Mount Babel takes its name from the much lower "Tower of Babel," the top of which is over 700 metres below the summit of Mount Babel. Walter Wilcox named the Tower of Babel after it reminded him of the story in the bible in which the Tower of Babel reached to the heavens. It was a huge rockfall from the Tower of Babel which formed the dam which holds back Moraine Lake.Walter Wilcox had thought when he named the lake that the rocks were carried forward by an advance of the glacier in the valley and left as a terminal moraine.
