Bell-Irving volcanic district
The Bell-Irving volcanic district is a volcanic field in the upper Bell-Irving River watershed of northern British Columbia, Canada. It is considered part of the Northern Cordilleran Volcanic Province, consisting of 14 volcanic centres. They comprise pillow lava and/or volcaniclastic rocks, which were possibly emplaced by alpine glaciovolcanic eruptions during the Pleistocene. The volcanic deposits were discovered between 1992 and 2004 but remained undescribed until 2006.[1]
