According to legend, JC Brown was a British prospector who discovered a lost underground city beneath Mt. Shasta in 1904. Brown had been hired by The Lord Cowdray Mining Company of England to prospect for gold, and discovered a cave which sloped downward for 11 miles. In the cave, he found an underground village filled with gold, shields, and mummies, some being up to 10 feet tall.

Thirty years later, he told his story to John C. Root who proceeded to gather an exploration team in Stockton, California. 80 people joined the team, but on the day the team was to set out, Brown did not show up. Brown was not heard from again.
