|(05) The Open Face Wall
This crack isn't very diverting for an experienced climber, as it's very low-angle on HUGE face holds (no jamming required). But it's perfect for a first trad lead. The rock is good for Mentmore, being varnished inside the crack, there are endless hands-free stances to fiddle nuts into the crack, and it's short. Run it out or sew it up, whatever you feel comfortable with.
The obvious, right-leaning crack that splits the Open Face Wall from top to bottom.
A small selection of trad gear up to about 2 inches ought to be fine. There is a 2-bolt anchor at the top.
