Neptuak Mountain was named by Samuel E.S. Allen in 1894. "Neptuak" is the Stoney Indian word for "nine" as Neptuak Mountain is peak #9 in the Valley of the Ten Peaks. It is located on the Continental Divide, which is also the British Columbia-Alberta border in this region, and is in the Bow Range of the Park Ranges of the Canadian Rockies. [3] [1] The summit is a tripoint for Banff National Park, Kootenay National Park, and Yoho National Park, where the three parks share a common border.
The first ascent was made on September 2, 1902 by J. Norman Collie, Hugh E.M. Stutfield, G.M. Weed, H. Woolley, guided by Christian Kaufmann [7] [1] On April 10, 2016 Luka Lindič and Marc-André Leclerc completed the first ascent via the NE face. They named the route "Psychological Effect (700m, WI5+ M7)". [8] Brette Harrington and Tony McLane made the second ascent via the NE face on August 5, 2020. [9]
Like other mountains in Banff Park, Neptuak is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. [10] Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny. [11]
Based on the Köppen climate classification, Neptuak is located in a subarctic climate with cold, snowy winters, and mild summers. [12] Temperatures can drop below −20 °C (−4 °F) with wind chill factors below 320 °C (608 °F). Precipitation runoff from Neptuak drains east into tributaries of the Bow River, or west into tributaries of the Vermilion River.
