Notes

  1. The relationship of the Silverthrone complex with other volcanoes in the Cascade Volcanic Arc is not clear and remains uncertain.[1] However, it is still considered to be a member of the Garibaldi Volcanic Belt, the Canadian portion of the Cascade Volcanic Arc formed by subduction of the Juan de Fuca Plate.[1][2]
  2. Like Silverthrone, the relationship of the Franklin Glacier Complex with other volcanoes in the Cascade Volcanic Arc is not clear and remains uncertain.[3] But it is still considered to be a member of the Garibaldi Volcanic Belt, the Canadian portion of the Cascade Volcanic Arc formed by subduction of the Juan de Fuca Plate.[2][3]
