New Almaden miners' ghost stories at Almaden Quicksilver

The New Almaden Quicksilver Mining District preserves remains of mercury (quicksilver) mining that began in the 1820s and continued into the 20th century. The New Almaden Quicksilver Mining Museum and surrounding park are focal points for local lore about ghost miners, unexplained sounds, and spectral figures reported by visitors and some tour guides. These haunting stories appear in local oral histories and guide narratives but remain anecdotal and unverified by scientific investigation.
