Pelton wheel
Hans Ewoldsen, the Saddle Rock Ranch foreman, built a Pelton wheel on McWay Creek in 1932. He worked in the machine shop of the highway construction crew, using hand-split redwood from the canyon and other materials he bought. The undershot wheel ran a 32-volt generator and was the first electric power in the Big Sur area. It supplied power to three residences, a blacksmith shop, and the Funicular railway.
