Tuya volcanic field

The Tuya volcanic field is a cluster of volcanoes in far northern British Columbia near the Yukon border, centered on the Tuya Range within the Cassiar Mountains, with some vents extending onto the Kawdy Plateau. It is especially notable for its tuyas, steep-sided, flat-topped volcanoes formed when lava erupts beneath ice. The field also includes small shield volcanoes, postglacial lapilli cones, and lava flows, showing activity during and after glaciation. Gabrielse Cone and the West Tuya lava field are the only identified nonglacial volcanoes. Together, these landforms make the area one of Canada’s notable glaciovolcanic landscapes.
