Photo Gallery

South Tuya, seen here from the north, is one of six subglacial volcanoes cluster close to Tuya Lake, in north-central British Columbia. The cone seen above comprises loose volcanic debris as well as dikes of basaltic rock intruded into the volcanic pile. The base of the volcano comprises pillow lavas and hyaloclastite, indicating that the volcano formed either beneath ice or with a large lake. Several small postglacial lapilli cones and lava flows have been reported in this area.
