**Mount Ball** is a [mountain](/source/Mountain) located on the [Continental Divide](/source/Continental_Divide_of_the_Americas), on the borders of [Banff](/source/Banff_National_Park) and [Kootenay](/source/Kootenay_National_Park) national parks in Western [Canada](/source/Canada). Mt. Ball is the highest peak of the [Ball Range](/source/Ball_Range) in the [Canadian Rockies](/source/Canadian_Rockies).

The mountain was named in 1858 by [James Hector](/source/James_Hector) after [John Ball](/source/John_Ball_(naturalist)), a politician who helped secure funding for the [Palliser expedition](/source/Palliser_expedition).[5][6] The name was officially adopted in 1924 based on [Palliser's](/source/John_Palliser) 1863 map of British North America.[7]

Mt. Ball can be ascended from a [scrambling](/source/Scrambling) route by late summer but involves remote bushwhacking, which limits the number of attempts per year. The trailhead is located at the Marble Canyon Campground in Kootenay National Park.[4]

## Geology

Mount Ball is composed of [sedimentary rock](/source/Sedimentary_rock) laid down during the [Precambrian](/source/Precambrian) to [Jurassic](/source/Jurassic) periods. Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the [Laramide orogeny](/source/Laramide_orogeny).[8]

## Climate

Based on the [Köppen climate classification](/source/K%C3%B6ppen_climate_classification), Mount Ball is located in a [subarctic climate](/source/Subarctic_climate) zone with cold, snowy winters, and mild summers.[9] Winter temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports glaciers on its slopes. Precipitation [runoff](/source/Surface_runoff) from the east slope drains to the [Bow River](/source/Bow_River) via Redearth Creek, and the west slope drains into tributaries of the [Vermilion River](/source/Vermilion_River_(British_Columbia)).
