Swiss couloir

We went up the Swiss couloir today we left hermit parking around 7:00. We were going up the couloir around 12 o'clock and back for 3 oclock. No sign of instability during our ascent. We bootpack up the couloir we stop just before the top. There was a thick crust down 10 cm close from the top and so we decided not to go further. On our way down lizard tail there was lots of debris from the last days. Snow was very wet and big snowballs were rolling down next to us as we were ski down. I would recommend to start earlier if you are planning to go around there soon :)
