The Garibaldi Lake volcanic field is a volcanic field, located in British Columbia, Canada. It was formed by a group of nine small andesitic stratovolcanoes and basaltic andesite vents in the scenic Garibaldi Lake area immediately north of Mount Garibaldi during the late Pleistocene and early Holocene.[1] The oldest stratovolcano, The Black Tusk, formed between about 1.3 and 1.1 million years ago (Ma). Following glacial dissection, renewed volcanism produced the lava dome and flow forming its summit. Other Pleistocene vents are located along and to the west of the Cheakamus River. Cinder Cone, to the east of The Black Tusk, produced a 9-km-long lava flow during the late Pleistocene or early Holocene.
Mount Price, west of Garibaldi Lake, 5 km (3.1 mi) south of The Black Tusk, was formed in three stages of activity, dating back 1.1 million years, the latest of which produced two large lava flows from Clinker Peak during the early Holocene that ponded against the retreating continental ice sheet and formed The Barrier, containing Garibaldi Lake.
The Table is a steep-sided andesite tuya, situated approximately 3 km southwest of Mount Price and south of Garibaldi Lake. It rises 305 meters above glaciated basement rocks. The tuya formed by effusion of flatlying flows within erratics on its summit and lack of erosional features attributable to glacial suggest that The Table was also formed during the early Holocene.
Clinker Peak is a stratovolcano on the west shoulder of Mount Price on the west side of Garibaldi Lake. It has produced two large lava flows about 9,000 years ago.
Mount Brew is a subglacial mound, which last erupted during the Pleistocene.
