Crenellation

Crenellation ascends the tall, striking arête on The Keep's southeast corner. Sit start with sidepulls on each side of the arête and make easy moves to the shelf at half height. Pull a committing, more-funky-than-hard move to get your feet up on the shelf using sidepulls around the arête. Continue directly up the arête to the pointy, positive lip and good top out holds. Excellent position throughout. 

The obvious, tall arête you'll see when you first arrive at the area on the SE corner of the boulder. 

A handful of pads. A large dead tree used to prevent adequate paddage but its removal now makes for a flat landing.
