Speed-of-Light Experiment
From this location instruments reflected light in 1926 to Mount Wilson, 82 miles northwest. The work was one of a series of experiments conducted by Nobel Prize-winning scientist Dr. Albert A Michelson to refine the value of the speed of light. Although smoke generated in the valley below prevented measurements from being taken, the experiment encouraged Dr. Michelson to devise more accurate means of measuring the speed of light.
