The Northern Cordilleran Volcanic Province has been a zone of active volcanism since it began to form 20 million years ago. Unlike other parts of the Pacific Ring of Fire, the Northern Cordilleran Volcanic Province has its origins in continental rifting—an area where the Earth's crust and lithosphere is being pulled apart.

Lava fountains can occur in the Northern Cordilleran Volcanic Province roughly every 100 years. [10] Level Mountain, the largest volcano of the Northern Cordilleran Volcanic Province. The large brown area in the middle is a dissected stratovolcano and the surrounding light brown is the broad shield volcano comprising a lava plateau.

Tseax Cone is one of the southernmost volcanoes in the Northern Cordilleran Volcanic Province. [10] This is a broad area of shield volcanoes , lava domes , cinder cones and stratovolcanoes extending from northwestern British Columbia northwards through Yukon into easternmost Alaska . [ 27 ]
Over half of the Northern Cordilleran volcanoes are located in northwestern British Columbia. This portion is where the most recent eruptions in Canada and of the Northern Cordilleran Volcanic Province have occurred, including the catastrophic 18th century eruption of Tseax Cone and the 1904 eruption of The Volcano.

Cracker Creek Cone is a small cinder cone in northwestern British Columbia.A large lava flow that partly filled Ruby Creek may have originated from this cone. The lower west side of the cone appears to be partly covered by glacial till suggesting that the cone is older than the most recent glacial advances down Ruby Creek.
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. [1] Volcanoes suggested to have erupted the tephras include Hoodoo Mountain, Heart Peaks, the Mount Edziza volcanic complex and Level ...
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.
