Calaveras County is steeped in history and frogs—thanks to Mark Twain—but it was a recent discovery and surprise for us. The Spanish word calaveras means “skulls” and was said to have been named by Spanish explorer Gabriel Moraga, when he found many skulls of Native Americans along the banks of the now Calaveras River. He thought the cause was famine or in-fighting, but most likely, it was was from European epidemic diseases. Gold prospecting in Calaveras County began in late 1848 with a camp founded by Henry Angel—now known as Angels Camp. Another mining town, Murphy’s Camp—now Murphys—was founded by John and Daniel Murphy who crossed the Donner Pass two years before the Donner Party.
