The photo on the left was taken in 1905 from "Electrical World, Volume 48". The photo on the right was taken in 2012 within a 10ft radius of the original photograph. This hydroelectric plant used unreported Fred Locke #303 insulators and fed two different cotton mills. Notice that it was expanded in the 20s on the right side. On the banks next to the tailrace are large stones taken from the tailrace. I searched all of the woods around the plant with no trace of an insulator dump.
