The white cement disk has been replaced in 25 feet of water in the lake below the Sinnott Memorial to aid the visitors to appreciate and grasp the extreme clarity and deep blue color of the water. One of the binoculars at Sinnott Memorial is trained upon the 24 inch object. Paul Herron, boatman for the Park Company, lifted the disc from its old location, repainted it, and then reinstalled it. Metal legs were attached to one edge so that the disc tilts toward the observation center.
