'''Mount Indefatigable''' is a {{Convert|2670|m|ft|abbr=off|adj=on}} mountain summit located in Peter Lougheed Provincial Park in the Canadian Rockies of Alberta, Canada.<ref name=GemTrekKL/> The peak is visible from Alberta Highway 40, and the Kananaskis Lakes area. Mount Indefatigable's nearest higher neighbour is Mount Invincible, {{convert|1.8|km|mi|abbr=on}} to the northwest.<ref name=bivouac/>

Like so many of the mountains in Kananaskis Country, Mount Indefatigable received its name from the persons and ships involved in the 1916 Battle of Jutland, the only major sea battle of the First World War.<ref>{{cite web|url=https://albertashistoricplaces.wordpress.com/2016/06/22/the-battle-of-jutland-first-world-war-commemoration-and-alberta-place-names/|title=The Battle of Jutland|publisher=Alberta Historic Places|access-date=2025-05-03}}</ref>

==History== Mount Indefatigable was named in 1917 for {{HMS|Indefatigable|1909|6}}, a British battlecruiser that sank during the Battle of Jutland in World War I.<ref name="crdb"/><ref>{{cite book|title=Place-names of Alberta|year=1928|publisher=Geographic Board of Canada|location=Ottawa|page=67|url=https://babel.hathitrust.org/cgi/pt?id=mdp.39015070267029&view=1up&seq=71}}</ref> The mountain's toponym was officially adopted in 1922 by the Geographical Names Board of Canada.<ref name=cgndb/>

The first ascent of the peak was made in 1901 by Walter D. Wilcox.<ref name="crdb"/><ref name=bivouac/>

In 2005, the popular trail to the summit of Mount Indefatigable was decommissioned to protect prime grizzly bear habitat. Though the unmaintained trail still exists, travel is discouraged by Alberta Parks.<ref>{{cite web |title=Why you shouldn't go up the Mt.

==Geology== Mount Indefatigable 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.<ref name=gadd>{{citation|title=Geology of the Rocky Mountains and Columbias |author=Gadd, Ben |year=2008}}</ref>

==Climate== Based on the Köppen climate classification, Mount Indefatigable is located in a subarctic climate zone with cold, snowy winters, and mild summers.<ref name=Peel>{{cite journal | author = Peel, M.
