This knocker can be hard to find. It’s two roads up from Millionaires’ Row and to the south, but its bay-facing side is obscured by trees. I took this photo in 2003; today I could barely see it from the road, and I knew where to look. It’s mostly chert. I’m calling it the high knocker because it’s the tallest one in the cemetery; at least two others are higher on the hill.
If you approach this rock, beware of poison oak.
