Cavedigger: Ra Paulette digs cathedral-like, 'eighth wonder of the world' art caves into the sandstone cliffs of Northern New Mexico. Each creation takes years to complete, and each is a masterwork. But patrons who have commissioned caves have cut off nearly all of his projects due to artistic differences. Fed up, Ra has chosen to forego all commissions to create his own Magnum Opus, a massive 10-year project.
