The Northern Cordilleran Volcanic Province (NCVP), formerly known as the Stikine Volcanic Belt, is a geologic province defined by the occurrence of Miocene to Holocene volcanoes in the Pacific Northwest of North America. This belt of volcanoes extends roughly north-northwest from northwestern British Columbia and the Alaska Panhandle through Yukon to the Southeast Fairbanks Census Area of far eastern Alaska, in a corridor hundreds of kilometres wide. It is the most recently defined volcanic province in the Western Cordillera. It has formed due to extensional cracking of the North American continent—similar to other on-land extensional volcanic zones, including the Basin and Range Province and the East African Rift. Although taking its name from the Western Cordillera, this term is a geologic grouping rather than a geographic one. The southmost part of the NCVP has more, and larger, volcanoes than does the rest of the NCVP; further north it is less clearly delineated, describing a large arch that sways westward through central Yukon.
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.
Kawdy Mountain is a subglacial mound on the Kawdy Plateau, the northernmost sub-plateau of the Stikine Plateau in northwestern British Columbia, Canada. It consists of nearly horizontal beds of basaltic lava, capping outward dipping beds of fragmental volcanic rocks and last erupted in Pleistocene. Kawdy Mountain is one of many basaltic volcanic features of the Stikine Volcanic Belt, which is forming because the North American tectonic plate is stretching slightly as it moves to the west.
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.
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.
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.
Dark Mountain, formerly also known as Black Mountain, is a mountain in the Tanzilla Plateau of the Northern Interior of British Columbia, Canada, located northeast of the settlement of Dease Lake, near Cry Lake.
Volcanism of Western Canada has produced lava flows, lava plateaus, lava domes, cinder cones, stratovolcanoes, shield volcanoes, greenstone belts, submarine volcanoes, calderas, diatremes and maars, along with examples of more less common volcanic forms such as tuyas and subglacial mounds.
Chikoida Mountain is a mountain on the Taku Plateau in northwestern British Columbia, Canada, located 52 km (32 mi) southeast of Atlin on the east side of the Silver Salmon River.
The Neck is a mountain in northwestern British Columbia, Canada, located in Mount Edziza Provincial Park. It is a volcanic feature of the Northern Cordilleran Volcanic Province that formed in the past 1.6 million years of the Pleistocene epoch.
Second Canyon Cone, also called Canyon Creek Cone is a cinder cone in the Boundary Ranges of the Coast Mountains in northwestern British Columbia, Canada. It is a volcanic feature of the Iskut-Unuk River Cones which is part of the Northern Cordilleran Volcanic Province and formed in the past 10,000 years of the Holocene epoch.
Round Mountain is a mountain in northwestern British Columbia, Canada, located 22 km (14 mi) east of Dease Lake.
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.
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.
Watson Lake Cone is a cinder cone in southern Yukon, Canada, located near the British Columbia-Yukon border. It formed and last erupted during the Pleistocene period and is part of the Northern Cordilleran Volcanic Province.
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.
