This is a large sloper just to the right of the the #3 group. Have not done anything on this boulder yet but there may be at least one route. It's a sloper the entire way starting with some crimpers with just a friction top out. Top out will be a bit sketchy.
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 4 is the round sloper just to the right of the #3 group set into the side of the hill.
