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. 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.
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.
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.
The Sheep Track Member is a stratigraphic unit of the Big Raven Formation, part of the Mount Edziza volcanic complex in northwestern British Columbia, Canada. It consists of pumice from an explosive eruption that fell over an area about 40 square kilometres. The pumice is of comenditic trachyte composition and reaches a thickness of up to 2 metres along the western edge of Tencho Glacier.
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.
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 Klastline River is a tributary of the Stikine River in northwestern British Columbia, Canada. It flows generally northwest about 70 km (43 mi) to join the Stikine River, which flows southwest across the Canada–United States border into Alaska where it empties into various straits of the Inside Passage. The Klastline River flows through Mount Edziza Provincial Park which lies within the traditional territory of the Tahltan people. Klastline means "confluence" or "junction of waters" in the Tahltan language.
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.
The Big Raven Formation is a stratigraphic unit of Holocene 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 trachyte is also present. They were deposited by volcanic eruptions in the last 12,000 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 is mainly in the form of volcanic ejecta covering an area of about 40 square kilometres. The Sheep Track Member is the only named sub-unit of the Big Raven Formation.

The Mount Edziza volcanic complex (MEVC) in British Columbia, Canada, has a long history of volcanism that spans more than six million years. It occurred during five cycles of magmatic activity which were characterized by 13 periods of eruptive activity. This volcanism has led to the formation of several types of volcanic landforms, including cinder cones, stratovolcanoes, subglacial volcanoes, shield volcanoes, lava domes and lava fields. The 1,000-square-kilometre (390-square-mile) plateau comprising the MEVC owes its origin to successive eruptions of highly mobile lava flows. Volcanic rocks such as alkali basalt, hawaiite, trachybasalt, benmoreite, tristanite, mugearite, trachyte, comendite and pantellerite were deposited by multiple eruptions of the MEVC; the latter eight were produced by varying degrees of magmatic differentiation in underground magma reservoirs.
Tenchen Glacier is located on the eastern flank of Mount Edziza in northwestern British Columbia, Canada. It lies within an immense cirque whose headwall has breached the eastern side of Mount Edziza's summit crater. At the head of Tenchen Glacier are icefalls that drape down shear, 300-metre-high (980-foot) cliffs from the breached eastern crater rim; permanent ice fills the summit crater. Meltwater from Tenchen Glacier feeds Tenchen Creek which eventually merges with Kakiddi Creek.
