North Bloomfield Mining and Gravel Company

This was a major hydraulic operation in California. Its vast system of canals and flumes using a drainage tunnel 7800 feet long was termed a feat of engineering skill. It was the principal defendant in an anti-debris lawsuit settled by the Sawyer decision in 1884. Judge Lorenzo Sawyer's famous decision created control that virtually ended hydraulic mining in California.

Plaque placed by the State Department of Parks and Recreation in cooperation with the Malakoff Citizen's Advisory Committee and E Clampus Vitus, No. 10. June 11, 1972.
