Jumbo Mountain, sometimes called Mount Jumbo, is a 3,437 meter (11,276 ft) elevation mountain summit located 42 km (26 mi) west-southwest of Invermere in the Purcell Mountains of southeast British Columbia, Canada.[3][4] The nearest higher peak is Mount Farnham, 11 km (6.8 mi) to the north-northeast, and Karnak Mountain is set 0.79 km (0.49 mi) to the west.[4] Jumbo and Karnak form a double summit massif which is the second-highest mountain in the Purcells, and fourth-highest in the Columbia Mountains.[4] The first ascent of Jumbo Mountain was made August 4, 1915, by H.O. Frind, A.H. & E.L. MacCarthy, M & W.E. Stone, B. Shultz, and Conrad Kain via the North/Northeast Slopes.[1] March 5, 1919, Conrad made a solo ascent of Jumbo Mtn on snowshoes - credited as the first winter ascent of an 11,000-ft peak in Canada. [5] The peak was named by Edward Warren Harnden after the 1892 Jumbo Mineral Claim on nearby Toby Creek, which in turn was named for Jumbo the elephant.[1] The mountain's toponym was officially adopted March 31, 1924, when approved by the Geographical Names Board of Canada.
Based on the Köppen climate classification, Jumbo Mountain is located in a subarctic climate zone with cold, snowy winters, and mild summers.[6] Winter temperatures can drop below −20 °C with wind chill factors below −30 °C. Precipitation runoff from the mountain drains into south into Jumbo Creek which is a tributary of Toby Creek, and meltwater from the Jumbo Glacier on its north slope drains into Horsethief Creek which, like Toby Creek, is also a tributary of the Columbia River.
