Whistler Mountain is a mountain in the Fitzsimmons Range of the Pacific Ranges of the Coast Mountains, located on the northwestern edge of Garibaldi Provincial Park. It is the location of the Whistler-Blackcomb ski resort and the town of Whistler, British Columbia, Canada, and played host to the 2010 Winter Olympics. Previously, the mountain was called "London Mountain," named after a mining claim in the area and the fog at the mountain's base.
