Mount Jimmy Jimmy is a 2208m (7,244feet) glaciated mountain located in the Coast Mountains in southwestern British Columbia, Canada. It is situated northwest of Squamish, and 100NaN0 northwest of Ossa Mountain, which is its nearest higher peak. Mt. Jimmy Jimmy is the highest point of the Tzoonie-Clowhom Divide.[2] Precipitation runoff from the peak and meltwater from its immense glaciers drains into tributaries of the Squamish River and Clowhom River. The mountain was named for Chief Jimmy Jimmy (native name Swahsh), a leader of the Squamish Nation, who had traplines in the vicinity of the mountain and was a skilled paddler.[1] [3] The mountain's name was officially adopted on June 6, 1957, by the Geographical Names Board of Canada.[4]
Based on the Köppen climate classification, Mount Jimmy Jimmy is located in the marine west coast climate zone of western North America.[5] Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (Orographic lift), causing them to drop their moisture in the form of rain or snowfall. As a result, the Coast Mountains experience high precipitation, especially during the winter months in the form of snowfall. Temperatures can drop below −20 °C with wind chill factors below −30 °C. July through September offer the best months to catch favorable weather for climbing Mount Jimmy Jimmy.
