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]
