From Wikipedia, the free encyclopedia
Tuya Butte is one of the tuyas, located in the Tuya Volcanic Field in north-central British Columbia. The base of the volcano comprises pillow lavas and hyaloclastite, indicating that the volcano formed either beneath ice or with a large lake. The volcano has no summit crater or obvious vent, which is suggesting that the volcano might have been fed by a fissure, although several indications suggest a vent location near a large cirque on the north face. Some of the other volcanoes in the area include South Tuya, Ash Mountain, and Mathews Tuya.
