THE SUMMIT OF THE MATTERHORN IS A RIDGE-HOLE It was a cornice of snow the day of our ascent. Note the dominance, and how steep are the rocks between the shoulder (the white patch on the left ridge) and the top. The ropes are there (see page 663). The Obergabelhorn (right)shows the difference between the north side of a mountain which is snow-covered-unless too steep-and its bare southern side (see also 648). Dotted lines indicate our route up the Wellenkuffe (see page 647), whose snow-cap is always recognizable from the Trift Glacier, with very little snow. Photo by G. P. Abrahams.
