This is the right most boulder and the farthest uphill of the #3 group. We have not climbed anything on this boulder yet. There seems to be a sketchy overhung route on the small face facing the river. Because of the slope of the ground below it does not look like an easy place to fall.
Follow the gravel road from the Hitchiti parking lot. You could also follow the hiking trail but the road is shorter. When you get down to the river go right along the river (north) until you see the boulders. Boulder 3B is the boulder farthest to the right and farthest up the hill. This group of boulders is at the bottom of the hill closest to the river.
