Regarding Speed-of-Light Experiment. Dr. Michelson was the first American to win a Nobel Prize in a scientific field. He spent more than 50 years studying light. Two concrete foundations at the Pine Cove site, a pyramid and a square block, both of which still remain, supported equipment for the experiment. The foundations are approximately 50 feet apart, with their tops at identical levels. A tube between them held mirrors to reflect the light back to Mt. Wilson, where it was to be measured. The Riverside Historical Commission had placed a marker at the site in 1969. SOURCE: Billy Holcomb Chapter 1069 35th Anniversary Plaque Book by Phillip Holdaway
