California’s deserts have sparked the imaginations of millions of people around the world. From the famously alien landscape of Joshua Tree to the wide expanses of seemingly empty land, the desert has been seen as a place of reinvention, a blank slate to create your dream. This episode explores how those dreams have led to the man-made natural disaster that created the Salton Sea; to the effort to preserve Joshua Tree National Park; and how commercial interests and real estate developers created desert utopias like Palm Springs.
