely destroyed by a violent, climactic eruption in the geologic past; its current flat summit contains an ice-filled, 2-kilometre (1.2-mile) in diameter crater. Mount Edziza contains several lava domes, cinder cones and lava fields on its flanks, as well as an ice cap that is characterized by several outlet glaciers stretching out to lower altitudes. All sides of the mountain are drained by tributaries of Mess Creek and Kakiddi Creek which are situated within the Stikine River watershed.
The Spectrum Range, formerly gazetted as the Spectrum Mountains and the Rainbow Mountains, is a small mountain range in Cassiar Land District of northwestern British Columbia, Canada. Located at the southern end of the Tahltan Highland, it borders the Skeena Mountains in the east and the Boundary Ranges of the Coast Mountains in the west. The Spectrum Range is surrounded by the Arctic Lake Plateau in the southwest and the Kitsu Plateau in the northwest, both of which contain volcanic features such as cinder cones. It lies at the southern end of the Mount Edziza volcanic complex which includes the two neighbouring plateaus as well as Mount Edziza and the Big Raven Plateau to the north. The mountain range is drained on all sides by streams within the Stikine River watershed and, unlike Mount Edziza to the north, contains relatively small separate glaciers. Mount Edziza Provincial Park is the main protected area surrounding the Spectrum Range.
Tsekone Ridge, also called Tsekone Peak and Black Knight Cone, is an isolated ridge on the Big Raven Plateau of the Tahltan Highland in northwestern British Columbia, Canada. It is located southeast of Telegraph Creek at the north side of Mount Edziza Provincial Park between Eve Cone and Mount Edziza.
The Ash Pit is an inactive volcanic crater, located on the southern edge of the Kitsu Plateau in British Columbia, Canada. It is Holocene in age and may be the youngest feature of the Mount Edziza volcanic complex. It is within the Northern Cordilleran Volcanic Province and is part of the Pacific Ring of Fire, that includes over 160 active volcanoes.
The Big Raven Plateau is an intermontane plateau in Cassiar Land District of northwestern British Columbia, Canada. It lies on the Tahltan Highland and is surrounded by several valleys, including those of Mess Creek, Kakiddi Creek, Chakima Creek, Walkout Creek and the Klastline River. The plateau is drained by many small streams that flow into these neighbouring valleys and, unlike the valleys, it is relatively barren of vegetation. Stream erosion has resulted in the creation of canyons with intervening ridges on the eastern and western sides of the plateau, resulting in the creation of rugged terrain. The plateau is in Mount Edziza Provincial Park which is one of the largest provincial parks in British Columbia. Access to the Big Raven Plateau is mainly by aircraft or by a network of footpaths from surrounding roads.
The Mount Edziza volcanic complex is a group of volcanoes and associated lava flows in northwestern British Columbia, Canada. Located on the Tahltan Highland, it is 40 kilometres southeast of Telegraph Creek and 85 kilometres southwest of Dease Lake. The complex encompasses a broad, steep-sided lava plateau that extends over 1,000 square kilometres. Its highest summit is 2,786 metres in elevation, making the MEVC the highest of four large complexes in an extensive north–south trending volcanic region. It is obscured by an ice cap characterized by several outlet glaciers that stretch out to lower altitudes.
Tadekho Hill is an isolated hill in the Northern Interior of British Columbia, Canada, located 64 km (40 mi) southwest of Tatogga and 10 km (6 mi) southwest of Kitsu Peak. It lies at the southwestern end of Mount Edziza Provincial Park.
The Mess Lake Lava Field is a volcanic field associated with the Mount Edziza volcanic complex of the Northern Cordilleran Volcanic Province in northwestern British Columbia, Canada. It lies northwest of the Spectrum Range on the Kitsu Plateau and consists of young basaltic lava flows and tephra. The source for the basaltic lava and tephra was three cinder cones, including Mess Lake Cone and The Ash Pit, which may be the youngest volcanic feature of the Mount Edziza volcanic complex.
The Little Iskut River is a tributary of the Iskut River in the northwest part of the province of British Columbia, Canada, in Cassiar Land District. From its source at Little Ball Lake in Mount Edziza Provincial Park, the Little Iskut River flows about 45 km (28 mi), generally north to the vicinity of Mowdale Lake, then southeast and south to the Iskut River just below Cascade Falls. The Little Iskut River is part of the Stikine River drainage basin, as the Iskut River is a major tributary of the Stikine.
The Big Raven Formation is a stratigraphic unit of Quaternary age in northwestern British Columbia, Canada. It is the youngest and least voluminous geological formation of the Mount Edziza volcanic complex (MEVC); it overlies at least six older formations of this volcanic complex. The main volcanic rocks of the Big Raven Formation are alkali basalts and hawaiites, although a small volume of trachyte comprises the Sheep Track Member. These rocks were deposited by volcanic eruptions in the last 20,000 years during the latest magmatic cycle of the MEVC. Alkali basalt and hawaiite are in the form of lava flows and small volcanic cones while trachyte of the Sheep Track Member is mainly in the form of volcanic ejecta which covers an area of about 40 square kilometres.
Artifact Creek is a tributary of Stewbomb Creek and part of the Stikine River watershed in northwest part of the province of British Columbia, Canada. It flows generally southeast for roughly 13 km (8.1 mi) to join Stewbomb Creek, which flows into the Little Iskut River.In turn the Little Iskut River flows to the Iskut River, the largest tributary of the Stikine River.
Gerlib Creek is a tributary of Bourgeaux Creek and part of the Stikine River watershed in northwest part of the province of British Columbia, Canada. It flows generally east and south for roughly 10.5 km (6.5 mi) to join the Bourgeaux Creek, a tributary of the Little Iskut River, which in turn is a tributary of the Iskut River, the largest tributary of the Stikine River.
Kitsu Creek is a tributary of Mess Creek and part of the Stikine River watershed in northwest part of the province of British Columbia, Canada. It flows generally northwest and north for roughly 22.5 km (14.0 mi) to join Mess Creek, a tributary of the Stikine River.
