From the Base of the spy, as for the East Ridge, walk north and then West up the North side of the rock. After about 30 meters you will pass a massive roof, some 10-15 feet off of the ground.

The top moves are the crux with moves on small holds just left of a left-leaning, left-facing open book corner.
A few hand sized cams and a few stoppers.
