Routes in Black Mountain Bouldering for selected grade

Sit start with a high heel hook and fingers in the small notch, push for the shelf and go from there to rock over your heel

Sit start then head left around the arete on small holds and incuts. The crux is getting up over the ledge at mid height. Roughly v3 if you eliminate a few holds.

Difficult to grade. From a standing start, use the lovely hand-grip at shoulder height, place your feet at either side as high as you can get them, and dyno to the second ledge above your head - that is, the higher one. While it takes some strength to accomplish, much more of the climb is about trusting you can do it and won't body-slam the rock.

Stand start. Up the right side of the boulder using the crimp then trending left to a rail and up.

As for 12, get set on your feet using the crimp then head left around the corner using the rail to steady yourself and up from there.

Sit start underneath the rooflet, then climb up the arete, hugging both sides and top out.
