This is the boulder problem hidden away in a cave just above the main parking lot. Start sitting way back in the cave and crimp your way to the large underclings 3/4 of the way out. Match the last undercling and use a tiny crimp intermediate to throw big for the lip of the cave, then keep tight and work up to the obvious finishing 'spike.' Unfortunately several holds have broken over the past few years and some of the moves (particularly at the start) aren't as nice as they used to be. Still a great endurance boulder problem, though - something like 18 moves long and horizontal the whole way.
From the kiosk at the main parking lot, look up and left. You'll see a small looking cave. Now take the trail to your left that leads up towards the Holderness Corner. About 3/4's of the way up, you'll see a faint trail that trends down and right. This trail will get you to the cave & to the boulder problem.
