Neptuak Mountain



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. The summit is a tripoint for Banff National Park, Kootenay National Park, and Yoho National Park, where the three parks share a common border.

Geology
Like other mountains in Banff Park, Neptuak is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny.

Climate
Based on the Köppen climate classification, Neptuak is located in a subarctic climate with cold, snowy winters, and mild summers. Temperatures can drop below −20 C with wind chill factors below −30 C. Precipitation runoff from Neptuak drains east into tributaries of the Bow River, or west into tributaries of the Vermilion River.
