Mount Edziza Provincial Park is a provincial park in Cassiar Land District of northern British Columbia, Canada. It was established on 27 July 1972 to showcase the Mount Edziza volcanic complex and the surrounding Tahltan Highland.
Mount Edziza, known to the local Tahltan people as Tenh Dẕetle, is a volcanic mountain 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. Mount Edziza has an elevation of 2,786 metres and a topographic prominence of 1,750 metres, making it the highest point of the Mount Edziza volcanic complex and one of Canada's ultra-prominent peaks. However, it had an elevation of at least 3,396 metres before its formerly cone-shaped summit was likely destroyed by a violent, climactic eruption in the geologic past; its current flat summit contains an ice-filled, 2-kilometre-in diameter (1.2-mile) crater. The mountain 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 Mount Edziza 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.
Sidas Cone is a cinder cone on the Big Raven Plateau at the northern end of Mount Edziza Provincial Park in British Columbia, Canada. Its name, meaning "cut oneself with a knife" in the Tahltan language, is descriptive of the breach that has cut the cone into two symmetrical halves.
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.
Level Mountain is a large volcanic complex in the Northern Interior of British Columbia, Canada. It is located 50 kilometres north-northwest of Telegraph Creek and 60 kilometres west of Dease Lake on the Nahlin Plateau. With a maximum elevation of 2,164 metres, it is the second-highest of four large complexes in an extensive north–south trending volcanic region. Much of the mountain is gently-sloping; when measured from its base, Level Mountain is about 1,100 metres tall, slightly taller than its neighbour to the northwest, Heart Peaks. The lower, broader half of Level Mountain consists of a shield-like structure while its upper half has a more steep, jagged profile. Its broad summit is dominated by the Level Mountain Range, a small mountain range with prominent peaks cut by deep valleys. These valleys serve as a radial drainage for several small streams that flow from the mountain. Meszah Peak is the only named peak in the Level Mountain Range.
Nahta Cone is a small cinder cone in Cassiar Land District of northwestern British Columbia, Canada. It has an elevation of 1,670 metres and lies near the northern edge of the Arctic Lake Plateau, a glacially scored plateau of the Tahltan Highland which in turn extends along the western side of the Stikine Plateau. The cone is about 70 kilometres south-southeast of the community of Telegraph Creek and lies in the southwestern corner of Mount Edziza Provincial Park, one of the largest provincial parks in British Columbia.
Wetalth Ridge is an isolated ridge in northern British Columbia, Canada, located 74 km (46 mi) southwest of Tatogga and south of Telegraph Creek. It lies on the southwest side of Little Arctic Lake at the southwest corner of Mount Edziza Provincial Park.
Pillow Ridge is a ridge of the Tahltan Highland in northern British Columbia, Canada, located southeast of Telegraph Creek. It extends northwest from Mount Edziza in Mount Edziza Provincial Park.
Outcast Hill is an isolated hill in northern British Columbia, Canada, located southeast of Mess Lake. It lies at the southern end of Mount Edziza Provincial Park.
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 Kitsu Plateau is a small 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, Nagha Creek and Raspberry Creek. The plateau is drained by many small streams that flow into these neighbouring valleys and, unlike the valleys, it is relatively barren of vegetation. Surrounding the Kitsu Plateau is Mount Edziza Provincial Park which is one of the largest provincial parks in British Columbia. Access to this remote plateau is mainly by aircraft since motorized vehicles are prohibited from entering Mount Edziza Provincial Park.
Tennena Cone, alternatively Icebridge Cone, is a small volcanic cone in Cassiar Land District of northwestern British Columbia, Canada. It has an elevation of 2,390 metres and lies on the western flank of Ice Peak, the prominent south peak of Mount Edziza. The cone is almost completely surrounded by glacial ice of Mount Edziza's ice cap which covers an area of around 70 square kilometres. Tennena Cone is 200 metres high, 1,200 metres long and up to 600 metres wide, its symmetrical structure resembling a black pyramid. The cone and the surrounding area are in Mount Edziza Provincial Park which also includes the Spectrum Range to the south.
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.
Exile Hill is an isolated hill in the Spectrum Range of northern British Columbia, Canada, located southeast of Mess Lake. It lies at the southern end of Mount Edziza Provincial Park.
The volcanic history of the Northern Cordilleran Volcanic Province presents a record of volcanic activity in northwestern British Columbia, central Yukon and the U.S. state of easternmost Alaska. The volcanic activity lies in the northern part of the Western Cordillera of the Pacific Northwest region of North America. Extensional cracking of the North American Plate in this part of North America has existed for millions of years. Continuation of this continental rifting has fed scores of volcanoes throughout the Northern Cordilleran Volcanic Province over at least the past 20 million years and occasionally continued into geologically recent times.
Edziza obsidian is a naturally formed volcanic glass found at the Mount Edziza volcanic complex in northwestern British Columbia, Canada. It occurs in at least four geological formations of the volcanic complex and was widely used by indigenous peoples during the pre-Columbian era. As a result of its widespread use, Edziza obsidian has been found in several archaeological sites throughout the Pacific Northwest.
Tennaya Creek is a tributary of Kakiddi Creek, which in turn is a tributary of the Klastline River, part of the Stikine River watershed in northwest part of the province of British Columbia, Canada. It flows generally west for about 16 km (9.9 mi) to join Kakiddi Creek about 19 km (12 mi) south of Kakiddi Creek's confluence with the Klastline River. Tennaya Creek's watershed covers 63.3 km2 (24.4 sq mi) and its mean annual discharge is estimated at 1.50 m3/s (53 cu ft/s). The mouth of Tennaya Creek is located about 48 km (30 mi) southeast of Telegraph Creek, about 30 km (19 mi) southwest of Iskut and about 86 km (53 mi) south-southwest of Dease Lake. Tennaya Creek's watershed's land cover is classified as 31.3% barren, 26.0% conifer forest, 17.9% snow/glacier, 12.6% herbaceous, 9.9% shrubland, and small amounts of other cover.
Tencho Glacier is a mountain glacier in northwestern British Columbia, Canada. It is located inside Mount Edziza Provincial Park on the Tahltan Highland, an upland area of the Stikine Plateau. Tencho Glacier is the source of several small streams that flow from the Mount Edziza volcanic complex.
The Edziza Formation is a stratigraphic unit of Pleistocene age in northwestern British Columbia, Canada. First described in 1984, the Edziza Formation was mapped as one of several geological formations of the Mount Edziza volcanic complex. It overlies at least four other geological formations of this volcanic complex that differ in age and composition. The main volcanic rock comprising the Edziza Formation is trachyte which was deposited by volcanic eruptions at the end of the third magmatic cycle of the Mount Edziza volcanic complex 0.9 million years ago.
