Mount Garibaldi
Mount Garibaldi is a potentially active stratovolcano in the Sea to Sky Country of British Columbia, 80 km (50 mi) north of Vancouver, British Columbia, Canada. Located in the southernmost Coast Mountains, it is one of the most recognized peaks in the South Coast region, as well as British Columbia's best known volcano. It lies within the Garibaldi Ranges of the Pacific Ranges.This heavily eroded dome complex occupies the southwest corner of Garibaldi Provincial Park overlooking the town of Squamish. It is the only major Pleistocene age volcano in North America known to have formed upon a glacier. Although part of the Garibaldi Volcanic Belt within the Cascade Volcanic Arc, it is not considered part of the Cascade Range.
