Mount Garibaldi (2678 m or 8786 ft) is a potentially active stratovolcano in Garibaldi Provincial Park, east of the Sea to Sky Highway (Route 99) between Squamish and Whistler, in the Coast Range, British Columbia, Canada. Below Mount Garibaldi are Table Mountain and Warren Glacier. Mount Garibaldi began erupting and growing steadily since 250,000 years ago and is the only major Pleistocene age volcano in North America known to have formed on top of a glacier. Although part of the Garibaldi Volcanic Belt within the Cascade Volcanic Arc, it is not considered part of the Cascade Range. The unusually-flat Table Mountain formed just 12,000 years ago from a lava eruption underneath a glacier! Regarding global warming and climate change: from the early 1700s to 2005, half (51%) of the glacial ice cover of Garibaldi Provincial Park melted away (reference: Koch et al. 2008, web.unbc.ca). The record of 1900s glacier fluctuations in Garibaldi Park is similar to that in southern Europe, South America, and New Zealand, suggesting a common, global climatic cause.
