The Mount Cayley volcanic field is a north–south trending volcanic zone
on the coast of British Columbia that stretches 31 km (19 mi) from the
Pemberton Icefield to the Squamish River. The field is located in the
Sea-to-Sky Corridor of southwestern British Columbia, Canada. It forms
the central segment of the Garibaldi Volcanic Belt, the Canadian
portion of the Cascade Volcanic Arc, which extends from Northern
California. Most of the Cayley 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. The field gets its name from Mount Cayley, the largest
and most persistent volcano, 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. Eruptions along the length of
the field began between 1.6 and 5.3 million years ago. At least
23 eruptions have occurred throughout its eruptive history. This
volcanic activity ranged from effusive to explosive, with magma
compositions ranging from basaltic to rhyolitic.
