In 1933, mining engineer George Warren Shufeld related stories, told to him, of Hopi legends describing a race of "Serpent People" (not reptilian, but so-named for their reverence of the lizard) who, 5,000 years ago, built several great underground cities near the Pacific Coast , including one beneath Los Angeles. The cities were said to have been built underground as protection against great cataclysmic fires on the surface.
