It has been partly glaciated and Ar-Ar geochronology shows that is it about 730,000 years old. It mainly comprises palagonitized tephra ([[tuff]], [[lapilli tuff]], [[tuff breccia]]) but also has a few dykes and jointed lava flows on its flanks. The top still has flat-lying lava flows erupted after the tephra pile grew above the surface of the enclosing lake. The other volcanoes in the area include [[Tuya Butte]], [[South Tuya]] and [[Ash Mountain (British Columbia)|Ash Mountain]]. The [[volcano]]es in the region form part of the [[Northern Cordilleran Volcanic Province]].
