NO. 852 NORTH BLOOMFIELD MINING AND GRAVEL COMPANY - This was a major hydraulic gold-mining operation in California. It boasted a vast system of canals and flumes, its 7,800-foot drainage tunnel was termed a feat of engineering skill. It was the principal defendant in an anti-debris lawsuit settled in 1884 by Judge Lorenzo Sawyer's famous decision, which created control that virtually ended hydraulic mining in California.
