In 2013, Jack Dublin and family traveled to the Grand Canyon for a week of whitewater rafting. When a monsoon rolled in, forcing them to higher ground, they sheltered in a cave unseen for nearly 150 years. What they found inside -- several journals from the time of the Gold Rush -- revealed miracles and magic, fables and fortunes, scattered treasures of the ages from sea to shining sea (and deep beneath them as well). The legends tell of explorers who harnessed ship and beast and rail to lay hold their dreams on a merciless frontier; exploits that elevated ordinary men into heroes, and the undoings that destroyed the rest. One man lived long enough to record the greatest history never told... until now. Discover why an anonymous authority calls the journals "the greatest discovery since the Dead Sea Scrolls."
