Mt. Garibaldi
Mount Garibaldi is a potentially active stratovolcano in the Sea to Sky County of British Columbia, 50mi north of Vancouver, Canada. This volcano is located in the southernmost Coast Mountains. Also 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.
Mount Garibaldi takes up the southwest corner of Garibaldi Provincial Park overlooking the town of Squamish. It is the only volcano in North America known to have been formed upon a glacier. It is not considered part of the Cascade Range. The height of Mount Garibaldi is 8,796’ (2,678m).
If Mount Garibaldi were to erupt, the town of whistler and Squamish would be in danger, but it hasn’t erupted in a very long time. The last eruption was in 8051 BC. Mount Garibaldi began erupting about 250,000 years ago and has grown steadily since then. Like most of the Cascade volcanoes, it has its own origins in the Cascadia subduction zone; a long convergent plate boundary that stretches from mid- Vancouver Island to Northern California. The first European to see the mountain in 1792, Captain George Vancouver, traded with the local natives in the area. When skiing became popular in the 1940s, Vancouver skiers began to search the glaciers and rugged mountains within the park. Eventually in the year of 1944, a club of skiers completed the first ever ski of Mt. Garibaldi.
Mount Garibaldi contains three main named peaks. The highest of course is the mountain itself, the second highest is Atwell Peak at the southern edge of the summit plateau, and the lowest of the three is the rounder Dalton Dome west of the highest summit. Two glaciers lie right below the east side of Atwell Peak. Straight north from Atwell toward the mountain lays a small, high-elevation ice cap called the Cheekye Glacier. (Cheekye River)
