A subaqueous volcano is a volcano formed beneath water (similar to submarine volcanoes) and never builds above lake level. They are commonly in the form of gently sloping tuff cones, although they can sometimes have an unvolcano-like form, such as White Horse Bluff in the Wells Gray-Clearwater volcanic field of east-central British Columbia, Canada.
