North Star Mine Powerhouse

The North Star Powerhouse, built by A.D. Foote in 1895, was the first complete water powered compressed air transmission plant of its kind. Compressed air, generated by Pelton Water Wheels, furnished power for the entire mine operation. The 30 foot Pelton Wheel was the largest in the world, and was in continuous use for over 30 years.

Plaque placed by the State Department of Parks and Recreation in cooperation with the Nevada County Historical Society, May 15, 1971.
