When you reach a wide spot in the road that was once a log landing, turn off the road and onto the old log skidding trail. Follow it until it peters out, then make your way on up to the summit. Note that Pt. 7740 was on your right the entire time you've been on the dirt road and so you could have cut up through the forest at any point. This route is just a little easier as there are fewer downed logs and other obstacles along the way.
