The City of Menlo Park provided me with photos that were taken when the sculpture was erected over 25 years ago. I scanned the photos and the drawings from the brochure that got me interested in the sculpture in the first place when I found it on the ground at Bedwell Bayfront Park. This gives you an impression of the 53 stations along the path. Have a look at the trees in picture 52 to get a feeling for the size of the sculpture.
I will put in a post with a sign that shows the drawing at each of the 53 rock clusters to enable visitors to understand the meaning of the rocks.
