Paleo-Indian Metalwork

The ability to use and work with metal was previously unknown to exist with any Native American peoples. The technologically advanced California Paleo-Indians had this capability for hundreds if not thousands of years. 
After each eruption, beads of copper and other metals were collected and then remelted by the super-heated steam rising from the vents in the caldera floor.  The now pliable metal was then made into the shape of standard tools and cooled.
