New Almaden Quicksilver Mining Museum and miner ghost lore

The New Almaden Quicksilver Mining Museum preserves the history of the 19th-century mercury (quicksilver) mines that operated in the Almaden area of San Jose. Local folklore and regional paranormal accounts claim the mining camp and shafts are haunted by miners who died during mining operations, and these stories have been repeated in guided tours and local histories. The museum and Almaden Quicksilver County Park document mining accidents and community history while noting that supernatural claims are anecdotal and unproven.
