Located below the Death Valley in California, the Shin-Au-Av is a series of tunnels believed to be 5,000 years old. We don’t know exactly who built them, but the indigenous Paiute people have many stories and legends describing the site. The tunnels house mummies, artifacts, and other records of an ancient civilization that would otherwise be lost to history.
