Description Mt. Logan, 5957m, is the highest peak in Canada and rises nearly 4000m above the Seward glacier. The south face, shown here, hosts several major ridge lines descending from the summit plateau. Left of centre is the Hummingbird Ridge, which was first climbed in 1965 and has not been repeated, and to the right, in centre, is the Warbler Ridge, first climbed in 1977 and also never repeated.
