Climbing up to the Sefinenfurke pass, between Griesalp and Murren, Patricia stopped while I took this picture.  You can see the cable and the "ladder".  It was very steep and, after about 4 hours of going up and up, it was a difficult way to finish the "up" part of the the hike.  But the view of the Jungfrau from the top, just above us in this picture was spectacular and worth the effort.
