Went out with Steve today to have a look at Tryfan. I must say the most difficult part of the day was the condition of the snow - it was very much one step up and 2 or 3 steps down. The snow was very unconsolidated with no base. We think we managed to squeeze a new route between Green Gully and Deffing out the Ben which was about grade 5 up to the point were we had to retreat due to a lack of time (the condition of the snow was really time consuming) but it looked like we would have finished up Green Gully anyway. I think we'll wait for better conditions before returning. A good day out though.
