I climbed the North Face of Mount Church with my brother when we traversed from Borah in early August 2007. The face was snow free. Don't get me wrong. It was a lot of fun, but I felt it was dangerous. We roped up for the last 300 feet because there was loose rock all over the slab and a distinct possibility of getting beaned. The rock is not steep and has high friction, but without a rope you can fall a long way if you get hit by a rock or somehow screw things up. Our route featured a few rock bands about 5 feet high that traversed the slabs and needed to be climbed. Those were where we needed to pay special attention because the rock bands were lower 5th class, vertical, and loose. I suggest a short light rope, 6 wire nuts and 6 slings. A problem is that the rope itself can easily knock rocks loose. Wear a helmet (we did not and regretted it).
Look closely at this picture. Note the loose rock everywhere.
