This is a finger to wide hand crack that starts at the far end of the upper wall. In an old guide book the author said "your sole reason for existance as a climber is to do this climb". I agree.
The crack starts with finger locks for the first 50' or so then after a fingery traverse with slopey feet the crack widens to hands with a fist or two thrown in for good measure till you reach the top. Classic!
far end of the main climbing wall in the quarry.
Single rack including many stoppers through a #3 camalot
