Le champ volcanique du mont Cayley se trouve sur la côte de la Colombie-Britannique dans l'ouest du Canada qui s'étend sur 31 kilomètres du champ de glace de Pemberton au fleuve Squamish. Ce champ volcanique constitue le segment central de la ceinture volcanique de Garibaldi, la partie canadienne de l'arc volcanique des Cascades. Il tire son nom du mont Cayley, le volcan le plus grand et le plus persistant, situé à l'extrémité sud du champ de glace Powder Mountain.

[en] Mount Cayley volcanic field

The Mount Cayley volcanic field (MCVF) is a remote volcanic zone on the South Coast of British Columbia, Canada, stretching 31 km (19 mi) from the Pemberton Icefield to the Squamish River. It forms a segment of the Garibaldi Volcanic Belt, the Canadian portion of the Cascade Volcanic Arc, which extends from Northern California to southwestern British Columbia. Most of the MCVF volcanoes were formed during periods of volcanism under sheets of glacial ice throughout the last glacial period. These subglacial eruptions formed steep, flat-topped volcanoes and subglacial lava domes, most of which have been entirely exposed by deglaciation. However, at least two volcanoes predate the last glacial period and both are highly eroded. The field gets its name from Mount Cayley, a volcanic peak located at the southern end of the Powder Mountain Icefield. This icefield covers much of the central portion of the volcanic field and is one of the several glacial fields in the Pacific Ranges of the Coast Mountains.
