From Highway #40 there are striking similarities between Mount Indefatigable and Mount Invincible. They have similar profiles across their summits and their eastern slopes are steep near the summit ridges. The less steep slopes below these cliffs hold snow in a similar manner and this highlighting indicates that the layers of rock are oriented in the same manner. Both mountains are 2670 metres in elevation.
These similarities must have been noticed by members of the Boundary Commission who named them after two warships which came to similar ends during the Battle of Jutland. HMS Indefatigable was part of the Second Battle Cruiser Squadron. Struck by five shells from the German Battleship Vonder Tann, it exploded and only two of the 1015 crewmembers aboard survived. HMS Invincible was Admiral Hood's flagship as he led the Third Battle Cruiser Squadron into the battle. Initially Hood's ships were successful in landing some heavy blows on enemy ships but then his flagship was destroyed by enemy gunfire with the loss of 1026 men.
A 1964 report by the Geological Survey of Canada referred to deposits of gypsum on the slopes of Mount Indefatigable and led to the building of a road along the northern slopes of the mountain to a mine site near the summit. However the deposit proved to be of low quality and only one load of gypsum was taken out.
When Walter Wilcox visited the area in 1901, he took time to complete the first ascent of Mount Indefatigable, likely realizing that its summit would provide a splendid viewpoint of the Kananaskis Lakes and surrounding peaks.
