Mount McKinley, Solo of the Cassin Route. Charlie Porter made a remarkable solo ascent of the Cassin route on the south face of McKinley. He is reported to have been in the area for two weeks and four days on the final climb. He is said to have taken only 36 hours in a single push from the top of the Japanese Couloir. With his usual reticence, Porter has given us no details.
