Hexahedron

Start down low on the corner (highest point) of the boulder with your feet underneath the small roof and around the right side. Move up to a decent edge with your left hand, then the same with your right. Bring your feet over the edge and stand up to top out on good holds.

Directly behind the Diamond boulder, situated on the only corner of the boulder that has any bouldering potential and also happens to be the highest point.
