Northern Cordilleran volcanic province
From Wikipedia, the free encyclopedia
The northern Cordilleran volcanic province (NCVP) comprises volcanoes that are 10 million years old or younger in northern British Columbia, the Yukon, and easternmost Alaska. The Stikine Volcanic Belt is used to refer to a subset of these volcanoes located near the Stikine River, in northwestern BC. The province contains more than 100 volcanoes, including Alligator Lake, Heart Peak, Hoodoo Mountain, Lava Fork, Mount Edziza, Ruby Mountain, Tseax Cone and Volcano Mountain.
The southern-most extent of the NCVP is near the Tseax River cone, a few dozen kilometers north of Terrace, BC, and the northwestern most extend includes Prindle volcano, in eastern Alaska. The Tseax River cone, and a series of lava flows immediately northwest along Lava Fork Creek, probably represent the most recent volcanic activity in Canada (100-300 years ago).
The volcanoes are the result of the interaction between the Pacific Ocean tectonic plate and the North American plate.
