Other than a vertical abseil, the ridge is the only way down to the glacial plateau, about 200 feet below. It's frequently swept by high winds, blizzards, and has no hand rail. A fall to the right culminates in a few minor crevasses after perhaps 150 feet. A slide to the left lasts only about 30 feet, before you go over the edge - after which your fall would be uninterrupted for thousands. I found the descent of the ridge to be a novel but highly effective means of waking up.
