After a night of heavy rain but with an improving forecast Chris and I headed up into the Ogwen Valley to have a look at a couple of scrambles on Tryfan. We splashed up to the west face and made an ascent of the Wrinkled Tower. This is a great grade 3 scramble which bring you out on the north ridge just above the Cannon Stone and deserves to be far more popular. We avoided the crux, a greasy chimney and exposed traverse by straight forward grass slopes to the left. Once on the north ridge we made a quick ascent to the summit in strengthening winds and driving rain, descending by the quick and easy West Gully. Chris then headed off to Plas Y Brenin to make full use of their drying facilities and make his final preparations for his MIA assessment. Through the next five days he'll be assessed on his personal climbing, rescue skills, short roping, teaching and navigation. Good luck to everyone on the assessment and hope the weather improves.
