Slab City is an unincorporated community located in California's Sonoran Desert, near the Salton Sea. It is known for its unique, off-grid lifestyle, attracting a diverse group of residents, including artists, retirees, and those seeking an alternative way of living. The area was originally a World War II military base, and the concrete slabs left behind serve as the foundation for makeshift homes and camps. The community operates without formal government or utilities, relying on solar power and water deliveries. Slab City is also home to various art installations, including the famous Salvation Mountain, a colorful, man-made mountain covered in biblical and spiritual messages.
