Mount Edziza is a stratovolcano in the Stikine Country of northwestern British Columbia, Canada. The volcano and the surrounding area are protected within Mount Edziza Provincial Park. It consists of multiple peaks and ridges, with several glaciers flowing in all directions. The summit is topped by an ice-filled caldera, which is almost 2 km (1 mi) wide. The three main peaks around the summit caldera are the southwest summit, the southeast summit and the north summit. Ice Peak overlaps the southern flank of Mount Edziza.
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.
The Pyramid, also called Pyramid Dome, is a young lava dome on the northeast flank of Mount Edziza in British Columbia, Canada. It is on the northeastern edge of the Tencho Glacier and represents several different styles of volcanic activity on the Mount Edziza complex. It is in the Northern Cordilleran Volcanic Province and last erupted during the Pleistocene period.
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.
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.
Castle Rock is a volcanic plug located 13 km (8 mi) west of Iskut and 8 km (5 mi) northwest of Tuktsayda Mountain in British Columbia, Canada. Castle Rock is part of the Pacific Ring of Fire that includes over 160 active volcanoes and is in the Klastline Group of the Northern Cordilleran Volcanic Province and last erupted in the Pleistocene.
Armadillo Peak is a 7.5-million-year-old caldera, located about 3 km north of Bourgeaux Creek and northeast of Raspberry Pass, British Columbia, Canada. It is south of Mount Edziza and is overlapped by the Ice Peak central volcano, which was formed during the early Pleistocene. Its caldera is largely destroyed by glaciers. It is part of the Mount Edziza volcanic complex, which is made of basaltic lava flows.
Nahta Cone is a cinder cone in northern British Columbia, Canada, located 69 km (43 mi) southwest of Tatogga, 9 km (6 mi) north of Wetalth Ridge and south of Telegraph Creek. It lies in the southwestern corner of Mount Edziza Provincial Park.
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.
Tadeda Peak, also known unofficially as Tadeda Centre, is a volcanic peak in northern British Columbia, Canada, located just northeast of Raspberry Pass in Mount Edziza Provincial Park.
IGC Centre is a lava dome in Mount Edziza Provincial Park of northern British Columbia, Canada. It is thought to have formed and last erupted during the Miocene period.
Sezill Volcano is a lava dome in Mount Edziza Provincial Park of northern British Columbia, Canada. It is thought to have formed and last erupted during the Miocene period. The volcano gets its name from being adjacent to Sezill Creek.
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 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 Finlay tephras are two tephra deposits in northern British Columbia, Canada. They take their name from the Finley River and were deposited just before 10,220–10,560 years ago. The source for the two tephra deposits is unknown but were likely erupted during two closely spaced periods of volcanism at one or two volcanoes associated with the Northern Cordilleran Volcanic Province. Volcanoes suggested to have erupted the tephras include Hoodoo Mountain, Heart Peaks, the Mount Edziza volcanic complex and Level Mountain.
