This climb starts 30-40 feet before La Cholla Jackson, and 20-30 feet before Chunky Monkey. Look for a large dihedral with a distinct knife-edge arete in the corner. Great Expectations begins on an east facing wall 3 climbs to the left of this arete. The picture included has this listed as #80.
The climbing starts by clipping a red homemade coldshut, and two other bolts before jumping around the arete on great holds (8). One should use long runners or unclip the second draw, and have your partner unclip the first to reduce rope drag. The climbing continues to a steep and juggy headwall with small roofs and long reaches. Good rests along with spectacular position and exposure makes this a great climb!!
Only way to make it 10c is to stay out of the corner. In one place, about where shown in the picture I think you will have to use the corner to avoid making it harder than rated. But if you use it too much, the route will seem soft. Go straight up to the anchors from the last bolt and you will be crimping and not downrating the climb.
