In 1904 a prospector calling himself J.C. Brown claimed he followed a curving tunnel deep into Mount Shasta and found a walled chamber of relics, giant bones and sheets of gold. Thirty years later he surfaced in Stockton, recruited an eighty-man expedition, and vanished the night before it was to leave. No cave was ever found. And to be clear about the real geology: lava-tube networks like Pluto Cave and the Lava Beds are genuine connected systems within their OWN volcanic flows, but no documented cave system links Shasta to Lassen or beyond. That through-mountain tunnel lives here, in folklore.
