Conceived by environmental artist Peter Richards and fashioned by master stonecutter George Gonzales, this unusual wave-activated acoustic sculpture gives off subtle harmonic sounds produced by seawater as it passes through 25 tubes. The sound is loudest at high tide. The granite and marble used for walkways, benches, and alcoves that are part of the piece were salvaged from a gold rush–era cemetery.
