Ash Mountain is a tuya in northcentral British Columbia, located immediately north of High Tuya Lake. It is one of the six tuyas clustered close to Tuya Lake. The base of the volcano comprises pillow lava and hyaloclastite indicating that the volcano formed beneath ice or under a large lake. The volcano comprises loose debris as well as dikes of basaltic rock that intruded into the volcanic pile. Other tuyas in the area include Tuya Butte, South Tuya and Mathews Tuya, although most of the group of tuyas are un-named. Ash Mountain is the highest tuya in the Tuya Range.
