SE ridge, with Lyskamm on the left. There was a keen cold NE wind, but good sunny shelter among some rocks just below the summit, where I spent a pleasant half hour before wandering along to the SE top and back. 8.40am, 21/08/13
Castor N ridge again, with the W side of Dom, Täschhorn and Alphubel; Rimpfischhorn far right. 8.55am, 21/08/13
I start a reluctant descent - Castor was very enjoyable! 9am, 21/08/13
