Kaina Mountain is a 9,494-foot peak in Glacier National Park’s Lewis Range, in the park’s northeastern section just north of Kaina Lake. Like many mountains in Glacier, it is made of sedimentary rock laid down from the Precambrian to the Jurassic in ancient shallow seas. Its broader geologic setting was transformed beginning about 170 million years ago, when the Lewis Overthrust fault drove a massive slab of older Precambrian rock over younger Cretaceous rock. The mountain stands in an alpine subarctic climate marked by long, cold, snowy winters, short cool-to-warm summers, and extreme winter temperatures and wind chill.
