Mount Garibaldi, rising above scenic Garibaldi Lake to the north, is a largely Pleistocene stratovolcano capped by a lava dome complex. The volcano was partially constructed over the Cordilleran ice sheet and displays many ice-contact features. Its final eruptions during the early Holocene included the emission of lava flows that mantled the west-side landside headwall and a massive lava flow from Opal Cone, a SE flank vent, that traveled 20 km to the south and west.
