Another view of the old lookout. In 1926, the physicist A. A. Michelson mounted a system of lights and mirrors on this peak which, in conjunction with apparatus on Mount Wilson, 22 miles to the west, permitted measurement of the speed of light. This peak is on the Hundred Peaks Section List and a hiking description is here: Lookout Mountain
