The Quiksilver Mines of Silicon Valley and Mercury Manufacturing in New Almaden, California
Mercury was mined commercially in Silicon Valley until 1976. The Quiksilver Mines of New Almaden, California, a few miles from the city limits of San Jose, California produced during the 1940’s and 1950’s more mercury than any other mines in the world. The mines are now part of a sweeping, vast, beautiful park in south San Jose — the Quiksilver Mines County Park.
