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. It contains a 70-square-kilometre (27-square-mile) ice cap that is characterized by several outlet glaciers stretching out to lower altitudes. Mount Edziza also contains several lava domes, cinder cones and lava fields on its flanks. 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 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.
Williams Cone is a satellite cone of Mount Edziza, located 36 km (22 mi) east of Telegraph Creek. It lies just off the northern edge of the Tencho Icefield and is one of the many postglacial cinder cones that lie on the Mount Edziza volcanic complex. Williams Cone last erupted about 1,350 years ago along with other nearby volcanoes, such as the well-preserved Eve Cone.
Coffee Crater is a well-preserved cinder cone south of Mount Edziza, British Columbia, Canada. It was formed during the Holocene period. It is within the Snowshoe lava field, part of the Mount Edziza volcanic complex.
The Desolation Lava Field is a volcanic field associated with the Mount Edziza volcanic complex in British Columbia, Canada. It covers 150 km2 (58 sq mi) on the northern end of the Mount Edziza volcanic complex and is the largest area of the youngest lava flows. The longest lava flow from the field and the volcanic complex, is about 12 km (7.5 mi) long. Eve Cone, in the middle of the field, is one of the most symmetrical and best preserved cinder cones in Canada.
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.
Cocoa Crater is a cinder cone in the Stikine Country of northwestern British Columbia, Canada. It is located 38 km southeast of Telegraph Creek and 8 m (26 ft) southwest of Mount Edziza. Cocoa Crater is one of the 30 cinder cones around the Mount Edziza complex that formed in the year 700. The ash around Cocoa Crater is quite deep, its summit is a jet black color and its summit is red. It is quite a different color from the brown color of Coffee Crater, which is to the south of Cocoa Crater.
Nahta Cone is a cinder cone in northern British Columbia, Canada, located 69 km (43 mi) southwest of Tatogga, 2 km (1 mi) west of Wetalth Ridge and south of Telegraph Creek. It lies in the southwestern corner of 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.
Kana Cone is a red nested cinder cone in northern British Columbia, Canada, located northeast of Eve Cone in Mount Edziza Provincial Park. Adopted 2 January 1980 on 104G/12, as submitted by Geological Survey of Canada.
The Snowshoe Lava Field is a volcanic field associated with the Mount Edziza volcanic complex in northern British Columbia, Canada. It is on the southern end of the Big Raven Plateau and is an area of young lava flows.
Cache Hill is a cinder cone in northern British Columbia, Canada. It is thought to have last erupted in the Holocene period. Once used as an airdrop for food and supplies by the Geological Survey of Canada, hence its name, it is located north of Raspberry Pass in Mount Edziza Provincial Park.
The Mount Edziza volcanic complex is a linear 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 above sea level, making the MEVC the highest of four large complexes in an extensive north–south trending volcanic region. An ice cap obscures the highest summit which is characterized by several outlet glaciers stretching out to lower altitudes.
Keda Cone, sometimes mistakenly called Kena Cone and sometimes referred to by the numeronym SLF-9, is a cinder cone in northwestern British Columbia, Canada. It is located in the Snowshoe Lava Field of Mount Edziza Provincial Park, having last erupted during the Holocene epoch.
Klastline Cone is a cinder cone in northwestern British Columbia, Canada, located near Mount Edziza in Mount Edziza Provincial Park. It last erupted during the Pleistocene epoch.
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.
The Big Raven Formation is a stratigraphic unit of Holocene age in northwestern British Columbia, Canada.
