The Tower of Babel is a conspicuous quartzite monolith at the northern end of the mountain, and is apparent to park visitors at Moraine Lake. It was named in 1899 by Walter D. Wilcox because its profile reminded him of the biblical Tower of Babel. The first ascent of the tower was made in 1959 by G. Boles, B. Greenwood, and A. Washington. Mount Babel acquired its name from its outlier tower that rises above Moraine Lake.
