Start half-sitting on the very large crimps, and move up to the crimp right below the odd-colored, spherical rock jutting out of the wall. Bring a foot up to the good, obvious foothold, and at this point you can either make a couple of small, difficult crimp moves to get to the next high, good crimp, or just try one large, reach-y move. Once you've done those, just make the average top-out. Remember - only the face of the wall is on, don't cheat by using any of the adjacent rock.
By the Space Boulder, find the dark, "cave-like" hole. Drop down into this hole and face the trail, and you'll be facing Sub-Commander T'pol. It should be obvious once you've found the hole. If you top-out right by the trail, you've done it right.
