Opal Cone is a cinder cone located on the southeast flank of Mount Garibaldi in the Coast Mountains of British Columbia, Canada. It is the source of a 15 km long broad dacite lava flow with prominent wrinkled ridges. The lava flow is unusually long for a silicic lava flow.
Opal Cone is a member of the Cascade Volcanoes, but it is located in the Garibaldi Ranges in the Coast Mountains and not in the Cascade Range proper.
