South Twin

South Twin is a mountain peak in Jasper National Park that rises above 3,500 meters elevation. It forms part of a distinct double summit with North Twin at the northeastern edge of the Columbia Icefield.

Early mountaineers explored the area around 1898 and created the first detailed maps of this double summit. The name South Twin was officially established to distinguish between the two closely spaced peaks.

Fred V. Field and Edward Feuz Jr completed the first recorded ascent of South Twin on July 8, 1924, establishing a route through the challenging terrain.

The climb requires experience in ice climbing and glacier travel, as the route crosses frozen terrain and technical sections. Visitors should expect demanding physical conditions and should plan for stable weather to successfully reach the summit.

The mountain ranks as the ninth highest peak in the Canadian Rockies, featuring a connecting ridge to North Twin that requires technical ice climbing skills.
